  1. Lorett M

    Love this product! My skin is glowing every time I apply it in the morning…I am surprised that has already lightened up sun spots on my face and my ultra sensitive skin tolerates it.

  2. Marty

    Great price and quality! I’m already seeing a difference with how bright my skin tone is with just a week of use. I also love how moisturizing the serum is; my skin actually feels healthier once I put it on. Definitely recommend!

    A mighty product ❤️

    Amazing product at a good price.

    I use to use another skin company that makes the same products that are extremely overpriced! Cosmetic Skin Solutions give you the same quality with great result for a much better price! I have seen a difference in my skin with these products. Will continue to use.


    All Cosmetic Skin Solutions products are better than other companies such as the skinceuticals, obagi, cellex-c, mad hippe, I mean A LOT BETTER and inexpensive!!

  7. Leticia

    This is part of my daily skin care regimen that I apply before my moisturizer and sunscreen. I won’t ever leave my house without applying it in the morning and, even when I don’t go out, I still use it religiously. It feels slightly thick but absorbs quickly into the skin. This product does magic on my skin.

  8. BK in FW

    This product is awesome for your skin care regimen. I’m 61 years old and I use it on my face, neck, chest and hands. I then apply moisturizer. It makes a big difference in such a short time!

  9. Kat D.

    Can’t live without this product. Use it under your spf during the day for extra protection from free radicals and sun damage.

  10. Kathryn

    Can’t live without this product. Use it under your spf during the day for extra protection from free radicals and sun damage.

  11. Amelie

    This is another one of my favorite CSS products! I use it along the Phyto + gel serum and I can say that my usually congested, uneven, pigmented skin has never looked so good! This is GREAT for oily skin as it doesn’t clog your pores like other vitamin C serums. My acne scars and pigmentation have significantly faded. Keep in the fridge for best results!

  12. Nadia

    It’s been about 2 weeks that I’ve been using this and I love it so far! My face is so smooth and I can feel it tightening up! So far so good! :)

  13. Rachel

    Love love love this serum! Better than the comparable brand name that is 3 times the price!

  14. cyt1961

    Amazing product! I’ve been using this for about a year and it’s made a huge difference in my oily. congested, large pores. My skin is much more even, refined & dewy under makeup. Best skin I’ve ever had and I’m in my 50’s!

  15. Monica Scheurer

    So happy I found this product. The woman that does facials for me gave me a sample of this product from a very pricey competitor. I really like it, but not the $160 price tag. So far so good. I use this on my face, neck, chest, and hands. I’m 40 now and feel like I’m equipped and ready for battle with aging.

  16. Spricefl

    So far love how it makes my skin feel! My skin also appears brighter on tone.

  17. Roxy

    I am a licensed aesthetician and have used other pricey brands but this brand is absolutely amazing!! Never again will I use the more expensive brand when I can get the same thing at a much better price. This serum leaves my skin glowing and I can already see a difference with a few dark spots I had that are fading after one bottle.


    Llevo usando este serum desde hace un par de años y realmente funciona. Enhorabuena al equipo de Cosmetic skin solutions.

  19. Zebraegray

    I love this product! It has made a noticeable improvement in my skin tone and in the appearance of fine lines and wrinkles. I was using another professional skin care line but due to the cost I had to stop. This product has exceeded my expectations and the cost is very reasonable. I can highly recommend it and have!

  20. Zebraegray

    I love this product. It has made a noticable improvement in the appearance of my skin and has evened out my skin tone. I was using another professional skin care line but could not continue due to the cost. This product outperforms the other and the cost is reasonable. I can recommend this product with confidence.

  21. Megan

    I love this product. I had previously used a similar product line and was hesitant to try a new one. I am over the moon excited that it is the same product but a fraction of the cost. I actually like the texture of this one better. It isn’t as sticky. I am excited to try more and now a loyal customer!


    I have used this serum and the C Ferulic for many years. I started with the expensive original from the competition but discovered that Cosmetic Solutions is just as good and effective a product. I travel a great deal and never leave the house without it. In the summer, I only use this and sun screen!

  23. Marlene

    Love, love, love this stuff! A girlfriend has another brand with the same % of the good stuff but she paid $160 dollars for hers! My skin is glowing after only 2 weeks of using this as directed! I also use the B5 serum overtop of it for hydration! Both are fragrance free which is big for me because fragrances tend to cause dark circles and bags under my eyes…sort of an allergic reaction.
    I am so happy I found these products! And I am loving the compliments that have been coming my way already! Thank you!!!

  24. Sandra Thorpe

    I just started using Cosmetic Skin Solutions Products and after just 2 weeks I can see the difference in my face. I wanted to try PHLORETIN C=F SERUM because it promised to help to reduce age spots and even skin tone. Well, it sure lives up to its name. After just two weeks I can already see that the spots have been lightened and my skin tone is getting more even. I love it!

  25. Julie

    Another great CSS product! I use this on my face. It has visibly reduced discoloration. I apply a few drops to the back of my hand and then use finger tips to apply to forehead, nose and cheeks.(then rub the backs of my hands together to distribute remaining product over backs of hands) Not only has it reduced dark spots on my forehead, I had some freckling on the backs of my hands that have completely faded away! I have very oily skin on my face and this has helped reduce the oil. I use this product on the oily areas and the CE serum on the areas that aren’t oily such as around my eyes, my neck and chest, great products!

  26. Jeannine

    Wonderful product, it really evens out my skin tone and helps correct hyperpigmentation and sun damage. Very light, not heavy, it absorbs completely into skin. I have a very sensitive acne prone skin and this product does not cause any irritation or breakouts.

  27. Jamie

    Wonderful stuff. I read that phloretin can prevent the degradation of your elastin, which is the support structure of your skin. The vitamin c will boost collagen too! I use this every morning, under my sunscreen. Of a night time I use the vitamin c serum to amp up collagen production!

  28. Vickie

    Great serum! I used the same formula from the Skinceuticals brand which is over twice the price and have had similar results with this brand. I saw increased clarity and smoothness in my skin with both. It does not break out or irritate my sensitive skin. I’m glad that I can now find this available at a more affordable price! I’ve used it for 2 years and believe it has really improved my skin. High quality ingredients at an affordable price. would definitely recommend to my friends and family!

  29. Mano Capano

    Great product. I bought it for my husband who has a lot of age spots and rosacea. His skin is very fragile and this product worked perfectly! It performs like Skinceutical’s Phloretin CF serum at less than half the cost.

  30. Bearbear

    Love this product. My face feels and looks soft and refreshed. Thank you CSS.

  31. Katie

    This is very good product, my skin look better, I use this with Phyto Serum.

  32. Alice

    Great product comparable to Skinceuticals for less cost!

  33. Ines

    I love walking every day. I live in SC where the sun is intense. The only product that has protected my skin from the sun is Phlorentin Serum which is great for my oily skin. I love this product!! Thanks CSS :=)

  34. WinonaWW

    My dermatologist recommended phloretin and Ferulic acid manufactured by a different and considerably more expensive company, but she is impressed with how this works and has encouraged me to continue with this. This is a very effective serum that keeps spots to a minimum and general signs of aging at bay. Three or four drops in the evening does what needs to be done.

  35. Samantha Campregher

    Amazing is the only word to describe PHLORETIN. My skin is soft, bright and looks like a baby. I am really happy.


    Review: I love the Phloretin Serum. I have some sun damage and this product has worked wonders. My skin is much smoother and the dark spots are fading. My fine lines and wrinkles are also disappearing. The serum is lightweight and absorbs instantly. I do not have to use heavy moisturizers as I did in the past. Sunscreen and make-up apply smoothly over the serum. I have used other serums on the market and none compare to the Phloretin C+F. Also, Cosmetic Skin Solutions price for this serum is much less than other brands with the same ingredients. I highly recommend this product and will never be without it.

  37. EE

    Hands down an essential part of my face regime. Although its not as pricey as other companies, what is your face worth? I will be a forever customer!

  38. Rosanna

    I have been using this product along with many of the other of the cosmetic skin solutions products. They have active ingredients at a great price. Other products that I love are daily moisturing crime firming eye gel vitamin c+e and the hydra b5 masque. They have all the active ingredients of another company at an affordable price. I highly recommend these products.

  39. Tamra

    This product has changed and improved the complexion of my face and skin tone!! I’m very pleased. Amazing!!!

  40. Rachelle

    I love using this product, I have very sensitive skin and easily get freckles and brown spots when I spend too much time outdoors. This product help me lighten those dark freckles and brown spots. I am in my late 20’s and would recommend this.

  41. Vickie

    Wonderful serum. I have used it for over a year and my skin is much improved. Love it!

  42. Maria Victória

    FANTASTIC!!!!! I really like this vitamin C serum, it lightens so WELL!!!

  43. Susan

    Like all of the CSS products I use, I love this serum. I alternate between this, the Phyto, and the B5. This has definitely lightened pigmentation from sun. Highly recommend this (and all of the other products!).

  44. Garine A

    Phloretin Serum works best for me due to my combination oily skin and I follow up with Hydra B5. I love the feel of it and my skin has never looked better! Thank you.

  45. David

    I’ve been using Phloretin Serum for about a month now along with Phyto Botanical Gel. At night I alternate with Resurfacing Serum and Retinol. All of these products are wonderful, and my skin has never been in better condition.

    I’ve used the high-priced equivalent products, and I cannot tell a difference.

  46. Cindy

    I had been using another companys 12% serum along with another hyaluronic acid serum and decided to give CSS C+ phloretin a shot. My immediate thoughts were- it’s thin, it smells like alcohol, it won’t do anything. But you use a tiny amount and it really does help to hydrate your skin and brighten it. And I’ve been getting fewer dark spots and burns (I also use phyto and daily sunscreen, but used sunscreen before) so it does seem to help protect. And the cost is the same monthly as my previous separate serums. It’s a great investment in skin improvement.

  47. Kate K

    I used the Skinceuticals Phlorentin serum however I like this one much more. It is less harsh on my skin. I have adult acne prone skin. I am finishing my first bottle. Really happy with the product.

  48. Angi

    I am so enthusiastic about this serum (and about other CSS products like Vitamin C+E Serum in combination with Hydra B5) that I even order it from Germany several times a year.
    CSS Phloretin helps diminishing my brown marks and draws a kind of glow over the entire face. Besides, I love the nurturing effect…

  49. Lisa

    I ordered this serum recently after using the 20% vit c serum and I love this too, I have oily skin so I think for the summer this will be best for me but honestly I haven’t found one product in this line that I havet liked, the results are there! the cust service is amazing and I will keep ordering everything they offer and look forward to new things as well. This serum is fantastic!

  50. Irene

    I love this product and the price is great compared to others. It really works and the idea of natural products. I only use natural product on my body from head to toe

  51. Vicky

    I bought this along with the Phyto gel which have significantly reduced my pigmatation marks (see my Phyto gel review. The serum absorbs really quickly…it does tingle a little due to the active ingrediants. In only 2 weeks my discolouration has improved…not sure if its down to one or the other, but as a combo they work really well together and will continue to use. Really delighted with this product!

  52. Le

    I have been using this product since 07/15/2012 on and off ,just because trying different products included very high-end at a department store. So far I found Cosmetic Skin Solutions product is amazing. Skin drastically improved just in a week, it really works. I love Vitamin C+E or Phloretin followed with Hydra B5 it makes my skin glow, even skin tones and wrinkles on my fore head are gone. I am very happy with the result and continue using CSS products.

  53. Sharon G

    I use this serum daily w/ the Retinol 1.0 crème. Love how my skin looks and will continue this regime. I was so thankful to come across CSS products after paying triple for another serum with the exact same ingredients!

  54. Trish

    I was using the more expensive brand that makes these vitamin c serum . I got this because it is WAY more affordable, and it is worth 3x the price. I’m in love with this serum. I’m about to turn 24 and I have seen such an improvement in the brightness of my skin. I worked at a big beauty chain store and I have tried so many products but after ONE use of this serum I saw such a change in my skin. I highly recommend this with the b5 serum and I’m looking forward to buying ALL of the cosmetic skin solutions products. I’ve already decided to order a combo pack for my mom!

  55. Tameka H

    I have been using this product for almost 2 years and I really like it. Not only is it very price competitive to Skinceuticals Phloretin but it is just as effective. It absorbs right into my skin. So from now on I will continue to by my serum from CSS. I only hope that they come out for more competitive products in the future

  56. Beata

    I have been using Vitamin C serums and B5 moisturizer for over 10 years and since they are usually very expensive I was trying to find something more affordable. When I found this company few years back I was skeptical at first but decided to order. I have been using this and other products ever since with a great satisfaction. I do not leave my house without Vit C serum on my face.

  57. Michaela

    I love to spend time outdoors but over the years my skin tone had become blotchy and uneven. I’ve been using the Phloretin serum for about a month now and it has greatly improved the tone and texture of my skin. I also use the B5, eye, and resurfacing serums and last winter used the C+E serum. I’ve found all of these products to be highly effective and use them as the cornerstone of my skincare. I highly recommend this brand.

  58. Susan

    My go to product to improve the way my skins looks and feels. I’ve used others in the past that were not affordable and didn’t work half as well. But now that it’s affordable I actually use the product as intended and see the results. I switch between this for the summer and the C+E (during winter) to help my skin maintain proper moisture. This product line is awesome and works well together.

  59. Lena

    I adore this serum. I noticed results almost instantaneously – it made my skin glow a lot and improved the overall texture as well. I highly recommend this product and will continue to use it.

  60. Erik

    I’ve used this serum for the past 3 years since I found out about it.
    Twice a day, after cleansing once in the morning and before bed.
    I’ve seen the results almost immediately. My skin feels and looks smoother and less spotty.
    Usually there is a tingly sensation right after you put it on.
    I would recommend you to try it. You would love it too.

  61. CC

    This product helped acne that even my dermatologist could not fix. Awesome stuff. Just like the $200 product made by Skinceuticals. Awesome Product!

  62. Lynn

    Sure has helped the dark “age spots” and sun damage. My skin feels softer, too. Will keep this active!

  63. Liviyha

    I love this Product. I have used another market leading brand for years ( nearly triple the price) and this one matches it hands down and surpasses it on price, my skin is so much brighter when I’m using it and it helps to keep my Melasma at bay.

  64. ZK

    Wow, is all I can say in regard to the Cosmetic Skin Solutions Brand. For years I would purchase another more expensive brand, but only one bottle here and there due to cost. Since I have discovered this company, I now purchase much more at a time and much more often. I use different Vitamin C products all year long now and have even shared with my kids to give us all the best protection from the sun. My brown spots have slowly been fading, my wrinkles are diminished and I get complements regarding my skin often. I am so grateful for the product and the affordable prices. Thank you!! Please keep adding to your line of products. I love them!!

  65. Kate W

    I have rosacea, as a result my facial skin doesn’t tolerate high concentrations of Vit C at all well – I look a bit like a tomato. This serum is just perfect because I feel happy knowing I am getting the anti-oxidant benefits of the Vit C, but without aggravating my skin, and the phloretin calms the redness down further. If only I’d found this stuff years ago. Thanks CSS!

  66. Laura

    This is my go-to antioxidant now that I have found CSS. I use to go broke with that other brand and now I can have all of the benefits without breaking the bank. I have been very happy with this product and will keep ordering.

  67. WinonaWW

    This produce is as good as that sold by the other, larger, and more expensive providers of this combination of ingredients but costs only 30% of what the two major providers sell. This prepares my skin for moisturizer, corrects some sun damage, thus reducing fine lines and wrinkles, and evens out sun or age spots. Absolutely essential for healthy skin. With Phyto-serum, this does everything anyone could want.

  68. Melissa F

    This product has dramatically improved my pigmentation. I have less brown spots in since I have used this in the last month. I used to pay $200 for a product that had the same ingredients and I’m pleased to say I’ve saved $160 and have the same effect! Would highly recommend this product to anyone looking to even out their skin tone

  69. MelissaT

    This serum is wonderful. It really does work and in my opinion is the same as the more expensive name brand product that I have used in the past but dreaded paying the $130 dollars for! You have to try it – I am telling all of my friends about how well it performs

  70. MIG

    SAME EXACT RESULTS AT LESS THAN HALF THE COST OF SKINCEUTICALS! I used to buy the C serum only from Skinceuticals, spending 120 bucks a bottle. It worked ok, but the cost was killing me. It was just about that time for me to get a refill when I found this company. I was skeptical, but desperately wanted to believe that I could save so much if it actually worked. I took the plunge and bought their c+e ferulic serum. A few months later and I am positive it delivers the same excellent benefits sckinceuticals does. My skin is wrinkle free and continues to improve on clarity. I have heard all the buzz around Phloretin and was happy to know that this company had it in their line of skin products so I tried it.

    A month later, I am more than happy with the results. The brown spots I had on my cheeks continue to get smaller and smaller by the week. I have found nothing that would make it fade or at least make it seem lighter until I started using this serum. My skin looks vibrant with a beautiful glow to it. I am also amazed at how it makes your skin so smooth and radiant. I am 40 years old and have been getting compliments lately about how great my skin looks. So tonight, I decided to write this review, which I rarely do, but this stuff works. I also find it more effective if you apply this after using the Clarisonic. It just prepares your skin for the serum to be absorbed more easily. After applying the serum, I use my normal Cosmetic Skin Solutions Day Moisturizer which works wonders for my skin as well. The serum is light, easily glides all over your skin so you only use a few drops. All in all, money well spent which makes me very happy.

  71. Shona

    I love this serum, I used a far more expensive Phloretin CF serum for years and this is the same if not better.

  72. Gloria C

    I love the Phloretin Serum. I have some sun damage and this product has worked wonders. My skin is much smoother and the dark spots are fading. My fine lines and wrinkles are also disappearing. The serum is lightweight and absorbs instantly. I do not have to use heavy moisturizers as I did in the past. Sunscreen and make-up apply smoothly over the serum. I have used other serums on the market and none compare to the Phloretin C+F. Also, Cosmetic Skin Solutions price for this serum is much less than other brands with the same ingredients. I highly recommend this product and will never be without it.

  73. Singh S

    It is an excellent product! I have noticed great improvement in skin texture, skin looks
    , brighter and more youthful appearance and of course it gives me more self-confidence at work and among friends. Dark spots seem lighter with continued usage.

    As compared to other products, I like it because it absorbs quickly, gives my skin a glow and is non-greasy. I’m not big fan of make-ups, but I do use use make-ups over it occasionally without an issue.
    I have send it as gift to my mom and sister abroad and have heard similar reviews!

    Excellent product and price you can’t beat! Go for it!

  74. Alexi Gomez

    My derm recommended that i start using an antioxidant serum and a serum to help reduce pigmentation from the sun and acne scars. The brand she recommended was way too expensive to continue buying on a regular basis, so i started looking for similar products. The results from CSS are the same as the other expensive brand, in fact i noticed more results after switching. I use the Phloretin C+F serum and the Phyto+ serum, After applying i don’t need to use a moisturizer (one less product to buy!) My skin has cleared up amazingly; not only has my skin stopped breaking out but the spots are almost gone after only a month of use. I highly recommend this brand, especially for those of us on a budget!

  75. Krystal R

    I have never used any type of serum before and being an outdoors person I’ve noticed some blotching beginning to develop on my skin. Having an oily skin type, I decided to try PHLORETIN C+F SERUM, I’ve been using this serum for a little over 4 weeks which has drastically improved the look of my skin.

    This handy size bottle is not only convenient in size but also in price to similar products which cost as much as $150.00-$200.00. This serum can be applied even under sunscreen, it’s a light weight serum that I even forget that I’m wearing. It balances my skin tone evenly and has corrected sun damage. I love it.
