Supreme Serum 20®

Someone I follow on Instagram recommended this vitamin C serum (her aesthetician, a former Skinceuticals employee, suggested it), and I’ve been using it ever since. I used Skinceuticals CE Ferulic previously, but found it irritating and overpriced. I noticed a difference as soon as I switched to this serum. My complexion is healthier, my skin tone more even, and the price is excellent. I recommend it anytime I see someone on Reddit asking about vitamin C!

I am in my mid 50's, and my Cosmetic Skin Solutions Vitamin C Supreme Serum 20% is one of my skin care staples for anti-aging, along with CSS's copper peptide serum and Supreme Eye Reversal Creme. I plan to continue using Cosmetic Skin Solutions products for their quality and value. CSS is so generous to its customers too, sending additional samples to try. My next new product that I want to add to my regimen is the Supreme Hydra B5 gel, which I received a free sample of. The masks are also wonderful - I have tried the CBD and Supreme olive masks (samples), and my skin is always so soft and healthy feeling after I use them. I think CSS product are of high value, and I recommend them.

I have been using this serum for so many years! At 57, it has really preserved my skin and given me a more youthful glow.

My husband and I have been using this serum for years. It has made a big difference on our skin. It is easy to apply, a few drops go a long way, it is odorless and works wonders. It is easy to fall in love with a great serum like this one. Best Vitamin C we have used. Thank you CSS!!!!!!

Good stuff
