it works better than any other vitamin C product I have used and I can see results

I like the texture of Timeless Vitamin C serum. It’s also effective in brightening and firming. However the 20% formula is a bit too strong for my sensitive skin. I can only use it a couple of times a week. The 10% formula is just perfect. It’s less irritating, so I can use it everyday.

I liked this serum because it does not irritate my skin.

Non irritating for my dry, sensitive and sometimes combination skin. Best alternative to 20% Vitamin C with the same results!

Love it!

I love the look and feel of this serum. I wish all serums would come in an easy to squeeze bottle like this.
