New Skin @ 60+

Since using I've noticed a vast difference in my skin! Its softer and clearer; haven't seen any wrinkles disappearing but not as noticeable! The peel is great too!! Thanks:)

Affordable luxury that works!

I absolutely love this serum! It is thick and luxurious and I see a difference in the firmness of my skin in just two weeks time! I can’t wait to see with continued use!

best serum I've ever used

First of all. the product looks good and feels wonderful going on the skin. It's an effective base for both my day and night moisturizers. I would highly recommend this product. I have felt and seen visible subtle changes in my skin after about three weeks of use.

Very smoothing

Living in a dry climate this serum is very hydrating without being oily. It absorbs quickly into the skin. Within a couple of weeks I noticed my fine lines were less noticeable.
