I can already see some of my lines fade around my eyes (not yet the forehead those are deeper and Botox fixes those anyway!) I don’t use it 2X a day all the time and I haven’t used it every day! I purchased on Black Friday it got to me about a week later so in that amount of time I see a difference. Definitely a staple in my skincare routine 

This serum is a multi-tasking machine and a part of my winter regimen for extra boost of deep hydration and restorative action.  It absorbs quickly, nice light texture - and I haven’t had any irritation from this product at all!  It helps with fine lines and uneven skin tone, bringing out brighter complexion and plump skin.   The product lasts me about 4 months (I use it twice a day, 2 -3 pumps per use). 

I have been using this for 6 years. It has helped my skin stay healthy and glowing.

I have tried other products and this one beats them hands down. I have seen a significant improvement in my skins texture, firmness, lines and it protects against the harsh environment I work in.

I was using another hydropeptide serum. I like this one better. I saw a difference in my skin right of way. Love it!!!!

I love all of my Hydropeptide products but this serum is the best! I always get compliments on how good my skin looks and it all starts with a a good serum!

This is probably the most overall effective product I have found for my face. I love the way it helps to make my skin smoother and firmer, and helps heal at the same time, as I am sometimes prone to breakouts. I'm on my second purchase of this product, and I already feel that it does what it says it does regarding overall good facial appearance. I love this product!!!

I love this serum. It moisturizes and gives my skin a nice glow. I haven't been using it long enough to know how it works with wrinkles but I do feel firmer. Also, it works well under makeup which is a plus for daytime use.

After careful study of ingredients in different skin products, I am certain this is either the best, or one of the top best, as far as "doing something" to stop or ameliorate the aging process. A little goes a long way, applying only to areas where those pesky wrinkles are forming (how DARE they!!!). I am using it under the Hydropeptide moisturizer, and will keep "faithful" to the brand!

I really like this product. I myself have never bought this one, but my esthetician has used it on my skin. I was suppose to purchase it and bought the wrong one. I bought the one in the lighter blue bottle. The refining serum (I think is the name). It works as well but I REALLY like this one. I really liked this when my esthetician used it because it helped hydrate my skin as well as clear up some of my dark marks. I get really dry around my nose in the winter and this has really helped. It also does wonders on my dark marks.
