After using up the whole bottle, I can tell that actually my skin does look more even and more youthful. It is a very mild effect since the product is not a chemical peel, but a very nice subtle change. I will definitely reorder, my skin really likes this peptide formula.

Amazing skincare, I use it in the evening then apply cream of Etude moisture cream. They are so good together. Klairs and Kahi products are all amazing. They are my must have now.

Macht die Haut schön weich & feine Fältchen werden tatsächlich geglättet. Für mich besser verträglich als Retinol-Produkte

I am using it since one month on non-retinol nights and during the day and it really transforms skin texture and has almost immediate effect. Will buy again for sure!

Only used it for 3 or 4 days, considering my age (60) I expect no miracle but an improvement by the end of the bottle.
