This product has became a holy grail for me so quick. The Hyaluronic Acid in this serums works wonders and makes my fine lines to disappear almost completely, like no other HA product i've ever tried has done before. The Alpha Arbutin has also helped a lot with fading my post-inflammatory hyperpigmentation, that used to fade much slower with my previous routine.
And it can do all of this Show more
(Tried Nov 2022) This turned out to be one of those products that I had a bit of a hard time determining whether or not it worked even after a few purchases. If anything, I appreciated how budget friendly it was and the hydrating feel of the serum, but I can't say it did much for my stubborn dark spots.

This product was horrible for me! First I got it recommended by a pharmacist for my face, but back then it was too tingly and I stopped using it. Now because I’ve gotten a bit bacne I would use it there. Apparently I might be allergic, and now I have to throw it out for good! I don’t know who’s face can tolerate this concentrated serum :/
Worth the try for ACNE skin
I used it for about 2 years and I was more than satisfied. Upon returning on my Erasmus trip, it broke me out and made my skin dry. I don't know if anything happened during the trip but right now I don't use it. It's really good if you have taken acne treatment pills and you need smt to keep the acne away (from my experience at least).
