The Ordinary Alpha Arbutin 2% + HA 12 ingredients
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.

I really wanted this to work, and I gave it three attempts over a few months, but every time I used it it gave me irritation in the form of little red dots on my upper cheeks and nose (I never get acne in these areas). It may just be too strong for me.
