Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

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 without pilling or stickyness, which I was afraid of experiencing since some The Ordinary products have poor formulations that really mess up the product. This one, can be combined with almost any product.

And the best part, it's really inexpensive, so that's a win/win.

(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.

(Tried Jun 2022) Can't say I was particularly fond of this product mainly because of the fact that I didn't really see a difference in any of my dark spots/hyperpigmentation improving. Not sure if this is more so formulated to be stronger for those with fairer skin.
