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. If you see this, drink a glass of water. Stay hydrated!

irritating
didn't notice much a difference with my dark spots/PIH. had to stop using it because it broke me out :(
(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.
