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 will find better things out there.

This wasn’t completely destructive to my skin back in my late teens (dehydrated oily-combo skin with hormonal acne I assume) but there’s a reason why I only aimed to finish my tube of this. Doesn’t cleanse very deeply so I felt I needed to use more product (I was oily, sweaty, and in a very place with very polluted air), and tends to leave me more dry after use. I think I remember it being mildly stinging and irritating, leaving my skin feel more raw afterwards rather than just refreshed and clean. May have also left a residue after washing.

Just, please look for something else. You can find something better, even for a lower price point.

works great on my oily skin, cleanses while not being stripping, so it doesn’t leave my skin feeling tight. 10/10 :)
