1
What it does: Skin Conditioning, Solvent
Community Rating: Loved

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!

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and microbial growth. By itself, it has a scent that is similar to that of a rose.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

Its been a few years, but from what I remember, I got this as a "only affordable option available at the store" when I ran out of Vit C serum and needed more - and I did not like this.
Felt like a waste of money. It didn't really do anything, I didn't see my usual results.
It also, oddly, did not oxidize...for like more than a year, as long as it took me to finish the bottle. That's weird to me. I know most Vit C serums are going to oxidize eventually, so the fact that this one didn't seemed fishy to me.
