Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

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!

Preservative

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent 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.

This says it's fungal acne safe but on the website the ingredients says it has castor oil extract or something in here, personally I avoid anything with castor oil so beware.

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 Show more
