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!

I love this product so so much!! Honestly, I thought the comments were kinda exaggerating but, oh my, was I wrong. This is such a good serum. The fact that it’s fungal acne safe and non comedogenic??? And it literally has the rating 100/100 for me so props to the app/site.
No, but now to the point. This literally calms down my face so so much. As someone that had a really broken skin barrier Show more

This serum is a must-have for oily skin! It's extremely effective, especially when used in the morning plus at night. I've noticed a big reduction in sebum production on my skin, as well as a slight effectiveness on redness and marks. However, it's not very effective on active blemishes, and mainly helps to limit their future appearance. On the plus side, it's quite moisturizing.
