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

Light serum that radiates skin
I have dehydrated, sensitive-combo skin with random dry patches. I have issues of heavy products struggling to absorb or get deeper and instead break me out. Other times, light products would get in but nothing would hold it in.
With this moisturizing light serum, I did notice a difference immediately. My skin become supple, plump, and just be glowing and that's throughout the day. After a week, i found my skin clear, healthy, and stayed radiant. && to add, it didn't clog my pores!
