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!

Antimicrobial

Mandelic Acid helps exfoliate skin. It also contains antioxidant properties.

As an AHA, Mandelic Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Mandelic Acid may be an alternative to Glycolic Acid for those with sensitive skin.

Mandelic Acid may help reduce wrinkles, acne, and hyperpigmentation.

Humectant, Skin Conditioning

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.

Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.

Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.

These are some other common types of Hyaluronic Acid:

This alone cleared up my acne. I have tried product after product after product for over a decade and my acne persisted until I got a hold of this mandelic acid. I even noticed when I got lazy and stopped using this that small breakouts would start again. This cleared them right back up again! It does pill, however, which is no big deal for me because I use it at night. But the bigger issue is Show more
