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!

Buffering, Masking

Azelaic acid is a naturally occurring acid derived from grains. This ingredient is effective in treating acne, rosacea, and other skin conditions.

It has been shown to reduce the growth of acne-causing bacteria and helps reduce inflammation. On top of that, it helps reduce the production of sebum and unclog pores.

Azelaic Acid also has antioxidant properties. Antioxidants protect our skin cells from free-radical damage.

One of the main benefits of azelaic acid is that it is gentle and well-tolerated by most people.

Fun fact: The lab-created form of azelaic acid is typically used within cosmetic products for its shelf-stability.

An effective azeleic acid serum. One of my gripes about Azeleic products is normally the texture and how it settles powdery or pilling. This however is elegant emulsion feel, spreads well and doesn’t pill! Really helped with my texture and overall. There is a slight smell (not fragrance) but it doesn’t bother me, disappears after a few seconds.

Love it. When hot outside it’s enough as a moisturizer as well. Makes skin soft, reduces acne and decreases redness. Stings in the beginning, but once skin is used to it, it stops.
