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!

Humectant, Masking, Skin Conditioning

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.
  • It has mild preservative properties.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Skin Conditioning

Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Buffering

Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.

Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.

"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Great price, great ingredients, fresh. I notice the effects in my skin. Big but not for sensitive skin. I am an stubborn girl so I made it work. For a long time my morning routine was this and a lot of Centella and oat and hidrating essences just to stop my skin from reacting. Now I can use it without worrying but I need a calming essence immediately after it.

Only 3 days using it and I'm impressed, my skin barrier is stronger and my acne is starting to fade quicker than the other formulas l've tried. I have sensitive skin and my redness has improved, I'm starting to fall in love 😍

WORTH THE HYPE! I’ve been using azealic acid for since 2021 and I swear it’s the best acne, post acne scar, and dark spot treatment out there. When I saw Anua come out with this, I had to get my hands on it cause I’ve been using ANUA for quite a while and it was fungal acne safe which was a huge plus for me! I’ve had a huge breakout problem in December and I’ve been using this serum since then and Show more
