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.

Skin Conditioning

Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.

There are two forms of panthenol: D and L.

D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):

Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.

This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

This ingredient is also referred to as pro-vitamin B5.

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

  • Humectant, drawing moisture into the skin
  • Emollient, helping to soften skin
  • Solvent, dispersing and stabilizing formulas
  • Preservative booster, enhancing the antimicrobial activity of other preservatives

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

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

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Masking, Solvent

Dipropylene Glycol is a synthetically created stabilizer and solvent. It is a part of the glycol class in the alcohol family.

Dipropylene Glycol helps dissolve and evenly distribute ingredients. It also helps decrease viscosity and thin out texture.

As a masking agent, Dipropylene Glycol can be used to cover the smell of other ingredients. However, it does not have a scent.

Studies show Dipropylene Glycol is considered safe to use in skincare.

It is a little sticky due to snail mucin, but I love it, it’s calming and feels refreshing on my skin, and it really does help with PIE. (not even a month difference)

This product is effective and gentle. Noticeably improved my skin texture and appearance of pores in 1 week (using once a day only). Great active ingredients - 10% azeleic acid, niacinamide, lactic acid.

I’ve had issues of irritation and tingling from other Azeleic products but this one feels like a hydrating serum with no irritation! The texture is runny, the slight snail mucin texture is Show more
