Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

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, Solvent

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 
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:

Buffering, Masking

Sodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.

Its main functions are to maintain the pH of a product and neutralize metal ions.

The acidity of our skin is maintained by our glands and skin biome; normal pH level of skin is slightly acidic (~4.75-5.5).

Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.

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.

Solvent

Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin. 

It’s often used to:

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Got this for my spouse to help with eczema, but I ended up using it too to treat a fungal acne break out. I saw improvements very quickly. Very pleased. Not much of a smell, doesn't irritate my skin. Would recommend. They also have higher percents as well.

First time using Azelaic acid and it has helped with redness reduction and my cystic acne flareups. I started using this 2-3x times a week to avoid using too many actives and I feel that 5% is a bit slow to see faster results. I think my skin can tolerate a higher concentration so I will be testing out the 10% version at some other time. The texture of the serum is on the thicker side and does Show more

most calming and hydrating azelaic acid product I've ever used! I experienced no irritation and overall this is a nice serum - but I think that might be partly because there's just not enough azelaic acid in this, unfortunately. APLB don't seem to obviously display their ingredient concentrations so I could only find one source that stated the concentration was 3-4% which isn't enough for me. Show more
