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

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 
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.

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:

I was so excited to try a product with what seemed like no comedogenic ingredients, but I suspect all the extracts broke me out pretty badly. I’m talking deep, painful cysts. I think I saw a nice effect on skin brightness, but that’s the only upside unfortunately. This also left a chalky white residue at times.

I’m on my third bottle
Want a simple, hydrating, scentless, and affordable azelaic acid serum? Look no further! Azelaic acid is well tolerated by many and for me I’ve noticed great improvements regarding redness. There was a short period of time when I cut this out of my routine, and that’s when I noticed how much it had been doing to reduce redness in my skin. This serum also contains aloe Show more

this works so well!! it got rid of all my texture. my skin looks and feels so smooth. it’s very light on the skin and absorbs almost immediately. the only reason why i rated this product 4 stars is bc it gave me fungal acne on my forehead :( i didn’t think this product would trigger my fungal acne as it only has one ingredient (cetearyl alcohol) that isn’t fungal acne safe. but thankfully i Show more

it felt very light and was the first ever essence i used but really worked well. But the fact that it feels so light makes you want to put more because it feels like you’ve put nothing on your skin.
