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!

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.

Preservative

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

Absorbent, Emulsion Stabilising, Skin Conditioning

Maltodextrin is a polysaccharide. It is derived from starch such as rice, corn, wheat, or potato starch.

In food, Maltodextrin is used to improve the texture and thicken a product. Due to its structure, it can help create a gel texture. As an emulsion stabilizer, it helps keep the ingredients in a product together.

As a polysaccharide, Maltodextrin has moisturizing properties. Polysaccharides are a type of carbohydrate. The top layer of skin uses polysaccharides to retain water, keeping the skin hydrated.

Maltodextrin is water soluble and has a sweet taste.

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.

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.

Game changer. This stuff is amazing for fungal acne, other BHA acids were too harsh for my sensitive skin and didn’t improve any of my concerns, but this stuff is strong and non irritating. Didn't give me any new breakouts just surfaced all of my pre-existing acne. Turned all my FA into white heads in a matter of weeks. This with the ordinary 5% lactic acid serum is completely reviving the texture Show more

Very good for acne
Saw an immediate overnight change in my inflammation overnight after using for the first time, haven't had any inflammatory whiteheads since I finished purging (which lasted 2 weeks) and my skin is slightly less oily. However it did nothing really for my sebaceous filaments.

It literally pills with every product I've tried, it's impossible to use. It has a very gummy texture that never gets absorbed into the skin, it only stays on top like a silicon-y film that will ruin any other product you combine it with, and also avoiding the formula to penetrate and actually do some work into your skin. So despite it's relatively high concentration of Azelaic Acid, it takes way Show more
