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!

Emulsion Stabilising, Stabilising

Hydroxyethylcellulose is used to improve the texture of products. It is created from a chemical reaction involving ethylene oxide and alkali-cellulose. Cellulose is a sugar found in plant cell walls and help give plants structure.

This ingredient helps stabilize products by preventing ingredients from separating. It can also help thicken the texture of a product.

This ingredient can also be found in pill medicines to help our bodies digest other ingredients.

Humectant, Skin Conditioning, Skin Protecting

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

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.

Skin Conditioning, Skin Protecting, Soothing

Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.

Some studies have shown this ingredient can promote wound healing with higher concentrations.

Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.

For the short time that I've used this serum Ive grown to love it. A great serum for acne prone/irritated skin. This serum has helped the redness in my face as well as my post acne marks almost clear completely. Highly recommended.

This serum is VERY VERY POTENT the 5% difference from the AZ 10 is a real difference, I use it as a spot treatment for now, it literally kills any inflamed acne overnight and makes it go away in 3 days, worked for whiteheads, pimples and even under the skin bumps and cysts that I felt coming to a head went back down after applying for 3-6 days. I don't know I will try and see if I can work up to Show more

Beware, this is not 20% azelic acid but only 20% azeclair serum. That’s equal to like 3-5% azelic acid. It doesn’t do much at all actually. I used it only as a starter product for azelic acid (10%). So don’t expect it to magically cure whatever real issues you might have (acne, roscea etc.), cause it won’t. It helps to reduce the purging though. So yes, if you purge it should be some small white Show more

i was so excited to try this as potassium azeloyl diglycinate is a great ingredient and this formula is so simple and unlikely to cause issues for acne etc. i was hoping it could help with sebum production along with blemishes/redness but it broke me out, not even in just the small whiteheads and small red spots i usually get but quite big whiteheads in areas i dont usually get them, it was also Show more
