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!

Emulsifying, Emulsion Stabilising, Gel Forming

Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.

Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

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.

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.

One of the best azelaic acid serums that I've ever tried! It is a bit sticky, but the results don't lie. I saw results in 1 month from using it nightly. There isn't any other active ingredients in this as well, which I really like. All of the other azelaic acid serums on the market contain BHA's and AHA's, and I personally just want a serum with azelaic acid. It also made a much bigger difference 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
