Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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!

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.

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.
Learn more about Xanthan GumSodium 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.
Learn more about Sodium HydroxideEthylhexylglycerin (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.
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.

unfortunately broke me out really badly after 1 week use.
After using this for a few weeks I was amazed at how well it improved my skin’s texture. I have to take corticosteroids for life, which has thinned my skin substantially, which in turn has made my skin very susceptible to eczema and scarring from even the smallest acne spot. This has made my skin plump and healthy looking once again and made it so when a spot shows up, the scaring is almost Show more

unfortunately i cannot use this product anymore as i have developed FA, but before that this was my HOLY GRAIL! i used to have immense CC on my nose bridge as well as redness on my cheeks circa end of 2021. i started using this i believe winter of 2021-2022 and by the time spring rolled around (around 2-3 months) the redness, PIE, CC were gone or barely noticeable. i have used this product up Show more
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
