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.

I’m not sure why this product irritates my skin! It causes hives. Burns a little as well. Maybe it’s the citric acid? I have super sensitive skin and my skin won’t tolerate this product.

It is a little sticky due to snail mucin, but I love it, it’s calming and feels refreshing on my skin, and it really does help with PIE. (not even a month difference)

This product is effective and gentle. Noticeably improved my skin texture and appearance of pores in 1 week (using once a day only). Great active ingredients - 10% azeleic acid, niacinamide, lactic acid.

I’ve had issues of irritation and tingling from other Azeleic products but this one feels like a hydrating serum with no irritation! The texture is runny, the slight snail mucin texture is Show more
