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.

The Ordinary Multi-Peptide Serum for Hair Density 36 ingredients
It certainly has a positive effect. Even though I have sebderm it does not break me out much, even with all the oily ingredients.
It is not too hard to apply and overall I am happy
