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.

Texture: Lightweight serum. Slightly moisturizing.
Scent: No scent
Performance: Brighten and lighten acne scar if consistently used.
Pros: Contain ceramide for skin barrier.
Cons: Contain PEG. Pump might stuck sometimes. Symwhite 377 is behind Niacinamide in ingredient list.
WRP/WNRP: WNRP (trying other lighter serum and minimize my skincare products)
