Why we stand behind it

This gentle-yet-powerful serum contains four powerful derivatives of vitamin C that are better suited to sensitive skin than l-ascorbic acid but deliver the same results: collagen production, antioxidant protection, and visible skin brightening.

This formula includes antioxidants glutathione and alpha-lipoic acid that help to protect the mitochondria, resulting in improved skin brightness and anti-aging benefits.

Can be used both day and night.

Key ingredients

Sodium ascorbyl phosphate: Prevents oxidation of debris in congested pores to clear and prevent breakouts.
Glyceryl ascorbate: Moisturizes to improve barrier function, provides sun protection, brightens skin.
Magnesium ascorbyl phosphate and tetrahexydecyl ascorbate: Provide anti-aging effects like collagen production enhancement and impede hyperpigmentation processes.
