Science
Mechanism of Action
It reinforces the stratum corneum by forming a breathable, non-occlusive barrier that prevents transepidermal water loss (TEWL). At a molecular level, its high concentration of oleic acid (up to 80%) facilitates the penetration of bioactive polyphenols and tocopherols, which neutralize oxidative stress and suppress pro-inflammatory pathways like NF-kB, while also inhibiting tyrosinase to manage hyperpigmentation.

Key findings
- 01 Significantly enhanced skin moisture retention and antioxidant defense within an oil-in-water emulsion framework.
- 02 Stimulated the production of type I procollagen and effectively reduced TEWL in human skin cells.
- 03 Successfully inhibited melanin synthesis and tyrosinase activity without inducing cellular toxicity.

Dusting Analysis
Camellia seed oil is rarely used as a 'dusting' ingredient because it is functional even at very low concentrations (0.1% for collagen signaling). However, for noticeable emollient benefits and barrier repair, we look for concentrations above 1%.
