Emollient Skin Barrier Support Hydrating Anti-inflammatory Antibacterial Sebum Regulating Keratinization Normalizer Anti-Acne Brightening (Pigmentation Reduction) Wound Healing Perfuming

Science

Mechanism of Action

Converted into linoleic acid within the skin, Ethyl Linoleate enhances the skin's lipid barrier, supports ceramide production, and significantly reduces transepidermal water loss, thus boosting hydration. It demonstrates antibacterial and anti-inflammatory effects, aids wound healing, and normalizes follicular keratinization and sebum secretion, making it particularly effective for acne-prone skin. Additionally, it brightens skin by inhibiting melanogenesis through specific signaling pathway downregulation.
