Science & Benefits

A synthetic hydrocarbon used as a direct, acne-safe substitute for Squalane or Mineral Oil. It acts as a non-occlusive emollient that prevents transepidermal water loss (TEWL) without entering the pore. It is highly stable and resistant to oxidation. For acne users, it provides the 'slip' and 'glow' of an oil without the risk of lipid peroxidation that triggers inflammatory breakouts.
