Biochemical Mechanism & Pharmacology
Centella Asiatica & Madecassoside provides vital physiological lipids and humectants that reinforce the stratum corneum lipid matrix, preventing trans-epidermal water loss (TEWL) and buffering against irritation from Retinol without attenuating its therapeutic cellular benefits.
Apply the lower viscosity product first, or buffer by applying Centella Asiatica & Madecassoside prior to Retinol for sensitive skin (the sandwich method).
