The Ingredient Library

PDRN (Polydeoxyribonucleotide) is widely used in professional dermatology to accelerate tissue regeneration. Conventional PDRN is salmon-derived — MEDI SECTION NO.M uses an exclusively plant-derived Vegan PDRN that delivers equivalent regenerative benefits through a cruelty-free source. It activates the A2A adenosine receptor pathway to stimulate fibroblast activity, promote collagen synthesis, and accelerate cellular repair — clinically proven to improve skin texture, reduce redness, and restore vitality in post-procedure and compromised skin.

Bakuchiol is a plant-derived retinol alternative extracted from Psoralea corylifolia seeds. Published clinical studies show it delivers comparable improvements to retinol — reducing fine lines, improving firmness, and enhancing radiance — without the photosensitivity, dryness, or irritation that make retinol difficult for sensitive skin. Safe for daytime use and all seasons, making it the ideal anti-aging active for those who cannot tolerate retinol.

Centella Asiatica — widely known as Cica — is a medicinal herb with a centuries-long history in wound healing. Its four core actives work in synergy: Asiaticoside stimulates collagen synthesis and accelerates repair; Madecassoside delivers powerful anti-inflammatory action; Asiatic Acid reinforces the skin barrier structurally; and Madecassic Acid provides antioxidant protection. Together, they make Cica one of the most effective ingredients for sensitized, compromised, and post-procedure skin.

Peptides are short amino acid chains that act as biological signals, communicating directly with skin cells to stimulate collagen and elastin production. MEDI SECTION NO.M contains a clinically curated blend of 16 peptide types: Copper Tripeptide-1 for collagen stimulation and wound healing; Palmitoyl Pentapeptide-4 (Matrixyl) for measurable wrinkle reduction; Acetyl Hexapeptide-8 for expression line relaxation; and Palmitoyl Tetrapeptide-7 for anti-inflammatory support — delivering comprehensive anti-aging efficacy at the cellular level.
