Ingredients Details
Proline
Common Name(s): Pyrrolidine-2-carboxylic acid,l-proline
CAS Number: 147-85-3
DESCRIPTION
What It Does: Provides hydroxyproline precursor collagen support and osmoprotective nmf conditioning.
Why It's Used: The collagen imino acid โ proline and its hydroxylated form hydroxyproline comprise approximately 25% of all collagen amino acids, making l-proline the essential structural amino acid for topical collagen support.
How It Works: Hydroxylated by prolyl hydroxylase (requires vitamin c) to form hydroxyproline โ essential for collagen triple-helix stability. nmf osmoprotective function via pyrrolidine ring water interaction. proline-rich repeats in collagen provide gly-pro-hyp triple-helix structure.

SCIENTIFIC NOTE
Proline's prolyl hydroxylase conversion to hydroxyproline is completely vitamin c-dependent: the hydroxylase enzyme requires ascorbate as cofactor. this biochemical interdependence explains why vitamin c deficiency (scurvy) produces defective collagen โ hydroxyproline cannot form without vitamin c, and without hydroxyproline the collagen triple helix cannot maintain its structure at body temperature, causing tissue fragility.
