Hair and nail growth stimulator
Definition: Tetra sodium di-succinyl L-cystine easily soluble in water, odorless, obtained by enzymatic synthesis.
Mode of action: The enzymatic grafting of succinic acid onto cystine, a keratin essential amino acid in the nails and hair, helps to increase cellular bioavailability of cystine while stimulating keratinocyte metabolism. KERASTIM S increases ATP synthesis, prevents hair from falling out and promotes nail growth
KERASTIM S at 0.25% increases by 35% the keratinocyte intracellular ATP.
USE LEVEL: 1-5%
