Lysine is an amino acid with significant hydrating and skin-stimulating effects in skin care.
Like all amino acids, lysine is naturally found in the skin at higher concentrations when you are younger. As you age, less of the healthy form of lysine, L-lysine, is available. Instead, a form of lysine known as N-epsilon(carboxymethyl)-lysine is available and accumulates in the collagen (Biochemistry). This contributes to the aged, hardened state of collagen, resulting in aged, dry, brittle skin.
Lysine is a Hydrating Amino Acid
Lysine is involved in the hydration of the skin, though applying lysine topically may also enhance collagen production (Journal of Peptide Science, 2012).
Lysine May Suppress Herpes and Psoriasis Outbreaks
Lysine appears to suppress the symptoms of herpes and psoriasis outbreaks. In one study, 45 patients with frequently recurring herpes infection were given 312–1,200 mg of lysine daily in single or multiple doses. The clinical results demonstrated a beneficial effect from supplementary lysine in accelerating recovery from herpes simplex infection and suppressing recurrence. The DNA codons characterizing herpes simplex DNA apparently specify production of viral capsids at the expense of host cell histones, resulting in less lesions. In another study, lysine use was found to decrease the amount and duration of psoriasis lesions.
Supplementing your skin with the amino acid lysine should provide your skin with more strength and resilience, as well as more supplies it needs to produce optimal levels of collagen and elastin and other structural proteins within your skin.
