AMINO ACIDS

AMINO ACIDS

Amino acids are the building blocks of both peptides and proteins, and each has a specific role in skin care. Amino acids maintain skin’s hydration, texture, resilience, and an overall supple, healthy appearance.

Peptides, also known as collagen peptides, are proteins found in the body spontaneously, which serve to increase the amount of collagen in the body that decreases with aging.

Amino acids are naturally present in skin, as part of what’s called our natural moisturizing factors (NMFs). Within the skin’s uppermost layers, amino acids work as conductors, orchestrating an incredibly complex “concert” that allows our skin to thrive and to stay hydrated.

• Arginine plays a role in repairing visible skin damage.
• Histidine has antioxidant ability and can soothe skin.
• Methionine neutralizes damaging substances before they can harm the skin.
• Lysine helps visibly firm skin’s surface by reinforcing its supportive elements.
• Proline, leucine, and glycine diminish the look of fine lines and wrinkles.
