What the science says

Amino acids are building blocks of the skin's natural moisturizing factor and play a direct role in maintaining hydration and supporting collagen and elastin networks. Research and clinical studies show that topical application of amino acids, peptides and complementary hydrators such as hyaluronic acid and panthenol can increase skin moisture, improve elasticity and accelerate barrier repair. Ingredients like snail mucin and concentrated peptide complexes have supporting evidence from volunteer and laboratory studies for improved skin texture, wound repair and reduction in the appearance of fine lines when used consistently.

Amino acids contribute to the natural moisturizing factor and help attract and retain water in the epidermis.

Short peptides in serums and essences can signal collagen and elastin production, improving firmness and resilience over time.

Hyaluronic acid and panthenol synergize with amino acids to boost immediate hydration and long term barrier recovery.

Snail mucin formulations have clinical and user-study support for repairing the skin barrier and improving texture and hydration.

Omega-rich formulations support lipid barrier health, reducing transepidermal water loss and sensitization in dry or mature skin.

Most evidence comes from controlled clinical studies, in vivo trials and repeated consumer use studies showing measurable improvements in hydration and elasticity after weeks of use.
