Humectant

Alanine

One of the most active amino acids in the skin's NMF — alanine moisturizes, protects against osmotic stress, and helps the skin maintain moisture balance even in dry climates or air-conditioned environments.

What is it?

Alanine (L-Alanine) — a proteinogenic α-amino acid, a significant component of the skin's NMF. It functions as an osmoprotectant — protecting cells from osmotic stress during dehydration or temperature fluctuations. Often found in amino acid NMF complexes. In INCI: Alanine or L-Alanine.

A component of amino acid NMF complexes in moisturizing toners, essences, and serums for dry and dehydrated skin.

Key Benefits

✦

Osmoprotection of skin cells

Protects cells from osmotic stress — fluctuations in salt and moisture concentration. Especially important in dry climates, air-conditioned environments, and after washing.

◈

NMF and moisture retention

A natural component of NMF attracts water from the environment and retains it in the stratum corneum, reducing TEWL.

✧

Synergy with other amino acids

Best expressed as part of a complete amino acid complex along with glycine, serine, proline, and lysine — reproducing the natural composition of the skin's NMF.

β-Alanine vs L-Alanine

L-Alanine (α-aminopropionic acid) — an amino acid found in proteins and NMF. β-Alanine — an isomer used in sports supplements. In cosmetics — always L-Alanine. These two molecules have different structures and properties.
