GABA at a glance

GABA stands for gamma-aminobutyric acid, a natural amino acid with the INCI Aminobutyric Acid. In the body it acts as a calming messenger, which has made it popular in skin care for products with a relaxing, smoothing message. The cosmetic grade is a white or cream powder from Japan with a neutral, faint odor. It dissolves in water to a clear solution, has a pH of 6.5 to 8.0 and is used at low levels, usually 0.05 to 0.3%, up to 1% depending on the product.

The relaxing amino acid

Most amino acids in skin care are building blocks of proteins or parts of the natural moisturizing factor. GABA is different. It is not built into proteins, and it is best known for its calming role in the body. In cosmetics this idea translates into products that help skin look relaxed and smooth. Expression lines on the forehead and around the eyes are a key target, which is why GABA often appears in products with a soft focus or expression line message.

What it does

The supplier lists several benefits. GABA helps fine lines and wrinkles look less visible thanks to its relaxing character. It supports a smoother, more even skin texture. It helps skin feel calmer and softer and look less irritated. It supports hydration and helps prevent dryness, so skin looks smoother and more elastic. It also adds antioxidant protection against daily environmental stress. On the pack, keep claims visual and sensory.

Dosing

Most products use 0.05 to 0.3%. Intensive serums and eye products can go up to 1%. Because the doses are low, a premix in water makes weighing easier: dissolve 1 part of GABA in 9 parts of water and dose the solution at ten times the target level.

How to formulate

Add the powder or its premix to the water phase. It dissolves to a clear solution, so it suits clear serums and toners as well as creams. Keep the finished product at about pH 5.5 to 7. GABA is often combined with other expression line actives, such as the peptide acetyl hexapeptide-8, and with humectants such as trehalose.

Dissolve GABA and trehalose in the water, disperse the cellulose, add glycerin, propanediol and panthenol, then the preservative, and adjust to about pH 6.

Labeling and story

On the ingredient list it appears as Aminobutyric Acid.

Testing claims

Expression line claims are best supported with skin replicas or 3D imaging of the crow's feet area before and after four to eight weeks, together with self assessment.

Why a low dose

GABA works as a signal rather than a bulk ingredient, so small amounts are enough. At 0.05 to 0.3% it has no effect on texture, color or odor, and it can be added to an existing base without reformulating. This also keeps the cost per unit low.

Storage

Store in a dry, cool room in a tightly closed container, protected from light. A certificate of analysis comes with every lot.
