Tetrapeptide-7 ●
TL;DR. This ingredient is used as a skin-conditioning signal peptide, typically included in serums, moisturizers, and eye products to support a smoother-looking, calmer-looking skin surface.
What does Tetrapeptide-7 do in a cosmetic formula?
This ingredient is used as a skin-conditioning signal peptide, typically included in serums, moisturizers, and eye products to support a smoother-looking, calmer-looking skin surface.
Is Tetrapeptide-7 clean?
From a clean-beauty perspective, it is generally low-irritation and not a common allergen, with little restricted-list friction. The main caveat is that commercial versions are usually synthetically made, so standards vary by certifier and supplier documentation.
Is Tetrapeptide-7 sustainable?
This material is usually made through peptide synthesis rather than direct agricultural extraction. It is expected to break down into amino-acid fragments, but its sustainability profile depends on solvent use, purification steps, and manufacturing controls.
Is Tetrapeptide-7 COSMOS-approved?
It is not a straightforward COSMOS-organic fit because it is typically a synthetic specialty active, and acceptance depends on the exact manufacturing route and supporting documentation. Its Green Chemistry profile is mixed, with a biodegradable molecular backbone but relatively resource-intensive synthesis and purification.
How does Tetrapeptide-7 work chemically?
The molecule is a small, water-soluble chain of four amino-acid residues designed for low-level signaling activity in skin-care formulas. It is typically used at very low active concentrations in aqueous systems, and formulators usually protect it from extreme pH, high heat, and incompatible preservatives or charged polymers.
