Signal peptides in skin care
Peptides in skincare are often divided into signal peptides (Matrixyl), carrier peptides (GHK-Cu) and neurotransmitter peptides. They are studied for collagen, elasticity and skin barrier.
How they are combined with classic active ingredients
Peptides are often used in conjunction with niacinamide, hyaluronic acid, and sunscreen. They are not a replacement for retinoids, but they offer a gentler avenue of research.
The list
The list is editorial and is based on how often the substances appear in research – not on proven efficacy or safety in humans.
The difference between potential and evidence
Always review safety, study size, control groups, and whether the results have been replicated. Be especially wary of claims that promise quick or guaranteed effects.
