Cosmetic peptides are short amino acid chains applied topically to the skin, regulated in the UK as cosmetics under the UK Cosmetic Products Regulation (not as medicines). The two most cited ingredients are GHK-Cu, a copper peptide with decades of in-vitro and human topical research, and Matrixyl 3000, a branded peptide blend by Sederma. PeptideClear compares UK serums and creams that use them, and links out to UK retailers such as Cult Beauty, LookFantastic and Boots.
Inside this category
What to look for on a UK peptide serum label
- · Named peptide ingredient at a meaningful position in the INCI list (top 8 ideally).
- · Disclosed active concentration where the brand publishes one (rare for serums, common for ampoules).
- · Compatible base (most peptides degrade in low pH; do not pair with vitamin C in the same step).
- · Air-tight packaging. Most peptides oxidise quickly in jars.
- · UK or EU manufacture for batch traceability.
