Formula IngredientPeptideAcetyl Tetrapeptide-2
INCI: Acetyl Tetrapeptide-2
Acetyl Tetrapeptide-2 is a four-amino-acid synthetic peptide created through acetylation of tetrapeptide-2. It mimics thymopoietin, a hormone produced by the thymus gland that declines with age. By compensating for the loss of thymic factors, it is claimed to stimulate the skin's immune defences and support skin regeneration. It is marketed under the trade name Thymulen 4.

Is Acetyl Tetrapeptide-2 safe? Key considerations
Can Acetyl Tetrapeptide-2 cause irritation?
Low RiskAcetyl tetrapeptide-2 is used at very low concentrations in cosmetic formulations and is well tolerated. No EU CosIng Annex II or III restrictions apply. Synthetic peptides are generally non-irritating.
Does Acetyl Tetrapeptide-2 increase sun sensitivity?
No RiskAcetyl tetrapeptide-2 does not increase photosensitivity. No special sun protection measures are required beyond a standard daily SPF routine.
Is Acetyl Tetrapeptide-2 safe during pregnancy?
CautionMANUAL REVIEW: No specific pregnancy safety data exists for topical acetyl tetrapeptide-2. As a synthetic peptide used at very low concentrations with minimal systemic absorption, it is unlikely to pose significant risk, but the absence of dedicated pregnancy safety studies warrants caution. Consult a healthcare provider if concerned.
