Myristoyl Tripeptide-31 is a short tripeptide bound to myristic acid, a modification that improves its lipid affinity and penetration into the stratum corneum. In a formula it is presented as a signaling peptide, and the manufacturer links it to firmness and a more even texture. A caveat is in order: most of the data come from the supplier and independent evidence is scarce. The logic of signaling peptides is reasonable, but published clinical support for this specific peptide is limited. It is fairer to see it as a supporting anti-aging active with modest backing, not a guaranteed result. Topically the systemic contribution is negligible, so it can be used during pregnancy and breastfeeding. Tolerance is good: low irritation and allergy, suitable for sensitive skin. It has no meaningful comedogenic profile, so it fits any skin type within an anti-aging routine.
