Medik8 Liquid Peptides Advanced MP ingredients: is it worth it?
This is a genuinely high-tech peptide bomb with strong anti-aging potential, but it’s more of a sophisticated support serum than a complete all-round treatment.

The efficacy score is driven by the very high density and diversity of well-studied signaling peptides (including Matrixyl-type peptides, copper peptides and expression-line-targeting neuropeptide analogues) sitting high in the INCI within a hydrating, silicone-gel base; however, the formula lacks gold-standard actives like retinoids or a dedicated, proven brightening system and instead focuses almost entirely on collagen, texture and fine-line pathways, so its impressive clinical marketing claims remain largely peptide-dependent rather than backed by multiple cornerstone actives.
