Peptid4® Light MB offers a smarter approach to skin tone care. This next-generation synthetic tetrapeptide helps control pigmentation at the biological source of hyperpigmentation.

Unlike conventional brightening ingredients, Peptid4® Light MB targets the MC1R receptor. This helps modulate melanogenesis upstream, before melanin formation begins. The ingredient reduces melanin by up to 66%, with no rebound effect.

This makes Peptid4® Light MB a precise option for brands developing products for tone uniformity, sensitive skin, and intelligent skin longevity.
