Mechanism

How it works

Melanostatine-5 works like a 'do not disturb' sign for melanocytes — it blocks the signal that tells them to produce pigment.

Decapeptide-12 is a tyrosinase inhibitor that acts as an alpha-MSH antagonist, reducing melanogenesis at the receptor level.

In depth

Full profile

What it does

Dark spots slowly fade and your skin tone looks more even.

How it works

Melanostatine-5 works like a 'do not disturb' sign for skin color cells. It blocks the message that tells them to make color.

It blocks the signal that tells skin cells to make color. This means they make less of the dark stuff.

What to expect

You can see your skin getting lighter in 6-8 weeks.

  • Weeks 2-4: Your skin tone starts to look a little more even.
  • Weeks 6-8: Dark spots begin to fade.
  • Weeks 10-12: Dark patches look much lighter.

Good to know

  • Test a small patch of skin first
  • Wear sunscreen every day
  • Start with a weaker amount

Staying safe

  • A little bit of skin irritation
  • Redness that goes away

Avoid if you have:

  • If you are pregnant or breastfeeding (we don't know enough yet)
  • If your skin reacts badly to these tiny proteins

Overview

Gradual lightening of dark spots, more even skin tone.

How it works

Melanostatine-5 works like a 'do not disturb' sign for melanocytes — it blocks the signal that tells them to produce pigment.

Competes with alpha-MSH for binding to MC1-R receptors on melanocytes, reducing tyrosinase activity.

Onset & timeline

Visible lightening at 6-8 weeks.

  • Weeks 2-4: Subtle evening of skin tone.
  • Weeks 6-8: Fading of dark spots.
  • Weeks 10-12: Significant hyperpigmentation reduction.

Getting the most from it

  • Patch test before use
  • Use sunscreen daily
  • Start with lower concentration

Qué hace

Las manchas oscuras se desvanecen lentamente y tu tono de piel se ve más uniforme.

Cómo funciona

Melanostatine-5 funciona como un letrero de 'no molestar' para las células del color de la piel. Bloquea el mensaje que les indica producir color.

Bloquea la señal que le dice a las células de la piel que produzcan color. Esto significa que producen menos de la sustancia oscura.

Qué esperar

Puedes notar que tu piel se aclara en 6-8 semanas.

  • Semanas 2-4: Tu tono de piel comienza a verse un poco más uniforme.
  • Semanas 6-8: Las manchas oscuras comienzan a desvanecerse.
  • Semanas 10-12: Las áreas oscuras se ven mucho más claras.

Bueno saber

  • Prueba una pequeña zona de la piel primero
  • Usa protector solar todos los días
  • Comienza con una concentración menor

Manteniéndose seguro

  • Un poco de irritación en la piel
  • Enrojecimiento que desaparece

Evitar si tienes:

  • Si estás embarazada o en periodo de lactancia (aún no sabemos suficiente)
  • Si tu piel reacciona mal a estos péptidos

Descripción general

Aclarado gradual de las manchas oscuras y tono de piel más uniforme.

Cómo funciona

Melanostatine-5 funciona como un letrero de 'no molestar' para los melanocitos: bloquea la señal que les indica producir pigmento.

Compite con el alpha-MSH por unirse a los receptores MC1-R en los melanocitos, reduciendo la actividad de la tirosinasa.

Inicio y cronología

Aclarado visible a las 6-8 semanas.

  • Semanas 2-4: Afinamiento sutil del tono de la piel.
  • Semanas 6-8: Desvanecimiento de las manchas oscuras.
  • Semanas 10-12: Reducción significativa de la hiperpigmentación.

Cómo aprovecharlo al máximo

  • Prueba de parche antes del uso
  • Usar protector solar a diario
  • Comenzar con menor concentración

Efectos secundarios comunes

  • Irritación leve
  • Enrojecimiento temporal

Mecanismo de acción

Decapeptide-12 es un inhibidor de la tirosinasa que actúa como antagonista del alpha-MSH, reduciendo la melanogénesis a nivel de receptor.
