Qué hace
Piel más firme, reducción de arrugas, cicatrización más rápida, posible crecimiento capilar.
Cómo funciona
El Tripeptide-1 actúa como un mensaje de texto que dice 'reparación necesaria': llama a los fibroblastos para reconstruir el colágeno y reparar el daño.
Se une a receptores en fibroblastos, queratinocitos y células de la papila dérmica, aumentando la expresión de factores de crecimiento.
Qué esperar
Mejora visible a las 4-8 semanas.
- Semanas 2-4: Mejora de la textura de la piel.
- Semanas 4-8: Reducción de líneas finas.
- Semanas 8-12: Piel más firme y resistente.
Bueno saber
- Realizar prueba de parche primero
- Evitar heridas abiertas
Manteniéndose seguro
- Mínimas; bien tolerado
Evitar si tienes:
- Antecedentes de cáncer de piel activo (riesgo teórico)
