Mechanism of Action
TETRACARBOXYMETHYL PALMITOYL DIPEPTIDE-12 (PTPD-12) functions as an autophagy-inducing peptide, promoting cellular autophagic flux. This process is instrumental in facilitating the degradation of melanosomes within melanocytes and keratinocytes, leading to a measurable decrease in melanin content and subsequently mitigating hyperpigmentation. For sensitive skin, it reinforces barrier function and modulates inflammatory responses by reducing pro-inflammatory cytokines, specifically IL-8 and TNF-α, and regulating PDE4 enzyme activity. Its autophagy-activating properties also benefit acne-prone skin by reducing closed comedones and surface lipids, and in atopic dermatitis, it aids in inflammation management and contributes to skin barrier restoration.
