Science
Mechanism of Action
This peptide operates by activating cellular autophagy and significantly increasing adiponectin expression, crucial for cellular integrity and stress response. It provides robust protection against UV-induced damage by counteracting adiponectin reduction, diminishing MMP-1 expression (a key collagen-degrading enzyme), and lowering the secretion of inflammatory cytokines such as IL-6 and IL-8. Additionally, it reduces oxidative stress and stimulates the endogenous synthesis of vital skin peptides like collagen, elastin, and keratin. The ingredient reinforces skin barrier function through the restoration of essential proteins including filaggrin, loricrin, and claudin-1, ultimately mitigating lines and wrinkles and enhancing skin firmness and tone.

Key findings
- 01 At a 0.01% topical concentration, pentasodium tetracarboxymethyl hexanoyl dipeptide-12 (PTHD-12) demonstrated a significant acceleration in the recovery rate of both skin redness and trans-epidermal water loss (TEWL) in UVB-irradiated skin, compared to a placebo. Ex vivo data also indicated its ability to prevent UVB-induced increases in the senescent cell marker p16INK4a, reduce UVB-induced TNF-α, and restore key skin barrier proteins (filaggrin, loricrin, claudin-1).
