PENTASODIUM TETRACARBOXYMETHYL PALMITOYL DIPEPTIDE-12.

Valuable / SKIN CONDITIONING

Pentasodium Tetracarboxymethyl Palmitoyl Dipeptide-12 (PTPD-12) is an advanced autophagy-inducing peptide engineered to revitalize skin at a cellular level. It effectively addresses concerns ranging from compromised skin barrier and inflammation to hyperpigmentation, promoting overall skin health and resilience.

Science

Mechanism of Action

This specialized peptide, PTPD-12, functions by enhancing the natural autophagy process within skin cells. This cellular self-renewal mechanism actively reduces melanin content by stimulating autophagic flux, leading to the degradation of melanosomes in both melanocytes and keratinocytes. Furthermore, it improves sensitive skin conditions through multifaceted actions, including strengthening the epidermal barrier and mitigating inflammatory responses, evidenced by a significant reduction in inflammatory cytokines (IL-8, TNF-α) and PDE4 enzyme activity, concurrently increasing barrier marker protein expression.

Key findings

  1. 01 An emulsion containing 0.001% PTPD-12 (10 ppm) significantly improved skin barrier function, reducing Trans-Epidermal Water Loss (TEWL) by 9.73% and skin redness by 4.23% in volunteers with sensitive skin over 4 weeks.
  2. 02 A cream formulated with 0.01% PTPD-12 (100 ppm) demonstrated enhanced epidermal permeability barrier function after 4 weeks of application in healthy volunteers.
  3. 03 An 8-week split-face clinical trial on 21 participants with facial hyperpigmentation showed a significant reduction in melanin index from 216.93±45.57 at baseline to 194.69±38.70 at week 8, with no significant adverse effects.
  4. 04 Patients with mild-to-moderate atopic dermatitis experienced significant improvements in SCORAD score, skin hydration, TEWL, and pruritus at weeks 2 and 4 when using a PTPD-12-containing moisturizer.

Dusting Analysis

Not commonly dusted

PTPD-12 has reported clinical efficacy at specific, relatively low concentrations (0.001%-0.01%), suggesting its inclusion in formulations is typically at functional levels rather than for 'dusting' purposes.
