Pentasodium Tetracarboxymethyl Palmitoyl Dipeptide-12

Pentasodium tetracarboxymethyl palmitoyl dipeptide-12 (PTPD-12) is a synthetic peptide — a short chain of amino acids designed to interact with skin cells. It functions as a skin conditioning agent and belongs to a category of ingredients that work by enhancing autophagy, which is your skin's natural cellular recycling mechanism.The ingredient is incorporated into creams and moisturisers at relatively low concentrations. Its primary mechanism involves stimulating the skin's ability to break down and clear cellular components, particularly those involved in pigmentation and inflammatory resp…

PTPD-12 works by activating autophagy — essentially, your skin's internal recycling system. This process allows cells to break down and clear damaged or unnecessary components, including melanosomes (the structures that contain pigment). By enhancing this natural cellular mechanism, the ingredient may help regulate melanin production and reduce the visible effects of hyperpigmentation.In inflammatory conditions, this same cellular recycling process may help reduce inflammatory markers and support skin barrier recovery. The ingredient essentially optimises how efficiently your skin cells man…

PTPD-12 is typically found in daily-use creams and moisturisers. Apply to cleansed skin morning and evening as part of your regular skincare routine. It works best as part of a consistent regimen — results are not immediate and typically become more noticeable after 4 weeks of regular use. It can be layered with other skincare products and does not require special timing or precautions.

PTPD-12 appears to be well-tolerated in the clinical studies conducted to date, with no serious adverse events reported. It is suitable for sensitive skin types, though as with any new ingredient, patch testing is advisable if you have a history of reactivity.
