DIPEPTIDE-39.

Insufficient Data / SKIN CONDITIONING

DIPEPTIDE-39 is a dipeptide, a short protein fragment composed of two amino acids. As a member of the peptide family, it may contribute to general skin health, though its specific biological activities require further investigation.

Science

Peptides, including dipeptides like DIPEPTIDE-39, are generally recognized for their potential to influence various skin functions. These mechanisms can involve supporting collagen synthesis, enhancing skin cell proliferation, or reducing inflammation. However, the exact mechanism of action for DIPEPTIDE-39 specifically has not been detailed in current research.

Stability

Dipeptides generally exhibit enhanced stability in sterile buffered solutions, ideally within a pH range of 5.0 to 6.0 when in solution. Adjustments to a physiological pH, typically around 7.0, are often considered for overall product stability and compatibility.

Conflicts

  • Direct acids
  • Retinoids
  • Strong antioxidants (e.g., Vitamin C)

Safety

CIR Status
Not reviewed
Sensitization risk Unknown

Specific safety assessments for DIPEPTIDE-39 by bodies such as CIR, SCCS, or FDA are not yet available. While the Cosmetic Ingredient Review (CIR) Expert Panel has broadly reviewed numerous proteins and peptides, DIPEPTIDE-39 has not been individually evaluated in these general reviews. FDA approval typically applies to therapeutic drugs rather than cosmetic ingredients.
