Science
Mechanism of Action
The precise mechanism of DIPEPTIDE-19 in isolation is not extensively documented. However, when incorporated into fusion peptides like SH-OLIGOPEPTIDE-1 SH-POLYPEPTIDE-7 DIPEPTIDE-19, it is associated with a range of beneficial skin activities. These include promoting anti-wrinkle effects, enhancing skin firmness and lifting, supporting wound healing processes, and contributing to overall anti-aging cellular functions within the skin.

The Formula
Formulation
Stability
As with many peptides, DIPEPTIDE-19 is susceptible to various forms of degradation, including hydrolysis, oxidation, deamidation, and racemization, as well as physical instabilities like aggregation. Optimal stability is significantly influenced by the formulation's pH, temperature, exposure to light, and the presence of metal ions or peroxide contaminants. For related fusion peptides containing DIPEPTIDE-19, an optimal stability range is observed between pH 7.0 and 7.4, with a noted optimum around pH 7.2.
Synergies
- Other peptides in fusion complexes (e.g., SH-OLIGOPEPTIDE-1, SH-POLYPEPTIDE-7)
Conflicts
- Extreme pH environments (outside 7.0-7.4)
- High temperatures
- UV light exposure
- Presence of metal ions or peroxide contaminants
Safety
Safety Profile
DIPEPTIDE-19 has not undergone specific safety assessment by the Cosmetic Ingredient Review (CIR) panel or the SCCS. While a peptide referred to as 'Pep19' has achieved Generally Recognized as Safe (GRAS) status for oral consumption up to 3.8 grams per day for body fat reduction, this designation is not directly applicable to the topical cosmetic use of DIPEPTIDE-19 or its derivatives. Comprehensive topical safety data for DIPEPTIDE-19 specifically in cosmetics is currently unavailable.
