Mechanism of Action
Pentapeptide-6, often presented as sh-Pentapeptide-6 Trifluoroacetate, functions as a biomessenger within the skin. It stimulates stratifin protein expression, which facilitates crucial communication between the epidermis and dermis. This optimized 'cross-talk' leads to enhanced extracellular matrix (ECM) turnover, balancing the degradation of aged collagen with the synthesis of new collagen types (I, III, Pro-collagen) and hyaluronic acid. Furthermore, it supports dermal reorganization, fortifying fibroblast strength and optimizing matrix contraction for improved skin architecture.

Key findings
- 01 Enhances epidermal stratifin expression, optimizing epidermal-dermal communication. Improves ECM turnover balance by promoting neo-collagen (Pro-collagen, Collagen I, Collagen III) and hyaluronic acid synthesis while aiding aged collagen degradation. Supports dermal reorganization, improving fibroblast strength and optimizing matrix contraction.

Formulation
Stability
For optimal stability and efficacy, products containing Pentapeptide-6 should ideally be housed in opaque, airless packaging. While generally compatible, it is advisable to avoid co-formulation or direct layering with highly acidic products (below pH 3.5) without careful consideration of routine separation.
Conflicts
- Highly acidic products (below pH 3.5)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed PENTAPEPTIDE-6 or sh-Pentapeptide-6 Trifluoroacetate. However, other pentapeptides, such as Myristoyl Pentapeptide-4, Palmitoyl Pentapeptide-4, and Pentapeptide-4, have been deemed safe for cosmetic use.
