Science
Mechanism of Action
Pigskin extract, primarily composed of porcine collagen types I and III, mirrors the collagen types abundant in human skin. It supplies vital amino acids such as proline and glycine, fundamental for the body's natural collagen synthesis, thereby aiding in maintaining skin integrity. Topically, its action is primarily as a humectant, drawing and retaining moisture, and forming a protective film to enhance skin hydration and reduce dryness. In its hydrolyzed peptide form, it is observed to penetrate the skin more effectively, potentially offering antioxidant and anti-aging benefits, and has shown a capacity to inhibit tyrosinase activity and melanin production.

Key findings
- 01 Significantly inhibited melanogenesis in B16F10 melanoma cells and reduced pigment deposition in zebrafish, suggesting anti-pigmentation effects.
- 02 Provided significant hydration and formed a sticky moisture barrier, although it did not visibly reduce fine lines.
- 03 Showed a significant reduction in pigmented patches and redness over 3 months.

Dusting Analysis
While larger collagen molecules may have limited skin permeation and some forms could be seen as primarily film-forming, the research highlights the efficacy of *hydrolyzed* pigskin collagen peptides. These smaller fragments demonstrate specific biological activities, such as anti-pigmentation, that go beyond superficial 'dusting' effects, making it a functional ingredient at appropriate concentrations.
The Formula
Formulation
Stability
This water-soluble ingredient performs optimally in cosmetic formulations within a slightly acidic to neutral pH range (4.0-7.5). Maintaining this pH range is crucial for stability and to prevent denaturation, particularly for protein-based components.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed hydrolyzed collagen, a common form of pigskin extract, as safe for cosmetic applications. Regulatory frameworks, such as EU CosIng, advise adherence to animal by-product regulations. However, general safety concerns for well-processed gelatin/hydrolyzed collagen from animal origins are considered very low. It is recognized in Canada as a skin-conditioning agent for topical use.
