Science
Mechanism of Action
This ingredient actively attracts and retains moisture, thereby augmenting skin hydration levels. It establishes a protective, non-occlusive barrier on the skin's surface, which aids in preventing dehydration. Beyond surface-level action, Hydrolyzed Elastin is believed to support cellular regeneration and replenish cell synthesis, contributing to improved skin elasticity and firmness. It can also stimulate dermal fibroblasts, encouraging the production of vital extracellular matrix components like collagen and native elastin, which helps to mitigate the appearance of fine lines and wrinkles.

Dusting Analysis
No data indicates that Hydrolyzed Elastin is commonly used in 'dusting' concentrations or that specific dusting thresholds are relevant for this ingredient.
The Formula
Formulation
Stability
The optimal pH range for Hydrolyzed Elastin is typically between 4.5 and 5.5. However, its hydrolyzed nature allows for compatibility across a wider pH spectrum in personal care formulations. Water-soluble elastin powder formulations have demonstrated robust physical and chemical stability, including stable pH, viscosity, and color, over a 12-week period at various temperatures.
Conflicts
- Improper formulation or extended exposure to light and air can sometimes lead to discoloration, though this may not impact its efficacy.
- May increase the perceived stickiness of cosmetic applications, potentially affecting the product's spreadability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded Hydrolyzed Elastin is safe for use in cosmetic practices at concentrations up to 25%. The U.S. Food and Drug Administration (FDA) confirms that bovine-derived hydrolyzed elastin, when highly processed for cosmetic use, does not pose a risk of bovine spongiform encephalopathy (BSE) infection. A Human Repeat Insult Patch Test (HRIPT) involving 52 subjects, utilizing 25% w/v Hydrolyzed Elastin (MW = 3000 Da) in corn oil, revealed no dermal irritation or sensitization. However, rare individual allergic reactions are possible in particularly sensitive individuals. No specific SCCS opinion was found.
