Science
Mechanism of Action
Caproyl Tyrosine functions as a specialized precursor that increases the concentration of L-tyrosine within melanocytes. By enhancing tyrosine bioavailability, it streamlines the melanogenesis pathway, allowing the skin to produce endogenous melanin more efficiently to provide a biological shield against UV-induced erythema.

Key findings
- 01 In vivo testing at a 3.0% concentration demonstrated that 60% of participants achieved a 25% reduction in UV-induced redness after 28 days of consistent application.
- 02 Research indicates that a 3-5% concentration provides the cellular equivalent of 10% pure tyrosine, significantly accelerating skin pigmentation when paired with light exposure.
Transparency
Dusting Analysis
To achieve measurable photoprotective and tanning acceleration benefits, concentrations of at least 3.0% are required. Many products include it at sub-1.0% levels for 'skin conditioning' claims without delivering the active biological benefits.
The Formula
Formulation
Stability
Highly versatile in emulsions and gels. While the potassium salt variant is highly water-soluble, the ingredient remains stable across a pH range of 3.0 to 7.5, though it performs most predictably near neutral pH.
