Uses In Skincare & Cosmetics

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Generally well tolerated, but oxidation byproducts may raise irritation risk for very sensitive skin. Product discoloration over time is usually cosmetic rather than a safety concern.

Is Tyrosine a Good Ingredient?

It rates Fair because it works primarily as a humectant, with limited clinical evidence for broader skin effects. It can also oxidize, and in rare cases may contribute to mild sensitivity.
