Homosalate is an organic (chemical) UV filter that primarily absorbs UVB radiation, commonly used at concentrations up to 10-15% to help protect skin from sunburn. It is often combined with other filters to provide broad-spectrum coverage and to stabilize the formulation.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation or stinging | Uncommon | Mild transient irritation, particularly on sensitive or compromised skin or near the eyes. |
| Allergic contact dermatitis | Rare | Sensitization to the salicylate filter reported in patch-testing studies. |
| Photoallergic or photocontact reaction | Rare | Reaction triggered by combined exposure to the ingredient and sunlight. |
| Potential endocrine activity | Very rare | In vitro and animal studies suggest possible weak hormonal effects; human relevance at topical use levels is not established. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
