Homosalate is an organic UV filter that absorbs UVB radiation.
Octisalate (INCI: Ethylhexyl Salicylate) is an oil-soluble UVB-absorbing chemical sunscreen active. It is primarily used as a UVB filter and photostabilizer for avobenzone.
Homosalate: A suspected endocrine disruptor; the EU limits it to 7.34% in face products (2025), well below typical US concentrations.
Octisalate: Octisalate is FDA-approved at up to 5% and EU-permitted at up to 5%. It has a good safety record and low sensitization rate. The 2019 FDA absorption study detected systemic absorption above the 0.5 ng/mL threshold, warranting further study. This does not indicate known harm. It is a salicylate; those with aspirin sensitivity should note the structural relationship, though reactions are rare.
