FAQ

Why is homosalate still allowed in sunscreen?
The FDA has not yet completed its review of homosalate safety. It was approved decades ago under older standards. The FDA's 2019 proposed rule requested more data, but homosalate remains legal while the review is pending.
Does homosalate break down in the sun?
Yes. Homosalate is photounstable and degrades under UV light, producing byproducts that are more toxic and more easily absorbed than the parent compound.
Is homosalate absorbed into the bloodstream?
Yes. A 2020 JAMA study found that homosalate was absorbed into the bloodstream at levels exceeding FDA safety thresholds after just one day of normal sunscreen use. The FDA has not yet determined whether this level of systemic absorption is safe.
Is homosalate an endocrine disruptor?
Cell studies have shown that homosalate disrupts estrogen, androgen, and progesterone signaling. A 2004 study in Toxicology demonstrated endocrine activity at concentrations relevant to cosmetic use, making it one of several chemical UV filters flagged for hormonal effects.
What is homosalate used for in sunscreen?
Homosalate absorbs UVB radiation and helps stabilize other UV filters like avobenzone. It is often a secondary ingredient rather than the primary UV filter, but its systemic absorption and endocrine disruption potential make it concerning regardless of its supporting role.
Does Numbrrrz use homosalate?
No. Numbrrrz contains no homosalate or any chemical UV filters. Our lip balms use organic coconut oil, organic jojoba oil, beeswax, and vitamin E — no sunscreen chemicals that could be absorbed into the bloodstream or disrupt hormones.
