What is Homosalate (15%)?
Homosalate is an organic compound commonly used as a UV filter in sunscreen products. It is produced by the esterification of salicylic acid with 3,3,5-trimethylcyclohexanol.
This ingredient is used in sunscreens to absorb UVB rays, which can cause skin damage and contribute to skin cancer. While it effectively helps in sun protection, there are concerns about its potential to penetrate the skin and act as a hormone disruptor due to its similarity to the body's natural hormones, though the evidence is mixed.
When seeing homosalate on a label, it's important to remember that its primary function is sun protection. If you have concerns over its absorption, you may want to consider discussing sunscreen options with a healthcare professional.
