What is Octisalate?
Octisalate is an organic compound commonly used in sunscreens as a UVB (ultraviolet B) filter. It helps stabilize other sunscreen ingredients and enhances the effectiveness of sun protection by absorbing UVB rays, which are primarily responsible for sunburn. Known for its ability to improve the water resistance and longevity of sunscreen formulations, octisalate is often used in combination with other UV filters for broad-spectrum sun protection.
Why do I have an intolerance?
Some individuals experience intolerance to octisalate, particularly those with sensitive or allergy-prone skin. Reactions can include itching, redness, or rash, especially with prolonged sun exposure after application. This sensitivity may stem from the way octisalate interacts with skin or other ingredients in the formulation.
What can I do about it?
If you are intolerant to octisalate, consider using mineral-based sunscreens containing zinc oxide or titanium dioxide, which provide broad-spectrum protection without the risk of irritation. Look for “octisalate-free” or “chemical-free” labels to identify suitable options. Mineral sunscreens are often recommended for those with sensitive skin as they offer physical sun blocking without the potential for allergic reactions.
