Frequently asked questions

Where can Meradimate be used?

In this data it is approved only in the US, with a 5% cap. It is not approved in the EU, Japan, or Korea, so it is essentially absent from sunscreens formulated for those markets.

What part of the UV range does it cover?

It absorbs in UVA2, the shorter-wavelength UVA range. It does not provide UVB coverage, so it is paired with UVB and ideally UVA1 filters for a balanced sunscreen.

Why is Meradimate rarely seen on labels?

It is an older, US-only filter with weak relative absorbance compared to newer options. Available data shows it in essentially zero current products in this catalog.

Is it photostable?

Yes, available data lists Meradimate as photostable on its own, but its limited spectrum and US-only approval keep it from being a common choice for modern formulas.
