BEMT (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine): This is a highly effective and stable organic sunscreen filter. The product description does not mention it causing irritation or clogging. Sunscreen filters can sometimes cause sensitivity in some individuals, but BEMT is generally well-tolerated.
