In this Riemann P20 Hyper-pigmentation Defence SPF 50+ PA++++ sunscreen lotion review, I find a solid performer which works well in harsher environments! Thanks again to Ian for the sample!
The Riemann P20 Hyper-pigmentation Defence SPF 50+ PA++++ sunscreen lotion is a chemical based sunscreen formulation using the active ingredients of Diethylamino Hydroxybenzoyl Hexyl Benzoate, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Methylene Bis-Benzotriazolyl Tetramethylbutylphenol, Ethylhexyl Triazone, Niacinamide, and Phenylethyl Resorcinol.
During testing, the Riemann P20 Hyper-pigmentation Defence blocked 99.84% of irradiated UVA, filtered 98.68% UVB, and blocked 99.67% UVI. Fantastic results given that this lotion is rather “liquidy” in consistency!
