In this Altruist Dermatologist SPF 50 sunscreen lotion review, I test a fantastic formulation which I personally used in a warm, humid, environment. Thanks again to Stephanie from London for providing me this sunscreen to test!
The Altruist Dermatologist SPF 50 sunscreen lotion is a hybrid sunscreen formulation using the active ingredients of Butyl Methoxydibenzoylmethane, Ethylhexyl Salicylate, Octocrylene, Titanium Dioxide (Nano), Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Phenylbenzimidazole Sulfonic Acid, Ethylhexyl Triazone, and Titanium Dioxide.
The results from testing show the Altruist Dermatologist SPF 50 sunscreen lotion is very good at blocking UVA by blocking 99.97%, filtering UVB by 99.19%, and reducing total UVI by 99.91%. This is very high performing sunscreen lotion!

Testing notes:
I actually brought this sunscreen on my recent trip to Vietnam where my entire family used it in very hot and humid weather. We used it during beach activities (swimming, playing around in the sand), as well as just walking around seeing the sights. We didn’t get burned despite the incredibly powerful sun (and did not really tan too much either). I would say the real world results match the sunscreen testing results well enough for me.
