Have you ever tried to write a resume for a field you have no experience in? Let me tell you, it’s much harder than it seems. Imagine having years of experience in a field, and having to try to tailor those experiences to another unrelated field. It sounds like B.S’ing a high school essay. It almost even feels like writing a sunscreen post, the only difference is that I at least have some decent results I can actually write about in these. Such is the life of a peasant though, I digress.
The La Roche-Posay Anthelios UVMune 400 SPF 50 sunscreen lotion is a chemical sunscreen formula which contains Ethylhexyl Salicylate, Ethylhexyl Triazone, Bis-ethylhexyloxyphenol Methoxyphenyl Triazine, Drometrizole Trisiloxane, Butyl Methoxydibenzoylmethane, Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate, Diethylamino Hydroxybenzoyl Hexyl Benzoate, and Terephthalylidene Dicamphor Sulfonic Acid.
The La Roche-Posay Anthelios UVMune 400 reduced 98.79% of irradiated UVA, 98.04% UVB, and 98.73% of total UVI. Great UV filtering performance!
