About this sunscreen

Peter Thomas Roth Max Sheer All Day Moisture Defense Lotion is an SPF 30 chemical sunscreen using an older-generation filter set including Homosalate, Ethylhexyl Methoxycinnamate, Benzophenone-3, and Avobenzone. It has a balanced finish with low white cast and a lightweight feel, but the formula commonly stings, so it is less ideal around the eyes. It works only okay under makeup and is generally low on pore-clogging. With moderate protection and a 55/100 score, it is a middling option held back by its dated filters.
