Tolerability, children and vitamin D, with the clinical questions handed over
Whether mineral formulations are genuinely better tolerated, what the chemistry says about blocked pores, what the guidance is for children, why the vitamin D argument is answered by dietary guidance, and the umbrella safety claim taken apart.
Is mineral sunscreen genuinely better tolerated by sensitive skin?
The perception has a plausible mechanism and thinner evidence than the perception implies. Separating irritation, allergy and discomfort explains most of it.
Mineral sunscreen and skin prone to blocked pores: what the chemistry suggests
Comedogenicity is a property of a formulation rather than of a filter class, and the tests behind the word are weaker than the confidence attached to it.
Mineral sunscreen for babies and children: what the guidance says and where chemistry stops
The preference for mineral filters on children has a defensible basis. The guidance that matters is about shade, clothing and age, and it comes from the NHS.
Vitamin D and sunscreen: a nutrition and public health question, not a reason to stop protecting skin
The vitamin D argument is used to justify unprotected sun exposure. In the UK it is answered by dietary guidance, and the guidance is not about sunscreen.
Is mineral sunscreen safer? The umbrella claim, taken apart
The claim that holds the category together, assembled from its parts and assessed against what each part actually establishes.
