Dermatologists Urge SPF50 in 8 Cases as SPF30 Remains Daily Minimum

Summary
Eight situations warrant SPF50 rather than SPF30, dermatologists said, including long outdoor exposure, reflective surfaces, high altitude, tropical locations, midday sun, photosensitising drugs, post-procedure skin, and pregnancy-related melasma risk.
SPF30 remains the baseline daily minimum, but experts said it should be broad-spectrum because the SPF number measures UVB protection only, while UVA also drives ageing, dark spots, and hyperpigmentation.
UV intensity rises about 10% to 12% for every 1,000 meters of elevation, and experts said water, sand, snow, concrete, clouds, and window glass can all increase or fail to block meaningful exposure.
SPF50 is the "sweet spot," one dermatologist said, with higher numbers offering only marginal extra benefit; proper use still matters, with reapplication every two hours and roughly two finger-lengths for face and neck.
