What should you know about mineral based sun screen?

Mineral filters form a protective layer that reflects, scatters, and absorbs parts of ultraviolet radiation. They can be useful for daily exposed skin and for people who prefer to avoid certain chemical filters. A product may leave a visible cast, especially on deeper skin tones, although tinted and finely dispersed formulas may blend more easily. Sunscreen does not block every exposure or replace shade and protective clothing.

Apply a generous, even layer to exposed skin before going outdoors, including often-missed areas such as ears, hairline, neck, and backs of hands. Reapply after swimming, sweating, towelling, or prolonged outdoor time, following the label. Add shade, a hat, sunglasses, and clothing when possible. Patch-test a new product if your skin reacts easily, and choose a formula suited to your skin and activity. See Mineral Sunscreen for more detail.

Stop using a product and seek advice for persistent burning, swelling, blistering, or a spreading rash. Arrange a skin examination for a sore that does not heal, a spot that changes in colour or shape, or a new lesion that repeatedly bleeds. Sun protection supports prevention but does not diagnose or treat an existing skin cancer.

Ask which filter and formulation suit your skin, whether a tinted option may help with visible residue, and how to protect a scar, melasma, or photosensitive condition. Ask how often to reapply during your usual work, exercise, or beach routine.
