Physical and chemical sunscreens differ in mechanisms, texture, and environmental impact. Physical options, containing zinc oxide or titanium dioxide, offer immediate, reef-safe protection but may leave a white cast. Chemical variants absorb UV rays, provide a lightweight feel, but risk irritating sensitive skin. Choice depends on skin type, activity, and ecological priorities. Regardless of formula, opt for broad-spectrum SPF 30+, reapply regularly, and prioritize water resistance for outdoor use. Combining both types in hybrid products balances coverage and comfort for diverse needs.
