Sunscreen
A topical product that shields skin from ultraviolet (UV) radiation by absorbing, reflecting, or scattering UV rays.
Sunscreen is a topical formulation designed to reduce the amount of ultraviolet radiation that reaches your skin. It falls into two broad categories: chemical (organic) filters, which absorb UV energy and convert it into small amounts of heat, and mineral (inorganic) filters like zinc oxide and titanium dioxide, which sit on the skin's surface and mainly absorb UV (while also scattering or reflecting a smaller amount). Many modern formulations blend both types for broader spectrum coverage.
In practice, sunscreen is the final step in a morning skincare routine, applied after moisturiser and before makeup. The standard recommendation is roughly half a teaspoon for the face and neck. SPF ratings indicate the level of UVB filtration, while broad-spectrum labelling means the product also addresses UVA rays. In Australia, sunscreens are regulated as therapeutic goods by the TGA, so the SPF claims on your bottle have been independently verified. Reapplication every two hours during sun exposure, and after swimming or sweating, is essential for the product to perform as labelled.
Why does this matter to you as a shopper? UV exposure is the single largest environmental contributor to premature skin ageing, including fine lines, uneven tone, and loss of firmness. Sunscreen pairs well with antioxidant serums like vitamin C, which can offer complementary support against environmental stressors. If you find certain chemical filters irritating, mineral options tend to be gentler and can suit sensitive skin nicely.
Honest caveats: no sunscreen blocks 100% of UV radiation, and SPF only measures UVB filtration, not the full picture. A high SPF is not a free pass for extended, unprotected sun exposure. Sunscreen works best as part of a broader approach that includes hats, shade, and sun-smart timing. If you have a skin condition that makes you particularly reactive to sunlight or to certain filter ingredients, it is worth speaking to a dermatologist or skincare professional to find a formulation that supports your skin comfortably.
