How to Choose Sunscreen You Will Actually Use

Read the three essential claims

The AAD recommends looking for broad-spectrum protection, SPF 30 or higher and water resistance. Broad spectrum covers UVA and UVB. SPF is a tested measure principally related to UVB sunburn protection; it is not a multiplier for unlimited time outdoors. Water resistance is time-limited, so check whether the label states 40 or 80 minutes and follow its directions.

Regulatory labels vary by market, which matters to residents who buy products abroad. Read the package you hold rather than relying on an influencer's description. Check expiry and storage instructions; a sunscreen that has separated, changed colour or spent days in a hot car should not be assumed to deliver its labelled protection.

Match texture to use, not to identity

Skin colour, nationality and ethnicity do not diagnose whether skin is oily, dry or sensitive. Assess your own comfort and history. Acne-prone users may prefer non-comedogenic lotions or gels; dry areas may tolerate a cream. These labels are useful clues, not guarantees, and fragrance or other ingredients can still cause an individual reaction.

Tinted products can reduce visible white cast across many complexions. The AAD also notes that iron oxide in tinted sunscreen can add protection from visible light, relevant to dark marks and melasma. Select a shade and finish you can apply evenly rather than choosing a theoretically perfect product that you use too sparingly.

Choose for the day's setting

A short commute, a day on Lantau trails, harbour sightseeing and open-water swimming impose different demands. Outdoor exercise calls for water resistance plus shade, clothing, a hat and sunglasses. For office use, eye comfort and compatibility with make-up may determine whether the product is worn consistently.

Sticks can be helpful around the eyes but require repeated passes for coverage. Sprays are easy to under-apply and should be used exactly as labelled while avoiding inhalation. Lip products need their own SPF claim. Whatever the format, cover ears, neck and other exposed skin rather than only the centre of the face.

Treat sunscreen as part of a wider strategy

Sunscreen reduces ultraviolet exposure but does not make prolonged sun harmless. Reapply as directed, especially after swimming, sweating or towelling, and combine it with shade and protective clothing. Some exfoliants and prescription treatments require particular sun precautions, so follow professional and product guidance.

A changing mole, repeatedly crusting lesion, persistent rash or unexplained patch of pigment needs assessment rather than progressively higher SPF or bleaching products. Photograph change over time and seek medical advice.
