Doctors in Singapore are emphasizing the importance of consistent sunscreen application, particularly on often-neglected areas like eyelids, ears, neck, chest, and the backs of hands, which are vulnerable to cumulative sun damage. In Singapore, UV levels frequently reach "very high" and "extreme" ranges, exacerbated by modern lifestyles that increase outdoor exposure. This consistent, low-dose UV exposure contributes to pigmentation, wrinkles, collagen breakdown, and DNA damage linked to skin cancers, even without visible sunburn. Experts recommend systematic daily application, reapplication every two hours (though this is often overlooked, especially by athletes), and supplementing sunscreen with protective measures like hats and UPF clothing. While specialized sunscreens exist for specific areas, a properly applied regular SPF50 sunscreen is generally sufficient, though spray formulations are discouraged due to uneven application.
