Such is advice too often brushed aside, as are its ‘good for you’ counterparts ‘drink more water’ and ‘sleep 8 hours a day’. Common excuses: discomfort; visible white cast; taking ‘too much effort’. Mind you, UV radiation excuses no one. Shortwave UVB radiation causes sunburns and contributes to photo-ageing; long-wave UVA radiation is largely responsible for tanning (which, by the way, is an attempt to prevent DNA damage), long-term photo-ageing, and most grievously, impairment of basal layer skin cells, or ‘keratinocytes’, from which most skin cancers occur. Considering the array of sunscreens available today—from lightweight creams like Shiseido’s Sports BB Wetforce SPF 50++ to on-the-go cushions like Sulwhasoo’s Perfecting Cushion; and iterations of dry-touch chemical, hypersensitive physical and hybrid formulations—‘too much effort’ is too weak an excuse. Use sunscreen.
