Choosing a Sunscreen

The active ingredients in sunscreen fall into two categories: physical filters and chemical filters. Some sunscreens consist of both physical and chemical filters, while others use just one type of filter.

Physical filters include the old classics, titanium dioxide and zinc oxide. They work by literally forming a physical barrier that reflects light away from your skin. Physical filters are very gentle and kind to sensitive skin, but tend to be a little heavier. While physical sunblocks are sun-stable (meaning they don’t degrade when exposed to the sun’s rays), it’s still a good idea to re-apply; swimming and sweating can make the sunscreen wear off your skin.

Chemical filters absorb and diffuse sunlight. Wait 15 minutes after applying to give the filter time to protect your skin. Chemical filters aren’t as gentle as physical filters, but they’re quite a bit lighter on the skin and less likely to clog your pores. Unlike physical filters, most chemical filters are not sun-stable and must be reapplied throughout the day. However, chemical filters can protect your skin from a wider variety of light wavelengths than their physical counterparts.
