    InStyle – What’s the Difference Between Physical & Chemical Sunscreen? Here’s Everything You Need to Know


    Beauty editors worth their blowouts are often preaching the virtues of year-round SPF protection; nearly every anti-aging story we write recommends consistent application to prevent sun damage and aging. Most dermatologists recommend using a broad-spectrum formula with SPF 30+ on the daily—but you’ll still have the dilemma of whether to pick a physical or chemical sunscreen. If you’ve been left wondering what the difference is between the two, here’s your primer:

    Chemical Sunscreens
    These formulas require a little more patience, as they need to be applied 30 minutes prior to sun exposure to allow for absorption. Active ingredients like avobenzone, octinoxate and mexoryl then absorb the sun’s rays and neutralizes them. Think of it like this: “Chemical sunscreens acts like a sponge while the physical sunscreens acts like a wall,” says N.Y.C. dermatologistTabasum Mir, M.D. Since chemical varieties are available in a myriad of varieties (like aerosol sprays, lotions, and sticks), they’re usually easier to apply—but can sometime cause irritation for sensitive skin types. Since the sun can break down their effectiveness over time, it’s important to reapply throughout the day. Mir recommends La Roche Posay’s Anthelios ($35;amazon.com)
