Sunscreen is important, especially in Summer.
Wearing sunscreen is one of the best & easiest — ways to protect your skin's appearance and health at any age. Used regularly, sunscreen helps prevent sunburn, skin cancer and premature aging. To help make sunscreen a part of your daily routine, dermatologist 張瑋庭醫師 addresses common concerns.
What sunscreen should I buy?
For day-to-day use, pick a sunscreen with an SPF of at least 30. If you spend time outdoors, choose a product with SPF 60 or greater. In reality, most people do not use as much sunscreen as they should, and this higher SPF helps compensate for the reduced application.Are mineral sunscreens better?
Sunscreens are often grouped into two categories: chemical and mineral. Chemical sunscreens use ingredients like avobenzone, octisalate, octocrylene, homosalate and others. Mineral sunscreens use either zinc oxide or titanium dioxide. Both chemical and mineral sunscreens work similarly (by absorbing UV light and transforming that energy into negligible amounts of heat). Mineral sunscreens also reflect a small amount of UV light.For some, chemical sunscreens can sting. If you have sensitive skin or frequently react to products, mineral sunscreen might be a better choice. The downside of mineral sunscreens is that they often leave a noticeable white cast, particularly on skin of color.
