FAQs | SunSense Taiwan


No matter what the SPF is, you should reapply sunscreen every two hours. This is because sweating, swimming, rubbing of clothes, towelling dry, exercise and touching our skin will all remove sunscreen. If we don’t reapply we can end up with unprotected areas, and get burnt.

Sunlight is composed of different components including Ultra Violet (UV) radiation. UV radiation can be considered dangerous as it cannot be seen or felt.^

UVA rays are mostly responsible for the signs of premature ageing because they are able to penetrate deeper into the surface of the skin. UVA radiation which is responsible for photoageing is capable of penetrate into the skin's deeper layers.* When you think of wrinkles, think UVA rays.*

UVB radiation which causes sunburn is capable of penetrating only the skin's superficial layers.* Fortunately, the atmosphere or ozone absorbs most of the UVB radiation.* When you think UVB rays, think sunburn.*

All SunSense sunscreens offer protection from both UVA and UVB radiation.
