We use both physical and chemical sunscreen agents! The main sunscreen agent we use is called UV Pearls, which combines the best of both physical and chemical sunscreens. Also known as Sunglasses for the Skin, UV Pearls encapsulate chemical sunscreen agents to prevent absorption into the skin.  No concern about skin irritation UV Pearls sit on the skin just like physical sunscreen, rather than getting absorbed into the skin, to absorb UV rays and dissipate them as heat, just like chemical sunscreen. And because of this encapsulation, chemical sunscreen does not come in contact with the skin, eliminating concerns about skin irritation.  Effective for longer Typically, chemical sunscreen degrades under the direct sunlight. Thanks to encapsulation, chemical sunscreen in the UV Pearls do not degrade as fast, making it effective for longer.  Superb texture without white cast Just like a chemical sunscreen, UV Pearls offer superb texture and spreadability with no white cast.
