sunscreen is a substance that helps prevent skin cancer and, more importantly, sunburn. Sunscreens are commercially produced in a variety of forms, including sticks, sprays, gels, foams (e. g., expanded foams or whipped lotions), emulsions, gels, sprays, powders, and other topical formulations. Generally speaking, there are two kinds of sunscreen: chemical sunscreen and physical sunscreen. What is the difference between the two?
chemical sunscreens do not stick to the skin or deflect sunlight. Instead, they contain potent compounds that consume UV light before it is absorbed by the skin. Some of the filters in chemical sunscreens are oxybenzone, avobenzone, and octyl salicylate. This chemical sunscreen takes 20 to 30 minutes to be absorbed by the skin. Physical sunscreens, on the other hand, work by creating a physical barrier between the skin to protect it from the sun. This sunscreen helps to reflect UV radiation on the skin. Physical sunscreen provides instant protection, and you don't need to wait for it to fully function. Neither mineral sunscreen nor chemical sunscreen is perfect, so people can use both sunscreens at the same time without worrying about whether they are harmful to the skin.
Whether physical or chemical, sunscreen is important to protect our skin from harmful ultraviolet radiation that can cause skin cancer. Regular use of sunscreen also helps prevent sunburn and premature aging, helping to protect the appearance of skin at any age. Long-term or short-term life outside it is very important to apply sunscreen to cover exposed skin.
