Sunscreen protects us from the ultraviolet rays that come from the sun. Uv rays are a part of the natural electromagnetic spectrum that consists of UV rays, visible rays and infrared rays. There are three types of UV rays, UV- A, B and C. Most of the rays get blocked in the Earth’s atmosphere, but some of them reach up to our skin. It causes various problems like skin darkening prematurely, ageing, wrinkles and sunspots. But when people think about sunscreen, most of us tend to focus on preventing skin tanning or skin darkening. Whitening sunscreen can be a much better alternative to regular sunscreen. Because it not only protects the skin but also takes care of the nourishment of the skin as well.
Why do we need sunscreen at all?
Vitamin D is quite necessary for the human body as we can not produce it internally. It is quite essential for our health, but prolonged exposure to the sun can damage our skin. But it does not just stop there; it can also cause various problems like sunburn, tanning, darkening, wrinkles etc. Excessive exposure to the sun can even lead to premature ageing and skin cancer, as well. It is why it is recommended to use sunscreen to reduce the damage done by the UV rays to your skin.
