sunscreen is one of the most common methods of protecting your skin from the sun's harsh rays, while getting a gorgeous glow.
As per leading Indian herbal beauty expert Shahnaz Husain, "Exposure to the sun leads to sun tan, sun burn and many other effects. Apart from tanning, the skin is exposed to harmful ultraviolet rays of the sun, which has several long-term effects, like early formation of lines and wrinkles on the skin. Sun-exposure can also lead to dark spots or patches."
She says that the skin must be protected with a broad-spectrum sunscreen, which provides protection from both UV-A and UV-B rays of the sun.
What are UV rays?
Husain notes, "The sun gives off ultraviolet rays. We divide them into categories based on the wavelength. There are UV-A, UV- B and UV-C rays. Of these, UVC rays are almost completely absorbed by the ozone layer and do not affect the skin. UVB affects the outer layer of skin and is mainly responsible for sunburns. It is the most intense between the hours of 10:00 am and 2:00 pm when the sunlight is brightest. UVA rays were once thought to have a minor effect on skin damage, but now studies are showing that UVA is a major contributor to skin damage."
She added, "Sun exposure can also cause loss of moisture from the skin. However, most sunscreens have built-in moisturisers. So, it is not necessary to apply both moisturiser and sunscreen, unless the skin is very dry."
So what is the answer? Husain says, "At the moment, physical protection is the answer. This can be done by applying a broad-spectrum sunscreen. A sunscreen is a product which forms a protective cover between the skin and the sun's rays, while a broad-spectrum sunscreen is one which provides protection from both UV-A and UV-B rays of the sun. Both UVA and UVB radiation can cause skin damage, including premature ageing signs. There are many other effects. As already mentioned, sunscreens help to protect the skin from UV rays."
