Even if time stood still, the sun, by itself, could cause aging of the skin.
Exposure to the sun leads to suntan, sunburn, and many other effects. The skin is exposed to harmful ultraviolet rays of the sun, which has several long-term effects, like the early formation of lines and wrinkles.
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? 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 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 damage.
Sun exposure can also cause a loss of moisture from the skin. However, most sunscreens have built-in moisturizers. So, it is not necessary to apply both moisturiser and sunscreen, unless the skin is dehydrated.

So what is the answer? At the moment, physical protection is the answer. This can be done by applying broad-spectrum sunscreen. 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 damage, including premature ageing signs.
The SPF also must be considered before selecting the sunscreen. For most skins, SPF of 20 to 25 should be adequate. However, sun-sensitive skins that are prone to allergic reactions, redness, or dark spots and patches, should opt for a higher SPF of 40 and above. Your sunscreen should be according to skin type. Sunscreens and sun-blocks are available in both lotion and cream forms. If the skin is very dry, you may apply the sunscreen, wait for a few minutes and then apply a moisturizer, or apply a sunscreen cream. A normal to oily skin may need an oil-free sunscreen gel so that the pores do not get clogged and lead to acne.

You may ask, “What is the difference between sunblocks and Sunscreens?” Sun-block contains ingredients that act as a barrier between your skin and UV rays by reflecting them, while a Sunscreen absorbs the UV rays before they can damage the inner layer. A sun-block product may leave a whitish residue or effect, as one sees on sportspeople and athletes.
As already mentioned, sun exposure can cause a loss of moisture. However, most sunscreens have built-in moisturizers. It is essential to apply sunscreen, not only on the face but also on all exposed areas. The back of the neck and arms are extremely vulnerable to sun damage too. The sunscreen should be applied about 20 minutes before sun exposure. If you happen to be in the sun for more than an hour, you should re-apply with the sunscreen. Try to avoid sun exposure between noon and 3 p.m. Remember to apply sunscreen while swimming, holidaying by the sea or in the hills. Reflective surfaces, like water and snow, actually increase the effects of UV rays.
Remember, that even if Time stood still, the sun, by itself, can cause visible aging signs.
