Here are a few reasons on how sunscreen help protect your skin.
Protection from UV rays
Sunscreens contains mineral zinc oxide which provides protection from harmful sun UV rays, it acts a shield against UVB and UVA rays. UVB rays are responsible for causing sunburn whereas UVA rays play a major role in premature ageing.
Reduces the chances of skin cancer
Excess sun exposure can irritate the skin and can cause the skin cells to die. Application of sunscreen daily protects the skin and with the continuous use of the sunscreen one can feel the change.
Tanning refers to the darkening of the skin tone when it is exposed to the UV rays, UV rays increases melanin production which causes tanning.The shield provided by the sunscreen protects from skin discoloration and enhances the health of the skin.
As already mentioned, sunrays can lead to sunburn and formation of dead skin cells might cause skin cancer. Sunscreens protect the skin from direct UV ray’s exposure. Regular use of the sunscreen can easily prevent sunburn.
Protects from chlorinated/salty water
Who doesn’t love swimming in summers? But the salty/chlorinated water can cause skin tan and can harm the skin in various ways; it can lead to dark patches, acne and spots. Application of sunscreen before direct contact with salted or chlorinated water can prevent such effects. It acts as a shield which doesn’t allow the salts of the water to affect the skin.
Prevents premature aging
UV light damages collagen and elastic tissues in the skin, so it becomes fragile and the face shape is highly affected causing sagging. Sun rays causes wrinkles, pigmentation, sunspots and reduced skin elasticity. Sunscreen helps in protecting the skin from any such causes.
TIPS ON APPLICATION OF SUNSCREEN
It must be applied at least half an hour before having any contact with the UV rays.
Put your sunscreen first and then layer it up with a moisturizer.
- Invest in a matte and non-greasy sunscreen as the skin usually gets oily and use of cream-based sunscreen can make your skin greasy.
