The benefits of sunblock can be viewed as a controversial topic which has been highly debated due to new scientific evidence contradicting previous scientific conclusions. However, here are some benefits of sunblock and their supporting reasons.
- Protection against Skin Cancer
Sunblock offers protection against the Sun’s UV rays, of which there are two types: UVA and UVB. Both of these types of rays contribute to skin cancer, of which the rates have been increasing in recent years.
The UVB rays can cause sunburn, skin cancer and damage to your DNA. With a depleting ozone layer, it has become more important to use protection against harmful radiation.
Sunblock offers this protection as its molecules work by ingesting UV rays and pigments that absorb, scatter and reflect UV.
Doctors advocate that most skin cancers can be aided by preventing sun damage, which can be done with the use of sunblock all year around.
- Protection against Premature Aging of the Skin
Longer wavelength UVA rays penetrate into the deeper layers of your skin and UVA exposure has been linked to premature aging of the skin, especially around the mouth, eyes and forehead. UVA exposure has also been linked to immune system problems.
Sunblock has been proven to reduce the development of premature aging skin and the formation of wrinkles. This is due to the ingredient retinyl palmitate which acts as a milder form of vitamin A. It can be an effective antioxidant and be used to stimulate skin repair.
- Protection against sunburn and skin health
Prolonged, unprotected exposure to the Sun’s UV rays can lead to sunburn, which also damages your blood vessels, causing them to thin out. This can lead to the appearance of bruising and bleeding.
Sunburn effects include the reddening, swelling and peeling of your skin. Severe sunburn leading to blistering can cause permanent skin damage. This can then increase your risk for melanoma skin cancer, as shown by the 2008 research report in the ‘Annals of Epidemiology’.
Repeated and unprotected exposure to the sun and sun damage can cause your skin to appear dry, discolored and leathery. Your skin many also develop facial brown spots or facial red veins and blotchiness.
