‘Using a broad-spectrum sunscreen that provides protection against both ultraviolet A and ultraviolet B radiations, with a Sun Protection Factor(SPF) of 30 or higher, is important.’
"Ultraviolet radiation from the sun and indoor tanning beds not only can increase your risk of skin cancer but also can contribute to skin ageing," said Arianne Shadi Kourosh, of Massachusetts General Hospital, Boston, US.
The ultraviolet radiation from the sun and indoor tanning beds tend to increase the risk of skin cancer and also contribute to skin aging.
The statement further read, "Moreover, other forms of radiation, such as heat and visible light, can negatively impact the skin, as can pollution, so protecting your skin from the environment can benefit both your health and appearance."
Researchers said that habitual exposure to ultraviolet rays could cause blood vessels to become more prominent, causing skin redness, while visible light and pollution could cause uneven skin tone, especially in darker skin types.
Short wave ultraviolet B (UVB)
rays are known to cause sunburns and uneven pigmentation and long wave ultraviolet A (UVA)
and infrared radiation penetrate deeper into the skin damaging the existing collagen and reduce collagen production, resulting in wrinkles and sagging skin.
The researchers asserted the significance of an apt sunblock cream since both kinds of Ultra Violet rays- UVA and UVB-can be equally damaging to the skin.
It is essential to use a sunscreen with a Sun Protection Factor(SPF) of 30 or higher that provides both UVA and UVB protection.
"Since both types of ultraviolet (UV) rays can damage the skin, it is important to use a broad-spectrum sunscreen that provides both long wave ultraviolet A and short wave ultraviolet B protection, with an SPF of 30 or higher" Kourosh said.
