Most sunscreens on the market protect well against solar UVB radiation but have limited effectiveness against UVA-induced damage, relying on the reflective properties of creams to defend against dangerous UVA rays. However, this compound, called the mitoiron claw by the team, offers strong protection within our cells precisely where the greatest damage from UVA occurs, and doesn't interfere with rest of the cell. The researchers from the University of Bath, working with colleagues at Kings College London, hope to see the mitoiron claw compound added to sunscreens and skin care products within 3 to 4 years.
Choose a sunscreen with an SPF 30 or higher. While no sunscreen can filter out all of the suns UVB rays, SPF 30 sunscreens block 97 percent of the suns UVB rays. Look for the words broad spectrum. This means the sunscreen will protect against both UVA rays - which cause premature skin aging - and UVB rays - which cause sunburn. Both types of UV rays can lead to skin cancer.
Environmental factors can damage the skin in multiple ways, from UVB rays causing sunburns and uneven pigmentation to UVA and infrared radiation penetrating more deeply into the skin to damage existing collagen and reduce collagen production, resulting in wrinkles and sagging skin. Habitual UV exposure can cause blood vessels to become more prominent, causing skin redness while visible light and pollution can cause uneven skin tone, especially in darker skin types.
