Why Daily UV Protection Is Essential for Healthy Skin
Sunlight helps the body make vitamin D, but its ultraviolet rays can hurt skin cells.
UVA rays go deeper into the skin and help cause wrinkles and other long-term damage.
UVB rays mostly affect the surface and cause sunburn.
Over time, this damage can contribute to skin cancers, including melanoma.
It can also make skin look older sooner.
Tanning beds are dangerous too, especially when people start using them before age 35.
Sunscreen with SPF 30 or higher can help protect the skin.
Wearing protective clothing and seeking shade between 10 a.m.
and 4 p.m.
provide additional protection.
UVA rays penetrate deeply and contribute to long-term skin damage and photoaging.
UVB rays affect the skin’s surface and directly cause sunburn.
The World Health Organization reported more than 1.5 million skin cancer cases and over 120,000 deaths globally in 2020.
Cumulative sun exposure causes about 90 percent of visible skin aging, including wrinkles, rough texture, and uneven pigmentation.
Experts recommend using at least SPF 30 daily, applying it 15 minutes before exposure, and reapplying every two hours.
