Sunscreen Ingredients for UV and Visible Light Protection

Author(s):

An expert discusses how UV radiation causes DNA damage, accelerating skin aging and cancer risk. Visible light and infrared radiation induce oxidative stress and hyperpigmentation, especially in darker skin tones. Conventional sunscreens shield against UV radiation but offer limited visible light and infrared protection. Mineral filters (zinc oxide, titanium dioxide) provide broad coverage, while chemical filters (oxybenzone, avobenzone) absorb UV radiation but lack efficacy against visible and infrared radiation.
