UVA, or ultraviolet A, refers to long-wave ultraviolet radiation that penetrates deep into the skin, causing premature aging, wrinkles, and other skin damage. It is present in sunlight and can even penetrate through clouds and glass, making it a constant threat to the skin. Protecting against UVA rays is essential for maintaining healthy and youthful-looking skin.

More about UVA

UVA rays are a form of ultraviolet radiation that can deeply penetrate the skin, causing long-term damage. Unlike UVB rays, which are responsible for sunburns, UVA rays are present throughout the day, even on cloudy days, and can penetrate glass windows. This means that exposure to UVA rays is constant and can lead to cumulative skin damage over time.

It's important to protect the skin from UVA rays by using broad-spectrum sunscreen that specifically blocks UVA and UVB rays. Look for sunscreen labeled as "broad-spectrum" or with ingredients like zinc oxide or avobenzone, which provide UVA protection.

Additionally, wearing protective clothing, sunglasses, and seeking shade during peak sun hours can help reduce UVA exposure and minimize its damaging effects on the skin.
