UVA in skin refers to Ultraviolet A radiation.
UVA rays are a type of ultraviolet light emitted by the sun and tanning beds that can penetrate the skin. These rays have a longer wavelength compared to UVB rays. While UVA is primarily associated with tanning and skin aging (photoaging), it can also contribute to sunburn and, more importantly, increases the risk of skin cancer.
Here's a breakdown of UVA:
- Type of Radiation: Ultraviolet radiation
- Wavelength: Longer than UVB
- Primary Effects:
- Tanning
- Skin aging (wrinkles, age spots)
- Sunburn (to a lesser extent than UVB)
- Increased risk of skin cancer
- Penetration: Can penetrate deeply into the skin
UVA radiation is present year-round and can penetrate glass, making it important to wear sunscreen even on cloudy days and indoors. Protecting your skin from UVA and UVB radiation is crucial for maintaining skin health and reducing the risk of long-term damage.
