Understanding UVA Rays
UVA rays make up approximately 95% of the UV radiation reaching the Earth's surface. These rays penetrate the skin more deeply than UVB rays, reaching the dermis, which is the skin's thickest layer. Although UVA rays are less intense than UVB rays, they are present with relatively equal intensity during all daylight hours throughout the year.
Effects of UVA Rays
UVA rays contribute to skin aging and wrinkling, often leading to photoaging. They play a role in some skin cancers and can penetrate through clouds and glass, making it vital to consider protection even on cloudy days or when indoors near windows.
Understanding UVB Rays
UVB rays account for a smaller fraction of UV radiation but are significantly more intense than UVA rays. They are primarily responsible for skin reddening and sunburn and tend to damage the skin's outer layers. UVB rays' intensity varies depending on time of day, season, and altitude.
Effects of UVB Rays
UVB rays are the primary cause of sunburn and are believed to play a significant part in causing skin cancers. Unlike UVA, UVB rays do not penetrate glass, meaning your exposure to them is reduced indoors.
Impact of UVA and UVB on Skin Health
Both UVA and UVB rays contribute to skin cancer risk. UVA rays penetrate deeper into the skin, potentially causing long-term damage, while UVB rays are more likely to cause immediate harm through sunburn.

Research has shown that both UVA and UVB can suppress the immune system and cause damage to the DNA in our skin cells, thus increasing the risk of cancer. Regularly monitoring your UV exposure is crucial, a task made easier with the TanMeter app, which tracks the UV index and sends you reminders to apply sunscreen based on your specific skin type.
The Role of SPF in Sun Protection
SPF, or Sun Protection Factor, is crucial when it comes to safeguarding your skin from harmful rays. It's important to use a broad-spectrum sunscreen with at least SPF 30, as it can protect against both UVA and UVB rays. Reapplying sunscreen every two hours or after swimming and sweating is also recommended.
