What is the difference between UVA, UVB, and UVC rays?

What is the difference between UVA, UVB, and UVC rays?

UVA rays penetrate the skin deeply and are associated with aging. UVB rays affect the surface and are responsible for sunburn. UVC rays are the most harmful but are mostly absorbed by the Earth's atmosphere.

How do these rays affect my skin?

UVA rays can lead to premature aging and skin cancer, while UVB rays cause sunburn and can also contribute to skin cancer. UVC rays are generally not a concern for skin since they don't reach us.

What type of sunscreen should I use?

Look for broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF of at least 30 for effective protection.

Are there any specific times when UV exposure is higher?

Yes, UV exposure is typically higher between 10 AM and 4 PM, especially during summer months. It's best to seek shade during these hours.

Can UV rays penetrate windows?

Yes, UVA rays can penetrate windows, which is why it's important to use window films or UV-blocking treatments if you're indoors for long periods.
