The Science Behind UVA and UVB Protection

The Science Behind UVA and UVB Protection

TL;DR

Understanding the difference between UVA and UVB rays is crucial for effective sun protection. UVA rays penetrate deeply, causing skin aging, while UVB rays cause sunburn and can lead to skin cancer. Using a broad-spectrum sunscreen shields the skin from both types of radiation, ensuring comprehensive protection.

Understanding UVA and UVB Rays

The sun emits ultraviolet (UV) radiation in two primary forms that affect the skin:

  • UVA Rays: These rays penetrate deep into the skin's layers, contributing to premature aging and long-term skin damage.

  • UVB Rays: These rays primarily affect the skin's surface, leading to sunburns and playing a significant role in the development of skin cancer.

The Importance of Broad-Spectrum SPF

A broad-spectrum sunscreen is formulated to protect against both UVA and UVB rays. The Sun Protection Factor (SPF) rating indicates the level of protection against UVB rays, which are the primary cause of sunburn. However, SPF does not measure UVA protection. To ensure adequate defense against UVA rays, it's essential to choose sunscreens labeled as broad-spectrum. 

How Sunscreens Are Tested for Broad-Spectrum Protection

In the United States, the Food and Drug Administration (FDA) uses the critical wavelength method to determine if a sunscreen can be classified as broad-spectrum. This method assesses the breadth of protection across the UV spectrum (290-400nm). For a sunscreen to be considered broad-spectrum, it must have a critical wavelength of 370nm or more.
