PA+++ Vs PA++++ Sunscreen: Understanding PA Ratings For Better Skin Protection

As temperatures continue to rise during peak Indian summers, sunscreen has become an essential part of daily skincare. While most people focus mainly on SPF, dermatologists and skincare experts often stress the importance of checking the PA rating as well. SPF protects the skin from UVB rays that cause sunburn, but the PA system measures protection against UVA rays, which are responsible for tanning, pigmentation, and premature ageing.

So, when choosing between PA+++ sunscreen and PA++++ sunscreen, which one offers better UVA protection during extreme summer heat?

What Does PA Rating Mean?

PA stands for “Protection Grade of UVA”. The number of plus signs indicates how effectively the sunscreen protects your skin from harmful UVA rays.

Here is a simple breakdown of sunscreen PA ratings:

• PA+ offers basic UVA protection
• PA++ provides moderate protection
• PA+++ gives high UVA protection
• PA++++ delivers extremely high UVA protection

The higher the number of plus signs, the stronger the defence against sun damage and skin ageing.

Why UVA Protection Matters In Summer

Unlike UVB rays, UVA rays can penetrate deeper into the skin and are present throughout the day, even during cloudy weather. Long exposure to UVA rays may lead to dark spots, uneven skin tone, wrinkles, and hyperpigmentation.

This is why using a broad spectrum sunscreen with a strong PA rating becomes important during Indian summers, especially when temperatures often cross 40°C in many cities.

Why PA++++ Sunscreen Is Considered Better

Higher UVA Defence

PA++++ sunscreen offers stronger UVA protection compared to PA+++. It blocks a higher percentage of harmful rays, making it more suitable for intense sunlight and prolonged outdoor exposure.
