PA+++ Meaning in Sunscreen and Why It Matters

If you frequently use sunscreen, we are sure that you’re familiar with terms like SPF and broad-spectrum, but what about PA+++? Did you know this lesser-known rating plays a crucial role in protecting your skin, especially against the ageing and pigmentation caused by UVA rays?

At CodeSkin, where every formulation is backed by science and expertise, we believe that knowledge is the first step to better skin. Join us as we not only explore the PA+++ meaning but also understand the entire PA index and how it can help you choose better.

A Quick Guide to The PA Rating Index

The PA rating index was conceived in Japan and stands for “Protection Grade of UVA”. Unlike SPF, which measures the effectiveness of a product against UVB rays, the PA system focuses on shielding your skin from UVA rays. While the former type of radiation is a known cause for sunburn, the latter penetrates deeper, accelerating premature ageing, pigmentation, and collagen breakdown.

The rating is based on a test called Persistent Pigment Darkening (PPD), which measures how long it takes skin to tan under UVA exposure. The more plus signs you see next to PA, the higher the level of protection:

• PA+ offers some UVA protection

• PA++ gives moderate protection

• PA+++ provides high protection

• PA++++ delivers extremely high UVA protection
  
  

Any CodeSkin sunscreen is sure to be labelled as a PA++++ sunscreen because we believe in defending your skin against long-term sun damage.

PA+++ vs. PA++++: It’s Important to Understand The Difference

While both PA+++ and PA++++ ratings indicate strong UVA protection, understanding their difference can help you make smarter skincare decisions. This is especially essential if you have sensitive skin, hyperpigmentation, or spend prolonged hours outdoors.

• PA+++ provides high UVA protection, generally equating to a PPD rating of 8 to 16. This is suitable for everyday use, particularly if you’re indoors most of the time or exposed to high UV exposure (intense sunlight) in short bursts.
  
  

• PA++++ offers very high protection, with a PPD rating of 16 or more. It’s ideal for significant sun exposure, such as during beach vacations, outdoor workouts, or if you're treating melasma or post-acne pigmentation. It should be noted that sunscreen is not typically the primary line of treatment for these skin conditions, though it can help. Any sort of skin ailment should be diagnosed and treated by an appropriate healthcare professional.

Why is UVA protection critical for long-term skin health?

Protecting your skin from UVA is essential—not just for preventing visible ageing, but for preserving the skin’s structural health over time. Here are some long-term benefits of using sunscreen with strong PA ratings:

• Prevents premature ageing by reducing fine lines, wrinkles, and sagging.

• Fades hyperpigmentation and helps manage melasma and dark spots

• Protects collagen and elastin, which aids skin’s firmness and elasticity.

• Prevents uneven skin tone and keeps the complexion smooth and balanced.

• Reduces the long-term risk of skin cancer, as UVA can contribute to DNA damage over time.

SPF and PA, are they related?

While they function independently, choosing a sunscreen with both high SPF and a strong PA rating ensures broad-spectrum protection. For example, SPF 50 PA+++ means that the product blocks around 98% of UVB rays while also offering high defence against UVA exposure.

Together, they create a well-rounded shield that prevents sunburn, pigmentation, photoageing, and even DNA damage, making this combo ideal for daily skin defence. The perfect example is the CodeSkin UltraProtect Fluid Sunscreen SPF 100+ that has a PA++++ rating. All you need to do is apply it once a day to enjoy its safe and clean quadruple protection technology.

Choosing the Right PA Rating Sunscreen

To choose the right PA rating, consider your lifestyle and skin sensitivity.

• PA+ offers basic UVA protection, suitable for short indoor-outdoor transitions.

• PA++ gives moderate protection, ideal for brief daily commutes.

• PA+++ suits regular outdoor exposure, shielding against pigmentation and ageing.

• For prolonged sun exposure or sensitive skin, PA++++ offers maximum defence.

Regardless of rating, always pair it with broad-spectrum SPF for complete UV coverage and long-term protection against sun damage, premature ageing, and uneven skin tone. Consistent use is key to maintaining healthy, resilient skin over time.
