PA+++ vs PA++++ Sunscreen: As June 2026 is witnessing peak summer temperatures in Delhi, it becomes more important than usual to keep your skin sun-protected with a quality sunscreen. While everyone is obsessed with SPF number, which protects your skin from UVB radiation, people tend not to care about the necessary PA system, which decides the efficacy of your sunscreen in protecting you from UVA, the invisible ageing rays. But what does PA stand for, and what to choose, PA+++ or PA++++ sunscreen?
What PA Ratings Actually Mean?
PA stands for "Protection Grade of UVA," a measurement created specifically to show UVA defence levels. The plus signs indicate protection intensity:
| PA Rating | UVA Protection Level | Percentage Protection | Duration |
|---|---|---|---|
| PA+ | Low | 50 to 75 per cent | Under 4 hours |
| PA++ | Moderate | 75 to 88 per cent | 4 to 6 hours |
| PA+++ | High | 88 to 94 per cent | 8 to 12 hours |
| PA++++ | Very High | 94 per cent+ (up to 95 per cent) | Up to 16 hours |
PA++++ offers the highest defence against ageing UVA rays and is considered the gold standard for pigmentation concerns.
PA++++ Sunscreen Gives Better UVA Protection During Scorching Summer Heat
Here are 4 reasons why PA++++Sunscreens give better UVA protection during scorching summer heat:
1. Higher Protection
PA++++ filters out about 95 per cent of the UVA radiation, whereas PA+++ filters out about 90 per cent of the UVA radiation. This 5 per cent becomes very important when one is outside for longer periods in scorching summer.
2. More Durable
PA++++ sunscreen works up to 16 hours, whereas PA+++ lasts for 8-12 hours only. Longer hours in summer mean more need for longer-lasting protection.
3. More Suitable for Sensitised Skin
People with reactive, sensitised, or pigmented skin who live in hot climates, such as in India, will benefit from PA++++ sunscreen.
4. Excellent Pigment Protection
PA++++ offers 16× or more pigment protection than the unprotected skin.
PA+++ vs PA++++ Sunscreen: Which to Choose?
| Situation | PA Rating |
|---|---|
| Indoor lifestyle, mild outdoor exposure | PA+++ |
| Regular school/work days | PA+++ |
| Outdoor sports, swimming | PA++++ |
| Long sun hours (summer festivals, events) | PA++++ |
| Sensitive or reactive skin | PA++++ |
| Hyperpigmentation concerns | PA++++ |

PA+++ vs PA++++ Sunscreen: My Takeaway?
As a girl who travels in scorching Delhi heat, almost every day personally, I prioritise PA++++ for good UVA protection, because i don’t want my skin to look ageing before its time and for concerns like hyperpigmentation. I also take care of SPF number, alongside PA++++ for complete UVB and UVA coverage. Choosing broad-spectrum formulas ensures protection against both UVA and UVB radiation. And i also try to reapply my sunscreen every 2 hours, if not, then always before I step out.

However, the best way to find your perfect sunscreen is to consult an expert, especially if you have sensitive, acne-prone skin, a chronic skin allergy or any other skin-related concerns.

Lastly, PA++++ is currently one of the highest levels of UVA protection and offers much better protection than PA+++. PA+++ offers sufficient protection for people who go out only occasionally and lead indoor lives. However, PA++++ is a must-have for Indian summers, when you spend long hours outdoors, be it for festivals, beaches, or your regular commute in the summer heat of over 35°C - 40 degrees celsious. Also, remember that PA protection prevents your skin from premature ageing, dark spots, and sun damage.
