SPF 50 PA+++ Explained: How to Pick the Right Sunscreen for Your Skin
What SPF and PA actually measure
SPF (Sun Protection Factor) measures protection against UVB rays — the ones responsible for sunburn. SPF 50
means your skin can theoretically tolerate 50 times more UVB exposure before burning, compared to bare skin. PA (Protection Grade of UVA), on the other hand, measures protection against UVA rays — the ones linked to tanning, premature ageing, and long-term pigmentation. PA+++ is one of the highest available ratings, meaning strong UVA protection alongside your SPF number. For daily wear in Indian conditions, dermatologists generally recommend at least SPF 50 with PA+++ — which is exactly why Costak's sunscreens are formulated at this level rather than a lower, less protective rating.

Why Indian weather needs both numbers, not just one
A lot of sunscreen shopping in India still focuses on SPF alone, but that only tells half the story. High humidity, intense midday UV index, and long outdoor commutes mean UVA exposure adds up fast — even on cloudy days, even through car windows. That's the pigmentation and dullness people notice building up over months, not just the sunburn from one afternoon out. Choosing SPF 50 PA+++ covers both fronts at once, instead of leaving your skin under-protected on the UVA side.
Matte gel or lotion — which one is right for you?
Costak's SPF 50 PA+++ range comes in two textures. The Matte Sunscreen Gel is built for oily and combination skin — it sets to a lightweight, no-shine finish and layers well under makeup. The Golden Sands Detan Sunscreen Body Lotion is a more hydrating, body-friendly format, better suited for normal-to-dry skin or anywhere you want a bit of extra moisture alongside the SPF. Neither leaves a white cast, and both are reapplication-friendly for long days outdoors.

How much to apply (most people use too little)
The standard dermatologist guidance is about a quarter-teaspoon (roughly two finger-lengths) for the face alone, applied 15–20 minutes before sun exposure and reapplied every 2–3 hours if you're outdoors, sweating, or after swimming. Using less than this — which is extremely common — quietly lowers your real-world protection well below the number on the bottle.

FAQs
Does sunscreen prevent tanning completely?
It significantly reduces tanning and pigmentation caused by UV exposure, but no sunscreen blocks 100% of UV rays. Consistent daily use, reapplication, and an adequate amount are what actually determine how well it works in practice.
Can I use sunscreen every day, even indoors?
Yes — UVA rays penetrate glass and clouds, so daily use is recommended even on indoor or overcast days, not just for direct beach or outdoor exposure.
