Sunscreen Buying Guide: How to Choose SPF for Everyday Use
SPF 30 or 50? Gel or cream? PA+++ or PA++++? This guide makes choosing a daily sunscreen simple — for every skin type and Indian weather.
📑 In this article (8 sections)
Sunscreen is the one skincare product almost every dermatologist recommends, yet it is also the most confusing to buy. This guide explains how to choose sunscreen SPF, what PA ratings mean, and which texture suits your skin — so you pick one you will actually wear every day.
What does SPF mean?
SPF (Sun Protection Factor) measures protection against UVB rays, which cause sunburn. In lab tests:
- SPF 15 blocks about 93% of UVB
- SPF 30 blocks about 97%
- SPF 50 blocks about 98%
The jump from 30 to 50 is small. What matters more is applying enough and reapplying.
What does PA+++ mean?
PA ratings measure protection against UVA rays, which cause tanning, pigmentation and skin ageing. More plus signs mean more UVA protection:
| Rating | UVA protection |
|---|---|
| PA+ | Some |
| PA++ | Moderate |
| PA+++ | High |
| PA++++ | Very high |
Look for "broad spectrum" or a PA rating, so you are protected from both UVA and UVB.
How to choose sunscreen for your skin type
Oily or acne-prone skin
Choose gel, fluid or "matte finish" sunscreens labelled non-comedogenic. They feel lighter in humid weather.
Dry skin
Choose cream or lotion sunscreens with hydrating ingredients such as glycerin or hyaluronic acid.
Sensitive skin
Mineral sunscreens with zinc oxide or titanium dioxide are often gentler. Choose fragrance-free formulas.
Darker skin tones
Some mineral sunscreens leave a white cast. Tinted mineral sunscreens or modern chemical filters usually blend better.
Chemical vs mineral sunscreen
| Chemical (organic) filters | Mineral (physical) filters | |
|---|---|---|
| How they work | Absorb UV | Reflect and absorb UV |
| Feel | Usually lighter, no white cast | Can feel thicker, may leave a cast |
| Good for | Daily wear, oily skin | Sensitive skin |
Both types protect well when used correctly. The best sunscreen is the one you will use consistently.
How much sunscreen should you apply?
Most people apply too little. A simple guide is the two-finger rule: squeeze sunscreen along the length of your index and middle fingers for the face and neck.
- Apply as the last step of your morning routine, before makeup.
- Wait a few minutes before going out.
- Reapply every two to three hours outdoors, and after sweating or swimming.
Common sunscreen buying mistakes
- Choosing SPF without checking for UVA protection (PA rating or broad spectrum).
- Buying a texture you dislike — you will stop using it.
- Relying only on makeup with SPF. You rarely apply enough foundation to get the full SPF.
- Using an expired sunscreen. Check the date — see how to read cosmetic expiry dates.
Sunscreen tips for different situations
- Office days: a lightweight SPF 30–50 is enough; reapply if you step out at lunch.
- Outdoor travel: choose water-resistant SPF 50, PA++++. Carry a stick or spray for reapplication.
- Gym or sport: water-resistant formula, reapply after sweating.
- Kids: use sunscreens made for children and patch test first.
