How to Choose and Use Sunscreen in India: SPF, PA Ratings, Skin Type, and Correct Application
Sunscreen only protects well when it is broad-spectrum, applied generously, and reapplied. Learn what SPF and PA mean, how to choose for your skin type, and the sun-safety habits that matter as much as the bottle.
Key takeaways
- Choose a broad-spectrum sunscreen that protects against both UVB (shown by SPF) and UVA (often shown by a PA rating or UVA logo), with SPF 30 or higher for daily outdoor use.
- Apply generously about 15 minutes before going out and reapply at least every two hours, and after swimming, sweating, or towel drying.
- Sunscreen works best alongside shade, clothing, hats, and sunglasses, especially during the strongest midday sun.

Short answer: pick a broad-spectrum sunscreen with SPF 30 or higher and a good UVA rating such as PA+++ or PA++++, in a texture you will actually use every day. Apply a generous amount to all exposed skin about 15 minutes before going outside, and reapply at least every two hours and after sweating or swimming. Combine sunscreen with shade, clothing, and a hat, particularly in the late morning and afternoon.
Why sunscreen matters in India
Ultraviolet (UV) radiation is strong across much of India for most of the year. UVB mainly causes sunburn, while UVA penetrates deeper and contributes to tanning, pigmentation, and skin ageing. Both types can damage skin cells over time. People with all skin tones, including darker skin, can develop sun damage and pigmentation problems.
What SPF and PA mean
- SPF measures protection mainly against UVB. SPF 30 filters most UVB rays; higher SPF numbers add a little more protection but no sunscreen blocks all UV.
- PA rating (PA+ to PA++++) indicates UVA protection; more plus signs mean more UVA protection.
- Broad-spectrum on the label means the product is designed to protect against both UVA and UVB.
- Water-resistant products hold up longer during sweating or swimming but still need reapplying.
Choosing for your skin type
- Oily or acne-prone skin: gel or lightweight fluid formulas labelled non-comedogenic.
- Dry skin: cream or lotion formulas with added moisturisers.
- Sensitive skin: fragrance-free products; mineral filters such as zinc oxide or titanium dioxide are often well tolerated.
- Children: use products labelled for children and keep babies under six months out of direct sun, using shade and clothing instead.
How to apply sunscreen correctly
- Use enough: roughly half a teaspoon for the face and neck and about a shot-glass amount for the whole body.
- Do not forget ears, the back of the neck, hands, and the tops of feet.
- Apply about 15 minutes before going outdoors.
- Reapply at least every two hours, and immediately after swimming, heavy sweating, or towel drying.
- Check the expiry date and store sunscreen away from heat.
Sun-safety habits beyond sunscreen
- Seek shade when the sun is strongest, usually from late morning to mid-afternoon.
- Wear a wide-brimmed hat, UV-protective sunglasses, and loose clothing that covers the skin.
- Drink water regularly in hot weather and watch for signs of heat illness.
When to see a doctor or dermatologist
- Severe sunburn with blistering, fever, chills, or feeling unwell.
- A mole or spot that is new, changing in size, shape, or colour, bleeding, or not healing.
- A rash or itching that appears every time you use a particular sunscreen.
- Patches of pigmentation that are spreading or affecting your confidence.
Where homeopathic skin-care brands fit
Some homeopathic and herbal brands offer sunscreens, such as B&T Sunscreen Expert and SBL Sunscreen Lotion SPF 30. Judge any sunscreen by its SPF, UVA or PA rating, broad-spectrum labelling, and how comfortably you can apply enough of it every day, rather than by brand type.
A mole or skin spot that changes, bleeds, itches persistently, or does not heal should be assessed by a doctor or dermatologist without delay.
