Sunscreen is no longer something you need only at the beach or during summer. For Indian skin, daily sun protection can be particularly important if you are dealing with tanning, acne marks, melasma, uneven pigmentation or premature ageing.
But choosing a sunscreen can be confusing.
SPF 30 or SPF 50? What does PA++++ mean? Mineral or chemical? Should oily skin use sunscreen? Do you need it indoors?
Here is a practical guide.
What Does SPF Actually Mean?
SPF stands for Sun Protection Factor. It mainly indicates how well a sunscreen protects your skin against UVB radiation, which contributes to sunburn and skin damage.
For everyday use, choose a broad-spectrum sunscreen with at least SPF 30.
SPF 50 offers somewhat greater UVB protection and can be particularly useful when you spend significant time outdoors or have concerns such as melasma, pigmentation or photosensitivity.
More important than choosing between SPF 30 and SPF 50, however, is applying enough sunscreen and using it consistently.
What Does PA++++ Mean?
SPF is only part of the story.
UVA rays penetrate deeper into the skin and contribute to pigmentation and premature skin ageing.
The PA rating tells you how much UVA protection a sunscreen provides.
PA+ offers lower UVA protection, while PA++++ provides very high UVA protection.
For Indian skin that is prone to tanning and pigmentation, a broad-spectrum sunscreen with good UVA protection is usually a sensible choice.
Which Sunscreen Is Best for Oily or Acne-Prone Skin?
One of the most common things we hear is:
“Sunscreen gives me pimples.”
Often the problem is not sunscreen itself but the formulation being used.
If you have oily or acne-prone skin, look for:
- Lightweight gel, fluid or matte formulations
- Non-comedogenic products
- Sunscreens that do not feel excessively greasy
- Fragrance-free options if your skin is sensitive
Avoid choosing a sunscreen purely because it is trending on social media. A product that works beautifully for one person’s dry skin may feel completely different on oily or acne-prone skin.
What About Dry or Sensitive Skin?
Dry skin often does better with lotion or cream-based sunscreens containing moisturising ingredients.
If you have sensitive skin, eczema or frequent irritation, look for a gentle, fragrance-free formulation.
Some people tolerate mineral sunscreens containing zinc oxide or titanium dioxide better, although there is no single sunscreen type that is best for everyone.
The sunscreen you are comfortable applying every day is usually more useful than an expensive product sitting unused on your shelf.
Should You Choose a Tinted Sunscreen?
Tinted sunscreen can be particularly useful for people dealing with melasma, post-acne pigmentation and stubborn dark patches.
Visible light can contribute to pigmentation, especially in darker skin tones. Tinted sunscreens containing pigments such as iron oxides can provide additional visible-light protection compared with many conventional untinted sunscreens.
If pigmentation is your main concern, ask your dermatologist whether a tinted sunscreen would suit your skin.
How Much Sunscreen Should You Apply?
Using too little sunscreen is one of the most common mistakes.
Apply a generous, even layer to exposed areas, including:
- Face
- Ears
- Neck
- Hairline
- Hands and other exposed areas
Apply it before prolonged sun exposure rather than waiting until your skin already feels hot.
When outdoors, sunscreen generally needs to be reapplied approximately every two hours, and sooner after heavy sweating or swimming.
Do You Need Sunscreen Indoors?
You do not need to become anxious about every minute spent indoors.
However, UVA can pass through window glass. If you sit beside a sunny window for long periods, drive frequently during the daytime, or are being treated for melasma or pigmentation, daytime photoprotection can still be useful.
Your phone or laptop screen, on the other hand, should not be the main reason you wear sunscreen. Sunlight is a much more important source of visible and ultraviolet radiation.
Five Common Sunscreen Mistakes
1. Applying sunscreen only in summer
UV exposure occurs throughout the year, including on cloudy days.
2. Applying too little
A very thin layer may not provide the protection indicated on the label.
3. Forgetting the neck and ears
These areas receive regular sun exposure but are often missed.
4. Depending only on makeup with SPF
Makeup is rarely applied in the quantity needed to function as your primary sunscreen.
5. Assuming SPF 50 lasts all day
Higher SPF does not mean you can apply sunscreen once in the morning and forget about it during prolonged outdoor exposure.
Sunscreen Is Important — But It Is Not a Treatment for Everything
Sunscreen helps prevent additional UV-related damage, but it will not by itself cure acne, melasma or established pigmentation.
If you have persistent dark patches, worsening acne, recurrent irritation or pigmentation that is not improving despite consistent skincare, it may be time to identify the actual cause rather than continuing to experiment with new products.
A dermatologist can assess your skin type, current routine and underlying condition and recommend a sunscreen and treatment plan that work together.
When Should You See a Dermatologist?
Consider a consultation if:
- Pigmentation or melasma keeps returning
- Acne worsens whenever you try sunscreen
- Most skincare products sting or irritate your skin
- You develop a rash after using sunscreen
- Dark spots continue to worsen despite regular sun protection
- You are unsure which products are suitable for your skin type
The best skincare routine does not need ten products.
For many people, a gentle cleanser, suitable moisturiser, targeted treatment when needed, and consistent sun protection are a much better place to start.
