Most people know they should use sunscreen.
The problem is that many people are still unsure about what actually matters.
Should you use SPF 30 or SPF 50?
Is SPF 100 better?
Does sunscreen need to be worn indoors?
How much should you apply?
Should you reapply if you’re working in an office?
And if you are treating melasma or pigmentation, why does your pigmentation sometimes continue to get darker despite using sunscreen every day?
These are not minor details.
The sunscreen you choose, the amount you apply, how often you reapply and the type of light you are protecting against can all matter—particularly for Indian skin that is prone to pigmentation.
For patients with melasma or hyperpigmentation, sunscreen isn’t simply the final step of a skincare routine.
It is part of the treatment.
The American Academy of Dermatology recommends a broad-spectrum sunscreen with SPF 30 or higher, with water resistance being particularly useful for outdoor exposure. For pigmentation-prone darker skin tones, tinted sunscreen containing iron oxides can provide additional protection against visible light.
At Skination Clinic, we often see patients from Chattarpur and South Delhi as well as Faridabad who are diligently using sunscreen but still struggling with pigmentation.
Often, the problem isn’t that they are not using sunscreen.
It is that they are not using it in the way their skin actually needs.
Does Indian skin really need sunscreen?
Absolutely.
There is a misconception that darker or brown skin is naturally protected enough from the sun.
Melanin does provide some natural photoprotection, but it does not eliminate the effects of UV exposure or visible light.
Sun exposure can contribute to:
* Tanning
* Uneven pigmentation
* Melasma
* Post-inflammatory hyperpigmentation
* Premature skin ageing
* Wrinkles
* Uneven skin tone
* Photodamage
People with darker skin tones can also develop skin cancer, although the risk and pattern can differ from those in lighter skin. Dermatologists recommend sun protection for all skin tones.
But for many Indian patients, the most immediate concern isn’t skin cancer.
It is:
“Why is my pigmentation getting darker?”
And this is where sunscreen becomes particularly important.
SPF 30 vs SPF 50: Which one should you choose?
This is one of the most common sunscreen questions.
SPF 30 is already meaningful protection.
SPF primarily describes protection against UVB, the radiation strongly associated with sunburn.
An SPF 30 sunscreen filters approximately 97% of UVB under standard testing conditions.
Higher SPF provides somewhat greater UVB protection, but no sunscreen blocks 100% of UVB.
So does that mean SPF 50 is unnecessary?
Not necessarily.
In real life, people often apply considerably less sunscreen than the amount used during SPF testing. The American Academy of Dermatology notes that many people apply only a fraction of the amount needed to achieve the labelled SPF.
Therefore, for someone who is highly pigmentation-prone or spends significant time outdoors, I generally prefer a well-formulated SPF 50 broad-spectrum sunscreen that the patient will apply generously and consistently.
The most expensive SPF 100 sunscreen is useless if you apply too little.
Is SPF 100 much better than SPF 50?
Not in the way many people imagine.
SPF numbers are not percentages of protection.
Going from SPF 30 to SPF 50 does not mean you are getting 67% more protection.
The increase in UVB protection becomes progressively smaller at higher SPF values.
More importantly:
SPF 50 does not mean you can stay in the sun 50 times longer than without sunscreen.
A higher SPF also doesn’t mean you can skip reapplication.
When outdoors, sunscreen generally needs to be reapplied approximately every two hours and sooner after swimming or significant sweating.
What does “broad-spectrum” mean?
This is more important than simply looking at the SPF number.
Broad-spectrum protection means protection against both UVA and UVB.
UVB is strongly associated with sunburn.
UVA penetrates deeper into the skin and contributes substantially to photoageing and pigmentation.
Therefore, if you are buying sunscreen for daily facial use, don’t simply ask:
“What is the SPF?”
Look for:
SPF 30 or higher + broad-spectrum protection.
For people with significant outdoor exposure, a water-resistant formulation can also be useful.
Why is your pigmentation still getting worse despite sunscreen?
This is where things get more interesting.
You may genuinely be using sunscreen every day and still notice:
“My melasma is getting darker.”
There can be several reasons.
1. You’re not applying enough
This is probably one of the biggest problems.
The SPF written on the bottle is determined under standard testing conditions using a specific amount of product.
If you apply half that amount, you should not expect the same level of protection.
2. You’re not covering all exposed areas
Commonly missed areas include:
* Hairline
* Temples
* Around the eyes
* Ears
* Jawline
* Neck
And if you are treating facial pigmentation, applying sunscreen only to the centre of the face isn’t enough.
The American Academy of Dermatology specifically recommends applying sunscreen to all skin not covered by clothing.
3. You don’t reapply during prolonged outdoor exposure
Morning sunscreen isn’t necessarily enough for an entire day spent outdoors.
If you are:
* Driving for long periods
* Walking outdoors
* Exercising
* Travelling
* Swimming
* Sweating
your protection can decrease.
Reapply approximately every two hours while outdoors and after swimming or sweating.
But there is another reason: visible light
This is particularly relevant for Indian skin and pigmentation.
When we talk about sun protection, most people think about UV radiation.
But sunlight also contains visible light.
Research has shown that visible light can contribute to hyperpigmentation, particularly in people with darker skin tones. It can also worsen melasma.
This explains why a person may say:
“I use sunscreen every morning but my pigmentation still gets worse.”
If they are using a non-tinted sunscreen, they may be getting good UV protection but less protection against visible light.
This is one reason tinted sunscreens have become particularly relevant for patients with melasma and pigmentation.
Why is tinted sunscreen different?
A tinted sunscreen contains pigments that provide visible-light protection.
Look particularly for iron oxides in the ingredient list.
Iron oxides can help protect against visible light and are particularly useful for people prone to hyperpigmentation and melasma.
So for someone with:
* Melasma
* Post-inflammatory pigmentation
* Dark spots
* A tendency to develop pigmentation after acne
* Deeper Indian skin tones with pigmentation concerns
I may prefer a tinted, broad-spectrum sunscreen containing iron oxides, provided the formulation suits the person’s skin.
This doesn’t mean every person needs a tinted sunscreen.
For someone whose primary concern is sunburn or general photoprotection, an elegant non-tinted sunscreen may be perfectly appropriate.
Does sunscreen need to be tinted if I don’t have pigmentation?
Not necessarily.
A good sunscreen should be:
* Broad-spectrum
* SPF 30 or higher
* Appropriate for your skin type
* Comfortable enough to use consistently
Tint becomes particularly useful when visible-light protection and pigmentation control are important.
In other words:
The best sunscreen isn’t necessarily the same for everyone.
How much sunscreen should you actually apply?
This is probably more important than whether you choose SPF 50 or SPF 70.
A useful practical approach for the face is the two-finger method, where sunscreen is dispensed along the length of two fingers.
However, finger-based measurements vary between products, finger sizes and formulations.
The more fundamental principle is:
Apply enough to provide the protection claimed on the label.
The AAD notes that an adult generally needs about 1 ounce of sunscreen to cover exposed body skin, with approximately a teaspoon for the face in its guidance.
For everyday facial application, many dermatologists use a practical two-finger amount for the face and neck, adjusting according to the product and area being covered.
If you’re unsure, ask your dermatologist to demonstrate the amount appropriate for your specific product.
Should sunscreen be applied to the neck?
Yes.
The neck is frequently forgotten.
And if you’re treating pigmentation or signs of photoageing, leaving the neck unprotected while protecting the face creates an obvious problem.
Apply sunscreen to:
* Face
* Ears
* Neck
* Exposed upper chest
and other uncovered areas when outdoors.
Do you need sunscreen indoors?
This question needs a more nuanced answer than:
“Yes, sunscreen must be worn indoors 24/7.”
If you spend the entire day indoors away from significant sunlight, your exposure is very different from someone sitting beside a bright window or repeatedly going outside.
UVA can pass through window glass, while UVB is largely blocked by ordinary window glass.
For someone with melasma or significant pigmentation, consistent daytime photoprotection can be particularly useful because treatment aims to minimise ongoing light exposure.
So I don’t think the question should simply be:
“Do I need sunscreen indoors?”
Instead:
“How much meaningful light exposure am I getting during the day, and what is my pigmentation condition?”
What about sunscreen while driving?
This is an important consideration in India.
If you spend substantial time driving, especially during daylight, your face and exposed areas can receive repeated sunlight through vehicle windows.
For someone with melasma or pigmentation, daily photoprotection becomes particularly relevant.
And remember:
Sunscreen isn’t the only tool.
A combination of:
* Sunscreen
* Sunglasses
* Protective clothing
* Shade
* Window protection where appropriate
can provide more comprehensive photoprotection than relying on sunscreen alone.
What sunscreen is best for oily or acne-prone Indian skin?
The best sunscreen is one you can comfortably use every day.
For oily or acne-prone skin, look for formulations described as:
* Non-comedogenic
* Lightweight
* Gel or fluid, if preferred
* Suitable for oily skin
But don’t assume that a product marketed as “oil-free” will automatically suit your skin.
Texture and tolerability matter.
If your sunscreen makes you excessively greasy, pills under makeup or causes breakouts, you are much less likely to apply enough of it.
Consistency beats theoretical perfection.
What sunscreen is best for dry or sensitive skin?
For dry or sensitive skin, a more moisturising formulation may be preferable.
Look for a product that:
* Doesn’t sting
* Doesn’t cause excessive dryness
* Is fragrance-free if you’re sensitive to fragrance
* Provides broad-spectrum protection
* Is comfortable enough for daily use
If a sunscreen consistently burns or irritates your skin, don’t force yourself to keep using it simply because its SPF is high.
A dermatologist can help identify a better formulation.
Can sunscreen cause acne?
Some sunscreens can contribute to breakouts in people who are acne-prone, particularly if the formulation is heavy or occlusive for their skin.
But sunscreen itself is not inherently “bad for acne.”
If you have acne-prone skin, the goal is to find a non-comedogenic, lightweight formulation that you can apply in an adequate amount.
And remember:
Sun exposure does not treat acne.
Tanning can temporarily make redness appear less noticeable, but UV exposure contributes to skin damage and can worsen post-inflammatory pigmentation.
Can sunscreen make pigmentation worse?
A sunscreen should not inherently make pigmentation worse.
But a particular formulation can sometimes cause irritation, allergy or acne, which may then lead to post-inflammatory pigmentation in susceptible skin.
This is particularly relevant in Indian skin.
If every sunscreen you try causes:
* Burning
* Itching
* Rash
* Breakouts
the answer isn’t to stop sunscreen altogether.
It is to find a formulation that your skin tolerates.
Is mineral sunscreen better than chemical sunscreen?
This is one of the most persistent sunscreen debates online.
The reality is that both mineral and organic/chemical UV filters can provide effective photoprotection when appropriately formulated and tested.
Mineral sunscreens commonly use filters such as zinc oxide or titanium dioxide.
Other sunscreens use organic UV filters.
Rather than choosing purely based on whether the sunscreen is labelled “mineral” or “chemical,” consider:
* Broad-spectrum protection
* SPF
* Water resistance when relevant
* Skin tolerability
* Cosmetic elegance
* Whether you will actually apply enough
For pigmentation, tint and iron oxide content may matter more than simply whether the sunscreen is mineral or chemical.
Is sunscreen enough to prevent pigmentation?
No.
Sunscreen is extremely important, but it should be part of a broader photoprotection strategy.
For pigmentation-prone skin, particularly melasma, consider:
Sunscreen
Use appropriate broad-spectrum protection, with tinted iron-oxide-containing formulations being particularly useful for visible-light protection.
Shade
Avoid unnecessary direct sun exposure when possible.
Clothing
Hats, sunglasses and protective clothing can add another layer of protection.
Appropriate pigmentation treatment
If you have melasma, acne pigmentation or another pigmentary disorder, sunscreen alone may not be sufficient.
The underlying condition may require dermatological treatment.
Why does melasma keep returning?
Melasma is not simply “sun tanning.”
It is a complex pigmentary condition influenced by multiple factors, including light exposure, hormonal influences and individual susceptibility.
Sunlight can trigger or worsen melasma, and visible light can also contribute, particularly in darker skin tones.
That is why someone may successfully lighten their melasma and then see it return after repeated sun exposure.
Treatment isn’t only about removing existing pigment.
It is also about preventing the melanocytes from being repeatedly stimulated.
Photoprotection is therefore a core component of melasma management.
The most common sunscreen mistakes I see
Mistake 1: Using too little
Probably the most common.
Mistake 2: Applying only once in the morning
Fine for some low-exposure days, but inadequate for prolonged outdoor exposure.
Mistake 3: Forgetting the neck
Extremely common.
Mistake 4: Choosing SPF but ignoring broad-spectrum protection
SPF alone doesn’t tell you the whole story.
Mistake 5: Using a non-tinted sunscreen for severe melasma
It may provide excellent UV protection but less visible-light protection.
Mistake 6: Applying sunscreen only when it’s sunny
UV exposure doesn’t disappear simply because clouds are present.
Mistake 7: Stopping sunscreen once pigmentation improves
This is one of the biggest reasons pigmentation can recur.
Mistake 8: Choosing a sunscreen you hate wearing
If you don’t like the texture, you’ll eventually stop using it—or use too little.
So, what sunscreen should you actually choose?
For most adults, a sensible starting point is:
Broad-spectrum SPF 30 or higher.
For someone with significant pigmentation or high sun exposure, I commonly favour:
Broad-spectrum SPF 50, with a formulation appropriate for the patient’s skin type.
For melasma or significant hyperpigmentation, consider:
Tinted sunscreen containing iron oxides, because visible-light protection becomes particularly relevant.
And for someone who sweats heavily or spends significant time outdoors:
Water resistance can be valuable.
But the “best sunscreen” isn’t a particular brand.
It is the one that:
provides appropriate protection + suits your skin + you apply generously + you reapply when needed + you will actually use consistently.
What I tell patients at Skination
When a patient tells me:
“Doctor, I use sunscreen every day but my pigmentation isn’t improving,”
I don’t immediately change the pigmentation medication.
I ask:
* Which sunscreen are you using?
* Is it broad-spectrum?
* What SPF is it?
* Is it tinted?
* Does it contain iron oxides?
* How much are you applying?
* Are you covering the neck?
* Do you reapply?
* How much time do you spend outdoors?
* Do you drive frequently?
* Are you using a hat or other protection?
* Are you treating the underlying pigmentation condition appropriately?
Because sunscreen isn’t simply a product.
It is a behaviour.
And small differences in how it is used can have a significant effect on long-term results.
The bottom line
You don’t need to buy the most expensive sunscreen on the market.
You need to understand what your skin actually requires.
For most people:
SPF 30+ + broad-spectrum protection + adequate application
is a strong foundation.
For people with melasma or pigmentation-prone Indian skin, tinted sunscreen containing iron oxides can provide an additional advantage by helping protect against visible light, which can contribute to hyperpigmentation.
And remember:
SPF 50 applied too thinly is not the same as properly applied SPF 50.
If your pigmentation continues to worsen despite diligent sunscreen use, don’t simply keep changing sunscreens.
The problem may be the pigmentation diagnosis itself, the application routine, visible-light exposure, or another factor that needs dermatological evaluation.
At Skination Clinic, patients can consult at our Chattarpur clinic in South Delhi or our Faridabad clinic for personalised assessment of pigmentation, melasma, acne and photoageing.
Because effective sun protection isn’t about finding the “perfect sunscreen.”
It’s about finding the right protection for your skin—and using it correctly.
Frequently Asked Questions
For most adults, dermatologists recommend broad-spectrum SPF 30 or higher. SPF 50 can be a practical choice for people with significant sun exposure or pigmentation concerns, particularly because people often apply less sunscreen than the amount used during SPF testing.
2. Is SPF 50 better than SPF 30?
SPF 50 provides somewhat greater UVB protection than SPF 30, but the difference is not as large as the numbers might suggest. Correct application and reapplication are extremely important. No SPF provides complete protection from UV radiation.
3. How much sunscreen should I apply to my face?
Use enough to adequately cover the exposed skin. A practical facial approach commonly used by dermatologists is the two-finger method, although the exact amount varies with product and the area being covered. The AAD recommends approximately a teaspoon for the face in its general application guidance.
4. How often should sunscreen be reapplied?
When you are outdoors, reapply approximately every two hours and sooner after swimming or significant sweating.
5. Is tinted sunscreen better for pigmentation?
For people with melasma or hyperpigmentation, tinted sunscreen containing iron oxides can provide additional protection against visible light, which can worsen pigmentation, particularly in darker skin tones.
6. Why is my pigmentation getting darker even though I use sunscreen?
Possible reasons include insufficient application, inadequate reapplication, significant sun exposure, lack of visible-light protection, or an underlying pigmentary condition that requires additional treatment. Your sunscreen may also be irritating your skin, causing additional post-inflammatory pigmentation.
7. Does sunscreen prevent melasma from coming back?
Good photoprotection can reduce triggers for melasma and is an important part of preventing recurrence, but sunscreen alone does not guarantee that melasma will never return. Melasma is influenced by multiple factors.
8. Do people with darker Indian skin need sunscreen?
Yes. Darker skin has some natural protection from melanin, but it does not eliminate UV-related skin damage or pigmentation. Visible light can also contribute to hyperpigmentation in darker skin tones.
9. Do I need sunscreen indoors?
It depends on your exposure. If you spend most of the day away from meaningful sunlight, your exposure is different from someone sitting beside windows or frequently going outdoors. For people with melasma or significant pigmentation, consistent daytime photoprotection can be particularly useful.
10. Is mineral sunscreen better for Indian skin?
Not automatically. Both mineral and organic/chemical UV filters can provide effective protection when appropriately formulated. The important factors include broad-spectrum protection, adequate SPF, tolerability and whether you will use enough sunscreen consistently.
11. Can sunscreen cause acne?
Some formulations can aggravate acne-prone skin, but sunscreen itself does not inherently cause acne. If you are acne-prone, choose a lightweight, non-comedogenic formulation that you can comfortably apply in an adequate amount.
12. Do I need sunscreen on my neck?
Yes. The neck is exposed to sunlight and is commonly forgotten. Apply sunscreen to the face, ears, neck and other exposed areas.
