Sunscreen helps protect your skin from ultraviolet (UV) radiation, which contributes to sunburn, uneven skin tone, dark marks, visible ageing and skin cancer. To get the protection shown on the label, choose a broad-spectrum product, apply enough of it every morning as your last skincare step, and reapply when you are outdoors, sweating or swimming. Every skin tone benefits from it.
In a country as sunny as Pakistan, sunscreen is not a summer accessory; it is a daily habit.
Why does sunscreen matter so much?
UV radiation reaches us year-round, on cloudy days and through windows. It comes in two main types relevant to skin:
- UVB rays are associated mainly with sunburn.
- UVA rays penetrate deeper and contribute to visible ageing and pigmentation, and can pass through glass.
The World Health Organization's information on the UV index explains how UV strength varies through the day and why protection matters most when the index is high.
How do you read a sunscreen label?
| Label term | What it generally means |
|---|---|
| SPF (sun protection factor) | A measure mainly of protection against UVB |
| Broad spectrum | Tested protection against both UVA and UVB |
| Water resistant | Protection lasts for a stated time in water or sweat, then reapply |
| Mineral filters | Such as zinc oxide or titanium dioxide |
| Chemical (organic) filters | UV-absorbing compounds |
The U.S. Food and Drug Administration's consumer page on sunscreen explains these terms in more detail. Labelling rules vary between countries, so look for clear, tested claims.
What SPF should you choose?
The American Academy of Dermatology's advice on selecting a sunscreen recommends a broad-spectrum sunscreen with SPF 30 or higher for most people. A higher SPF offers somewhat more protection, but no sunscreen blocks all UV, and how well you apply it matters as much as the number.
How much sunscreen should you apply?
SPF values are measured using a generous amount of product. Most people apply far less, which means they get less protection than the label suggests. A common practical guide for the face and neck is two finger-lengths of sunscreen. For the whole body, the AAD's guide on how to apply sunscreen describes using about enough to fill a shot glass.
When should you reapply?
Sunscreen wears off through sweat, water, rubbing and time. General advice is to reapply about every two hours when outdoors, and immediately after swimming or heavy sweating, or as directed on the label.
How does sunscreen fit into a routine?
Sunscreen is the last skincare step in the morning, after moisturiser and before make-up:
- Cleanse
- Serum (optional)
- Moisturiser
- Sunscreen
- Make-up (optional)
Do darker skin tones need sunscreen?
Yes. More melanin offers some natural protection against sunburn, but it does not prevent UV damage, and dark marks and uneven tone often worsen with sun exposure. Sunscreen is especially important if you are using products aimed at a more even-looking complexion.
Mineral or chemical sunscreen?
Both can be effective. Mineral sunscreens use zinc oxide or titanium dioxide and may suit sensitive skin, though some leave a white cast. Chemical sunscreens often feel lighter. The best sunscreen is the one you enjoy wearing enough to use every day.
How do you find a sunscreen you will actually wear?
The best sunscreen in the world does nothing in a drawer. If you have struggled to wear sunscreen daily, the problem is often texture rather than motivation:
- If it feels greasy: try a gel, fluid or "matte" formula designed for the face.
- If it leaves a white cast: chemical-filter formulas or tinted mineral sunscreens may suit deeper skin tones better.
- If it stings your eyes: some people find mineral formulas, or sticks for the eye area, more comfortable.
- If it pills under make-up: let it settle for a few minutes before applying make-up, and use fewer layers underneath.
It can take a few tries to find the one you like. That effort pays off for years.
What does a sun-safe day outdoors look like?
Planning a wedding, a day at the beach or a long outdoor event? Apply sunscreen generously before you leave, carry it with you, and reapply roughly every two hours or after sweating. Wear a hat and sunglasses, seek shade during the middle of the day when the UV index is usually highest, and remember often-missed areas such as ears, the back of the neck and the tops of feet.
Common mistakes
- Applying too little.
- Skipping sunscreen on cloudy days or indoors near windows.
- Forgetting ears, neck, hands and the back of the neck.
- Relying on make-up with SPF alone.
- Not reapplying when outdoors.
- Assuming a face mist reapplies protection.
Beyond sunscreen
Sunscreen works best alongside other habits: seeking shade during the strongest midday sun, wearing hats and sunglasses, and covering up with clothing.
Frequently asked questions
Do I need sunscreen if I stay indoors?
If you sit near windows or step outside during the day, sunscreen is still sensible, as UVA can pass through glass.
Is SPF in make-up enough?
Usually not, because most people do not apply enough make-up to reach the labelled SPF.
Does higher SPF mean I can reapply less?
No. Reapplication depends on time, sweat and water, not just SPF.
Can sunscreen cause breakouts?
Some formulas may not suit acne-prone skin. Lightweight formulas designed for the face are often easier to wear.
Should children wear sunscreen?
Ask a doctor about sun protection for babies and young children.
In short
Choose a broad-spectrum sunscreen with a suitable SPF, apply enough every morning as your last skincare step, reapply when outdoors, and combine it with shade and clothing. It is the single most valuable habit in any routine.
