Quick answer: How to choose sunscreen comes down to three label words: broad spectrum, SPF 30 or higher and water resistant. Then pick a texture you’ll wear every day, apply enough 15 minutes before going out, and reapply every two hours outdoors. Amount and reapplication matter more than a very high SPF.

When people ask how to choose sunscreen, Pakistani shop pages can’t agree on SPF. Some say 40. Others say 60 or more. A few push 100. The truth is that the number on the front isn’t the word that matters most.

This guide explains the label in plain words, gives you a three-question check, and shows how to match a sunscreen to your skin type. It’s part of our skincare series, so if you’re building a full routine, start with the best skincare products in Pakistan guide.

What do the words on a sunscreen label mean?

The American Academy of Dermatology advises choosing a sunscreen that says three things. Here is what each one means.

Some labels also show a “PA” rating, such as PA+++. I couldn’t find AAD guidance on it, so I’d use “broad spectrum” as your check instead.

How much SPF do you really need?

Less than you think. The Skin Cancer Foundation explains that SPF 15 filters about 93 percent of UVB rays, SPF 30 about 97 percent and SPF 50 about 98 percent. No sunscreen filters out all UV radiation.

That’s a small step from 30 to 50. So the AAD sets the baseline at SPF 30 or higher, and the Skin Cancer Foundation says SPF 30 is fine for daily use. For long hours outdoors, it suggests a water-resistant formula with SPF 50 or more. A very high number doesn’t let you skip reapplying.

How to choose sunscreen: the three-question check

Here’s how to choose sunscreen with the method I’d use before buying. It’s my own, built on the AAD and Skin Cancer Foundation advice above.

1. How long will I be outside? For ordinary days, SPF 30 or higher is enough. For long hours outdoors, choose SPF 50 or more with water resistance.
2. Which texture suits my skin? Match it to your skin type, using the table below.
3. Will I really wear it every day? The best sunscreen is the one you’ll use. A texture you hate stays in the drawer.

How much sunscreen should you use, and how often?

This is where most people go wrong, not at the shop. The AAD’s advice on applying sunscreen is simple:

• Use enough. About one ounce, enough to fill a shot glass, covers the exposed areas of the body.
• Apply it to dry skin about 15 minutes before going outdoors.
• Cover all skin that clothing doesn’t.
• Reapply every two hours when outdoors, and after swimming or sweating.

People who get sunburned usually didn’t use enough, didn’t reapply, or used an expired product, according to AAD advice. An AAD survey found that only 33 percent of people typically reapply every two hours. Check the expiry date on your tube, and keep sunscreen away from heat. As the FDA advises for cosmetics, throw away a product if its colour or smell changes.

Do you need sunscreen on cloudy days and in winter?

Yes. AAD guidance says your skin is exposed to UV rays every time you go outside, even on cloudy days and in winter. That’s why our winter skincare routine keeps sunscreen in the morning, and why the skincare for humid weather guide does the same.

The AAD also recommends sunscreen for anyone planning to spend time outside. That includes people with darker skin tones.

Is sunscreen enough on its own?

No. The AAD reminds us that sunscreen alone can’t fully protect you. Seek shade, wear sun-protective clothing, a wide-brimmed hat and sunglasses when you can, and use a lip balm with at least SPF 15 for your lips.

How to choose sunscreen when you buy online in Pakistan

You can’t read the label in your hand, so ask for it. Before you order, check these things:

1. The label says broad spectrum, shows the SPF and lists water resistance (40 or 80 minutes).
2. A clear photo of the back label, the ingredient list and the expiry date.
3. No “miracle” claims, such as total protection. No sunscreen filters out all UV rays.
4. An intact seal when the parcel arrives, with no change in colour or smell.
5. A patch test before it goes on your face. Our guide to patch test skincare shows how.

FAQs about how to choose sunscreen

Which SPF is best for Pakistan?

The AAD recommends SPF 30 or higher, broad spectrum and water resistant. For long hours outdoors, the Skin Cancer Foundation suggests a water-resistant formula with SPF 50 or more. Whatever you pick, apply enough and reapply every two hours outdoors.

Is a higher SPF always better?

Not by much. SPF 30 filters about 97 percent of UVB rays and SPF 50 about 98 percent. A higher number gives only a small increase, and it doesn’t mean you can stay in the sun longer without reapplying.

Does water resistant mean waterproof?

No. Water resistant means the sunscreen stays on wet or sweaty skin for 40 or 80 minutes, as the label states. No sunscreen is waterproof or sweatproof, so you still need to reapply every two hours.

Can you use a moisturizer with SPF instead of sunscreen?

Yes, if it is broad spectrum with SPF 30 or higher, and you apply enough of it. A moisturizer with SPF can save a step. Apply it generously, and reapply when you’re outdoors for long.

Do you need sunscreen if you have darker skin?

Yes. The AAD recommends sunscreen for anyone who plans to spend time outside. Choose a broad-spectrum, SPF 30 or higher, water-resistant product that feels comfortable enough to wear every day.

How long does sunscreen last?

Check the expiry date on the pack. An expired sunscreen may not protect you properly, according to AAD advice. Throw it away if the colour or smell changes, and keep it away from heat.
