Do You Need Sunscreen in Winter? (Yes — Here Is Why)

The short answer

Yes, you need sunscreen every day in winter. UVB, the burning ray, does drop in winter. UVA does not. UVA is what drives pigmentation, melasma and ageing, and it passes through cloud, haze and window glass all year round. What you change in winter is the texture: a moisturising sunscreen instead of a matte gel, such as Skin Aqua Super Moisture UV Gel or Dot & Key Blueberry Hydrate Barrier Repair Sunscreen.

UVA vs UVB: why the difference matters

• UVB burns the skin. In winter the sun sits lower, so UVB falls, which is why you rarely feel sunburnt in winter.
• UVA goes deeper, darkens spots, worsens melasma, and causes ageing (lines, sagging). It changes much less with the seasons.

So the winter feeling of "the sun is not strong" is really the drop in UVB. Most of the damage carries on quietly. The SPF number mainly describes UVB protection; for UVA, look for PA+++ or PA++++, or "broad spectrum" on the label.

Five myths, and the facts

1. "Dhaka’s winter haze blocks the sun"

No. Smog scatters light; it does not meaningfully absorb UVA. The sun looks weak through the haze, but the UVA behind pigmentation and ageing still reaches your skin.

2. "It is fine to pause dark-spot care in winter"

It is not. Melasma worsens without winter protection. If you are treating dark spots, stopping sunscreen in winter can undo months of work, because UVA keeps driving pigmentation through the colder months.

3. "Sunscreen dries out dry skin"

The wrong texture feels uncomfortable, but the fix is not skipping sunscreen. Switch the texture, do not skip it. A cream or hydrating sunscreen suits dry winter skin better than a matte gel. Browse verified sunscreens.

4. "I do not need it indoors"

You do if you sit near a window, because UVA passes through glass. If you are in a windowless room all day, the need is lower.

5. "I have to reapply all day"

Reapply every 2–3 hours when outdoors. If you are inside all day, one morning application is reasonable.

How to apply it in winter

• Order: cleanse → moisturizer → wait 2–3 minutes → sunscreen. Sunscreen is the last skincare step in the morning.
• Amount: two finger-lengths for the face and neck. Using less does not give half the protection; it gives much less.
• Forgotten spots: ears, sides of the neck, backs of the hands. These catch the most sun on a bike or rickshaw.
• On dry days: a slightly richer moisturizer underneath stops sunscreen looking flaky.

For the whole family: men, teenagers and children

• Men: many men assume sunscreen is a summer thing, or a women’s thing. Yet riding a bike to the office or playing in the field puts the most sun on the forehead, nose and upper cheeks, which is exactly where dark patches and tanning show first. Moisturizer after shaving, then sunscreen.
• Teenagers: school grounds, college fields, walking to coaching. A sunscreen habit built at this age lasts a lifetime. Choose a mild sunscreen suitable for sensitive skin.
• Children: there are separate guidelines on the age at which a baby can use sunscreen. For very young children, shade, a hat and clothing are the main protection. Parents should ask a paediatrician.

Why it matters even more in a Bangladeshi winter

Winter afternoons are the most pleasant time of year here: sitting in the sun on the roof, cricket in the field, wedding invitations, picnics, and winter-holiday trips to Cox’s Bazar or Sylhet. We often spend more time in the sun than in summer because it does not feel hot. On the beach, sand and water reflect sunlight and add to the exposure. So for long hours outdoors in winter, reapply sunscreen along with a hat or umbrella. For the full routine, read the full winter routine.

When to see a doctor

If you get itching, a red rash or swelling after applying sunscreen, stop using it and see a doctor if it does not settle. If melasma spreads quickly despite regular sunscreen, or a mole suddenly changes size or colour, see a dermatologist.
