For the monsoon, choose a light gel, fluid or milk SPF50+ PA++++ sunscreen, ideally one labelled water-resistant or waterproof, and reapply every 2 to 3 hours when you are outdoors. For heavy sweat, Missha Water Proof Sun Milk; for oily skin, Biore UV Aqua Rich Watery Essence; for normal to dry skin, Isntree Hyaluronic Acid Watery Sun Gel; and for sensitive skin, SKIN1004 Centella Air-Fit Suncream Light SPF50. Keep a sun stick for touch-ups during the day.
Why you need sunscreen on cloudy days
Up to 80% of UV passes through clouds. On a grey, rainy day in Dhaka you may not see the sun, but the processes that cause dullness, dark spots and ageing keep going. And in the monsoon the sun often breaks through strongly between showers, with extra glare off wet roads.
The real monsoon problems are two:
- Sweat and rain wash sunscreen off. With high humidity, sweat does not evaporate; it runs down your face and takes the sunscreen with it.
- Heavy creams feel unbearable in humidity. Because of the sticky feel, many people skip sunscreen altogether, and heavy formulas can clog pores and cause breakouts.
So the monsoon needs two things together: a texture you will actually reapply, and the habit of reapplying.
What to look for in a monsoon sunscreen
- SPF50+ with PA+++ or PA++++. SPF protects against burning; the PA rating covers UVA, which causes dark spots and ageing.
- A "water-resistant" or "waterproof" claim. Check the label on each tube yourself; not every lightweight sunscreen is sweat-resistant. And remember, water-resistant does not mean all-day: after sweating or rain you still need to blot and reapply.
- A light texture: watery gel, fluid or sun milk. If it sinks in within a minute, you are on the right track.
- No white cast, and no pilling under a mask or helmet.

How to use sunscreen on rainy days
- Amount: two finger-lengths for face and neck. Less than that and you do not get the SPF on the label.
- Timing: apply 15 minutes before heading out so it can set. Putting on a helmet or mask straight after applying rubs it off.
- Reapply: every 2 to 3 hours outdoors, and straight away after heavy sweating or getting caught in the rain.
- Before reapplying: blot sweat and water with a tissue (press, do not rub), then add a fresh layer.
- Sun stick: on makeup days or busy days a stick is easiest, since you do not need to wash your hands. Sticks put on less product, so go over your face several times.
- Neck, ears, backs of hands: these get the most sun on a rickshaw or bike.
For reapplying over makeup, see reapplying sunscreen over makeup.
Common monsoon mistakes
- "There is no sun today." Clouds do not block UV fully.
- Layering fresh sunscreen onto a sweaty face. Blot first, or it will not sit evenly.
- Treating water-resistant as waterproof. After heavy rain or an hour of sweating, you must reapply.
- Forcing a heavy cream sunscreen. If it feels sticky, you will end up skipping it. Switch to a light texture.
- Applying only once in the morning. If you are outside all day, that layer is gone before lunch.
When to see a doctor
If a sunscreen keeps causing stinging, redness or itching, stop using it and try a different formula. See a dermatologist if small itchy bumps keep spreading on your face or body after sweat and sun, or if you get rashes easily in sunlight.

Frequently asked questions
Where can I buy an original water-resistant sunscreen in Bangladesh for monsoon?
Buy from a seller who can show the importer's invoice and batch number for the product. This matters because a fake sunscreen may not actually hold up against sweat or water.
What should sensitive skin look for in a sweat-resistant sunscreen?
Look for a fragrance-free, mineral or centella-based formula, which tends to feel calmer on skin that sweats through the day. Patch-test any new sunscreen on a small area before full use.
How can I tell if a sunscreen is genuine?
Match the batch code on the tube with the one on the box and check that the seal hasn't been opened. An unusually heavy white cast or a texture that feels different from what you expect is worth noting too.
