Quick answer
Winter sun feels mild, and Dhaka haze looks like cover. Neither stops the UV that causes pigmentation and ageing.

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 year-round.
1. Dhaka's winter haze is not sunscreen
Smog scatters light; it does not absorb UVA meaningfully.
2. Melasma worsens without winter protection
If you are treating dark spots, stopping sunscreen in winter undoes months of work.
3. You can switch texture, not skip
A cream or hydrating sunscreen suits dry winter skin better than a matte gel.
4. Indoors near a window still counts
UVA passes through glass.
5. Reapply only when outdoors
If you are inside all day, one morning application is reasonable.
