Oily skin benefits from a lightweight, water-based serum that balances oil and refines pores — not a heavy, occlusive one. Full routine: the oily-skin routine. Here is what to look for.
Best ingredients
- Niacinamide — the #1 for oily skin: regulates oil, minimises pores, evens tone. See best niacinamide.
- Salicylic acid (BHA) — keeps pores clear, reduces blackheads. See BHA and blackheads.
- Zinc (often with niacinamide) — helps oil control.
- Hyaluronic acid — light hydration so skin does not over-produce oil. See HA.
- Vitamin C (AM) — brightening + antioxidant, lightweight formulas.
What to skip
- Heavy oil-based or thick "nourishing" serums — too rich for oily skin in humidity.
- Do not skip hydration thinking it will "dry out" the oil — dehydrated oily skin makes *more* oil.

Frequently asked questions
Where can I buy a genuine niacinamide serum for oily skin in Bangladesh?
Buy from a seller who can show the importer's invoice and batch number for that serum. TheSkinProof matches every serum against the importer's invoice and batch before it is listed.
How do I check if a niacinamide serum bottle is authentic?
Compare the batch code on the bottle with the one on the box and check that the dropper seal is unbroken before you start using it. If the serum looks unusually thick, watery, or yellowed and causes more irritation than expected, stop using it.
What differences show up between a genuine and a fake serum?
A fake serum often has a mismatched batch code, a loose or missing dropper seal, and a texture or color that is noticeably off from a genuine bottle. Unexpected irritation compared to a product you have used before is another red flag.
