The best serum for open pores in Bangladesh is one that combines niacinamide with a gentle exfoliant, and the pick Orpa stocks is The Derma Co Pore Minimizing Serum at ৳1,190, made with 4% niacinamide and 5% PHA. If your pores look big because they are full of blackheads, a BHA liquid such as COSRX’s at ৳1,000 does more. No product closes pores permanently, but the right one makes them look noticeably smaller.
This guide compares five leave-on serums for open pores, because a product that stays on the skin does far more than a face wash that rinses off in a minute. It then covers the one wash, one mask and one sunscreen worth pairing with them, and which pore myths to ignore.

Why pores look open, and what can change
A pore is the opening of a hair follicle with an oil gland attached. You cannot close it or remove it, and anything that promises to is overselling. What makes pores look larger is usually one of three things:
- Oil: heavy sebum stretches the opening and makes it shine, which is why pores look biggest on the nose, forehead and inner cheeks.
- Clogging: dead skin and oil packed into the pore turn dark at the surface as blackheads, and a filled pore looks bigger than an empty one.
- Loose skin around the pore: with age and years of sun, the collagen that holds the pore tight weakens, so pores on the cheeks start to look long and oval.
Each cause has a different fix. Niacinamide works on oil, BHA clears the clogging, and retinoids plus daily sunscreen work on the skin around the pore. That is why the five serums below are sorted by cause, not by brand.
Blackheads or sebaceous filaments?
Many people squeeze grey dots on their nose that are not blackheads at all. Sebaceous filaments are normal, pale grey, evenly spaced and refill within days of being squeezed. True blackheads are darker, raised slightly and scattered unevenly. Filaments can be made less visible with BHA and niacinamide, but they will always come back, so squeezing them only damages the pore and makes it look larger over time.
The five, in detail
The Derma Co Pore Minimizing Face Serum, 30 ml — ৳1,190
The all-round pick. It combines 4% niacinamide to control oil, 5% PHA as a mild exfoliant and p-Refinyl, an ingredient marketed specifically for pore appearance. It is lightweight and fragrance-free, so it suits most oily and combination skin twice a day. See the product page.
COSRX BHA Blackhead Power Liquid, 50 ml — ৳1,000
For pores that look big because they are full. A leave-on BHA exfoliant, which is oil-soluble and works inside the pore to loosen blackheads and the grey plugs on the nose. Use it at night, three times a week to start. It is also the best value per millilitre of the five. See the product page.
SKIN1004 Madagascar Centella Poremizing Fresh Ampoule, 30 ml — ৳850
For pores on skin that reddens or stings easily. Centella calms, and the water-light ampoule helps balance oil without an acid. It is the gentlest of the five and the cheapest bottle, and it layers well under a moisturizer morning and night. See the product page.
Minimalist 10% Niacinamide Face Serum, 30 ml — ৳1,440
For pores driven mainly by oil. Ten percent niacinamide is a strong dose for sebum control, and less oil means pores that look smaller and less shiny by midday. Give it four to eight weeks. If it stings, alternate days or switch to the 4% Derma Co serum above. See the product page.
Numbuzin No. 3 Blue Bio-Retinol Pore Refining Serum, 30 ml — ৳1,790
For stretched, oval pores on the cheeks and rough texture, usually from the late twenties onward. It pairs a bio-retinol with 10% niacinamide, so it works on the skin around the pore over months rather than weeks. Use it at night only, and keep other exfoliants to separate nights. See the product page.
What to pair with the serum
- Wash: Anua Heartleaf Quercetinol Pore Deep Cleansing Foam, 150 ml at ৳1,390, a gentle foam for oily and acne-prone skin. For cheaper options, see the face wash for oily, acne-prone skin guide.
- Mask, once or twice a week: Dot & Key Cica & Salicylic French Green Clay Mask, 85 g at ৳1,370. Clay lifts surface oil for a day or two; it is a boost, not a treatment.
- Sunscreen, every morning: The Derma Co Pore Minimizing Priming Sunscreen SPF 50 at ৳790 blurs pores under makeup and, more importantly, protects the collagen around them. The sunscreen guide has more.
- Moisturizer: a light oil-free gel. The moisturizer for oily skin guide compares five.
Pore myths to ignore
- Ice or cold water closes pores. Cold briefly tightens skin for a few minutes; the pore itself does not change.
- Steam opens pores. Pores do not open and close like doors. Steam softens what is inside, which is why facials use it before extraction.
- Pore strips fix blackheads. They pull out the top of the plug and some skin with it. The pore refills within days.
- Toner shrinks pores. Alcohol toners make skin feel tight, then strip it, which can mean more oil later.
- Scrubbing harder helps. Rough scrubs irritate and inflame the skin around the pore, which makes it look bigger.
How to use pore serums without irritation
- Use one exfoliating product at a time. Do not stack BHA, PHA and retinol on the same night.
- A simple split: niacinamide or centella in the morning, BHA or retinol at night on alternate nights.
- Apply to dry skin, a few drops for the whole face, then moisturizer.
- Expect four weeks for less oil and shine, and three months for texture changes from retinol.
- Stop any product that causes burning, swelling or peeling that does not settle in a few days.
Deep, stretched pores or pitted acne scars do not respond much to serums. Dermatologists treat those with procedures such as chemical peels, microneedling or lasers.
Frequently asked questions
Which serum is best for open pores in Bangladesh?
The Derma Co Pore Minimizing Serum at ৳1,190 for most people. For pores clogged with blackheads, COSRX BHA Blackhead Power Liquid at ৳1,000.
Which face wash is best for open pores?
A gentle foam that does not strip, such as Anua Heartleaf Pore Deep Cleansing Foam at ৳1,390. A wash matters less than the serum, because it is rinsed off within a minute.
Can open pores be closed permanently?
No. Pores can be made to look smaller by reducing oil, clearing blockages and protecting the surrounding skin from sun, but they cannot be closed.
Is niacinamide or salicylic acid better for pores?
Salicylic acid, a BHA, for blackheads and clogging. Niacinamide for oiliness. Many people use both at different times of day.
How long does it take to see smaller pores?
About four weeks for less shine and cleaner pores, and around three months for texture changes from retinol.
Are open pores worse in summer?
Usually yes. Heat and humidity increase oil production, which is why a lighter moisturizer and a niacinamide serum help most from June to September.
Do pores get bigger with age?
They tend to look bigger, mainly on the cheeks. Collagen around the pore weakens with age and sun exposure, so the opening sags and stretches. Daily sunscreen from your twenties and a retinoid at night are the two habits that slow it down most.
Should I get pores extracted at a salon?
Occasional professional extraction of true blackheads is fine. Frequent squeezing, at a salon or at home, stretches and inflames the pore, which is the opposite of what you want.
Are these products original?
Yes. Orpa imports them in sealed manufacturer packaging with the original label and batch code intact. Delivery is ৳70 inside Dhaka City in 1 to 3 days and ৳120 elsewhere in Bangladesh in 2 to 4 days, with cash on delivery nationwide.
This guide is general information about products Orpa sells, not medical advice. Patch test new actives on your jaw for two nights first, and avoid retinol products if you are pregnant or breastfeeding. Prices and stock were correct on 21 September 2026 and change over time.
