Blackhead Treatment in Ho Chi Minh City: Clearing Open Comedones Safely

Medically reviewed by Dr Quynh Trang, Dermatologist (HCMC) · Updated August 1, 2026

## Do blackheads go away on their own?

Almost never — and waiting is the part that costs you. A blackhead is an open comedone: a plug of sebum and keratin wedged in the neck of the follicle, with the pore still open so the exposed tip oxidizes and darkens. Your skin has no mechanism for pushing that plug out, so what actually clears it is removal — extraction through a softened, dilated pore, with medical peels to loosen the keratin that traps the next one. At WeDo Skin Clinic (District 1 and District 2, HCMC), a board-certified dermatologist examines your skin under multi-layer analysis free of charge, then builds the plan: extraction with barrier recovery from 760,000 VND per session, medical peels 790,000–1,500,000 VND per session, IPL for oil and bacterial control 370,000 VND per session.

Most people wait because blackheads feel minor. They don’t hurt, they don’t swell, and they read as a cosmetic nuisance rather than a condition. But mild symptoms are not the same as temporary. The plug inside the follicle has been compacted over weeks and adheres to the follicular wall — your skin sheds the surface layer daily, but nothing inside the follicle is part of that cycle.

The second reason blackheads persist is mechanical. A plug sitting in a follicle holds the opening dilated, like a wedge. The longer it stays, the more the elastic tissue around that opening loses its ability to spring back — which is why a comedone extracted after many months often leaves a pore that reads larger than it did before. That, not the color, is the argument for treating early. For a broader look at how non-inflamed lesions form and behave, see what causes non-inflammatory acne; for the full range of acne protocols we run, start from medical acne treatment at WeDo.

## Why are blackheads black? The open-comedone mechanism

Four steps, and knowing them explains why almost every home method misses.

First, the follicular neck becomes hyperkeratinized: keratinocytes shed faster than normal and stick together instead of falling away. Second, the sebaceous gland keeps producing at its usual rate while the exit route narrows, so sebum accumulates behind the obstruction. Third, keratin and sebum compact into a dense plug — but unlike a closed comedone, the pore here stays open. Fourth, because the pore is open, the exposed head of the plug meets air: melanin in the keratin and lipids in the sebum oxidize, and that surface darkens from brown to black.

So the color is not dirt. This is the most expensive misconception in the category, because it leads straight to the wrong behavior — washing more often, scrubbing with grit, running a cleansing brush every night. None of that reaches a plug sitting inside the follicle, and all of it erodes the barrier at the surface. Skin gets tight and dehydrated, sebum production compensates upward, and you have created the conditions for the next crop. A related myth worth clearing up separately: whether a blackhead can turn into a mole.

### How open comedones differ from closed ones

An open comedone has an exit, so the head of the plug is exposed and oxidizes; a closed comedone is sealed under keratin, keeps its skin color, and is felt rather than seen — that lesion type is covered on our hidden acne treatment page, since it needs a different approach.

### Blackheads on the nose: why the T-zone gets the most

Three local factors stack up. Sebaceous gland density is highest on the nose, alar creases and forehead, so more sebum drains into each follicle there than on the cheeks. The stratum corneum is also thicker across that zone, which makes the follicular neck easier to block. And it is the area with the most contact with foundation and heavier-textured sunscreen — products that settle into the alar creases when evening cleansing is done in a hurry.

Worth saying plainly: not every dot on your nose is a comedone. Sebaceous filaments are evenly distributed, tiny, light gray, and a normal part of follicular anatomy; blackheads sit unevenly, protrude, and have a distinctly dark head. Squeezing a sebaceous filament doesn’t remove it, because it was never a plug to begin with.

## Why squeezing and pore strips make pores look bigger

The real question is not whether open comedones can be extracted — they can, and they are the lesion type most suited to extraction. The question is with what force, at what moment, with what instrument. Those three variables decide whether the area looks smoother afterward or worse. If you are wondering where the line sits generally, we cover when acne should and shouldn’t be extracted separately.

### Squeezing with fingers or a non-sterile tool

Two fingertips press inward from the sides, generating lateral force, while the plug sits along the axis of the follicle. The result splits almost every time: the head lifts out and you feel successful, and the body of the plug is driven deeper than where it started. If the pressure is high enough, a follicular wall already thinned by months of wedging can tear, releasing sebum and bacteria into surrounding tissue — a reliable way to turn a non-inflamed open comedone into a red, tender papule.

The second problem is sterility. Fingernails, an unsterilized extraction tool and a bathroom counter all introduce bacteria into a pore that is open and has just been traumatized. That is why a spot that was “only a dark dot” last night is a sore red bump by morning.

### Do pore strips actually remove blackheads?

A pore strip works by vertical traction: adhesive grips the hardened head protruding from the pore and pulls it upward. Something genuinely comes out — but it is the tip of the plug, not the plug. The body remains in the follicle, its newly exposed surface oxidizes, and the nose is clear for a few days before it looks exactly as it did before. That is the loop people describe as clean for one evening, then back to normal.

The cost sits in the fact that traction cannot distinguish a comedone from healthy stratum corneum. Repeated stripping takes the protective layer with it: dry, red skin that stings under products you have used for years, followed by compensatory oil. A pore held under repeated traction also loses elasticity, and that is the practical route from “blackheads on my nose” to “large pores on my nose.” Our detailed breakdown sits on blackhead removal on the nose.

### When a blackhead turns into inflamed acne

Once the plug is driven deeper and the follicular wall is damaged, the sealed low-oxygen space beneath becomes favorable for resident skin bacteria to multiply, and the lesion becomes a red, tender papule. From that point the priority is no longer extraction but calming the inflammation, which is what inflammatory acne treatment addresses; if the inflammation goes deeper and consolidates into firm nodules, that is cystic acne with its own protocol.

So what does correct extraction change? The order of operations. The keratin sealing the follicular neck is softened and the pore dilated first, and only then is the plug brought out along the follicular axis with sterile instruments — and only the plugs that are ready. That procedure is medical acne extraction. The softening step is usually done with a medical peel, because BHA (salicylic acid) is oil-soluble and can penetrate the sebum plug itself rather than acting only on the surface.

Depending on your skin, your dermatologist may add IPL where skin is oily and inflames easily or still carries post-acne marks, and hydration electrophoresis to deliver soothing actives into the superficial layer straight after extraction. Every device behind these steps is listed in our treatment technology overview. Individual prices are in the table below, the complete list of every service we offer is on the WeDo price list, and how these line items combine into a full acne course is set out separately on acne treatment cost. The sequence of exam, treatment and review is the same across all our services and is described in WeDo’s treatment journey.

Visiting or living in HCMC short-term? Our dermatologists consult in English, and both clinics — District 1 and District 2 — run the same protocols. An extraction session with a light peel leaves no crusting and no visible downtime, so it fits comfortably a day or two before a flight; heavier peels are planned differently and we will say so at the exam. The first consultation and skin analysis cost nothing, so it is a reasonable first stop even if you only want to know whether those dots are comedones or sebaceous filaments — book a free consultation.
