Whiteheads and blackheads are two of the most common types of acne, and because both develop from clogged hair follicles, they can be easy to confuse. The important difference is what happens at the opening of the clogged follicle. A whitehead is a closed comedone, while a blackhead is an open comedone.
That small difference explains much of what you see on the skin. Whiteheads usually appear as small white or flesh-colored bumps, while blackheads look like dark spots. Despite their different appearance, both are forms of comedonal acne and can often be managed with similar approaches.
Quick Answer
Whiteheads are closed clogged pores, while blackheads are open clogged pores.
A whitehead forms when oil and dead skin cells clog a follicle but the opening remains closed. A blackhead forms when the clogged follicle remains open, allowing the material inside to interact with air and appear dark.
The key point is that blackheads are not simply dirt trapped in your skin. Their dark appearance is related to the contents of the open follicle and changes that occur when it is exposed to air.
Whiteheads vs. Blackheads at a Glance

Whiteheads and blackheads are both recognized as acne lesions, and both are generally classified as comedones.
What Is a Whitehead?
A whitehead is a clogged hair follicle whose opening is closed.
When excess oil and dead skin cells build up inside a follicle, they can form a small raised bump. Because the opening remains closed, the contents do not have the same exposure to air as an open comedone.
This produces the familiar small white or flesh-colored bump associated with a whitehead.
The medical term for a whitehead is closed comedone.
Whiteheads commonly appear on areas such as:
- Forehead
- Nose
- Chin
- Cheeks
- Chest
- Back
They may be more noticeable when many small bumps appear together.
Example
She has several small whiteheads across her forehead.
Here, “whiteheads” refers to closed, clogged follicles rather than inflamed pimples.
What Is a Blackhead?
A blackhead is a clogged hair follicle whose opening remains open.
Like whiteheads, blackheads develop when material such as sebum and dead skin cells accumulates inside a follicle. The important difference is that the follicle remains open at the skin’s surface.
The medical term for a blackhead is open comedone.
Blackheads often appear as:
- Small dark dots
- Dark spots on the nose
- Black or gray-looking plugs
- Slightly raised or relatively flat clogged pores
Example
He noticed several blackheads around his nose.
The dark appearance does not mean that the pore is filled with dirt.
What Is the Main Difference Between Whiteheads and Blackheads?
The simplest way to remember the difference is:
Whitehead = closed.
Blackhead = open.
Both begin with a clogged follicle. The difference is what happens to the follicular opening.
With a whitehead, the opening is closed, producing a white or flesh-colored bump.
With a blackhead, the opening remains open. The material inside the follicle becomes dark-looking, producing the characteristic black or dark spot.
So the difference is not that one contains “clean” material and the other contains dirt. Both are related to clogged follicles.
Why Do Blackheads Look Black?
This is one of the most common misunderstandings about blackheads.
A blackhead may look as though dirt has accumulated inside a pore, but blackheads are not caused simply by dirt. The dark appearance is associated with the contents of an open follicle and their exposure to air.
This is why aggressive scrubbing is not the solution. Scrubbing harder does not simply “wash away” a blackhead and can irritate acne-prone skin. The American Academy of Dermatology specifically advises against treating blackheads as dirt that needs to be scrubbed away.
What Causes Whiteheads and Blackheads?
Whiteheads and blackheads share many of the same underlying causes.
Acne develops when hair follicles become clogged with substances such as sebum and dead skin cells. Hormonal changes, increased oil production and other factors can contribute to acne development.
The basic process can be simplified as:
Excess oil + dead skin cells → clogged follicle → comedone
The follicle’s opening then helps determine what type of comedone develops:
Closed opening → whitehead
Open opening → blackhead
Both are generally considered forms of noninflammatory acne, unlike papules, pustules, nodules and cysts, which involve inflammation.
When to Treat Whiteheads
Whiteheads may respond to acne treatments designed to prevent or clear clogged pores.
Dermatologists may recommend treatments such as topical retinoids, including adapalene, because retinoids help clear pores and can treat whiteheads and blackheads. Salicylic acid is another commonly used acne ingredient that can help unclog pores.
For mild acne, consistent treatment is generally more useful than repeatedly squeezing individual whiteheads.
If whiteheads persist, become extensive, or are accompanied by other forms of acne, a dermatologist can help determine the appropriate treatment.
When to Treat Blackheads
Blackheads also respond to treatments that target clogged pores.
The American Academy of Dermatology identifies retinoids as an option for treating blackheads, while salicylic acid can help unclog pores and is particularly useful for whiteheads and blackheads.
Avoid trying to force a blackhead out with your fingernails. Squeezing or picking can irritate the skin and may increase the risk of infection, inflammation or scarring.
For stubborn blackheads that do not respond to appropriate treatment, professional comedone extraction may be an option.
Can the Same Treatment Help Whiteheads and Blackheads?
Often, yes.
Because both conditions involve clogged follicles, their treatment can overlap considerably.
Commonly used acne treatments include:
Salicylic Acid
Salicylic acid helps unclog pores and exfoliate the skin. The AAD specifically notes that it works well for whiteheads and blackheads.
Adapalene
Adapalene is a topical retinoid that helps clear clogged pores and can treat blackheads and whiteheads.
Benzoyl Peroxide
Benzoyl peroxide is another established acne treatment. It can reduce acne-causing bacteria and is used in acne treatment plans, although treatment should be selected according to the type and severity of acne.
Professional Treatment
A dermatologist can perform comedone extraction when appropriate, particularly when whiteheads or blackheads remain stubborn despite other treatment.
Treatment results are not usually immediate. Dermatology sources note that acne treatments often require several weeks of consistent use before improvement becomes clear.
Common Mistakes With Whiteheads and Blackheads
Mistake 1: Thinking blackheads are dirt
Incorrect idea:
“My pores are black because they’re full of dirt.”
Better understanding:
Blackheads are open comedones, and their dark appearance is not simply dirt.
Mistake 2: Scrubbing harder
Incorrect:
“If I scrub my nose harder, the blackheads will disappear.”
Correct:
Use appropriate acne treatment rather than aggressive scrubbing.
Excessive washing and scrubbing can irritate acne-prone skin and potentially make breakouts worse.
Mistake 3: Squeezing every whitehead
Incorrect:
“I should pop every whitehead as soon as I see it.”
Correct:
Treat the acne rather than repeatedly picking at individual lesions.
Picking whiteheads can contribute to additional acne and scarring.
Mistake 4: Assuming every dark pore is a blackhead
Not every small dark-looking pore on the nose is necessarily a blackhead. Sebaceous filaments can also appear as tiny dots and are a normal feature of many pores.
Whiteheads, Blackheads and Sebaceous Filaments
This distinction is especially useful when looking closely at the nose.
A blackhead is an open comedone associated with acne.
A sebaceous filament is a normal structure associated with the movement of sebum through a pore. It may look like a small gray, yellowish or dark dot, especially on the nose.
Because they can look similar, people sometimes mistake sebaceous filaments for blackheads.
That means repeatedly squeezing tiny dots from your nose may not solve the problem you think it will.
Are Whiteheads and Blackheads Interchangeable?
No.
The terms describe different types of comedones.
- Whitehead = closed comedone
- Blackhead = open comedone
However, they are closely related because both result from clogged hair follicles and are forms of comedonal acne.
Their treatments can overlap, so “different” does not necessarily mean that they require completely separate skincare routines.
How to Remember the Difference
Use this simple rule:
Whitehead = closed. Blackhead = open.
You can also remember it this way:
Whitehead: the clog stays covered.
Blackhead: the clog is exposed through an open follicle.
The word “black” does not mean dirt.
Which One Should I Use?
If you’re trying to identify what you see on your skin:
Small white or flesh-colored raised bump → likely a whitehead
Dark spot or dark plug in an open pore → likely a blackhead
Tiny uniform dots, especially on the nose, that may resemble normal pore contents → could be sebaceous filaments
Red, swollen or painful bump → may be another type of acne rather than a simple comedone
If you’re uncertain about a persistent or unusual skin lesion, a dermatologist can make a more reliable diagnosis.

Frequently Asked Questions
What is the main difference between whiteheads and blackheads?
The main difference is the condition of the follicular opening. Whiteheads are closed comedones, while blackheads are open comedones. Both result from clogged hair follicles.
Are whiteheads and blackheads the same thing?
No. They are different types of comedones, but they share the same general underlying problem: a clogged hair follicle.
Are blackheads actually dirt?
No. Blackheads are not simply dirt trapped inside the skin. Their dark appearance is associated with the material in an open clogged follicle and its exposure to air.
Which is worse, whiteheads or blackheads?
Neither is automatically “worse.” Both are generally noninflammatory forms of acne. The severity of acne depends on factors such as the number and type of lesions and whether inflammatory or deeper lesions are also present.
Can whiteheads and blackheads be treated with the same products?
Often, yes. Treatments that target clogged pores, including salicylic acid and topical retinoids such as adapalene, can be useful for both. The appropriate treatment depends on the person’s skin and acne severity.
Should I squeeze blackheads?
It is generally better not to squeeze or pick them yourself. Picking can irritate the skin and increase the risk of scarring or other complications. Professional extraction may be appropriate for persistent comedones.
Should I pop whiteheads?
Avoid routinely picking or popping whiteheads. Dermatologists recommend treating whiteheads rather than picking them because picking can contribute to acne and scarring.
What ingredient is useful for both whiteheads and blackheads?
Salicylic acid can help unclog pores and is specifically noted by the AAD as useful for whiteheads and blackheads. Topical retinoids such as adapalene can also clear clogged pores.
When should I see a dermatologist?
Consider professional advice if acne is persistent, severe, painful, scarring, or not improving with appropriate over-the-counter treatment. Dermatologists can recommend stronger treatments or procedures such as comedone extraction when appropriate.
Conclusion
Whiteheads and blackheads are closely related forms of acne, but they are not identical. A whitehead is a closed comedone, while a blackhead is an open comedone. Both develop when hair follicles become clogged, but the condition of the follicular opening produces their different appearances.
The easiest rule to remember is:
Closed = whitehead. Open = blackhead.
