Blackheads: What Causes Them and When to See a Dermatologist

Blackheads are a type of acne that occurs when pores or follicles become clogged with excess oil, dead skin cells, and bacteria. Visually, a blackhead might look like dirt is trapped on its surface, but the dark color is due to how light reflects off the blocked pore. Blackheads are especially common among young adults and people with oily or acne-prone skin, but they can affect everyone, irrespective of their age and skin type. Blackheads, if left untreated, can lead to enlarged pores, uneven skin texture, and, in severe cases, more inflamed breakouts.

This detailed guide talks about what blackheads are and why they form, where they appear, and how to treat them using dermatologist-approved methods.

What are Blackheads?

Blackheads, also known as open comedones, are a type of non-inflammatory acne lesion. They are blocked pores which are filled with dead skin cells and sebum (oil). Unlike whiteheads, they are formed on the surface of the skin and appear black.

Why They Look Black

The dark color of a blackhead isn’t dirt. They look black because of a chemical reaction called oxidation that occurs under your skin. When the melanin in the trapped sebum and dead skin cells reacts with air, it oxidizes and changes into a black or dark gray color. This is why they are called blackheads.

Difference Between Blackheads, Whiteheads, and Pimples

While all three are types of acne, here’s how they are different:

• Blackheads are open pores on the skin surface filled with oil and dead skin cells, which get oxidized, giving them a dark color.
• Whiteheads are closed pores below the skin's surface, and they appear white or flesh-colored.
• Pimples are inflamed or infected bumps, sometimes filled with pus.

Who Gets Blackheads and How Common Are They?

Here is who can get blackheads:

Age Groups and Skin Types Affected

Blackheads can affect people of all ages and skin types. However, they are more common in teenagers undergoing physical, emotional, and behavioral changes during puberty, as well as in young adults and people with oily or combination skin.

Conditions That Make Blackheads More Likely

Certain health and lifestyle conditions increase the chances of blackheads. These include:

• Hormonal imbalance in situations like Polycystic Ovary Syndrome (PCOS), puberty, and menstruation in women
• More sebum/oil production in oily skin type
• Skincare or makeup that is comedogenic or pore-clogging
• Poor face cleansing

How Common are Blackheads?

Blackheads are a very common skin condition, and most people experience them at some point in their lives. As per the American Academy of Dermatology (AAD), approximately 85% of people aged between 12 and 24 years can experience at least some kind of minor acne.

Where Do Blackheads Commonly Appear?

Since the face has the largest amount of sebaceous (oil) glands in the body, certain areas on the face are more prone to clogged pores and blackheads.

Blackheads on Face

• The nose is one of the most common areas.

Others include the chin, forehead, and cheeks, especially if a person has large pores or oily skin.

Body Areas

Include chest, back, shoulders, and ears.

What are the Symptoms of Blackheads?

Blackheads are easy to spot because of their distinct black color. Here are some common symptoms:

Visible Symptoms

• They appear as small and dark spots or bumps.
• Pores may look visibly open or enlarged.

Skin Texture Changes

• Rough or uneven skin texture.
• Blackheads feel like slightly raised bumps on the skin.

Blackheads can also create a psychological Impact, like:

• Having blackheads can cause lower self-esteem or confidence.
• A person might develop a skin-picking habit due to a constant urge to pick or squeeze blackheads, which can cause scars and infections.
• A person may feel anxious about how they look.

What Causes Blackheads?

Here are some other causes of blackheads:

• Dead Skin Cell Accumulation

If dead skin cells don't shed properly and accumulate in the pores, it can lead to cell buildup and blocked pores, which can then cause blackheads.

• Hormonal Imbalances (Puberty, Menstruation, PCOS)

Androgen is a hormone that can cause blackheads as it helps stimulate oil production, which then clogs the pores. This hormone fluctuation is common during puberty, menstruation, or conditions like PCOS.

• Comedogenic Skincare or Makeup

Some heavy skincare and makeup that contain ingredients like specific oils and silicones can clog pores, eventually leading to blackhead formation. Particularly, blackheads on the cheeks occur if you don’t remove makeup well or sleep with makeup on.

• External Factors (Pollution, Humidity, Sweat)

Environmental factors like dust and sweat can also add to the congestion of pores, especially in places with high humidity.

• Inadequate or Irregular Skincare Habits

Harmful skincare habits like not washing your face well or over-washing can lead to clogged pores and also cause an imbalance. Not cleaning your face allows oil and dirt to build up in the pores, causing blackheads. On the other hand, over-washing makes your skin dry and strips it of its natural oils, prompting your body to produce more oil, which can eventually lead to blackheads.

• Genetics and Stress

A family history of acne or high stress levels may increase sebum production, leading to blackheads.

Are Blackheads Contagious?

Since bacteria or viruses do not cause blackheads, they cannot be passed from one person to another through contact or otherwise. They are a result of how your internal skin reacts and not from infection or poor hygiene.

Sometimes, blackheads come in clusters, and sudden outbreaks across certain areas of the skin can lead many to believe that they are contagious.

Having good hygiene and a skin routine can help prevent blackheads. They occur because of a host of internal factors, such as excess sebum production and hormonal fluctuations.

How are Blackheads Diagnosed?

Here’s how blackheads are diagnosed:

Dermatologist Visual Examination

Due to their typical dark spot-like appearance, a dermatologist can diagnose blackheads through a visual examination.

Skin History and Product Use Assessment

Learning about your skincare routine, the products you use, medical history, and lifestyle habits makes it easy for a specialist to understand what’s causing blackheads.

Use of Tools

Your dermatologist might use devices like magnifying lamps or digital skin analyzers to evaluate pore congestion and skin type in detail.

How are Blackheads Treated?

Blackheads can be treated in many ways, such as:

Topical OTC Products

Most blackhead and acne medications are available over-the-counter in the form of creams and gels. Some of the ingredients used in these medications are:

• Salicylic Acid (BHA): This penetrates the pores and dissolves the oils and dead skin, which can help prevent pore clogging.
• Retinoids (Adapalene, Retinol): These help break the blackheads and prevent congestion of pores.
• Benzoyl Peroxide: This ingredient targets bacteria that can cause acne.

Professional Procedures

A trained aesthetician or a dermatologist can remove blackheads with the help of these procedures:

• Manual extraction can be done with the help of a special tool called a round loop extractor, which removes the dead skin/oil plug present at the surface.
• Chemical peels with glycolic, lactic, or salicylic acid help remove clogged pores and dead skin, which can cause blackheads.
• Microdermabrasion can be used for mechanical exfoliation. A special instrument that contains a rough surface is used to sand the top layers of the skin, which helps exfoliate and remove the congested pores.
• Laser and light therapy involve tiny beams of intense light used to decrease oil production and target blackheads.

Prescription-Strength Options

If OTC medications won't improve acne, your dermatologist might prescribe stronger medications that may need a prescription.

• Topical Tretinoin or other retinoids are stronger and can be used for deep-rooted congestion.
• Oral antibiotics can help reduce bacteria that cause blackheads.

Are There any Effective Home Remedies for Blackheads?

If you are wondering ‘how to remove blackheads naturally?’, here are some effective home remedies:

• Gentle Exfoliation (AHAs/BHAs)

Exfoliating can help remove dead cells and sebum from your skin. Using gentle exfoliants with ingredients like glycolic acid or salicylic acid can help prevent pore buildup.

• Clay or Charcoal Face Masks

Clay and charcoal can deep clean pores and remove impurities from them. However, these masks can also be too drying, so it's best to use them only 1 or 2 times a week.

• Steam Treatments

Warm steam can help loosen the dirt and oil in the pores, which can aid in better extraction of blackheads without causing irritation.

• Natural Ingredients

Essential oils like tea tree can help prevent the growth of bacteria, while aloe vera can reduce oiliness and also calm any irritation around pores. These can be used to help control blackheads, but should not replace professional treatment.

When trying out home remedies and ingredients, always conduct a patch test and consult a dermatologist if you have stubborn or worsening blackheads.

Do Blackheads Go Away on Their Own?

This depends on how deep the blackheads are in your skin:

• Mild cases may resolve over time: With increased exfoliation in your skincare routine, if a blackhead is close to the skin surface, it may go away on its own.
• Persistent cases need treatment: Deep or stubborn blackheads might need topical treatment and/or a dermatologist to remove them.

Remember, a correct and consistent routine tailored to your concerns is key to preventing new blackheads and maintaining your skin.

Is It Okay to Squeeze Out Blackheads?

While it may be satisfying to watch a blackhead pop out, squeezing a blackhead can cause more harm.

Risks of Squeezing

• It can cause irritation if you have accidentally pushed the blackhead into your skin.
• Squeezing or poking a blackhead can allow more bacteria back into the pore, which could also spread.
• It can cause hyperpigmentation or scarring.

Safer Alternatives

• You can use a sterile comedone or blackhead extractor tool instead for blackhead removal at home.
• For moderate to severe cases, an in-office extraction by dermatologists is ideal.

When to See a Dermatologist Instead

If blackheads are widespread, painful, and keep spreading and causing inflammation or distress, it's best to get them checked with a dermatologist.

How Do You Get Rid of Deep or Stubborn Blackheads?

If you have deep or stubborn blackheads, topical at-home treatments might not work. You will need:

• Medical-Grade Topicals

Prescription retinoids and tretinoin are more potent than topical over-the-counter retinoids and can help control excess oil production and treat severe cases of blackheads.

• Advanced Procedures

Specific advanced procedures like chemical peels, microdermabrasions, or laser therapy can treat severe blackheads and also prevent them from coming back.

• Addressing Internal Triggers

Treating hormonal fluctuations or diet-related symptoms and managing stress can help prevent blackheads from emerging again.

How Do You Prevent Blackheads?

Here are some simple and effective ways and habits to prevent blackheads:

Daily Skincare Routine

An effective and consistent skin care routine with the right products is the first step in preventing blackheads.

• Use a gentle cleanser and avoid over-washing your face.
• Use a lightweight and non-comedogenic moisturizer.
• A broad-spectrum and oil-free sunscreen is ideal for daily use.

Use Non-Comedogenic Products

Look for labels indicating "non-comedogenic”, which means the products are formulated to avoid blocking your pores. If you have oily or acne-prone skin, choose non-comedogenic moisturizers, sunscreens, and makeup.

Weekly Maintenance

• Using exfoliant scrubs and masks to remove dead skin can help reduce blackheads. Exfoliation should not be done more than once or twice a week.
• Clay masks can deep clean pores; use them once or twice a week.

Dietary and Lifestyle Adjustments

• Eat a well-balanced meal with whole foods, fruits, and vegetables.
• Avoid high-glycemic index foods like white bread and sugary drinks, as they can cause acne and blackheads.
• Reduce dairy if sensitive.
• Stay hydrated.
• Manage stress.

Don’t Skip Moisturizer

Even oily skin needs hydration. Use a lightweight and non-comedogenic moisturizer to balance your skin barrier.

What to Expect if You Have Blackheads

• When you follow a good routine and take care of your skin, it's easy to manage blackheads, and they can be reduced and prevented with time.
• Sometimes, blackheads can occur due to internal hormonal fluctuations and certain triggers like stress; it's important to address these issues.
• You should see a dermatologist when over-the-counter treatments aren’t working, or if your blackheads are severe, painful, or are scarring. Also, if having blackheads is affecting your confidence or mental health, it's best to ask for professional help.

Common Myths About Blackheads

There are several myths related to blackheads, such as:

• “Blackheads Are Dirt”

Blackheads are not dirt. They get their dark color due to a chemical reaction called oxidation.

• “Scrubbing Hard Will Remove Them”

Scrubbing blackheads too hard might damage your skin barrier or cause more dirt/oil to get inside the pores.

• “Only Teenagers Get Them”

While blackheads are more common in teenagers and young adults, they can appear at any age due to various factors like skin type and hormonal imbalances.

• “DIY Remedies Like Lemon or Toothpaste Work”

Lemon and toothpaste can irritate your skin and, in some cases, worsen the acne. There is no dermatological evidence that supports their use.

Frequently Asked Questions (FAQs)

1. Can diet affect blackhead formation?

Yes, diet can lead to blackhead formation in some individuals. Certain high glycemic foods and dairy products can aggravate or cause blackheads.

2. How long does it take to remove blackheads?

This depends on the severity of blackheads and consistency with your routine and treatment plan. It can range from days if you get them extracted manually to weeks or longer if you have opted for topical or prescription-based treatment.
