Blackheads 101: What They Are, Why They Happen, and How to Prevent Them
Blackheads can feel impossible to shift, especially when they keep coming back in the same spots (hello, nose and chin). The good news is that blackheads are one of the most manageable skin concerns once you understand what’s actually happening in your pores.
Let’s break down what blackheads are, the biggest causes, the mistakes that make them worse, and the ingredients that truly help you keep pores clear and skin smooth.
Build a routine that keeps your pores clean, your skin barrier calm, and your oil production balanced — without harsh scrubbing.
Shop SkincareWhat Are Blackheads?
Blackheads are small, dark bumps that form when pores become clogged with a mix of excess oil, dead skin cells, and debris. They’re classified as a type of acne called open comedones.
The “black” colour isn’t dirt — it happens when the clogged material is exposed to air and oxidises, which darkens the surface of the plug.
Blackhead = open pore clog + oxidation. Not a hygiene issue. Not “dirty skin.”
Causes and Factors Contributing to Blackheads
Blackheads usually form when oil production is high and skin cell build-up isn’t being removed efficiently. Here are the most common contributors:
- Excess sebum (oil): When oil mixes with dead skin cells, pores clog more easily.
- Hormonal changes: Puberty, menstruation, stress, and hormonal shifts can increase oil production.
- Inconsistent cleansing: Not removing sunscreen, makeup, or pollution build-up can contribute to congestion.
- Comedogenic products: Some heavy oils, occlusive makeup, or pore-clogging formulas can worsen blackheads.
- Environmental factors: Pollution and humidity can increase oiliness and debris on the skin.
- Genetics + medication: Some people are simply more prone due to skin type or specific treatments.
You don’t want to “strip” oil — you want to balance it and keep pores consistently clear.
Common Mistakes in Blackhead Removal
Many blackhead “quick fixes” do more harm than good. Here are the big ones to avoid:
Squeezing and picking
Using fingers or unsanitised tools can push bacteria deeper, cause inflammation, and increase the risk of scarring.
Harsh scrubs and over-exfoliating
Aggressive scrubbing can damage your skin barrier, leading to irritation — and sometimes even more oil production.
Using pore-clogging products
Heavy, comedogenic skincare or makeup can keep the cycle going. Always check for “non-comedogenic” where possible.
If your skin feels raw, tight, or stings when applying products — that’s usually a sign you’re doing too much.
7 Tips for Preventing Blackheads
Prevention is the fastest way to see long-term improvement. These habits keep pores clearer and reduce new blackheads over time:
- Cleanse twice a day: Use a gentle cleanser to remove oil, dirt, and buildup without stripping your skin.
- Exfoliate regularly (but gently): Chemical exfoliants like BHA or AHA help keep pores clear.
- Avoid touching your face: Hands transfer bacteria and debris that can contribute to clogged pores.
- Choose non-comedogenic products: Look for “non-comedogenic” or “oil-free,” especially for makeup and sunscreen.
- Keep hair off your face: Hair oils and products can transfer to the skin and worsen congestion.
- Wear sunscreen daily: UV damage can worsen oil imbalance and inflammation — SPF helps protect and stabilise skin.
- Go easy on heavy makeup: Choose breathable formulas and always remove makeup thoroughly before bed.
Most routines need 4–8 weeks to show noticeable changes. Keep it simple, and stick with it.
Skincare Products and Ingredients to Combat Blackheads
The right ingredients can make a huge difference — especially those that clear pores, regulate oil, and support healthy cell turnover. Here are the most effective options to look for:
Salicylic Acid (BHA)
Oil-soluble and ideal for blackheads. It helps unclog pores from the inside, reduces inflammation, and helps prevent new congestion.
Glycolic Acid (AHA)
Great for smoothing texture and removing dead skin build-up on the surface. Glycolic acid can help pores look clearer and skin look brighter over time.
Retinoids (Retinol / Tretinoin)
Encourages cell turnover and helps keep pores from clogging. Start low and slow, and always use SPF daily.
Charcoal-based products
Helps absorb excess oil and lift impurities. Useful in masks or cleansers — especially if you feel extra congested.
Niacinamide
Helps regulate oil, calm inflammation, and support the skin barrier — all helpful for reducing blackhead formation over time.
Don’t introduce BHA, AHA, and retinoids all at once. Start with one active, use it consistently, then add more only if your skin is happy.
Professional Treatments for Stubborn Blackheads
If at-home routines and over-the-counter products aren’t giving you the results you want, professional treatments can help — especially for deeply congested pores or persistent blackheads.
Extractions
Manual removal with professional tools. Best done by a trained expert to reduce infection and scarring risk.
Chemical peels
Uses AHAs/BHAs to exfoliate more deeply, unclog pores, and improve texture and tone. Often done as a series.
Microdermabrasion
A non-invasive exfoliation treatment that smooths texture and helps reduce surface congestion over multiple sessions.
Laser / IPL
Targets oil glands and inflammation, which can reduce congestion over time. A dermatologist can advise if you’re a good candidate.
If blackheads are persistent, painful, inflamed, or affecting your confidence, a dermatologist or qualified aesthetician can guide you safely.
Key Takeaway
Blackheads are common, but they’re not unbeatable. The most effective approach is a consistent routine that keeps pores clear without damaging your skin barrier: gentle cleansing, smart exfoliation (BHA/AHA), oil-balancing ingredients like niacinamide, and daily SPF.
Avoid squeezing and harsh scrubs, be patient with results, and if congestion is stubborn, consider professional treatments. With the right strategy, you can support a clearer, smoother, more radiant-looking complexion over time.
