What Causes Acne?
Acne occurs when hair follicles become blocked by excess oil (sebum), dead skin cells, and bacteria. Hormonal changes increase sebum production, which mixes with dead skin cells and clogs pores. These blocked pores provide an ideal environment for acne-causing bacteria (Cutibacterium acnes) to grow, triggering inflammation that leads to redness, swelling, and sometimes pus-filled pimples.
Key Triggers:
- Hormonal imbalances (puberty, pregnancy, PCOS)
- Stress (raises cortisol levels, leading to increased oil production).
- Diet (high glycemic index foods, dairy)
- Skin Care Products (comedogenic ingredients).
Types of Acne
Acne is divided into two Main and subtypes:
inflammatory and non-inflammatory.
1. Non-Inflammatory Acne
Blackheads (Open Comedones):
Open clogged holes that are exposed to air and therefore oxidised (turned black).
Whiteheads (Closed Comedones):
Clogged pores that are covered by a thin layer of skin.
2. Inflammatory Acne
Papules:
Red bumps that are small and without pus.
Pustules:
Red bumps that contain white or yellow pus.
Nodules:
Bigger, painful bumps under the skin.
Cysts:
Deep lesions filled with pus that may scar.
Genetics and hormones play a role
Hormonal Acne:
Androgens (male hormones found in all genders) stimulate sebum production. This is also why you will often find someone suffering an acne flare during puberty, menstruation or conditions such as PCOS.
Genetics:
You’re 4x as likely to get acne if your parents had it.
Debunking Acne Myths
Myth: “Acne is a result of poor hygiene.”
Fact: Washing too much can aggravate acne by irritating the skin.
Myth: “Popping pimples makes them heal faster.”
Fact: Causes bacteria to spread and increase scarring.
Myth: “Sun exposure clears acne.”
Fact: UV rays temporarily mask redness, but damage skin long-term.
Treatment
OTC (Over-The-Counter) Options
Benzoyl Peroxide:
Kills bacteria and reduces inflammation (e.g., PanOxyl).
Salicylic Acid:
Sloughs off dead skin cells (e.g. Paula’s Choice 2% BHA)
Retinoids:
Clear pores and increase cell turnover (e.g., Differin Gel).
Prescription Treatments
Topical Antibiotic—Clindamycin or erythromycin for bacterial overgrowth.
Oral Medications:
Antibiotics (doxycycline) for moderate inflammation.
Birth Control Pills Regulate hormones in women
Isotretinoin (Accutane): For severe, persistent acne.
Procedures
Chemical Peels:
Glycolic or salicylic acid peels for exfoliation.
Laser Therapy:
Attacks bacteria and sebum production.
Cortisone Injections:
Reduce cysts in 24–48 hours.
Do Natural Remedies Work?
Some natural treatments appear promising, but the evidence is mixed:
Tea tree oil :
Antimicrobial, but dilute before use.
Some studies show, it decreases inflammation (Zinc Supplements)
Aloe Vera:
Calms redness but doesn’t stop breakouts.
Be careful: Lemon juice, toothpaste and undiluted essential oils can burn skin.
Skincare Regimes for Sensitive Skin
Morning:
Mild cleanser (CeraVe Hydrating Cleanser).
Toner (Thayers Witch Hazel) — no alcohol.
Oil-free cream (Neutrogena Hydro Boost).
Non-comedogenic sunscreen (EltaMD UV Clear)
Night:
Two-step cleansing (oil-based + water-based).
Exfoliate (salicylic acid 2–3x weekly)
Retinoid (use a pea-sized amount)
Moisturize.
Avoid — Harsh scrubs, heavy oils and fragranced products
How Diet Affects Acne: The Easy Way to Prevent Breakouts
Certain foods have been associated with acne in studies:
High Glycemic Index Foods:
Blood sugar spikes cause inflammation (e.g., white bread, soda).
Dairy:
Hormones in milk could cause breakouts.
Omega-6 Fatty Acids:
Common in processed snacks; pro-inflammatory.
Diet for Acne:
Incorporating whole foods, antioxidants (berries, leafy greens), and omega-3s (salmon, walnuts).
Preventing Acne Scars
Don’t Pick! :
Let pimples heal naturally.
Wear Sunscreen:
Ultraviolet — or UV — exposure will darken scars.
Treat Early:
Prescription retinoids; laser therapy for extreme cases.
When to See a Dermatologist
Consult a professional if:
- OTC products are non-therapeutic after 8–12 weeks.
- You have painful cysts or lumps under your skin.
- Acne impairs your self-esteem.
- The Emotional Impact of Acne
Acne can cause anxiety, depression and social withdrawal. In 2023, 62 per cent of acne sufferers said they felt “ashamed” of their skin. Therapists or support groups can help as well.
Conclusion
Acne is a multifactorial disease driven by environment, genetics, and hormones. There’s no overnight solution, but a customised skincare regime, professional treatments, and a bit of patience can clear things up. Remember, you are not your acne — and with the right technique, it doesn’t have to run your life.
