Acne in Bengaluru: causes, types and an honest treatment guide
Most adult acne in Bengaluru isn’t simple. It’s usually a layered story — hormonal flares from PCOS or perimenopause, sweat-and-pollution clogged pores, a barrier broken by months of TikTok-recommended actives, and old marks from breakouts you treated wrong years ago, all happening at the same time.
There’s no single thing to “fix.” And that’s why a real acne plan takes time, sequence and patience — not 30 random products.
Here’s how we approach acne at SkinWise — what causes it, how the types differ, and what an honest treatment plan looks like for Indian skin.
What acne actually is
Acne is a chronic inflammatory condition of the hair follicle and the sebaceous gland next to it. Four things go wrong simultaneously:
- Excess sebum (oil) production, often driven by hormones
- Abnormal cell turnover inside the follicle, leading to a plug of dead cells and oil
- Bacterial overgrowth — specifically Cutibacterium acnes, which thrives in the plugged follicle
- Inflammation triggered by the bacteria, dead cells and immune response
The visible result depends on which of these processes is dominant and how deep into the skin it travels:
- Blackheads (open comedones) — plugged pores open at the surface; the dark colour is oxidised sebum, not dirt
- Whiteheads (closed comedones) — plugged pores covered by a thin layer of skin
- Papules — small, red, inflamed bumps
- Pustules — papules with a white tip of pus
- Nodules — deep, painful lumps under the skin
- Cysts — deeper, larger, often pus-filled lesions that almost always scar
Treatment differs by lesion type. Spot-treating cystic acne with a face wash won’t help. Treating mild comedonal acne with oral isotretinoin is overkill.
The most common acne types we see
1. Hormonal acne
The classic adult presentation in Indian women: breakouts along the jawline, chin, neck, sometimes around the mouth. Often cyclic, worse in the week before menstruation. Frequently associated with PCOS / PCOD, especially when combined with irregular periods, hirsutism (excess facial hair) and hair fall at the parting.
The hormonal trigger means topical treatment alone often plateaus. We frequently combine topicals with oral therapy (spironolactone, sometimes a short course of contraceptive pills coordinated with your gynecologist).
For the full picture, see our PCOS skin and hair service overview.
2. Comedonal acne
Blackheads and whiteheads, primarily on the T-zone (forehead, nose, chin). Often without inflammation — just a steady stream of clogged pores. Common in teens, oily-skinned adults, and people who use heavy makeup or sunscreens.
Treatment is usually topical: retinoids overnight, salicylic acid washes, salicylic chemical peels in clinic, and (importantly) reviewing the products that may be clogging the skin.
3. Inflammatory acne
Red, swollen papules and pustules. Painful to the touch. Often distributed across the cheeks, jaw and forehead. The most common adult-acne presentation we see.
Treatment combines topicals (retinoids, benzoyl peroxide, azelaic acid) with oral antibiotics in moderate-to-severe cases, and oral isotretinoin for severe or scarring acne.
4. Nodulocystic acne
Deep, painful nodules and cysts. The kind of acne that scars almost certainly without aggressive treatment. Often requires oral isotretinoin, sometimes intralesional steroid injections for individual flares.
This is the type where waiting too long causes permanent damage. If you have nodulocystic acne, the right next step is a consultation, not another over-the-counter product.
5. Adult acne (post-30)
Different from teen acne in a few important ways. Lower oil production, slower healing, more pigmentation residue. Often hormonally driven. Frequently combined with melasma (because the same patients are aged 30–45, frequently female, and have multiple skin concerns interacting).
The plan for adult acne has to be gentler than for teen acne — barrier-friendly, slower escalation, more attention to pigmentation that follows the breakouts.
6. Bacne (back / chest / shoulder acne)
Often missed because it’s not on the face. Important to treat — both for its own sake and because it tells us something about systemic drivers (hormones, sweat retention, certain fabrics, gym hygiene).
Treatment combines body washes with benzoyl peroxide, topical retinoids on the back, sometimes oral therapy, and back peels for stubborn cases. Especially relevant before weddings (saree blouses) and summer.
Acne scars are a separate problem
This is one of the most important distinctions we make at the first consult.
Active acne is the breakout you can see today — the red bumps, the cysts, the new pimples appearing. This is treated medically.
Acne scars are the textural changes (ice-pick, rolling, boxcar pits) and pigmentation (post-inflammatory hyperpigmentation, or PIH) that linger long after the active acne has calmed. These need different treatments — microneedling, microneedling with radiofrequency, fractional lasers, dermal fillers, sometimes punch excision for specific scar types.
Trying to treat scars while active acne is raging is the most common reason scar revision plans stall. We typically calm the active acne for 3–6 months before starting any scar work.
What actually drives Bengaluru acne
Things we see consistently in our patient base in Bengaluru:
- Pollution and traffic exposure — particulate matter clogs pores and increases inflammation
- Helmet acne — especially common in two-wheeler commuters; friction and trapped sweat under the chin strap
- Hard water — many Bengaluru apartments have hard water that can disrupt the skin barrier
- Long air-conditioned hours followed by hot afternoons — climate variability stresses the barrier
- PCOS — possibly the most underdiagnosed driver of adult acne we see
- Over-cleansing — the “my skin is oily so I should wash more” trap, which strips the barrier and triggers rebound oiliness
- Aggressive at-home routines — vitamin C + retinol + AHA + BHA + niacinamide in the same week is the modern equivalent of harsh soap
Our approach to acne at SkinWise
We treat acne in clear, sequenced phases. Trying to do everything at once is the fastest way to leave behind new scars.
Phase 1: barrier repair (weeks 0–4)
Most patients arrive after months of unsuccessful self-treatment. The skin is often over-stripped, sensitive, and reactive. Before we add anything aggressive, we strip the routine down to:
- Gentle, fragrance-free cleanser (twice daily)
- Barrier moisturiser
- Daily SPF 50 sunscreen
- Spot treatment if needed
This phase rarely feels exciting but it’s where most stalled acne plans get unblocked.
Phase 2: targeted prescription (weeks 4–12)
Once the skin can tolerate it, we add:
- Topical retinoids (adapalene, tretinoin) overnight, slowly escalated
- Benzoyl peroxide for inflammatory acne
- Azelaic acid for sensitive skin or combination acne / pigmentation
- Oral antibiotics (doxycycline) for 8–12 weeks in moderate inflammatory acne
- Spironolactone for hormonal acne in adult women
- Oral isotretinoin for severe nodulocystic or scarring acne, after thorough counselling on benefits, side effects and monitoring requirements
Phase 3: in-clinic procedures (weeks 8+)
Once active acne is calming:
- Chemical peels — salicylic for oily / comedonal acne; mandelic or glycolic for post-acne marks
- Comedone extraction when needed
- Intralesional steroids for individual stubborn cysts
Phase 4: acne scar revision (months 6+)
Only after active acne is stable:
- Microneedling for mild texture scars (4–6 sessions)
- Microneedling with radiofrequency for deeper rolling and boxcar scars
- Subcision for tethered rolling scars
- TCA CROSS for ice-pick scars
- Fractional laser for diffuse texture
Phase 5: maintenance
Indefinite. Light topical use, sunscreen, periodic reviews. Acne is a tendency that responds to ongoing care, not a one-time cure.
What NOT to do
The most common mistakes we see:
- Squeezing or popping breakouts — drives the contents deeper, increases inflammation, leaves scars
- Using random “acne kits” sold online — most contain irritating concentrations of active ingredients without medical oversight
- Stacking too many actives — vitamin C + retinol + AHA + BHA + niacinamide in 24 hours is usually a barrier disaster
- Stopping topicals when skin looks clear — acne tendency is chronic; maintenance prevents relapse
- Skipping sunscreen because “sunscreen causes acne” — modern formulations rarely do; finding the right non-comedogenic sunscreen is a 1-week experiment, not a reason to abandon photoprotection
- Self-prescribing isotretinoin — this requires monitoring (blood tests, pregnancy checks if relevant) and supervised dosing; black-market sourcing is dangerous
Frequently asked questions
How long before I see improvement? Most acne plans start showing visible reduction in new breakouts by week 4–6. Pigmentation and marks settle over 3–6 months. Scar revision is a separate, longer journey.
Will my acne come back if I stop treatment? For hormonal acne and adult acne, yes — usually within 6–12 months of stopping. We typically maintain a light topical regimen indefinitely, with periodic reviews.
Is diet relevant? For most people, yes — but not in the way social media frames it. High-glycaemic foods, very high dairy intake (particularly skim milk in some studies) and whey protein supplements can worsen acne. Targeted dietary changes outperform generic “anti-acne diets.”
Can I do facials at a salon during acne treatment? Generally we recommend pausing aggressive salon facials during active acne treatment. Gentle in-clinic facials are different and protocol-driven; salon facials with steam and aggressive extraction can spread infection.
What about laser for acne? Some lasers (Nd:YAG, IPL with specific filters, photodynamic therapy) can complement medical treatment in selected patients. They don’t replace medical therapy — they augment it once the skin is calm.
Why does acne flare around my period? The drop in estrogen relative to progesterone in the late luteal phase increases sebum production and can drive inflammation. Hormonal acne tied to cycle phases responds well to spironolactone or coordinated contraceptive therapy.
Will birth control fix my hormonal acne? Sometimes yes — certain combined oral contraceptives are specifically prescribed for hormonal acne. But the decision to use hormonal contraception involves more than acne; we coordinate with your gynecologist.
My teenager has acne. When should we see a dermatologist? If over-the-counter products haven’t helped in 3 months, if there are painful nodules, if scars are starting to form, or if it’s affecting confidence and social participation — sooner rather than later. Acne treated early scars less, period.
