Acne Treatment

Inflammatory acne — Nodular acne — Cystic acne

Inflammatory acne occurs when clogged hair follicles become infected and inflamed by bacteria, ranging from red papules and pustules to nodules (large, deep, and painful bumps) and cysts (large, deep pockets of inflammation under the skin). The deeper the inflammation, the higher the risk of atrophic (pitted) scars. Treatment is tailored to the severity level, utilizing monitored topical and oral medications; comedone extraction should only be performed once the lesions have matured—never pop them yourself.

How Does Inflammatory Acne Form?

Hair follicles clogged with sebum and dead skin cells create an ideal environment for *C. acnes* bacteria to proliferate; the immune system responds, triggering swelling, redness, and pain. If the follicle wall ruptures beneath the skin, inflammation spreads deeper into the dermis—forming nodules or cysts. This destroys collagen and leaves atrophic scars, even if you never pop them.

Distinguishing the Four Common Types

Papules: small red bumps with no visible pus. Pustules: white or yellow heads surrounded by an inflamed red base. Nodules: hard, painful bumps larger than 5 mm with no head that can persist for weeks. Cysts: soft, fluid-filled lesions deep under the skin that may interconnect, leaving broad atrophic scars. A single face often presents a mix of these lesions, so treatment protocols are tailored to target the most severe type present.

Why You Shouldn't Pop Inflammatory Acne Yourself

Inflammatory acne does not have a surfaced core; squeezing only pushes inflammatory fluids deeper and into neighboring follicles. Bacteria from your hands can enter the open lesion, doubling the inflammation and making hyperpigmentation and scarring almost inevitable. A popped blemish may look "flatter" for a few hours, only to swell up significantly more the next day—this is the physiological norm, not bad luck.

Severity-Based Treatment

Mild inflammatory acne: topical anti-inflammatory agents, benzoyl peroxide, and nighttime retinoids. Moderate acne: short-term prescription oral antibiotics combined with topical treatments to prevent antibiotic resistance. Nodulocystic acne: consideration of oral retinoids with regular blood test monitoring, intralesional injections for persistent, painful lesions, and adjunctive light therapy. All oral medications must be prescribed and monitored by a doctor—never self-medicate based on online advice.

What BonBoz Does

Our dermatologists examine your skin, grade the severity based on the lesion count and type, review your medical and medication history, prescribe a tailored protocol, and schedule follow-ups every 4–6 weeks to make necessary adjustments. Painful nodules are managed in-clinic using sterile techniques. Once active inflammation has remained stable for at least several months, the physician will transition your treatment to a regimen focused on atrophic scarring and post-inflammatory hyperpigmentation.

Severity levels

1

Mild — red papules, small pustules

Fewer than 20 lesions, no nodules. Typically controlled with topical prescription medication for 6–8 weeks.

2

Moderate — multiple pustules, a few nodules

20–50 lesions, including 1–5 nodules. Combination of topical and short-term oral medications, medical-grade acne extraction, and post-inflammatory hyperpigmentation monitoring.

3

Severe — widespread nodules and cysts

Multiple painful nodules/cysts with potential scarring. Systemic regimen with routine laboratory monitoring; prioritized on controlling inflammation and minimizing new scarring.

When should you see a doctor?

  • Large, hard, painful acne nodules persisting for over 2 weeks without resolving.
  • Acne leaves atrophic scars or dark spots after each breakout — inflammation has reached the deep dermis.
  • Inflammatory acne spreads to the neck, back, chest, or is accompanied by fever and fatigue.
  • You have been self-medicating with oral antibiotics for more than 2 weeks without a prescription.

In-Clinic Cystic Acne Treatment

Extraction of mature acne lesions and intralesional injections for persistent, painful nodules—performed by physicians using sterile techniques.

Learn about this method →

Adjunctive Light Therapy / Chemical Peels

Reduces inflammation, unclogs follicles, and fades post-inflammatory hyperpigmentation through structured protocols once acute inflammation subsides.

Learn about this method →

Post-Acne Atrophic Scar Treatment

CO2 Laser, Microneedling RF, and subcision—indicated only after inflammatory acne has been well controlled for several months.

Cost guidance

Costs primarily include prescription medications and follow-up visits; nodule extractions, chemical peels, and light therapy are charged per session. Treating acne early is significantly more cost-effective than treating subsequent atrophic scars later on—reference price ranges are available in our cost estimator tool.

The final price follows the doctor’s recommendation after an in-person exam. A confirmed quote has no hidden extras.

Frequently asked questions

Do cystic acne nodules go away on their own?

They can subside after 2–4 weeks, but they often leave behind post-inflammatory hyperpigmentation or atrophic scars because the deep inflammation has destroyed collagen. Early medical intervention at a clinic significantly reduces the risk of scarring.

Is spot-treating cystic acne with creams effective?

It is very limited because the inflammation is situated deep within the skin; topical creams mainly work for superficial papules and pustules. Cystic acne requires professional evaluation by a doctor.

Are oral antibiotics for acne harmful?

When used for a short duration under prescription and combined with topical medications to prevent bacterial resistance, they are safe. Prolonged self-medication is what leads to antibiotic resistance and gastrointestinal disturbances.

Are oral retinoids dangerous?

They are highly effective prescription medications for severe acne that require routine laboratory monitoring and strict contraception in female patients. Your doctor will provide comprehensive counseling before prescribing; they must never be self-administered.

What is a cortisone injection for cystic acne?

It involves injecting a small amount of an anti-inflammatory medication directly into a persistently painful nodule to help it flatten within a few days, thereby reducing the risk of scarring. This must only be performed by a doctor under proper indications.

Should home remedies be applied to inflammatory acne?

No. Turmeric, toothpaste, garlic, and similar remedies cause irritation and can introduce secondary infections into open inflammatory lesions.

How long does it take to get inflammatory acne under control?

Topical medications typically take 6–8 weeks; oral medications show faster results for inflammatory lesions. Severe acne requires a systemic treatment regimen lasting 3–6 months. Your doctor will schedule follow-up milestones to adjust the plan accordingly.

Is inflammatory acne on the back and chest treated the same as on the face?

The underlying mechanism is identical, but the skin on the body is thicker and hair follicles are deeper, which often necessitates oral medications and a longer treatment duration; body wash-formulated topicals are also commonly utilized.

When is the right time to start atrophic scar treatment?

Once inflammatory acne has remained stable for several months. Starting scar revision prematurely on actively inflamed skin is both ineffective and risks creating new scars.

Who performs the treatments at BonBoz?

Board-certified Dermatologists directly examine, prescribe, treat cystic lesions, and conduct all follow-up visits — never delegating these tasks to technicians.
