Types of Acne
Understanding your acne type is the first step to finding effective treatment. Each type has different causes, characteristics, and optimal treatments.
Comedonal Acne
Blackheads & Whiteheads
Non-inflammatory acne caused by clogged pores. Blackheads (open comedones) appear as dark dots when the pore stays open and oil oxidizes. Whiteheads (closed comedones) are small, flesh-colored bumps where the pore is sealed shut.
Common causes
Excess oil production, slow skin cell turnover, pore-clogging products, hormonal fluctuations.
Typical location
T-zone (forehead, nose, chin), cheeks.
Recommended treatments
Pro tip
Retinoids are the single most effective treatment for comedonal acne — they prevent the clogs that form comedones.
Inflammatory Acne
Papules & Pustules
Red, swollen bumps (papules) and pus-filled pimples (pustules) caused by bacteria infecting clogged pores. The immune response creates redness and inflammation. This is the most common type of acne people seek treatment for.
Common causes
Bacterial infection (C. acnes) in clogged pores, excess oil, hormones, stress.
Typical location
Cheeks, jawline, forehead, chin — can appear anywhere on the face.
Recommended treatments
Pro tip
The Accure Acne Laser is FDA-cleared specifically for inflammatory acne — it targets the overactive oil glands driving the breakouts.
Cystic Acne
Deep, Painful Cysts
The most severe form of acne. Large, deep, painful, pus-filled cysts form beneath the skin surface. Cystic acne is the type most likely to cause permanent scarring. Individual lesions can last weeks and are extremely painful.
Common causes
Strong hormonal influence, genetics, overactive sebaceous glands. Often runs in families.
Typical location
Jawline, chin, cheeks, back, chest.
Recommended treatments
Pro tip
Don't wait to seek professional treatment for cystic acne. Every day a deep cyst persists, it damages surrounding tissue and increases scarring risk.
Hormonal Acne
Cycle-Linked Breakouts
Acne driven primarily by hormonal fluctuations — especially androgens. Characteristically appears along the jawline and lower face. Often flares around menstrual periods, during stress, or with hormonal conditions like PCOS.
Common causes
Androgen fluctuations, menstrual cycle, PCOS, stress (cortisol), perimenopause.
Typical location
Jawline, chin, lower cheeks — the 'U-zone' where hormone receptors are concentrated.
Recommended treatments
Pro tip
If your breakouts follow a monthly pattern or concentrate on your jawline, hormonal factors are likely involved. Spironolactone is often life-changing.
Fungal Acne
Pityrosporum Folliculitis
Not actually acne at all — it's a yeast (Malassezia) infection of hair follicles that mimics acne. Appears as uniform, small, itchy bumps. The key difference: fungal acne is typically itchy, while bacterial acne usually isn't.
Common causes
Overgrowth of Malassezia yeast, often triggered by humidity, sweat, occlusive products, or antibiotic use.
Typical location
Forehead, chest, back, shoulders — areas prone to sweating.
Recommended treatments
Pro tip
If your 'acne' is itchy, uniform in size, and doesn't respond to traditional acne treatments — it might be fungal. See a dermatologist for proper diagnosis.
Nodular Acne
Hard, Deep Bumps
Hard, painful lumps deep within the skin. Unlike cysts, nodules are solid rather than pus-filled. They don't come to a head and can take weeks or months to resolve. High risk of scarring.
Common causes
Severe inflammation deep within the skin, hormonal factors, genetics.
Typical location
Face, back, chest — can occur anywhere.
Recommended treatments
Pro tip
Never attempt to pop or squeeze a nodule — this pushes infection deeper and almost guarantees scarring. Professional treatment is essential.
Adult Acne
Post-25 Breakouts
Acne that persists past teenage years or appears for the first time in adulthood. Affects up to 50% of women in their 20s and 25% of women in their 40s. Often hormonal in nature and can be psychologically distressing.
Common causes
Hormonal changes, stress, medications, cosmetics, genetic predisposition.
Typical location
Lower face (jawline, chin) in women; back and chest in men.
Recommended treatments
Pro tip
Adult acne is extremely common — you're not alone. The approach may differ from teenage acne, often requiring hormonal management or targeted laser treatment.
Back Acne (Bacne)
Body Acne
Acne on the back, shoulders, and upper body. The back has a high density of sebaceous glands, making it particularly prone to breakouts. Can range from mild comedones to severe cystic lesions.
Common causes
Friction from clothing/backpacks, sweat occlusion, tight workout clothes, same factors as facial acne.
Typical location
Upper back, shoulders, lower back.
Recommended treatments
Pro tip
Shower immediately after sweating, use a benzoyl peroxide 10% body wash (leave on for 2-3 minutes before rinsing), and avoid tight, non-breathable clothing.
