Acne FAQs.
What is the most common type of acne?
Comedonal acne (blackheads and whiteheads) is the most common type and affects nearly everyone at some point. Inflammatory acne (red papules and pustules) is the second most common. Cystic acne is the rarest but most severe form, affecting roughly 11% of people with acne.
How do I know what type of acne I have?
Look at the appearance and location: blackheads and whiteheads = comedonal; red bumps and pustules = inflammatory; deep painful bumps without heads = cystic; itchy uniform bumps on chest/back = fungal; cyclical chin/jaw breakouts = hormonal. Most people have a mix of types.
What is the most effective acne treatment?
Topical retinoids (tretinoin, adapalene) plus benzoyl peroxide is first-line for most acne. For severe or cystic acne, oral isotretinoin is the most effective treatment available. For hormonal acne, spironolactone or combined oral contraceptives are highly effective in adult women.
How long does it take to clear acne?
Most acne treatments take 4–8 weeks for visible improvement and 12 weeks for full effect. Severe cystic acne treated with isotretinoin typically clears in 4–6 months. Without treatment, individual breakouts heal in 1–6 weeks but new ones constantly form.
Should I see a dermatologist for acne?
See one if your acne is moderate to severe, you have any cystic or nodular acne, OTC treatments have failed after 8–12 weeks, you are scarring, or acne is affecting your mental health. Early dermatologist intervention prevents permanent scarring.
