Acne vulgaris is a very common chronic inflammatory skin condition that affects hair follicles and oil (sebaceous) glands, mainly on the face, chest, back, and shoulders. It shows up as blackheads, whiteheads, red bumps, pus-filled spots, and sometimes deeper nodules, cysts, scars, and dark marks.
This is general information. With a scan you'll receive a detailed, personalized analysis — including individual risk assessment, progression tracking and recommended actions.
Acne vulgaris develops when oil glands produce too much sebum, the pores get clogged with dead skin cells, and bacteria in the follicle trigger inflammation. Hormones, genetics, skincare products, diet, stress, and some medications all influence how severe acne becomes.
Acne vulgaris itself is usually not dangerous, but it can leave permanent scars and dark spots and can strongly affect confidence and mental health. In severe, untreated cases, deep infections, painful nodules, and cysts can develop, and very rarely infection can spread more widely.
Acne vulgaris is treated with a mix of topical products (like retinoids, benzoyl peroxide, and antibiotics), sometimes combined with oral antibiotics, hormonal therapy, or isotretinoin in more severe cases. Gentle skincare, avoiding picking, and addressing triggers such as comedogenic cosmetics, stress, or diet are also key, and progress should be checked regularly, for example with our AI skin analysis.
You can’t fully prevent acne vulgaris if you’re genetically or hormonally prone, but you can reduce flares by using gentle, non‑comedogenic skincare, avoiding harsh scrubbing and picking, protecting your skin from UV, and keeping a generally healthy lifestyle. Regular self‑checks and early adjustments, supported by our AI skin analysis, help catch worsening acne before it scars.
See a dermatologist if your acne is moderate to severe, leaves marks or scars, is painful, or doesn’t improve after 2–3 months of proper over‑the‑counter care. Sudden severe acne in adulthood, deep nodules, or strong emotional distress are also reasons to get professional help and to monitor your skin regularly with our AI skin analysis.
Acne vulgaris is usually not an emergency, but you shouldn’t ignore persistent, painful, or scarring acne. Arrange a routine dermatology visit within a few weeks, and seek earlier care if you have deep nodules, sudden severe flares, or signs of infection.

Eczema is a group of inflammatory skin conditions that cause redness, intense itching, dryness, and sometimes oozing or crusting. It can be acute with blisters and swelling or chronic with thickened, cracked skin, and it often flares in cold, dry seasons and improves in summer.
Rosacea is a chronic inflammatory skin condition that mainly affects the central face and causes persistent redness, visible blood vessels, and sometimes acne‑like bumps or eye irritation. It tends to flare in response to triggers like heat, alcohol, spicy food, or stress and usually needs long‑term, tailored care rather than a quick one‑time treatment.
Cystic acne is a severe, chronic form of acne where deep, painful nodules and cysts form in the skin and often leave scars. It usually affects the face, chest, back, and shoulders, and needs proper medical treatment rather than just cosmetic care.
Pustular acne is a common chronic form of acne where inflamed red bumps and white or yellow pus-filled spots appear around hair follicles and sebaceous glands. It usually affects the face, chest, shoulders and back, and can leave dark marks or scars if it is severe or picked.
