Pustular psoriasis is a rare but more severe form of psoriasis where painful, raised white or yellow pustules appear on red, inflamed skin. It can be limited to the palms and soles or spread over large areas of the body, and often needs specialist care and systemic treatment.
This is general information. With a scan you'll receive a detailed, personalized analysis — including individual risk assessment, progression tracking and recommended actions.
The exact cause of pustular psoriasis is not fully understood, but it involves an overactive immune response in genetically predisposed people. Flares are often triggered by certain medications, sudden steroid withdrawal, infections, smoking, stress, or strong skin irritation.
You’re at higher risk of pustular psoriasis if you already have psoriasis, smoke, take certain medications, or have sudden changes in steroid treatment. Generalized forms can affect the whole body and may lead to serious complications involving the blood, kidneys, and liver.
Treatment focuses on calming inflammation, removing thick scales, and preventing complications, using a mix of creams and systemic medicines. Depending on severity, doctors may use keratolytic creams, topical steroids, calcineurin inhibitors, retinoids, immunosuppressants, and modern biologic drugs, plus phototherapy in stable cases.
You can’t fully prevent pustular psoriasis, but you can reduce flares by not smoking, limiting alcohol, avoiding known drug triggers and harsh skin irritants, and keeping stress and weight under control. Regular check‑ups and early adjustment of treatment, supported by our AI skin analysis, help keep the disease more stable.
Anyone with suspected pustular psoriasis should see a dermatologist, and generalized or rapidly worsening cases often need urgent hospital care. Ongoing follow‑up is important to monitor the skin, adjust systemic treatment, and screen for complications.
Localized, stable pustular psoriasis should be assessed by a dermatologist within a few weeks, but any sudden flare with widespread pustules, fever, or feeling very unwell needs same‑day urgent or emergency care. Generalized pustular psoriasis can be life‑threatening if not treated quickly.

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.
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.
