What is psoriasis?
Psoriasis is a chronic immune-mediated condition where skin cells turn over too quickly, creating thickened plaques with silvery scale. It can be triggered by stress, infection, certain medications and skin trauma.
Types

- Guttate psoriasis — small drop-like spots after streptococcal infection.
- Inverse psoriasis — in skin folds.
- Pustular and erythrodermic — severe forms requiring urgent care.
Treatment
- Emollients daily.
- Topical vitamin D analogue + potent steroid (Dovobet, Enstilar) — first-line for plaques.
- Coal tar and salicylic acid for scale.
- Calcipotriol scalp solution for scalp.
- Phototherapy under dermatology.
- Systemic drugs and biologics for severe psoriasis.
When an online doctor can help
Online GPs can prescribe potent topical combinations, advise on lifestyle factors (smoking, alcohol, weight), and refer to dermatology for moderate-to-severe disease.
