What should you know about Roche-Posay and psoriasis?

Psoriasis can produce defined areas of redness with silvery or dry scale. It may itch, crack, peel, or feel sore, especially when the barrier is disturbed. [Psoriasis](/conditions/psoriasis/) is an immune-mediated condition, so a moisturiser can reduce tightness while leaving the underlying inflammation untreated. Fragrance, harsh cleansing, and vigorous scrubbing may aggravate sensitive plaques. The scalp, face, folds, nails, and genital skin need different advice from thicker skin on the elbows or knees.

Choose a bland, fragrance-free cleanser and apply a rich moisturiser soon after bathing, while skin is still slightly damp. Ingredients such as glycerin, ceramides, or petrolatum can help reduce water loss; stop a product that stings or worsens redness. Do not pick scale or use abrasive exfoliation on plaques. Seek a tailored plan if you have [Dry Skin](/symptoms/dry-skin/), [Itchy Skin](/symptoms/itchy-skin/), or recurrent fissures. Prescribed anti-inflammatory or scale-lifting treatment should be used exactly as directed.

Book a review when plaques are spreading, painful, interfering with sleep, cracking or bleeding, or affecting the eyes, joints, nails, or genital area. Urgent assessment is needed for rapidly widespread redness, fever, feeling very unwell, or extensive skin shedding. These features can signal a serious flare rather than a simple need for richer moisturiser.

Ask which cleanser and moisturiser suit your affected sites, whether your rash is definitely psoriasis, how to combine emollients with prescription treatment, and what to do if [Skin Redness](/symptoms/skin-redness/) or [Scaly Skin](/symptoms/skin-scaling/) suddenly worsens.
