For active flare-ups, dermatologists usually recommend twice-daily application. Once the plaques have thinned out, you can transition to a maintenance routine of once a day or every other day to prevent the scales from returning.

Medicated shampoos containing Coal Tar or Salicylic Acid are typically used two to three times a week during a flare-up. For daily washing, it is better to alternate with a very gentle, pH-balanced moisturizing shampoo to avoid over-drying the scalp.

Itching often intensifies at night due to changes in body temperature and lower humidity levels. Applying a thick, occlusive ointment or cream before bed can help lock in moisture and reduce the urge to scratch during the night.

While both involve red, itchy skin, psoriasis plaques are typically well-defined with silvery scales and appear on the elbows, knees, or scalp. Eczema (dermatitis) is usually more "bubbly" or "weeping" and often appears in the creases of the elbows and knees.

Moderate sun exposure can help improve psoriasis for many people because UV light slows the rapid growth of skin cells. However, it is vital to avoid sunburn, which can actually trigger a flare-up. Always use a pore-safe sunscreen on non-affected areas.

No. Picking or scratching at psoriasis scales can cause bleeding (Auspitz sign) and may lead to an infection or cause the patch to grow larger. Instead, use a keratolytic cream to gently dissolve the scales so they wash away naturally.

The skin on the face is much thinner than on the body. You should only use products specifically labeled for facial use or those recommended by a professional. Body-strength coal tar or salicylic acid may be too irritating for the delicate facial area.

While diet doesn't cause psoriasis, some people find that anti-inflammatory diets (rich in Omega-3s and antioxidants) help reduce the frequency of flare-ups. Maintaining a healthy weight also improves the efficacy of many psoriasis treatments.

With consistent use of clinical-grade topicals, you may see a reduction in itching and redness within a week. However, it typically takes four to six weeks for thick plaques to fully flatten and for the skin texture to normalize.
