The dryness and darkening are common side effects of Medi Salic cream (salicylic acid and betamethasone). First, please stop using this cream. To help your skin heal, apply a gentle, fragrance-free moisturizing cream containing ceramides or hyaluronic acid multiple times a day to restore your skin barrier. Crucially, apply a broad-spectrum sunscreen daily, as your skin is currently very sensitive to the sun, which can worsen the darkening. If there is no improvement in a few weeks, please consult a dermatologist for personalized guidance.

Yes, clobetasol propionate and salicylic acid ointment can be highly effective for treating lichen planus, especially thick or stubborn patches. Clobetasol is a potent steroid that quickly reduces inflammation, swelling, and itching. Salicylic acid acts by softening and removing scaly skin, which allows the steroid to penetrate deeper and work more effectively. Because clobetasol is very strong, it is important to use this medication exactly as prescribed by your doctor. Avoid applying it to sensitive areas like the face or groin, and use it only for the recommended duration to ensure safe and successful healing.
