Psoriasis is known as psoriasis. Psoriasis on the forehead can usually be relieved by topical medications, systemic medications, and physical therapy. 1. Topical drugs: patients can use moisturizers to strengthen the protection of the skin barrier (such as moisturizing lotion, petroleum jelly, etc.), and glucocorticoid ointment can also be used for topical treatment (mometasone furoate ointment, etc.), which plays an anti-inflammatory role. Patients can also use topical keratin contributing agents (such as salicylic acid ointment, etc.), such drugs can promote the epithelial cells as soon as possible. 2. Systemic drugs: the larger area can be taken orally related to drug therapy. Commonly used drugs are retinoids (such as Avicenna), immunosuppressants (such as methotrexate, cyclosporine, etc.), injectable biologics (such as etanercept) and so on. Combined with bacterial infection, oral antibiotics (such as cephalosporin) can be taken. 3. Physical therapy: Patients with moderate to severe psoriasis can use photochemotherapy to slow down the growth of skin cells and inhibit the activation of immune cells (e.g. long-wave ultraviolet light therapy). Patients can also use bath therapy, that is, hot compresses with a towel on localized scalp areas to soften the scales, thus removing the scales. The above situation, it is recommended that patients seek medical treatment in a timely manner, under the guidance of a professional doctor, combined with their own condition, choose the appropriate treatment method, and follow the doctor’s instructions to receive treatment. The above medications should be used in accordance with medical advice.
