Melabest Cream contains hydroquinone, tretinoin, and mometasone. It is primarily used to treat certain types of facial pigmentation, such as melasma, and is usually recommended only for short-term use under medical supervision. Hydroquinone and tretinoin may help reduce dark spots and improve uneven skin tone, but the cream is not usually the first choice for treating pus-filled acne. Mometasone is a corticosteroid, and prolonged or improper use on the face can lead to side effects such as skin thinning, redness, increased sensitivity, and sometimes worsening of acne. Therefore, using Melabest Cream without a doctor's advice is not recommended. Since you have pigmentation, active acne, dark spots, and combination skin, it is advisable to consult a dermatologist. The doctor can identify the underlying cause and recommend a treatment plan that safely addresses both acne and pigmentation while reducing the risk of side effects.
