Hello, To prevent acne you should have home made nutritional food that is less spicy & less oily. Take more vegetarian protein & yogurt. Avoid non veg food & take regular showers. To get rid of wrinkles use vitamin E supplements or take vitamin E rich food. Whitening serums are effective to lighten your skin. However, they cannot be used for long time as they may cause thinning of the skin & increase sensitiveness thereafter. You are suggested to visit a dermatologist, get clinically examined. You may need microderm-abrasion, chemical peeling or laser skin lightening therapy. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nupur K, General & Family Physician
