As of 2014, there is no treatment to make acne scars fully disappear, especially overnight. There are a number of methods that can help reduce their appearance over time, including topical treatments, massage, chemical peels, laser treatments and even minor surgery. Choosing the best treatment depends on the severity of the scarring, the type of scars and the patient's preferences.
There are two different types of acne scars: raised and depressed. Of the two, raised scars are generally thought to be worse, as they can continue to grow over time and are often painful or itchy.
There are many home remedies that can lighten or reduce the appearance of acne scars, including using vinegar or lemon juice, tea tree oil, aloe vera, raw tomatoes, raw potatoes or a mixture of honey and aspirin. There are also a number of over-the-counter products that may help reduce acne scars, often creams containing salicylic acid, alpha-hydroxy acid, antihistamines or corticosteroids. Some of these products are designed for sunken scars, while others may reduce the inflammation and swelling from raised scars.
Chemical peels, laser treatments and surgical dermabrasion are all procedures that remove the top layer of skin and help get rid of some scar tissue. In addition, some doctors also offer collagen injections to help fill in depressed scars, although the effects of this treatment only last for a few months.
