While the appearance of acne crater scars will gradually lessen over time, they will not completely go away. You may wish to seek treatment from a dermatologist to accelerate the process. The American Osteopathic College of Dermatology recommends waiting to treat acne scars until you have not experienced active acne for several months. Before consulting a dermatologist, try a few home remedies to reduce the scars.
Cleanse the skin with water and mild soap. Dip a cotton swab in lemon juice, then apply it to the scar. Allow the lemon juice to stay on the scarred area for about 10 minutes, then thoroughly rinse. Repeat once daily until the scar lightens. Apply sunscreen before going outside, as lemon juice may make skin more susceptible to sun damage.
Mix 2 tsp water with 1 tsp baking soda. Rub the mixture gently on the crater scars for about a minute. Rinse. This will help exfoliate the skin cells, which allows new skin cells to form.
Apply a drop of olive oil to the crater scar. Rub it in the skin to moisturise. Olive oil may help lessen the appearance of the crater scar by softening the skin's texture. It also provides elasticity.
Make an appointment with a dermatologist. Discuss your expectations for your post-treatment skin appearance. Your dermatologist will recommend a course of treatment for you, which may depend on the extent of the scarring, your skin type as well as which procedures you feel most comfortable undergoing. Not all acne scar procedures are appropriate for crater scars. For example, a punch excision surgery, which involves lifting the scar surgically and suturing the skin together so that it lies flatter, is more appropriate for much deeper scars, known as "ice pick" scars. As crater scars are shallower, you may wish to consider non-surgical options instead.
Undergo a V-Beam laser treatment if your crater scars contain red pigmentation. Removing the redness with this particular type of laser can help diminish the appearance of your acne scars. There is no recovery time following this procedure. You may experience some discomfort. Ask your dermatologist about applying a topical anaesthesia to minimise possible pain.
Undergo a series of chemical peels to develop new skin cells and lessen the appearance of crater scars. This treatment removes skin cells on the top layer of your skin, causing new skin cells to grow and helping to lessen acne scars. The number of chemical peels you'll need depends on the severity of your scars. You will likely experience redness and irritation for about a week after treatment.
Ask your dermatologist about injectable collagen or other dermal fillers if you prefer to avoid experiencing redness for a week. These injections lift up the skin and fill in the crater scar. There is no recovery time needed for this treatment; however, the results are temporary. According to Total Dermatology, the injections may last about three to six months.
