In her book, "Beauty by Nature," Brigitte Mars writes that the skin has the ability to regenerate and heal. There are three stages of skin healing, with the first being when a scab forms along with any redness or swelling. New skin is then formed underneath a scab in the next stage, with the final being when both the inner and outer layers of skin rebuild. She writes that new scars are easier to heal that older ones, and some scarring tendencies may be genetic. Scars can take two months to several years to heal. Eating foods rich in vitamin C and taking vitamin C supplements may help to speed up this process.
Take the recommended dose written on the label of a vitamin C supplement. Take it daily until the scar has healed.
Cleanse the area of the scab with hydrogen peroxide and a cotton ball. Apply a moisturizer that is rich in vitamin C to skin.
Eat vitamin C-rich fruits and vegetables during the day, such as apricots and apples, suggests Mars. Other vitamin C-rich foods include grapes, raspberries and blackberries, according to Douglass Wall in his book "Doc Herb's Plant Survivalist."
Drink a glass of water and lemon juice daily. Lemon is high in vitamin C and helpful for scars, according to Mars.
Mix a drink of cherry seed powder and water. Drink it a few hours after drinking the water and lemon juice. Wall suggests this remedy high in vitamin C for scar treatment.
Zinc-rich foods, such as peanuts, Brazil nuts, pumpkin seeds and turkey meat, may also help scars. Foods that have vitamin E and B are also helpful, such as millet, sea vegetables and rye.
Do not over clean scars and wear sunscreen when going out into direct sunlight.
Do not pick at scars. Place a butterfly or other type of bandage on to protect the scar if necessary. A dermatologist or doctor may be able to help prescribe medication or administer skin therapies, such as laser resurfacing.
