Applying a baking soda paste or dabbing lemon juice to the affected skin areas are two different natural remedies used to remove acne scars. Making a baking soda paste involves combining approximately 1 tablespoon of baking soda with 2 to 3 tablespoons of water. An application of this paste on the acne scars should be left on overnight and washed off in the morning.
Besides helping to clear acne scars, baking soda is useful for skin exfoliation. However, because some people may have allergic reactions to baking soda, it is wise to do an allergy test on a small area of the skin prior to using this natural remedy.
Applying either a lemon juice facial or dabbing juice just on the acne scars may help to diminish or fade dark acne scars. The treatment should be left on for 20 minutes before being rinsed off with warm water.
