To clear scars caused by accidents, roast turmeric powder (khadi haldi not the packed turmeric available in markets) and mix desi ghee into it. Gently apply the mixture on scars with fingertips and wash off after 20 minutes. This mixture completely clears scars but it is always good to ask your physician before starting any beauty regime. Another homemade remedy to clear scars is by using baking soda. This is a natural exfoliator, which aids in gently scraping the scar tissue layer by layer. Make a light paste using two parts of water and one part of baking soda. Gently scrub the scarred area with this mixture for about a minute. Rinse off. Make sure you avoid rubbing vigorously.
