Hi Thank you for asking HCM I have gone through your query.By natural way you can apply lemon juice on scars by a cotton ball.In case of sensitive skin you can mix it with some rose water.You can also use baking soda diluted in water.Applying honey at night and washing in the morning daily also helpful.You can also use aloe vera, raw potatoes or tomatoes for application on scars.You should also avoid sunlight.Sun exposure will increase darkening of scars.You should not pop the white head as it can form another scar.You can apply nicomide gel in such pimples.Sunscreen application and applying creams with hydroquinone tretinoin and flucinolone on scars will be helpful also.Hope this may help you. Let me know if you have any further query.
