There are several home remedies for the acne scars (pimple holes!). Follow them regularly, twice a day if possible and holes will vanish quickly.
• The garlic cloves. Make paste and apply it on the scars.
• The paste of turmeric and custard.
• Simply apply honey. Add a few lemon drops for better results.
• Make paste of baking soda with water and use it.
• Take the help of fruits. Whichever fruit is there, apply a bit of it on your face.
• Use aloe vera (with sugar).
• You can use coconut oil as a natural moisturizer.
• Use some good acne removal face wash and separate towels and handkerchiefs.
• What I myself use (I don't have holes though) is to make the paste of Sandalwood powder, milk, turmeric, rose water and a bit of tomato juice, apply it on face for half an hour and use some ice cubes after washing the face with water.
• Drink plenty of water and don't touch or rub your face unnecessarily.
