as you are 21 year old the acne is mainly due to hormonal changes. as far as scars are concerned do not peel or squeeze your acne. the scars which are already present can be lightened off. for acne try herbal things at home because the cause is very important. as your hormones will get balanced with age the acne will start reducing. take turmeric and sandalwood powder and add rose water to it. make a paste and apply this paste early in the morning. after 10 minutes wash it off gently with water and wipe your face with a soft cotton towel. for scars i suggest you apply aloe vera gel on them twice a day. this will help in lighting them. use mild herbal face wash and do not use harsh soap for face. avoid going directly in sunlight apply sunscreen before going outside. avoid taking the stress avoid excessive spicy and junk food caffeinated drinks etc. drink plenty of liquids and take fresh fruits and vegetables. however if acne is due to some infection then you need to visit a nearby dermatologist otherwise hormonal related acne problem will settle down with time. for further information consult an ayurveda specialist online --> <link>
