Although many articles claim that using olive oil or lemon juice can help to cure or reduce the appearance of scaring, there is no scientific evidence to support it. You're probably better off using that olive oil and lemon juice to make a delicious salad dressing.
Home Remedies for Scars
Among the many home remedies for reducing scars, aloe vera is probably one of the most popular. Because aloe vera has moisturizing properties, proponents theorize that it increases the elasticity of scar tissue and helps to reduce inflammation. Studies have actually shown that applying aloe vera gel to scar tissue can reduce the size and appearance of scars [source: Mayo Clinic].
Other popular home remedies include vitamin E and cocoa butter. Both of these substances theoretically work for the same reasons that aloe vera does, although there is no consistent evidence to suggest that either of these methods is truly effective. However, because they are topical and natural, unless you have an allergy to one of them, there is no harm in trying [source: Cleft Palate Foundation].
Another home treatment some people try is tea tree oil. Although there is little evidence to support the claim that tea tree oil reduces or repairs scars, it can actually help to prevent acne scarring. Tea tree oil kills bacteria, which is a common cause of acne flare-ups. You can often find tea tree oil in gels and creams that are used for treating acne [source: WebMD].
These remedies are popular for treating acne scarring at home, because people believe them to be less abrasive than chemical treatments. But not all acne scarring is the same. Read on to find out more about acne scars and how to treat them.
