As far as pimple scars on the nose are concerned, this oil is the most beneficial in healing of the hypertrophic scars that are generally raised and red, such as those we get after a burn injury or a surgery. Raised acne scars too are however not very uncommon. So if you have the raised acne scars, you can effectively use tea tree oil to get rid of them.

Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected with bacteria. Blockages and inflammation that develop deep inside hair follicles produce cystlike lumps beneath the surface of your skin. Other pores in your skin, which are the openings of the sweat glands, aren't usually involved in acne.

You've probably seen those tiny glass jars filled with liquid and some solid sediment at the bottom—sometimes it's pink, sometimes it's white, and (in the case of my favorite product) sometimes it's flesh-tone. The solid in the jar is usually a mix of drying ingredient like camphor, sulfur, and zinc oxide, but many brands throw in a few little extras. Cult-favorite Mario Badescu Drying Lotion adds calming calamine and exfoliating salacylic acid to their formula, while my favorite, End-Zit Acne Control Drying Lotion, keeps it simple, but comes in several shades so that it conceals your breakout while it treats it.
Treatment of acne scars: For those patients whose acne has gone away but left them with permanent scarring, several options are available. These include surgical procedures to elevate deep, depressed acne scars and laser resurfacing to smooth out shallow acne scars. Newer forms of laser resurfacing ("fractional resurfacing") are less invasive and heal faster than older methods, although results are less complete and the procedures may need to be repeated three or more times. These treatments can help, but they are never completely successful at eliminating acne scars.
Your dermatologist may prescribe Accutane®, if other treatments have not worked. This is a strong medicine that can help prevent scarring and treat active disease. But, Accutane also can cause birth defects. It is important that you are not pregnant and do not plan to get pregnant while taking this medicine. You must use two methods of birth control at the same time. This is done for one month before treatment begins, during treatment, and for a full month after stopping the drug. Talk with your dermatologist about when it's safe to get pregnant. Other side effects of this drug may include dry eyes, itching, mood changes, and changes in the blood and liver. You and your dermatologist can decide whether this medicine is right for you based on the pros and cons. Use any prescribed medicine exactly as you are advised. Taking more medicine than you are supposed to take may make acne or your general health worse. Ask your doctor what to do if you miss a dose.
Avoid touching or rubbing your face, since that can make acne worse. Try to keep your cell phone from touching your face, too. Use earbuds instead of having the phone against your skin. Also, don't lean your face on your hands, which may carry oils and germs that can irritate blemishes. Sweat can also make acne worse. Sweaty after exercise? Wash up.

Exfoliating cleansers and masks: A variety of mild scrubs, exfoliants, and masks can be used. These products may contain salicylic acid in a concentration that makes it a very mild peeling agent. These products remove the outer layer of the skin and thus open pores. Products containing glycolic or alpha hydroxy acids are also gentle skin exfoliants.
