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.
"Cortisone injections help treat painful acne flareups and are good for getting rid of it quickly. However, they should not be administered regularly," cautions Dr. Bank. "Cortisone shots contain an antiinflammatory steroid medication called triamcinolone, which helps reduce the swelling of a glaring pimple or cyst, normally within 24 to 48 hours."
Physicians commonly prescribe oral antibiotics to patients with moderate rosacea. Tetracycline (Sumycin), doxycycline (Vibramycin, Oracea, Adoxa, Atridox), and minocycline (Dynacin, Minocin), are oral antibiotics commonly prescribed are presumed to work by reducing inflammation. A newer low-dose doxycycline preparation called Oracea (40 mg once a day) treats rosacea. The dose may be initially high and then be tapered to maintenance levels. Patients should consider common side effects and potential risks before taking oral antibiotics.
For many women, acne can be an upsetting illness. Women may have feelings of depression, poor body image, or low self-esteem. But you don't have to wait to outgrow acne or to let it run its course. Today, almost every case of acne can be resolved. Acne also can, sometimes, be prevented. Talk with your doctor or dermatologist (a doctor who specializes in treating skin problems) about how you can help prevent acne and if treatment would help you.

The exact cause of rosacea is still unknown. The basic process seems to involve dilation of the small blood vessels of the face. Currently, health researchers believe that rosacea patients have a genetically mediated reduction in the ability to dampen facial inflammation that is incited by environmental factors such as sunburn, demodicosis (Demodex folliculorum in the hair follicles), flushing, and certain medications. Rosacea tends to affect the "blush" areas of the face and is more common in people who flush easily. Additionally, a variety of triggers is known to cause rosacea to flare. Emotional factors (stress, fear, anxiety, embarrassment, etc.) may trigger blushing and aggravate rosacea. Changes in the weather, like strong winds, or a change in the humidity can cause a flare-up. Sun exposure and sun-damaged skin is associated with rosacea. Exercise, alcohol consumption, smoking, emotional upsets, and spicy food are other well-known triggers that may aggravate rosacea. Many patients may also notice flares around the holidays, particularly Christmas and New Year's holidays.
You may have been told that what you eat affects your skin and that it can be the cause of pimples and outbreaks, but the debate about diet playing a role in acne frequency still rages on. Many dermatologists will vehemently dismiss the claims that food and acne are linked, as so much of the research surrounding this aspect of skin care has been inconclusive. Studies either yielded weak results, or were flawed with too few subjects or lack of control groups. 
Acne scars take many different forms. You might see tiny pockmarks, a swollen keloid, or a discolored area on the skin. And just like the types of scars vary, there isn't a one-size-fits-all fix. Your dermatologist can use a combination of treatments including lasers, chemical peels, or fillers to minimize the spots. "Once there is scarring you can't get the skin back to the way it was before," says Dr. Karolak. "But we can get it to look significantly better, so that [clients] feel more comfortable in social environments."
To get rid of acne scars fast, apply diluted lemon juice to your scars so they lighten up and aren't as noticeable. You can also make a paste with 1 part baking soda and 2 parts water and use it to exfoliate your face, which can reduce the appearance of acne scars. For more stubborn acne scars, apply an over-the-counter cortisone cream to the scars to help them heal faster.

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.
