A number of medical and non medical treatments are available to treat acne scars. Although a total correction of scarred tissue deformities cannot always be achieved, the primary goal is to improve the appearance. The more invasive treatments are injections, dermabrasion and lasers, which can be painful, expensive and requires recovery time.

Non invasive Treatments:

Glycolic Acid
Medical studies demonstrate that higher strengths of Glycolic Acid (peels), along with consistence use of glycolic acid skincare products can make a dramatic improvement in the appearance of skin scarred from acne. Research shows that the depth of shallow depressed scars can be reduced significally with repeated Glycolic Acid use. Areas that are hyperpigmented as a result of acne, as well as enlarged follicle, also greatly benefit from Glycolici Acid. Unlike procedures that resolve only the scar itself, Glycolic Acid provides overall skin resurfacing and retexturization, encouraging a more reflective, even toned surface. Additionally Glycolic Acid can address scarring while at the same time it can act as a potent toll for resolving the acne process and preventing new lesions. A combination of Glycolic Acid, Salicylic Acid and Azelaic Acid can provide a even greater resurfacing benefits.(Jan Marini Bioglycolic Bioclear Lotion) If you cannot tolerate Glycolic Acid a great product to use is Skinceuticals Retexturing Activator.

Retinol has been shown to be effective in treating acne scars. lt is thought to stimulate collagen production, division and the growth of cells. It helps with skin care by repairing the skin's lower layers, making the skin appear softer and feel noticeably smoother. Additionally, when Retinol is used with Glycolic Acid, there is a synergistic enhancement and the overall results are are greatly intensified.

Vitamin C

After a month of use you should notice brightening and radiance, but we are talking 3 to 6 months before you see the firming and plumping effects of increased collagen production.

Microdermabrasion removes dead skin cells,which stimulates the growth of new elastic fibres and collagen, improving the overall finish of your skin and evening out skin tone. The scars depth is reduced and a glow is more visible.Regular treatments are needed for optimum results.
Microdermabrasion is often used as part of an overall skin care program because it enhances the effectiveness of other skin care products. This is because by exfoliating the top layer of skin, it allows the active ingredients in other skin care products to penetrate the middle dermal layer of skin where it can be more beneficial.

A new roller device with rows of tiny microneedles is now available for the treatment of acne scars. When the needles penetrate the skin surface, micro-channels form. This allows product penetration past the skin barrier. The physical minute breaks in the skin surface stimulates the skin to produce collagen naturally (Collagen Induction Therapy). New skin forms under the dead scar tissue, hence the skin naturally becomes smoother once it regenerates.To obtain and sustain the treatment results from acne scarring it is recommended to have a course of deeper treatments done at a clinic with a trained professional as well a using a home kit. This simple mechanical device produces results equivalent to laser therapy, without the prolonged recovery or expense. It is rapidly gaining popularity worldwide as a useful part of the Aesthetic Physician's tool kit in the treatment of acne scars and general rejuvenation. 

With all theses treatments you have to persevere with it, you cannot just use the product to improve the skin and then stop, you must persist with the tratment for the best results.
