Acne can be problematic for most, but even more so when it leaves behind scars.
Depending on how deep the scarring is, there are two types of acne scarring to distinguish between
Hypertrophic or keloid type: these appear when the body produces too much collagen and it rises above the skin’s surface
Atrophic scars that develop when there is a loss of tissue.
Almost 80% of acne scars are atrophic.
Some may be superficial; meaning the top layer of the skin is affected, while others may be deeper, more depressed such as icepick types. To improve these scars it is recommended to elevate the skin so that its base becomes level and blends with the surrounding skin.
Micro needling works by causing controlled micro injuries to the epidermis (the top layer of the skin). These Micro injuries target the area where the dermal scarring has occurred, and breaks-up fibrous tissue in order to fill-in the area where there has been a loss of collagen.
Several treatments will help the collagen and elastin production fill in the tissue where indentations have occurred. Enhanced collagen production.is seen after 6 weeks. Even after one treatment, (results vary) improvements can be seen. Four to six treatments are recommended for this procedure to be effective. Each treatment should be spaced approximately one month apart.
It is also important to note that Micro needling should not be performed on active acne, as it can spread bacteria to other parts of the face.
Fillers such as Juvederm and Teosyal as well as other hyaluronic acid fillers are gel-like substances that are injected into scars to level them. These products are particularly effective for rolling scars and some less defined boxcar scars. They are safe and well tolerated, giving great results immediately by leveling depressions associated with scars.
Keep in mind that dermal fillers provide immediate improvement but not permanent results. Touch ups will be required every 6 to 12 months depending on the patient and type of scarring.
It is recommended to have micro needling done before any filler, first to elevate the skin as much as possible prior to injections, as well as not to dissipate any filler that has been placed to raise the indented scars.
