Subcision is one of several methods used for the treatment of depressed scars.
Subcision is used to break up fibrous bands that cause rolling scars. This technique is performed under local anaesthesia by inserting a needle under the skin that is parallel to the skin surface. It is essential that a dermatologic surgeon performs this procedure as the needle must stay in the plane between the dermis and subcutaneous tissue. The needle is gently advanced or retracted in a piston-like motion, cutting the tethering bands. The procedure causes bruising which fades within seven days. This approach, where appropriate, achieves significant improvement, usually within two to three sessions. Rolling acne scars respond particularly well to this technique.
Subcision is used to break up fibrous bands that cause rolling scars (scars that give the skin a wave-like appearance). The technique is performed under local anaesthesia by inserting a small hypodermic needle under the skin that is parallel to the skin surface. The needle is gently advanced or retracted in a piston-like motion, severing the tethering bands.
Most skin types can undergo this procedure, but in darker-skinned individuals there is the possible risk of hyperpigmentation.
The procedure will cause bruising which fades within seven days. This approach, where appropriate, achieves significant improvement in the reduction of acne scars, usually within two to three sessions. Rolling acne scars respond particularly well to this technique.
Usually around two to three treatment sessions are required for subcision to produce significant improvement in an acne scar.
Patients are able to return to their normal activity that day. Bruising is possible, especially if patients have been taking a blood-thinning medication such as Aspirin.
Local anaesthesia to the involved sites is required, as the procedure could not be performed otherwise.
Avoid blood-thinning medications such as Cartia, Aspirin and anti-inflammatory pills. Naturopathic medications should be discontinued one week before the procedure.
Avoid the same products for a further week.
