Laser skin rejuvenation involves the treatment of surface skin irregularities such a fine line, enlarged pores and benign pigmented and vascular lesions by using a light based system such as a laser. At Vascular and Endovascular Institute of MI, P.C. we use Candela GentleMax Pro the state of the art lasers to achieve the best results with minimal discomfort
Through the process of selective photothermolysis of melanosomes. The melanin within the pigmented lesion absorbs the light energy. Heat then destroys the melanin containing keratinocytes and potentially the melanosomes within the melanocytes itself.
After laser (1 minute to 48 hours later), the melanin undergoes a chemical change and turns darker (referred to as micro-crusting). The cells that contain this darker melanin travel towards the stratum corneum (outermost layer of the epidermis) and then slough off. This takes about 5-7 days on the face and 14-21 days in other areas.
When treating pigmented lesions you need a contrast in color between the lesion and the surrounding skin. With lighter skins, there is more contrast between the skin and the lesion so a higher fluence (energy) can usually be used and better results can be achieved. With darker skin types there is less contrast between the skin and the lesion so lower fluences must be used and modest results are generally achieved over a greater number of sessions.
The number of sessions a patient needs to obtain optimal results will depend on:
Due to quicker healing time on the face, laser photo rejuvenation should be performed at 4-week intervals and 6-week intervals on the body. However, if residual micro-crusting is present, the treatment should be delayed until it is totally resolved.
Unfortunately, pigmentation can return if the patient does not practice sun protection and wear an SPF 30+ daily. A melanin inhibiting cosmeceutical will also help to maintain results such as Aspect’s Pigment Punch. Despite that the patient has been doing all things instructed, it is still possible for the skin to re-pigment. In this case, maintenance sessions may be required.
