Deeper Laser Treatments for Acne Scars?

I have worked with the Profractional laser for quite some time, and have kept up with innovative uses across the country. In my office, my skin care nurses provide superficial depth treatments to 300 microns, and I perform those that go deeper.
Acne scarring is difficult, because it involves deep dermal elements. Multiple users, including myself, have been increasing the depth of Profxnl treatments to remodel the scarring. Empiric evidence have suggested at least 500 microns, and even up to 700 microns in thicker skin regions like the cheek or chin, in order to be effective. Temple skin is treated a bit less aggressively. I still counsel patients that two to three treatments must be expected. With those treatment parameters, the results have been impressive, even after prior skin resurfacing like C02 or conventional erbium. We also pretreat the skin with a 20 micron microlaser peel just before the profxnl treatment in order to improve the standardization of depth, and minimize the profxnl pattern while healing. Density setting is always 11 %, and coag is usually 1.
I don't feel it's appropriate for an aethetician to use the laser in this range. Find a physician in one of the core disciplines of derm, facial plastics, plastics, or oculoplastic surgery to perform this treatment.
Bleaching cream is recommended, and in my practice with your skin type would be deemed imperative.
Good luck.

Fractional laser is an amazing and highly effective treatment in our office. We use the laser treatment to help with acne scars, large pores, fine wrinkles, tissue collagen loss, scars, sebaceous hyperplasia, active acne, and for brightening dark pigmentation. Although there are very strong fractional lasers such as CO2 laser, we use lighter treatments for corrective skincare and maintenance of results. Our Thulium fractional laser, clear and brilliant laser, and Ultra Thulium laser are excellent options in our clinic. We also perform CO2 fractional and erbium depending on skin tone and tolerance for downtime. Patients do have to use a Melarase cream before and after treatment to help further reduce pigmentation after laser. Melarase AM, Melarase PM, and Melapads can seriously improve surface sun damage and UV related pigmentation. Dark spots can improve with these treatments. I recommend fractional laser for incisional scars as well, especially after plastic surgery.

Anytime a patient will undergo a deep laser profractional treatment, or even a microlaser peel we always like to pretreat the patients skin.  Anytime we have a darker skintype it is mandatory to pretreat with a bleaching agent 4-6 weeks prior to their laser procedure. This not only helps prevent any burning to the barrier layer of the skin, but it also helps diminish any pigmentation issues if that's what the  patient was trying to treat. It may even help the healing processes post laser. For you being a skintype four, the esthetician is being very cautious with her settings but she can probably increase it to 300, and may do spot treatments for the deeper scars.
