Halo HFL is a revolutionary laser because it is a simultaneous combination of ablative and non ablative lasers. The effects can be very dramatic. This is no different for darker skin types. I have several patients skin types 1-6 we have treated (we were the first in the country to do so). In addition, Ive consulted with several doctors from Thailand, Japan, Korea and China regarding safe treatment parameters for Skin types 4,5 and 6. Patients have experienced increased skin reflectivity (the Halo glow), improvement in texture and improvement in pores. Most notably, fine lines and wrinkles around the eyes improve dramatically. Please feel comfortable visiting your local provider who has Halo. If they haven't treated skin type 4 or 5 they will know how to reach out to me.Best of luck - -CR
