The concept of selective photothermolysis (Anderson et al. 1983) emphasizes both the selective damage and minimum light energy requirements seen with current laser technology. However, the use of such a short pulse width laser system may become inapplicable when the target absorption is nonuniform over a treatment area. This may be seen when the actual target exhibits weak or no absorption, yet other surrounding portions of the target exhibit significant absorption. If this is the case, the weakly absorbing part of the target chromophore has
