The RevLite™ emits light in rapid, short pulses at high peak energy for maximum efficacy and comfort. The impact feels like no more than the snap of a thin rubber band. As the light shatters the pigment and diffuses the lesion, the spot will turn gray or white for a few minutes as the skin absorbs the energy. Any post-treatment discomfort will feel similar to mild sunburn, and any redness will dissipate within a day or two as the skin returns to its natural colour.
