profractional can be done at varying depths and heats. usually it is combined with microlaser peel which is more controlling of "downtime."no heat is used for scar remodeling or dermal melasma. heat can be used in laser skin rejuvenation situations depending on the patients skin type. darker skin types risk post inflammatory hyperpigmentation as the amount of heat used goes up. theheat produces a biological response over time and no tightening is seen initially.
