The length and quantity of Harmony XL PRO laser hyperpigmentation sessions at Aesthetics of Central Texas will differ among patients and will depend on the extent of the case. However, each visit lasts about 30 minutes, and many people significantly treat their hyperpigmented skin concerns over 3 – 4 sessions scheduled about four weeks apart. At your skin consultation with Dr. Irwin, our staff members will be able to offer specific details involving your cosmetic treatment plan.
