Patients will be randomly assigned in a double-blind manner to receive on the lesions 0.0003% calcitriol (Galderma, France), 0.1% tacrolimus (Astellas, Pharma, USA), and petrolatum (Aquaphor ointment)in all of them. All subjects were instructed to apply the treatment twice daily. Sunscreen will not be indicated, and hygienic habits are not being changed. Hypopigmented areas are going to be initially evaluated and supervised at 3, 6 and 9 weeks. Digital photographic registration(frontal, right, and left views) with an SLR Fuji FinepixS1pro camera will be taken and analysed by ImageJ software to quantify the reduction area of the plaques. The methods of assessment involve clinical evaluation by investigators, an independent observer, and by the transepidermal water loss (TEWL) with an evaporimeter (Dermalab, Cortex Technology, Denmark), and pigmentary changes using a colorimeter (Chromameter CR-300, Minolta, Osaka, Japan). Water loss will be recorded on each plaque for 60 seconds, as well as the L* (luminosity) and a* (erythema) axis. All adverse effects will be recorded. Statistical analysis was performed using T student, the level of significance was set at 5%. And clinical evaluation will be analysed by means of chi square tests.
