to the 10% mandelic/10% malic acid formula following a few weeks of conditioning with the lower concentration. The pH of both products is 3.1 to 3.3. The personal experience of one author (M.B.T.) has shown mandelic/malic acid to be a less irritating
α-hydroxy acid than glycolic acid and better tolerated in PIH-sensitive darker skin types.
This study supports the safe and effective use of a full-face iontophoresis mask for treatment of melasma as an important method for obtaining sufficient concentrations of vitamin C at therapeutic levels and skin depth to effect a favorable clinical response. The long-term use of a novel mandelic and malic acid skin care regimen further supports sustained improvement
(mean, 26 months) when used in combination with a strict sun-protection protocol. Compliance with a strict regimen
of sun protection and avoidance is difficult to measure. It is assumed that the patients in this study were much less than 100% compliant; however, a satisfactory improvement in melasma and PIH was still achieved.
