Novel long pulse potassium-titanyl-phosphate with substructured pulses – An effective tool in treating post-inflammatory erythema: A report of two cases in darker skin

The utilization of lasers is advancing as the range of applications for laser therapy expands, and new devices have been introduced. Vascular coagulation, pigment ablation, skin regeneration, tissue cutting or ablation, and hair removal are the five primary applications of laser therapy for the treatment of dermatological conditions. We present two cases of female patients with bilateral facial redness, one due to electromedical plasmage and the other from fractional carbon dioxide (CO2) laser, in which the target of their therapy was to improve acne scarring. Facial redness in both cases was successfully treated using a potassium-titanyl-phosphate (KTP) laser with cryogen cooling. The KTP laser has demonstrated efficacy in treating erythema associated with various conditions, including CO2 fractional laser and plasmage therapy. One of the advantages of the KTP laser is that it minimizes post-operative purpura and erythema, making it a favorable option for treating erythema itself.
