In recent years, the laser treatment of chloasma has gradually matured. Previously, the literature on the treatment of chloasma using large-spot low-energy Q-switched Nd:YAG laser has been reported, but the lack of the latest PTP mode 1 combined with nano-micro-needle introduction of tranexamic acid, etc. The literature on drug treatment of melasma has no specific literature on the clinical efficacy and safety of PTP mode combined with nano-microneedle drugs in the treatment of chloasma.

To this end, we conducted the following experiments to conduct a clinical study of PTP-mode Nd:YAG laser combined with nano-microneedle drug introduction for the treatment of chloasma:

Objective: To investigate the clinical efficacy and safety of PTP mode 1064nm Nd:YAG laser combined with nano-microneedle drug delivery in the treatment of chloasma.

Study method: 32 patients with chloasma. Immediately after treatment with Pd-mode Nd:YAG laser, nano-micro needles were used to repair skin barriers and anti-oxidant drugs, once every 2 weeks, and 6 times a course. MASI score, Lab brightness analysis, doctor’s efficacy evaluation, patient self-evaluation, and adverse reactions were performed before treatment and 2 weeks after treatment.

RESULTS: The MASI score improved by 24% before and after treatment with PTP laser and nano-microneedle in the lesion area of ​​chloasma, and there was a significant difference (P<0.05). The index of response brightness increased by 2.81 (P<0.05). . Efficacy doctors evaluated the effective rate was 69% (22 cases), and no adverse reactions such as hyperpigmentation or hypopigmentation were observed during the whole process.

Conclusion: Using a new PTP mode Q-switch 1064nm laser combined with nano-micro-needle introduction of drug tranexamic acid to treat facial melasma at intervals of 6 times, it is about 70% effective in clinical, it is a safe and effective treatment for chloasma. method.

YAG laser treatment

The 1PTP mode, the dual-pulse mode, converts a conventional single-pulse laser into a two-pulse laser, which converts a traditional higher energy into two continuously stable lower energies.

PTP mode can reduce the peak energy value brought by single pulse laser under the same energy, bring less damage to normal tissue and reduce side effects such as epidermal damage and oozing, which greatly enhances safety and stability. .

Q-switched laser, with mature technology in the field of Q-switched Nd:YAG laser. The unique dual-pulse (PTP) mode global innovation technology converts a traditional single-pulse laser into a two-pulse laser that emits two nanosecond pulsed lasers in 100 microseconds.

PTP

Under the same energy, the peak energy value brought by the single pulse laser is reduced, which causes less damage to normal tissues and reduces the occurrence of side effects such as epidermal damage and oozing. The pain is obviously improved, and the low peak energy is used to treat yellow. Brown spots are more effective and reduce the occurrence of post-inflammatory hyperpigmentation. Continuous heat accumulation can promote collagen regeneration, whitening and rejuvenating skin and tightening pores.
