“…Many articles have been published regarding lip melanin depigmentation with a laser using near-infrared (1064, 940, and 810 nm) and also the Q-switched 532 nm. Most of the previous studies mentioned adverse effects such as reactivation of herpes labialis, dark crust, scars, swelling, dark pigmentation, burning sensation, patient discomfort, and pain [11,12,[15][16][17].…”

“…Published papers and case reports on laser treatment for lip melanin pigmentation are very few, and some are not reliable due to the very low number of samples or case reports, some cases are done with near-infrared laser with the lips swelling and a painful experience for the patient, and some cases were observed in our clinic with scars or with a prolonged healing period, which could extend 4-6 weeks [11,12,[15][16][17].…”

Background. In the current research, Er,Cr:YSGG laser been used in ablative mode to peel the pigmentation, and many sessions were done to completely remove the melanin pigmentations. Materials and Methods. 85 patients were selected and Er,Cr : YSGG laser with 2780 nm wavelength in ablative mode (iPlus, Biolase, USA) was used to treat patients with dark lip melanin pigmentation, using gold handpiece and MZ 10 tip (diameter of 1 mm), and the parameters were set as follows: energy density 28.7 J/cm2, frequency 30 Hz, water cooling 100%, and air cooling 60%. Results. The vast majority of the patients (82.4%) had mild adverse effects after the lip depigmentation and 74.1% of patients reported complete improvement of the lip with a high satisfaction rate (84.7%) during the follow-up period with a low level of relapse. Conclusion. Er,Cr:YSGG 2670 nm is an effective tool to achieve excellent esthetic results in the treatment of lip melanin pigmentation; it is very well tolerated by patients with minimal adverse effects.

“…Additionally, only few studies examined the safety and efficacy of laser treatment in skin of color [13,14]. e efficacy and safety data of nonablative fractional laser in Saudi patients is limited [15,16] with no data that focus on new technologies such as 1550 nm/1927 nm dual wavelength laser.…”

Background. Treatment of postinflammatory hyperpigmentation (PIH) in patients with dark skin is challenging as the treatment itself might provoke paradoxical PIH. Only few studies examined the safety and efficacy of nonablative laser treatment in these patients. The objective was to examine efficacy and safety of nonablative 1927 nm wavelength laser followed by bleaching creams in the treatment of PIH. Methods. It was a prospective interventional pilot study that was conducted during 2019. All patients were of Fitzpatrick skin type IV who had unsatisfactory response to topical bleaching creams used for at least three months. Patients received one to four sessions of laser treatment (6 weeks apart) followed by topical hydroquinone 4% cream twice daily for 6 weeks. Improvement was assessed by two blinded independent dermatologist evaluators. Results. A total of nine patients were enrolled and the outcome could not be assessed in one patient who was lost for follow-up. The affected sites were the abdomen, face, and other body parts. Three of the eight evaluated patients had excellent response (37.5%), four had satisfactory response (50.0%), and one had nonsatisfactory response (12.5%). The downtime was manifested as edema and erythema that disappeared after 5 to 7 days. Improvement was more evident in first session and it declined in subsequent sessions. None of the patients had paradoxical pigmentation after treatment. Conclusions. Low energy low density nonablative fractional 1927 nm wavelength laser treatment followed by topical hydroquinone 4% cream for 6 weeks is a safe and effective modality for improving PIH in patients with darker skin types.

“…L ip hyperpigmentation can be physiologic or pathologic, and it may be caused by a variety of local or systemic factors including genetics, smoking, or even prolonged administration of drugs (antimalarials or tricyclic antidepressants). 1 Physiologic lip hyperpigmentation is a common cosmetic problem in Asians, as well as in African-Americans and Hispanics. 2,3 It usually occurs during the first 2 decades of life and presents as a patchy pigmentation with a symmetrical pattern on the lip.…”

BACKGROUND Physiologic lip hyperpigmentation is a common aesthetic concern, especially in Southeast Asia. There is limited data on the application of the picosecond laser for this condition. OBJECTIVE To evaluate the efficacy and safety of using a 755-nm picosecond laser in the treatment of physiologic lip hyperpigmentation. METHODS Twenty healthy patients with physiologic lip hyperpigmentation received 5 bi-weekly treatments with a 755nm picosecond laser using a 6-mm spot size, fluence of 0.71 J/cm 2 at 5 Hz. Subjective and objective evaluation on the improvement of lip hyperpigmentation were obtained at baseline, 2 weeks after each treatment and at 1, 3, and 6 months after the final treatment. Patient self-assessment, pain score, and adverse reactions were also recorded. RESULTS All patients completed the study and attended all follow-ups. Most (52.6%) patients presented with moderate clinical improvement at 6-month follow-up. The average melanin index decreased significantly after the fourth treatment (p 5 .048) and at 1-month follow-up (p 5 .026). More than half the patients (70%) reported moderate-to-marked improvement at 6-month follow-up. Only 1 patient presented with a transient adverse reaction of lip edema. CONCLUSION The 755-nm picosecond laser is safe and effective for the treatment of physiologic lip hyperpigmentation in Thai patients.
