Melasma is a chronic, acquired disorder of focal hypermelanosis that carries significant psychosocial impact and challenging for both the patient treating practitioner to manage in medium long term. Multiple treatments have been explored, often combination given many aetiological factors involved its pathogenesis. Therapeutic discoveries treat melasma are topic literature include range modalities, with recent developments including updates on visible light photoprotection, non-hydroquinone depigmenting agents, oral tranexamic acid, chemical peels, laser energy-based device therapy melasma. It increasingly important yet remain up-to-date arsenal available find an efficacious well-tolerated option our patients.

Effectiveness, safety, and patient satisfaction of carboxytherapy as an adjunctive treatment for periorbital hyperpigmentation

Skin Research and Technology, Год журнала: 2024, Номер 30(3)

Abstract Introduction Dark under‐eye circles or periorbital hyperpigmentation constitute a prevalent and challenging cosmetic problem with diverse etiologies types. While modifying exacerbating habits can provide partial relief for the pigmentary vascular factors associated this condition, despite abundance of available treatment options, there is currently lack gold‐standard evidence‐based treatments proposed curing disorder. Objectives This study aimed to assess safety effectiveness carboxytherapy in treating hyperpigmentation. Material Methods In 4‐week single‐arm clinical trial, 20 eligible Iranian patients symmetric received weekly intradermal carboxytherapy. The involved administering 10–20 mL CO2 at rate mL/min temperature 15°C duration ranging from few seconds 1 min. Follow‐up assessments were conducted month after final session. primary outcome was defined as changes ΔE variations pigmentation observed between orbital extra‐orbital skin before trial. Results reported satisfaction statistically significant reduction achieved through lateral ( p = 0.002), middle 0.001), medial 0.001) regions area. total response estimated 20%.

Abstract Background Noninvasive skin rejuvenation treatment is growing in recognition to aesthetic medicine. Aim The objective of the study was assess efficacy and safety 675‐nm laser source photodamaged hands. Materials methods included 21 patients (6 males 15 females) with a mean age 63 (± 9) years. Patients were treated —two three sessions 1‐month interval between sessions. Photos each patient collected at baseline, 3 months after last session. 5‐point Global Aesthetic Improvement Scale (GAIS) recorded their final assessment session (3 months). Results total GAIS scores showed satisfactory results: (71%) experienced 4 score (excellent improvement) changes 6 (29%) (good changes. Clinical images good visible results for management skin. No serious adverse effects recorded. Conclusion This demonstrates improvement pigmentation texture

A 675 nm Laser in the Treatment of Facial Melasma in Dark Skin Types

Photobiomodulation Photomedicine and Laser Surgery, Год журнала: 2025, Номер 43(3), С. 90 - 95

Опубликована: Фев. 3, 2025

Background: Melasma therapy can be difficult and requires employing different treatment approaches. Laser is a good alternative for treating melasma, especially patients with refractory cases. Objective: To evaluate the efficacy safety of newcomer wavelength 675 nm diode laser in melasma darker skin types. Methods: Nineteen female facial were recruited. They received four sessions at one-month intervals using following parameters: power 5-6 W, pulse duration 100-150 ms, spacing 2000 mm, stack one up to 4 passes. One month after last session, evaluation was done subjectively through modified area severity index (mMASI) score objectively Antera 3D camera. Results: After treatment, there highly statistically significant reduction mMASI scores. In addition, scores on camera recorded differences treated areas' melanin hemoglobin average levels. Conclusion: The novel represents safe efficient approach phototype patients.

Comparison of the Efficacy of 1064‐ and 730‐nm Picosecond Lasers for Acquired Dermal Melanocytosis

Journal of Cosmetic Dermatology, Год журнала: 2025, Номер 24(3)

Опубликована: Март 1, 2025

ABSTRACT Background Acquired dermal melanocytosis (ADM) is a pigmentary lesion caused by melanocytes in the dermis. These conditions are refractory, and consensus on treatment remains elusive. Aims To compare efficacy of 730‐ 1064‐nm picosecond lasers ADM to supplement comparison with literature review. Patients: We retrospectively examined patients who underwent laser therapy between April 2021 February 2024. Treatments were performed three times spot irradiation using 730‐nm (3‐mm spot, 1.7–1.8 J/cm 2 ; or 2‐mm 2.5–3.25 ) 3.1–4.0 ). Two months after each procedure, patient satisfaction was evaluated questionnaires, macroscopic findings assessed photographs, melanin accumulation analyzed skin analysis software. Evaluations conducted 4‐point scale (excellent, good, fair, poor), good higher considered effective. Results Seventy‐eight 83 assigned groups, respectively. After sessions, group exhibited superior outcomes terms subjective symptoms (patient satisfaction), objective findings, software improvements. The incidence hyperpigmentation 15.4% 14.5% group, no significant differences observed rates other complications. Conclusions use laser, which possesses high selectivity, relatively deep penetration, short pulse width, suggests potentially more effective for ADM, compared effects conventional wavelength, without increasing

ABSTRACT Background Facial hyperpigmentation due to sun damage, post‐inflammatory hyperpigmentation, and other factors is a common complaint of patients. While lasers topical treatments are frequently used manage standardized way measuring response treatment difficult. Aims The Kesty Hyperpigmentation Scale (KHS) novel clinical instrument created provide consistent approach for evaluating facial in both cosmetic dermatology broader medical settings. Methods This study introduces the KHS, describes process its creation validation, examines practical uses Statistical analysis included Gwet's AC2, Kendall's W , Spearman's ρ /rho, weighted Cohen's kappa, Bland–Altman analysis. Results findings statistical high ordinal agreement, strong rank concordance, minimal bias. supports conclusion that rating reliable valid assessing skin on given 0–3 scale. KHS offers an objective framework measure severity helping clinicians track patient progress after treatments, fostering improved communication with Participants this found scale be user‐friendly, majority expressed interest incorporating it into their practices document conditions.

Dear Editor, Melasma, predominantly affecting darker skin types, especially those within Fitzpatrick phototypes IV-V.1 The treatment approach is further complicated by high recurrence rates and the significant impact melasma can have on patients' quality of life.2 Laser treatments are a component in management melasma, they generally considered as second-line following first-line use topical therapies. Many studies suggests that low-fluence Q-switched Nd:YAG picosecond laser highlighted potentially effective option this condition when combined with other treatments.3 However, there higher risk post-inflammatory hyperpigmentation (PIH) light treatments. Therefore, these should be used caution therapy after treatments.3, 4 A new non-ablative wavelength 675 nm has been found to significantly improve patients which histologically preclinical shown presence selective damage melanin-rich areas.5, 6 aim article present outcomes types IV-V melasma. By exploring efficacy through clinical cases, we seek contribute limited pool for color provide insights into potential specific managing minimal adverse effects.
