Rhodamine intense pulsed light versus conventional intense pulsed light for facial telangiectasias

Evaluation of the Pinhole Method Using Carbon Dioxide Laser on Facial Telangiectasia

Facial telangiectasias are small, dilated blood vessels frequently located on the face. They are cosmetically disfiguring and require an effective solution. We aimed to investigate the effect of the pinhole method using a carbon dioxide (CO₂) laser to treat facial telangiectasias. This study included 155 facial telangiectasia lesions in 72 patients who visited the Kangnam Sacred Heart Hospital, Hallym University. Treatment efficacy and improvement were evaluated by quantitative measurements performed by two trained evaluators who assessed the percentage of residual lesion length using the same tape measure. Lesions were evaluated before laser therapy and 1, 3, and 6 months after the first treatment. Based on the initial lesion length (100%), the average percentages of the residual length at 1, 3, and 6 months were 48.26% (p < 0.01), 4.25% (p < 0.01), and 1.41% (p < 0.01), respectively. Complications were evaluated using the Patient and Observer Scar Assessment Scale (POSAS). The average POSAS scores improved from 46.09 at the first visit to 23.42 (p < 0.01), and 15.24 (p < 0.01) at the 3- and 6-month follow-up. No recurrence was noted at the 6-month follow-up. CO₂ laser treatment using the pinhole method to treat facial telangiectasias is a safe, inexpensive, and effective treatment that provides patients with excellent aesthetic satisfaction.

Combination of Specific Vascular Lasers and Vascular Intense Pulsed Light Improves Facial Telangiectasias and Redness

Background and objectives: Facial telangiectasias are dilated blood vessels that can represent a cosmetic issue for patients. They may be associated with other conditions, such as rosacea. Laser and light treatments are nowadays becoming a cornerstone in the management of these lesions. Materials and Methods: In total, 68 patients seeking medical treatment for facial telangiectasias were enrolled from 1 March 2019 to 1 March 2020 at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). A protocol consisting of a 1064 Nd:YAG laser for darker blue telangiectasias and 532 nm Nd:YAG for red lesions followed by intense pulsed light with an optimized spectrum for vascular lesion 3 weeks after the first procedure was proposed. A three-month follow-up visit assessed patient’s satisfaction using a visual analog scale (VAS). Two dermatologists measured clinical results using a 4-point scale, comparing pictures before treatment and at follow-up. Results: A total of 68 patients (32 males and 36 females) completed the study, performing all requested treatments. No severe side effects were reported. Patient satisfaction was very high (8.15 ± 1.05 out of a 10-point VAS scale), as well as dermatologists’ clinical evaluations (2.19 ± 0.74 out of 3). Conclusions: The combination of vascular lasers and Vascular Intense Pulsed Light acting specifically on small blood vessels may help to improve the aesthetic outcome, reducing side effects. A prospective study with a larger number of participants will be necessary to confirm this study’s findings.

Combination of Fractional CO2 Laser and Rhodamine-Intense Pulsed Light in Facial Rejuvenation: A Randomized Controlled Trial

Objective: This randomized controlled trial aims to verify the efficacy of a combined fractional CO₂ laser and rhodamine-intense pulsed-light (r-IPL) protocol in the photoaging therapy. Background: Skin aging is related to multiple environmental and genetic factors that give rise to different manifestations. In recent years many techniques have been proposed for the rejuvenation of the skin of the face such as ablative and nonablative procedures. Combination of laser or light sources with different wavelengths represents a safe and effective treatment method. r-IPL is a new pulsed-light technique capable to generate wavelengths varying from 550 to 650 nm proposed in nonablative photorejuvenation with a good efficacy and safety profile. Methods: Twenty-two patients (skin phototypes II-III, aged 46-67 years) were randomly allocated into two groups: group A was treated only with a therapeutic standard dose of the fractional CO₂ laser, whereas group B was treated with a combined therapy of r-IPL and fractional CO₂ laser. All patients were treated up to three times at a 2-month interval. Efficacy of the procedures was assessed thanks to the Fitzpatrick Wrinkle Severity Scale (scores 1-9) before treatment and at a 4-month follow-up from the last treatment. Results: Patients treated with the combination of r-IPL and fractional CO₂ laser showed better results in terms of wrinkle reduction according to the Fitzpatrick Wrinkle Severity score (2.82 ± 0.87 vs. 3.09 ± 1.14), with a statistically significant reduction in healing times (7.82 ± 0.75 vs. 13.82 ± 1.94 days, p ≤ 0.001) and duration of post-treatment erythema (3.55 ± 0.93 vs. 8.18 ± 1.47 days, p ≤ 0.001). Patient satisfaction was higher after combined fractional CO₂ laser and r-IPL treatment. Conclusions: Our data suggest that combined use of fractional CO₂ laser and r-IPL may lead to excellent results in terms of skin rejuvenation with a simple post-treatment management and an optimal tolerability.

Clinical efficacy of 595-nm pulsed-dye laser in treatment of childhood facial spider nevi: a retrospective study of 110 patients

Background:

Spider nevi (SN) are quite common in children. SN are treated via different techniques, and complete removal often requires multiple treatments. However, few studies have evaluated the treatment of SN. The present study aimed to evaluate the therapeutic effect and safety of a 595-nm pulsed-dye laser (PDL) for treating facial SN in children.

Methods:

A total of 110 children aged 0.2 to 12 years with facial SN were treated with a 595-nm PDL in a single institution from January 2016 to February 2018. In accordance with the treatment method, the patients were retrospectively divided into the small-spot-combined-with-large-spot group (SL-group) and the large-spot group (L-group). Patients with poor therapeutic results were re-treated every 6 weeks until the lesions disappeared. The minimum follow-up period was 1 year. The groups were compared using independent-samples t tests, Mann-Whitney U test, Chi-square test, and Fisher exact probability test.

Results:

The therapeutic efficacy was significantly higher in the SL-group than in the L-group, with clearance rates of 90.9% and 53.0% after the primary treatment, respectively (χ² = 17.937, P < 0.001). For skin lesions with a central spider body diameter ≥1 mm, the once-treatment cure rates were 100% in the SL-group and 34.8% in the L-group (χ² = 20.780, P < 0.001). For skin lesions with a central spider body diameter <1 mm, the once-treatment cure rates were 82.6% in the SL-group and 62.8% in the L-group (χ² = 3.961, P = 0.138). The rates of adverse reactions and recurrence did not differ between the two groups (P = 0.141 and P = 1.000, respectively).

Conclusions:

The 595-nm PDL might be a safe and effective treatment option for facial SN in children. The small-spot-combined-with-large-spot method is especially suitable for SN with a central spider body diameter ≥1 mm.
