“…The effectiveness of hair removal with the long-pulsed 755 nm alexandrite laser was first described by Finkel et al 13 Since then, many studies have confirmed the efficacy and safety profile of this device, [14][15][16][17] with a median hair reduction rate of 70% to 96%. 8,10 According to literature data, our patients showed an average hair reduction of 87% In a prospective study by Garcia et al 19 In the literature, many uncommon alexandrite side effects have been reported, including purpura, 24 Interestingly, our study showed a significant improvement of PFC in all our patients. PFC is a chronic inflammatory condition that is triggered by aberrant hair growth in regions that are subject to traumatic hair removal.…”

Lasers are considered the most efficient methods for hair reduction. The goal of these devices is to provide long-term effects without adverse reactions. This is a randomized split-body controlled study on body hair removal and pseudofolliculitis (PFC) treatment, comparing the standard single pass (SP) emission with the multipass emission (Moveo handpiece) with 755 alexandrite laser. Patients with Fitzpatrick skin types I to VI underwent laser hair removal, by treating one side of the body using the standard SP and the other side with Moveo. Treated areas included face, arms, legs, trunk, axillae and groins. Each patient underwent a minimum of three to a maximum of eight treatments, every 6 weeks, with a 6-month follow-up. Hair reduction, side effects, PFC severity score and patient satisfaction were recorded for all patients. Totally, 108 patients were enrolled, of whom 96 were female. The overall hair reduction rate (% ± SD), independent of skin type, was estimated as 87 ± 5.5 for standard SP and 78.5 ± 7.6 for Moveo. No significant statistically differences were found between the two groups. Side effects included pain, which was higher after standard SP (4.2 ± 0.8) than after Moveo treatment (1.5 ± 0.5). A statistical significant difference between the two devices was found (P = .0002). PFC score improved in almost all the patients. Patients declared to be satisfied with both the treatments, reporting a preference for Moveo (84% vs 16%) (P = .01). Standard SP and Moveo 755 alexandrite laser seems to be safe and effective treatments for hair removal in all Fitzpatrick skin types and for PFC. Moveo has a higher security profile with fewer side effects.

“…In the literature, many uncommon alexandrite side effects have been reported, including purpura, 24 paradoxical hypertrichosis, dry skin, allergic/chemical skin reaction, accelerated skin aging, induction or aggravation of acne, rosacea‐like rash, and pigmentary changes of pre‐existing nevi 25 . None of them was found in our patients.…”

Key Clinical MessageThis study highlights the first documented cases of angiokeratoma of Fordyce following laser hair removal (LHR) emphasizing the importance of patient selection and careful laser use. It underscores the importance of understanding LHR‐associated risks, particularly for patients with darker skin. The efficacy of topical rapamycin as an alternative treatment for angiokeratomas is also discussed.AbstractLaser hair removal (LHR) has emerged as a widely accepted method for achieving long‐term hair reduction. While generally considered safe, it is important to study the possible adverse events to optimize patient care. Here, we present a unique case report of angiokeratoma of Fordyce, a rare vascular lesion, following LHR. Two patients experienced the development of these lesions subsequent to LHR treatment sessions, characterized by a severe burning sensation during the procedure. Interestingly, both individuals exhibited varicose veins on their legs, suggesting a potential risk factor for this complication. Our findings highlight the importance of understanding the mechanisms underlying LHR‐induced adverse events and the need for further research to elucidate associated risk factors and management strategies. This case report serves to enhance awareness among clinicians and emphasizes the significance of patient counseling regarding the potential side effects of LHR.

“…The literature reports on such adverse effects and complications resulting from the use of an Alexandrite laser as: paradoxical hyperkeratosis and discoloration and post-inflammatory discoloration, de-novo growth of hair outside the area treated by laser, potentiation of co-existing vellus hair in the treatment area, induction or aggravation of acne, rosacea-like rash, premature greyness of hair, tunnelling of hair under the skin, prolonged diffuse redness and enema of the face, focal hypopigmentation of the lip, angular cheilitis, purpura and inflammatory and pigmentary changes of pre-existing nevi. [15][16][17][18][19][20][21][22][23] Research on cooling sapphire handpiece Alexandrite reports no severe side effects. 19 The literature also provides information about side effects using Ng-Yage Q switched and ruby lasers.…”

“…27 The scientific literature presents numerous reports on the effectiveness of LHR but is limited to different parts of the body and no reports on mixed-race participants have been found. 6,8,10,11,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] Objective The authors of this study have noticed that mixed-race patients' skin reacts differently than similar skin types according to the Fitzpatrick scale of non-mixed-race patients and so far no related research was found. The objective of the study was to investigate the occurrence and types of side and adverse effects after performing diode laser 805 nm hair removal in a group of mixed-race participants with phototypes III-V and to assess its impact on the results of the treatment measured as a percentage of hair reduction in the treated area.…”

Introduction: Laser hair removal (LHR) has become one of the most popular treatments in aesthetics. Side effects are an inevitable part of laser therapy, therefore managing them is crucial for every laser practitioner to ensure patients’ safety along with achieving the best results. The available references describe the effectiveness of the diode LHR for all skin types according to the Fitzpatrick scale, but the question of patient safety and minimization of side effects and postoperative complications in mixed-race patients remains unanswered. This study aims to illustrate aspects of specific side effects in patients of mixed ethnicity and the impact of those effects on the results of the treatment. Methods: The study was conducted in Poland and the United Kingdom on 216 patients of various ethnic backgrounds. This study analyses the frequency of side effects in a mixed-race group of 32 participants, taking into account their skin type according to the Fitzpatrick scale. The patients received a course of 6 treatments using diode laser 805 nm. An objective and a subjective method were used to analyse treatment results and side effects, with adverse effects documented, if observed. Treatment settings were adjusted to skin reaction during the patch test. Results: Objective analysis was different from the subjective analysis of the treatment’s effectiveness. No adverse effects were observed. Side effects such as hyperpigmentation, skin irritation, skin burns, and skin hypersensitivity were found. Conclusion: 805 nm diode laser is effective and efficient at hair removal in mixed-race patients. It is a safe treatment in terms of skin reaction as only short-term side effects were observed in the treated area and no adverse effects were noted. To achieve the best results and to avoid adverse effects it is necessary to adjust treatment settings according to the individual patient’s skin reaction.
