This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

In this study, researchers found that specific treatment parameters disrupted follicles and sebaceous glands, damaging the bacteria Cutibacterium acnes and promoting follicular remodeling, which may improve both inflammatory and noninflammatory acne lesions.

This study reviewed 44 clinical trials and found that home-based laser devices are effective for short-term hair removal and skin rejuvenation, with common side effects including erythema and edema; additional trials are needed to confirm safety and efficacy.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

Laser hair removal is generally effective, with results varying by laser type and patient.

In this study, a triple wavelength laser was found to be highly effective and well-tolerated for reducing hair in Indian women with Fitzpatrick skin types III and IV, achieving an average hair count reduction of 86.5%, with only mild and transient adverse effects observed.

This narrative review discusses the evolution and diverse medical applications of laser technologies, particularly in dermatology and skin biology, without reporting new research findings.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This review details the advancements and benefits of fractional erbium:YAG resurfacing lasers for treating photoaging, acne scarring, and dyschromia, but it presents no new clinical results.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This study observed that multiphoton excitation microscopy revealed changes in vascular structure and hair papillae in mice subcutaneous tissue following cyclophosphamide treatment for chemotherapy-induced alopecia.

This article suggests that eyelash prostheses may exacerbate isotretinoin-induced blepharitis, highlighting the need for caution among young women using both products.

This study found that ruby laser hair removal causes microscopic epidermal damage but does not lead to cellular hyperproliferation, unlike ultraviolet-irradiated cell damage.

This study found that using a commercially available IPL home-use device led to significant hair reduction and demonstrated long-term efficacy in maintaining hair reduction one year after treatment.

This letter discusses the use of the 2940 nm Er: YAG fractional laser for male androgenetic alopecia but provides no new clinical findings.

Er:YAG laser therapy effectively treats Hailey-Hailey disease, leading to long-term remission and improved quality of life.

This study evaluated an 808-nm diode laser at different fluences for permanent axillary hair removal in Korean women and found that high-fluence treatment (14 J/cm2) effectively reduced hair density and thickness, with no significant difference in comfort compared to lower fluences.

This study found that while Er:YAG laser therapy can initially improve the appearance of eruptive vellus hair cysts, it was ineffective in preventing early recurrences due to limitations in ablation depth.

This abstract provides no research findings or results; it outlines services and content types available through a health publishing platform.

This article reviews light-based hair removal devices for home use, highlighting safety issues and the need for consistent international regulations and guidelines for their manufacture and marketing.

This study compared the microscopic treatment zones created by different fractional lasers and radiofrequency in swine skin, finding distinct patterns and damage levels for each technology.

This study suggests that fractional infrared technology may effectively improve cervical skin laxity by enhancing dermal thickness without adverse effects in a small pilot group.

595 nm pulsed dye laser is a cost-effective treatment for nonmelanoma skin cancer with a low recurrence rate.

This review discusses home-use laser and light skin devices for various dermatological purposes and reports no new clinical findings; the authors highlight the need for dermatologists to evaluate these devices' clinical value.

The 1540nm fractional erbium-glass laser helps treat hair loss caused by hormones.

This study found that while both professional and home-use lasers effectively reduced axillary hair, the professional Diode laser was significantly more effective, achieving 85-88% reduction compared to 46-52% with the home-use laser, which still offers some safety for users.

This article reviews the growing trend of at-home laser and light devices for treating conditions like acne, hair removal, and psoriasis, emphasizing their popularity and the need for cautious use but reports no new clinical results.

This report describes a case where solar-induced postinflammatory hyperpigmentation following laser hair removal was treated with a combination of topical treatments and serial TCA peels, resulting in only slight improvement.

In this study, using a 1064 nm picosecond Nd:YAG laser effectively removed undesirable scalp micropigmentation in four patients within 1–3 treatment sessions, with no unexpected adverse events reported.

This overview highlights the effectiveness of fractional lasers, particularly fractional erbium:YAG, in treating various skin conditions with customizable settings and a short recovery time, while noting potential risks and the importance of tailored applications for different skin types.
