This study found that Er–YAG laser treatment significantly enhanced skin absorption and follicular delivery of antialopecia drugs, suggesting a potential laser-assisted approach to treat alopecia.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

This literature review suggests that fractional laser therapies may positively impact hair regrowth in androgenic alopecia, though current evidence is mostly limited to small studies and case reports, highlighting a need for more comprehensive randomized controlled trials to confirm their efficacy and safety.

This study developed a novel regenerative platform using nanozyme-enabled materials combined with exosomes and laser stimulation to enhance wound healing in a mouse model, which more effectively regulated reactive oxygen species and improved early angiogenesis and collagen organization compared to conventional methods.

This review highlights the various cosmetic and therapeutic applications of laser technologies in dermatology, discussing the mechanisms, safety, efficacy, and recent advancements to provide a comprehensive overview of their uses and potential future implications.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

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.

This literature review suggests that fractional lasers and microneedling, particularly when used with topical agents, may be effective treatments for alopecia areata; however, the small size and number of studies highlight a need for larger trials to confirm efficacy.

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 review evaluates laser therapy for alopecia areata, noting that fractional lasers facilitate hair growth and drug delivery, but reports no new clinical results.

This review discusses five popular resurfacing technologies for facial rejuvenation, highlighting their role in achieving smoother, healthier, and younger-looking skin, and reports no new clinical results.

This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.

This review discusses the effects of low-level laser therapy in various biological processes for wound healing and tissue repair and reports no new results.

In this study, researchers evaluated the efficacy of a collagen booster used alongside CO2 fractional laser treatment for skin aging, finding that the combination treatment affected the vascularization and healing process of the skin on a healthy adult's forearm.

This study found that low-level laser therapy may enhance wound healing and reduce pain, swelling, and inflammation by increasing mitochondrial activity and oxidative stress, leading to greater protein synthesis and cell proliferation.

The study suggests that CO₂ laser creates hair transplant channels with significantly less lateral thermal damage than Ho:YAG laser in the human scalp.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This review found that most studies support the effectiveness and safety of using hyaluronic acid fillers and laser treatments together for facial rejuvenation, but highlights that the evidence is limited to small, nonrandomized studies and additional research is necessary.

This study found that combining fractional erbium-glass laser therapy with topical minoxidil significantly improved hair density and diameter in men with androgenetic alopecia compared to using minoxidil alone over a 24-week period, with no serious adverse events reported.

This study found that 1,540 nm fractional erbium-glass laser treatment combined with topical minoxidil significantly increased hair regrowth in alopecia areata patches compared to minoxidil alone, with response rates of 60% versus 16%, though the long-term effects remain unknown.

This study found that combining fractional CO₂ laser with halometasone cream improved chronic eczema more effectively than halometasone alone, with efficacy varying by laser parameters and showing better results at 4 weeks compared to 1 week. Pain was noted with higher energy treatments.

This abstract describes the use of lasers in hair transplantation for creating recipient sites and enhancing hair growth but reports no new findings.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

Channels stay open for 24 hours, making laser treatment potentially effective for hair loss.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

This study found that 1,550-nm Er:Glass fractional laser treatment increased hair density and shaft diameter in patients with androgenetic alopecia, but did not up-regulate Wnt10A and IGF-1 mRNA expression.

This article reviews potential causes for angiolymphoid hyperplasia with eosinophilia, a benign vascular tumor often found in middle-aged adults, and reports no new clinical findings.

This source highlights that fractional CO2 laser, as a minimally invasive technology, shows significant benefits in treating various skin and mucosal conditions by improving therapeutic outcomes, shortening recovery times, and enhancing precise personalized interventions through emerging technologies like AI and biomarker monitoring.

In this study, both topical clobetasol propionate and fractional Er: YAG laser followed by topical steroids demonstrated significant improvement in patients with alopecia areata, but the combined laser and steroid treatment was found to be more effective and safe.

This study observed that combining nonablative fractional laser treatment with topical minoxidil led to hair regrowth in Chinese alopecia areata patients, noting complete regrowth in some patients and no relapse in the majority at a one-year follow-up, without reported side effects.
