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

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 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 study observed that using fractional CO2 laser-assisted delivery of clobetasol propionate cream significantly improved treatment outcomes for localized alopecia areata compared to the cream alone, suggesting the laser's enhancing effect on hair regrowth.

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.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

Fractional infrared technology is effective and safe for treating cervical laxity.

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.

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 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.

Combining microneedling with Q-switched laser treatment for tattoo removal did not improve results and caused more pain.

Laser treatment shows promise for hair growth, but needs further research.

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 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.

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, 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 article contains no new research findings or results.

This narrative review highlights recent advancements in anti-ageing cosmetic procedures, emphasizing personalized interventions that improve patient outcomes and quality of life. The review synthesized evidence from 144 articles to assess the effectiveness and potential side effects of surgical and non-surgical techniques for facial rejuvenation.

This study's network meta-analysis reported that botulinum injection combined with red laser and topical minoxidil is most effective for increasing hair density in androgenetic alopecia when using low-level laser therapy.

Radiofrequency devices effectively tighten skin without surgery.

This study found that radiofrequency microneedling is effective and well-tolerated for improving various skin conditions, showing comparable efficacy to fractional lasers for atrophic acne scars with generally favorable patient satisfaction and safety.

Using lasers to deliver minoxidil can potentially improve its effectiveness in treating male pattern hair loss.

This study concluded that 12 sessions of fractionated thulium laser treatment improved hair density and thickness in patients with pattern hair loss, with further benefits from adding a growth factor solution post-treatment.

This study found that treating patchy alopecia areata with fractional CO2 laser and topical triamcinolone acetonide was more effective and safer than intralesional triamcinolone, despite higher initial discomfort, as it resulted in greater patient satisfaction and fewer adverse effects like skin atrophy.

In this study, the combination of CO2 fractional laser therapy with Bimatoprost 0.03% was found to be more effective in promoting hair regrowth in Alopecia Areata patients than laser therapy alone, with higher response rates and minimal adverse effects reported.

In this review, the researchers highlight LED therapy as an emerging and safe treatment for skin inflammatory conditions, aging, and hair growth disorders, noting its integration into dermatological practice but emphasizing the need for more controlled studies to confirm its efficacy.

This review found that microneedling appears to be a safe and effective option for treating scars and wrinkles, with fewer side effects and shorter recovery time than some other treatments.
