This study observed that a combination of micro-needling and low-level light/laser therapy significantly increased hair density in patients with mild to moderate androgenic alopecia, showing an increase of 12 hairs/cm² after 16 weeks, compared to baseline.

This study found that low-level laser therapy effectively reduced relapse rates, while functional appliances did not; combining them offered no additional benefits.

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 found that combining Fractional CO2 laser with platelet-rich plasma led to better improvement in vitiligo treatment compared to platelet-rich plasma alone, based on patient satisfaction and lesion size reduction.

This study found that repetitive 532 nm laser therapy significantly decreased scores for macules, pigmented, and vascular lesions on the facial area, regardless of skin phototype or age.

This study found that non-ablative Er:YAG laser treatment, alone or combined with other therapies, effectively improved hair quality and reduced AGA grade in patients, with high satisfaction reported and no adverse reactions.

In this study using mice, fractional CO2 laser therapy promoted hair regrowth by inducing moderate inflammation, enhancing VEGF-mediated angiogenesis, and activating the Wnt10b signaling pathway.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

This study found that among young patients with acne vulgaris, combining a 675 nm red-light laser with isotretinoin led to more rapid and pronounced improvement in lesion severity compared to laser treatment alone, without adverse events.

Low-level laser therapy reduces pain, swelling, and improves healing after wisdom tooth removal.

This study introduced a novel microscopy system using an Er3 + −doped femtosecond fiber laser, achieving detailed imaging of biological structures in plant and skin samples with improved spatial resolution for various applications, including in vivo imaging.

This study found that low-level laser stimulation activates the Wnt signaling pathway, promoting hair follicle stem cell regeneration and accelerating wound healing.

In this study, low-level laser therapy significantly improved the mechanical strength of bone at tooth extraction sites in rats, while neither platelet-rich plasma alone nor combined with laser affected mechanical strength or calcium content.

This study found that using a combination of ablative CO₂ fractional laser and fetal fibroblast transplantation significantly reduced scarring in mice, with long-term sphere-forming cultured fibroblasts producing scar appearances closest to normal skin.

This study found that low-level laser therapy significantly increased hair counts in women with female pattern hair loss but not in those with telogen effluvium, without serious adverse events.

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.

This study found that pulsed diode laser treatment safely and effectively cleared lesions and reduced the appearance of dark plugs in trichostasis spinulosa for up to 20 weeks in dark-skinned individuals.

This case report describes promising results in treating poliosis circumscripta with exosomes and fractional picosecond laser, showing significant hair regrowth and repigmentation, though spontaneous repigmentation cannot be ruled out.

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

This study reports three cases of alopecia areata resistant to corticosteroids that improved after 16 weeks of treatment with a combination of fractional carbon dioxide laser and topical tacrolimus, suggesting a potential new therapeutic option that requires further confirmation.

This case study reports that treating a female patient with facial partial unilateral lentiginosis using a 532-nm Nd:YAG fractional picosecond laser resulted in significant improvement in pigmentation without notable side effects, indicating it may be an effective and well-tolerated treatment option.

This case report observed that resection of a lesion using a carbon-dioxide laser in a Labrador retriever with lingual hair heterotopia led to positive outcomes, although hair partially regrew.

In this case study, a 55-year-old male with a history of hypospadias repair developed urinary complications due to urethral hair bezoars, and the researchers reported that transcutaneous ND:YAG laser epilation effectively removed urethral hair, preventing recurrence of such issues.

The study found that CO2 dot matrix laser combined with platelet-rich plasma improved scar repair, psychological state, and quality of life in patients with acne vulgaris-related depressed scars.

This review discusses Graham-Little Piccardi-Lasseur syndrome, a rare dermatosis with limited treatment options, emphasizing the importance of early diagnosis through physical exam and dermoscopy, but reports no new results.

This study reports that combining microneedling with low-intensity laser therapy appears to be a safe and effective treatment for androgenetic alopecia, as indicated by a literature review.

This study observed that PRP treatment resulted in greater improvement in hair thickness and density in alopecia areata patients compared to LLLT, with benefits sustained over 12 weeks.

This study found that ablative fractional laser treatment significantly alters gene expression related to skin rejuvenation, enhancing wound healing and tissue regeneration processes, and suggests multiple treatments may maximize these effects.

This study observed that five cases of primary cicatricial alopecia showed an excellent response to a combination of oral zinc and long-pulsed Nd:YAG 1064-nm laser treatment, suggesting this approach may be beneficial for certain types of this condition.

This study found that combining topical capislow with laser hair removal significantly enhanced hair reduction compared to laser alone, although the beneficial effects lasted only while capislow was applied.
