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.

Fractionated laser therapy, especially erbium-glass laser, effectively increases hair thickness in people with hair loss but doesn't increase the number of hairs.

This study determined that low-level light therapy and fractional lasers are effective and safe treatments for androgenetic alopecia, especially when combined with other agents like minoxidil, PRP, or growth factors.

This study found that radiofrequency treatment, with or without hydrolyzed collagen, increased dermis thickness, neocollagenesis, and FGF2 overexpression in rat skin tissue.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

This study evaluated the effectiveness of a 675 nm laser device on facial acne scars in patients with darker skin types, finding that 67% reported excellent improvement and 33% reported good improvement, with significant enhancements in skin texture and appearance after five treatments.

The book is a detailed guide for plastic surgeons with clear explanations and is recommended for both new and experienced practitioners.

This chapter reviews classification and techniques of surgical therapies for treating stable, recalcitrant vitiligo, highlighting their role alongside non-surgical methods for small, specific cases.

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.

Laser and light therapies can help regrow hair but need more research for best results.

This study found that the cytokine-mediated signaling pathway is the primary pathway disrupted in skin after CO2 laser surgery.

This study found that HERC6 and its neighboring genes play a significant role in the cellular response of human skin to CO2 laser therapy, highlighting key biological processes related to gene expression changes post-treatment.

In this study, researchers observed significant clinical improvement and patient satisfaction in the treatment of androgenic alopecia with a 1927-nm thulium laser, noting no adverse events and minimal pain across a short-term evaluation of ten patients.

This review discusses the cosmetic applications of platelet-rich plasma in dermatology, highlighting its potential benefits and the need for more controlled studies.

This review discusses the varied use and inconsistent reporting of platelet rich plasma in aesthetic surgery, finding that current studies lack consistent methodologies and objective evidence, and reports no new clinical results.

Platelet-rich plasma therapy helps improve atrophic acne scars.

This review investigates laser-induced Koebner-related reactions and highlights how different laser types, targets, and session frequencies affect the development of these skin responses, particularly in individuals with darker skin phototypes.

This study reviewed eight studies investigating transcutaneous drug delivery via fractional laser and microneedling for alopecia treatment, with six studies showing improved hair regrowth over topical therapy alone, suggesting its potential as a promising treatment strategy, although further research is needed to refine treatment parameters.

Multi-pass laser skin treatments improved healing, reduced pain, and had no major complications.

In this interventional study on female-pattern hair loss, researchers found that fractional CO2 laser therapy alone improved hair growth, as evidenced by increased hair count, thickness, density, and patient satisfaction compared to saline controls. However, the precise mechanisms behind these effects require further investigation.

This review traces the historical understanding and treatment of acne across ancient Egyptian, Greek, and Roman civilizations, but provides no new clinical findings.

Low-level laser therapy is a safe and effective treatment for hair loss.

This systematic review found that light and laser therapies, including excimer and erbium-glass lasers, generally increase hair density and diameter in various types of alopecia, with particularly notable effects in androgenic alopecia but limited efficacy in telogen effluvium.

This article reviews treatments focused on stimulating collagen synthesis and improving skin appearance through methods like mechanical dermabrasion and laser surgery, but it reports no new clinical results.

This chapter explains the mechanisms of facial aging and evaluates non-surgical treatments like thread lifts, platelet concentrates, high intensity focused ultrasound, and radio frequency for addressing aging signs, highlighting their potential for excellent patient outcomes.

This study concluded that combination therapies often yield better results for treating atrophic post-acne scars than single treatments.

Laser technologies improve medical treatments and outcomes.

This article discusses the Columbia Manual of Dermatologic Cosmetic Surgery but provides no research results.

This study observed that both PRP and 1550 nm fractional erbium-glass laser improved AGA, with greater hair density in patients receiving the combination therapy and no side effects reported.

The study's findings are unreliable due to retraction.
