This study found that fractional CO(2) laser treatments led to significant improvements in eyelid skin tightening and eyebrow elevation over one year, with no significant side effects reported.

This study found that ginsenoside Rb1 treatment significantly reduced aging symptoms in mice by regulating cell cycle and apoptotic pathways, potentially linked to metabolic changes.

In a C3H mouse model, this study found that topical retinoids can significantly alter hair-cycle dynamics by prolonging the anagen phase and shortening the telogen phase, a reaction connected to increased cellular retinoic acid-binding protein levels.

This study reports that an intervention decreased glucose and insulin levels, indicating improved insulin resistance, which is linked to a skin condition called acne vulgaris and other disorders associated with insulin resistance.

This study identified a new subset of Ret-positive sensory neurons involved in itch perception, characterized by their unique expression profile and response to specific itch-inducing molecules.

In this study, Ritlecitinib was reported as a newly approved treatment for alopecia areata that can be used in patients aged 12 and older; after 24 weeks, it resulted in 80% or more scalp hair coverage in treated patients compared to a placebo.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

In this study, KeraGLO, a nutritional supplement with hydrolyzed keratin, was shown to significantly improve skin wrinkle depth, smoothness, moisture, firmness, and hair health in healthy adult females over a 90-day period at both 500mg and 1000mg doses compared to baseline.

This study reports that combining ergothioneine, collagen peptides, and sodium hyaluronate improved skin parameters like hydration, elasticity, and wrinkle reduction in Chinese women, while ex vivo data indicated enhanced antioxidant action and structural support, suggesting potential for anti-aging nutricosmetics.

Retinoic acid receptors are important for hair follicle development.

In this study, recombinant type III collagen was found to promote fibroblast proliferation and migration, suggesting potential anti-aging and repairing effects, although it was only effective in significantly inhibiting IL-6, not TNF-α, secretion.

This study found that in Asian patients aged 12 and older with alopecia areata and significant hair loss, ritlecitinib showed clinical efficacy in improving hair regrowth and eyebrow and eyelash scores over 48 weeks, with an acceptable safety profile observed throughout.

This study reported that using autologous micro-grafts according to the Rigenera® protocol may improve hair restoration and increase hair follicle numbers in patients with androgenetic alopecia after 6 to 9 months.

In this study, researchers found that IGFBP‐rP1 levels were lower in individuals with androgenic alopecia compared to healthy controls, and subcutaneous injection of IGFBP‐rP1 showed potential in slowing hair loss progression in a mouse model by affecting the hair cycle transition.

This study found that oral setipiprant was safe but did not improve scalp hair growth compared to placebo in men with androgenetic alopecia.

In this study, iL-PRF injections produced significantly better clinical scores for androgenetic alopecia patients compared to controls, especially in those with more severe baseline conditions.

This study evaluated the effects of autologous micrografts for androgenetic alopecia, reporting moderate improvements in hair loss reduction and hair density among most patients after treatment, with satisfactory results noted in patient satisfaction and treatment tolerability.

This study found that using Alastin Restorative Skin Complex Serum 2.0 with TriHex Technology for 12 weeks significantly improved facial skin hydration, elasticity, and overall quality in individuals with moderate to severe skin aging, with histological evidence showing new collagen and elastin fibers.

In this study, patients with alopecia areata who didn't initially respond to ritlecitinib at Week 24 showed improved response rates by Week 48, with up to 34% achieving better hair regrowth outcomes.

HA-iMSC-EVs can improve skin aging by boosting cell growth and restoring collagen and elastin.

This review discusses the therapeutic potential and safety of bioidentical recombinant human epidermal growth factor (rhEGF) for various skin and mucosa conditions and reports no new clinical results.

This study found that lipid and acne inhibitive cream improved the skin condition in a rabbit ear acne model, showing significant changes in follicular cornification.

This study found that ion-paired solutions significantly improved the skin penetration of risedronate in hairless mice compared to risedronate alone.

This source describes SH‑1 as a next-generation androgen receptor antagonist designed for localized treatment of androgenetic alopecia, aiming to reverse follicular miniaturization while maintaining endocrine balance. Unlike traditional therapies, SH‑1 offers tissue-specific action, avoiding systemic effects.

This study found that the proteins Par3, mInsc, and Gαi3 cooperate to regulate LGN polarization and promote perpendicular cell divisions during murine epidermal morphogenesis.
