This study found that arylsulfatase enzymes in hair follicles can convert the active form of minoxidil back to its inactive form, potentially affecting its effectiveness in treating androgenetic alopecia.

This study developed a precise and reliable UV spectrophotometric method for determining finasteride concentration in bulk and tablets, demonstrating strong linearity and accuracy.

In this study, researchers found that 2 out of 9 analyzed cosmetic hair growth products contained the banned substance minoxidil, demonstrating the presence of this antihypertensive drug in some cosmetics despite regulations.

This study found that Hydroxypinacolone Retinoate (HPR) may alleviate UV-induced skin photoaging by enhancing collagen synthesis, reducing degradation, and modulating inflammatory and oxidative responses in a dose-dependent manner.

This case report describes a child with hypopigmented mycosis fungoides successfully treated with UVA1 light therapy.

This study suggests that UVA-responsive nanocapsules may provide an effective method for skin antisepsis by releasing ethanol and reducing microorganisms within hair follicles on ex vivo porcine ear skin.

This study found that, despite confirming MC1R expression and functional cAMP signalling, α-MSH treatment did not alleviate UVA-induced stress in adult dermal fibroblasts, suggesting that α-MSH-MC1R may not directly protect against UVA-induced photoaging in these cells.

UVA exposure slows skin wound healing, but α-klotho can reverse this effect.

This study found that inhibiting the ATR kinase with VE-822 impairs DNA repair capability in quiescent human keratinocytes exposed to solar-simulated UV radiation, suggesting ATR's critical role in facilitating effective DNA damage repair and cellular recovery under UV stress conditions.

This letter discusses the use of UVA-1 in the treatment of alopecia areata but reports no new clinical results.

This study found that high-dose UVA-1 therapy appeared to improve both patient-reported outcomes and objective clinical measures in patients with morphea and systemic sclerosis, supporting its potential efficacy for treating scleroderma.

UVA exposure worsens hair loss by activating a specific cell pathway.

This study found that topical alpha-terthienyl combined with UVA radiation rapidly induced dose-dependent cutaneous photosensitization in guinea pigs, suggesting potential for photochemotherapy in skin disorders without future carcinogenic risks.

This study found that using a combination of iontophoresis and liposomal delivery facilitated the effective intradermal administration of superoxide dismutase in rats, reducing oxidative skin damage from UV exposure.

This study developed and validated a UV spectrophotometric method for accurately measuring finasteride and tamsulosin in solutions and tablets, demonstrating good sensitivity and precision.

This study validated an HPLC-UV method to detect minoxidil in cosmetic products and found that 2 out of 9 analyzed products contained minoxidil, despite international regulations banning its inclusion due to potential systemic absorption.

This study found that applying topical thymidine dinucleotide (pTT) to newborn mice before UV exposure delayed and reduced melanoma development compared to untreated controls.

This study found that extracellular ATP released from UVB-irradiated keratinocytes promotes melanin production through the P2X7 receptor, indicating a role for ATP-P2X7 signaling in UV-induced melanogenesis.

This study developed a highly sensitive fluorescent assay for measuring enzyme activity in single hair follicles, allowing the efficient analysis of over 100 samples per day.

This study observed that the aqueous extract of roasted Alocasia macrorrhizos tubers led to hair follicle repigmentation and reduced epidermal thickness in a murine model of Vitiligo.

This review examines the roles and benefits of chitosan in cosmetics and oral hygiene, highlighting its potential in the cosmeceutical market, but it reports no new results.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

In this review, researchers discussed recent advances in nanotechnology for topical skin applications, highlighting how nanocarriers enhance skin penetration and targeting in treatments for diseases like melanoma and psoriasis, while acknowledging that the penetration mechanisms and health impacts of nanoparticles remain not fully understood.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This article reviews factors influencing hair aging and available treatments like minoxidil and finasteride for androgenetic alopecia but reports no new clinical results.

This review discusses factors affecting hair aging and the current pharmacological treatments for androgenetic alopecia, mentioning topical minoxidil and oral finasteride, but does not present new clinical findings.

This study developed a new HPLC method for detecting prohibited substances like minoxidil and hydrocortisone in cosmetic products, achieving high sensitivity and successful application to real-world samples.

This study found that loading CoQ10 into a protransfersomal emulgel improved its stability and anti-ageing effects in UV radiation skin-aged induced-mice, without causing skin irritation.

This study found that applying superoxide dismutase (SOD) gel on mice protected against hair graying caused by UV-A and psoralen exposure, suggesting photosensitization may be a factor in hair aging.

This study found that the water extract of Eclipta prostrata L. may protect skin cells against UVB-induced damage, likely due to its antioxidant properties and absorption of UVA and UVB radiation.
