This study found that sinapic acid demonstrated antioxidant and anti-inflammatory effects against UVB-induced damage in human keratinocytes, suggesting its potential as an anti-aging cosmetic ingredient.

This review found that hormonal therapies, including FDA-approved combined oral contraceptive pills and spironolactone, are effective and well-tolerated treatments for acne vulgaris in adolescents with or without endocrine disorders, providing alternative options to antibiotics.

This review discusses various treatments for adult acne in women, including topical, systemic, and alternative therapies, and reports no new clinical results.

New acne treatments include combination creams, advanced retinoids, and light therapies, focusing on safety and patient adherence.

This study found that 1,2,3,4-tetrahydroquinoline derivatives, particularly N-methyl-7-amino-1,2,3,4-tetrahydroquinoline, may be excellent blue dye candidates for human hair, offering superior color purity, stability, and fastness compared to 2,3-dihydroindoles.

This review provides guidelines for physicians on using hormonal therapies, such as androgen receptor blockers and oral contraceptives, to treat hormonally related acne, but reports no new clinical findings.

This study demonstrated that human hair keratins have strong antioxidative properties, providing protection against oxidative stress in human dermal fibroblasts, suggesting their potential as antioxidizing supplements.

This article describes adult female acne as a complex condition affected by genetic, hormonal, and environmental factors, with hormonal therapies highlighted as particularly valuable for treatment.

This analysis examines acne vulgaris using an integrative approach, highlighting its links with psychopathology, lifestyle, and diet, but reports no new results.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

This study presents a novel optical microscopy technique showing that biomagnetic fields in hair follicles can interact with those in blood, affecting magnetic profiles until catalase breakdown.

This review discusses recent developments in dermatological treatments for skin conditions such as acne, psoriasis, acute inflammation, and alopecia but reports no new clinical results.

This study found that in Arabidopsis, the CLE14 peptide regulates root hair growth by promoting elongation, an effect that requires CLV2 and CRN proteins and involves ethylene signalling along with hydrogen peroxide and nitric oxide pathways.

This study found that when human hair follicles are immersed in hydrogen peroxide, the resulting oxygen bubbles indicate catalase activity, and their absence may suggest tissue death.

The researchers reported that corticosteroid treatments for alopecia areata led to clinical improvement but did not significantly alter oxidative stress markers, suggesting a limited regulatory effect on these systems.

In this study, Allium hookeri extract increased viability and size of dermal papilla cell spheroids and reduced oxidative stress effects, potentially promoting hair growth by regulating specific protein signaling pathways in human cells.

In this rat study, subcutaneous injections of hydrogen peroxide and cumene hydroperoxide appeared to completely prevent chemotherapy-induced hair loss by inducing cell cycle arrest, suggesting a novel approach to help cancer patients maintain their quality of life during treatment.

In this study, a 63-year-old male with chronic acne necrotica achieved complete clinical remission using topical erythromycin and benzoyl peroxide.

This study reported that CoFe2O4 magnetic nanoparticles efficiently catalyzed the synthesis of minoxidil from 2,6-diamino-4-chloro-pyrimidine N-oxide, achieving a 95% yield with sustained reusability.

This preliminary study found that Melandrium firmum extract may promote hair growth and inhibit 5α-reductase, suggesting potential as a candidate for treating androgenetic alopecia.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

This article reviews the historical and scientific perspectives on the phenomenon of stress-induced changes in hair color and reports no evidence supporting the idea that holding or resigning from political office accelerates human aging or hair graying.

In this study, researchers reported that acne is a complex and chronic skin condition most commonly affecting individuals aged 11 to 30, with more severe cases observed more frequently in men and areas rich in sebaceous glands like the face, back, and chest.

This review covers hair dye formulations, their mechanisms, and potential applications, but reports no new findings; the authors highlight the process of oxidative dyeing and repairing damaged hair.

Melatonin helps broccoli roots produce anti-cancer compounds by controlling nitric oxide and hydrogen peroxide levels.

This review concludes that exogenous hydrogen peroxide, rather than UV light, is likely the key factor in the development of cutaneous melanoma in swimmers, as it can penetrate water-submerged hair follicles.

In this study on cultured human dermal papilla cells, researchers found that niacinamide may enhance hair growth by reducing oxidative stress-induced cell senescence and delaying catagen entry, suggesting potential applications against hair loss.

This paper introduces a new understanding that the human hair follicle medulla lacks metabolic activity for H2O2 breakdown, indicating that H2O2 decomposition occurs primarily in the cortical areas.

This manuscript suggests that exogenous hydrogen peroxide is a primary risk factor for higher incidence of cutaneous melanoma in swimmers, with UV radiation playing a secondary role.

This article discusses the classification of acne lesions and emphasizes the importance of evidence-based treatment and nursing care, without presenting new research results.
