This study found that POD-loaded solid lipid nanoparticles using 0.5% poloxamer 188 and 1.5% soybean lecithin (P-SLN) improved epidermal targeting and POD accumulation in porcine skin compared to traditional tincture.

This article discusses the treatment considerations for a 17-year-old boy with a six-month history of acne but reports no new research findings.

This study found that sebum free fatty acids may enhance the antibacterial defense of human sebaceous glands by upregulating the expression of the antimicrobial peptide hBD-2, potentially aiding in acne treatment.

This review summarizes recent research on the skin microbiome's role in acne development and how antibiotic treatments affect skin microbes, but it reports no new clinical results.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

Long-standing benign tumors can become cancerous, especially in people with weakened immune systems.

In this study, oxidation hair dye formulations tested on mice showed no evidence of causing systemic toxicity or cancer over an 18-month period.

This article reviews the hormonal and medication-related factors associated with acne development but does not present new research findings.

This study found that mTOR gene expression was significantly increased and S6K1 activation was observed in skin samples from acne patients compared to healthy controls, suggesting mTORC1's involvement in acne pathogenesis.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This study found that minoxidil is bioactivated through sulfation by the phenol-sulfating form of phenol sulfotransferase in human liver.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

Mutations in the ACTB gene cause Becker’s nevi and may lead to muscle issues in Becker’s nevus syndrome.

This study identified distinct human and bacterial protein profiles in sebaceous follicular casts, with acne samples showing proteins linked to inflammation and normal samples showing proteins involved in stress protection.

This review discusses various sampling methods for studying Propionibacterium acnes in skin follicles and reports no new experimental results; the authors evaluate these methods' strengths and limitations.

This study concluded that the 800-nm diode laser is effective in enhancing skin structure and collagen expression via the TGF-β/Smad pathway, suggesting potential for non-ablative rejuvenation.

This study found that daily consumption of soft drinks significantly increases the risk of moderate-to-severe acne in adolescents, particularly if sugar intake from these drinks exceeds 100 grams per day.

The researchers found that plant extracts from Papaver rhoeas L., Clitoria ternatea L., and Carthamus tinctorius L. are effective natural cosmetic dyes, offering intense and stable colors without cytotoxicity.

This review discusses the need for an updated 'European hair cosmetic series' to include common contact allergens and remove outdated substances based on current evidence and regulations, but it reports no new results.

This study introduced a bioengineered model that simulates acne's microenvironment in mice, enabling the exploration of host and P. acnes interactions and presenting a novel platform for anti-acne drug and vaccine screening.

In this study, hair damaged by permanent dye showed signs of recovery over time, with near complete restoration to its original state after eight weeks.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.

This observational study aims to more accurately detect and localize Propionibacterium acnes in acne lesions by combining multiple microbiological visualization techniques, but it does not present new results on their causality to acne.

This study found that 9% of tested patients had positive patch test reactions linked to hair care products, with most reactions clinically relevant and commonly involving allergens like p-phenylenediamine.

This study demonstrated that human hair shafts can inhibit the growth of Gram-positive bacteria but have no effect on Gram-negative bacterial growth, offering insights into hair and scalp health.
