BACKGROUND: Collagen dominates the skin's extracellular matrix (ECM). Type I collagen comprises 80%-90% of the skin's collagen, followed by type III (8%-12%) and type V (5%). Reactive oxygen species, matrix metalloproteinases, and collagen degradation all increase during photoaging, which disrupts the ECM's dynamic balance and lowers the amount of total collagen in the body. In recent years, domestic and foreign researchers have conducted multidimensional and multifaceted studies on collagen and skin photoaging...

BACKGROUND: Narrowband ultraviolet B (NB-UVB) phototherapy is the cornerstone of vitiligo treatment. Its combination with other treatments usually yields a better response. Latanoprost, a prostaglandin F2α analog, and autologous platelet-rich plasma (PRP) have been reported to be effective for vitiligo. AIM: To evaluate the efficacy of NB-UVB combined with intralesional latanoprost or PRP for stable nonsegmental vitiligo (NSV). METHODS: Sixty patients with stable NSV were recruited and randomly allocated to two equal groups...

Photodynamic therapy (PDT) is already used to treat many cancers, including breast cancer, the most common cancer in women worldwide. The destruction basis of this method is on produced singlet oxygen which is extremely reactive and is a major agent of tumor cell killing. The measurement of singlet oxygen produced within PDT is essential in predicting treatment outcomes and their optimization. This study aims to determine the optimal total light dose administered during PDT by calculating the singlet oxygen to facilitate the prediction of the treatment outcome in mice bearing 4T1 cell breast cancer...

BACKGROUND: Continuous exposure of the skin to ultraviolet B (UVB) rays can cause inflammation and photodamage. In previous studies, we observed that the upregulation of nc886, a noncoding RNA (ncRNA), can alleviate UVB-induced inflammation through suppression of the protein kinase RNA (PKR) pathway. We aim to investigate the effect of fermented black ginseng extract (FBGE), which has been shown to increase the expression of nc886, on UVB-induced inflammation in keratinocytes. METHODS: To confirm the cytotoxicity of FBGE, MTT assay was performed, and no significant cytotoxicity was found on human keratinocytes...

BACKGROUND: Light therapy is widely used in medicine. Specifically, photobiomodulation has been shown to exert beneficial effects in wound healing disorders, which present a major challenge in health care. The study's aim was providing information on the effect of a novel, red-laser-based wound therapy device (WTD) on keratinocytes and fibroblasts during wound healing under optimal and non-optimal conditions. METHODS: The scratch wound assay was employed as a wound healing model for mechanical damage with readjustment of specific cell milieus, explicitly chronic TH1 inflammation and TH2-dominant conditions...

OBJECTIVE: This survey aimed to evaluate knowledge of photoprotection among individuals from a random group in a resort town in Poland, Kołobrzeg, and explore the correlation between their knowledge and demographics like age, gender, education, and residence. METHODS: An anonymous survey was conducted among a diverse group. This population comprised individuals from various backgrounds: health spa patients undergoing treatments, therapies and medical appointments, guests visiting the resort for leisure, passersby, and staff working at the spa and recreational facilities...

BACKGROUND: Differences in clinical efficacy based on the fluence of fractional picosecond laser treatment for acne scars are unknown. OBJECTIVE: To compare the efficacy and safety of low-fluence versus high-fluence fractional picosecond Nd:YAG 1064-nm laser treatment in acne scar patients. METHODS: In this 12-week, investigator-blinded, randomized, split-face study, 25 patients with moderate-to-severe acne scars received three sessions of high-fluence laser treatment (1...

BACKGROUND: Rosacea is a chronic skin disorder characterised by abnormal neurovasculature and inflammation in the central region of the face. The efficacy of pulsed-dye laser and intense pulsed light treatments for rosacea have been demonstrated in several clinical trials. However, there is currently no research on the efficacy of long-pulsed alexandrite laser (LPAL) therapy alone for rosacea-related facial redness and its effect on skin microbiota. AIM: To evaluate the efficacy of LPAL therapy on facial redness in rosacea and assess changes in skin microbiota composition...

BACKGROUND/OBJECTIVES: Favipiravir is an antiviral agent, recently used for COVID-19 infections. Several reports associate favipiravir intake with Wood's lamp fluorescence of hair, nails, and sclera. The present study was designed to elucidate the positivity rates, and sites of favipiravir-related fluorescence and to unravel the site-specific changes in fluorescence positivity rates by a function of time past exposure. METHODS: The study population comprised 50 patients and 50 control individuals...

BACKGROUND: Vitiligo is an acquired skin disease with a worldwide prevalence of 0.5%-2% and a tendency to involve both genders. Although the exact pathologic mechanism is unknown, there is some evidence for the role of autoimmunity in this disease. Based on this theory, various immunosuppressive agents, such as topical or systemic corticosteroids and phototherapy (including narrowband ultraviolet B), are used. Methotrexate is another immunosuppressant that has recently become popular as a single treatment for vitiligo; however, the synergistic effect and its superiority over other treatments are two crucial factors that are still obscure...

BACKGROUND: Ablative carbon dioxide (CO2 ) laser is still a cornerstone in the management of xanthelasma. However, post-laser complications such as post-inflammatory hyperpigmentation or scarring have to be considered. Heparin sodium was recently suggested as an effective therapeutic modality for xanthelasma. OBJECTIVE: The aim of this work was to compare the therapeutic value of ablative CO2 laser versus intradermal heparin sodium in xanthelasma. METHODS: This study was piloted on 30 xanthelasma patients, whose lesions were randomly categorized into two groups...

BACKGROUND: Photopatch testing represents the gold standard for the diagnosis of photoallergic contact dermatitis (PACD). We aimed to identify common photoallergens in our tertiary dermatological referral centre from 2012 to 2021, to compare this to the preceding period studied, and data from other communities. METHODS: We conducted a retrospective review of all 90 patients who underwent photopatch testing at the National Skin Centre, Singapore, between 2012 and 2021...

BACKGROUND/PURPOSE: Ultraviolet (UV) radiation has both harmful and beneficial effects on human skin and health. It causes skin damage, aging, and cancer; however, it is also a primary source of vitamin D. Additionally, UV radiation can impact energy metabolism and has protective effects on several cardiovascular and metabolic disorders in mice and humans. However, the mechanisms of UV protection against these diseases have not been clearly identified. METHODS: This review summarizes the systemic effects of UV radiation on hypertension and several metabolic diseases such as obesity, diabetes, and nonalcoholic fatty liver disease (NAFLD) in mice, and we also consider the mechanisms of action of the related regulators nitric oxide (NO) and vitamin D...

Sunless tanning products have risen in popularity as the desire for a tanned appearance continues alongside growing concerns about the deleterious effects of ultraviolet radiation exposure from the sun. Dihydroxyacetone (DHA) is a simple carbohydrate found nearly universally in sunless tanning products that serves to impart color to the skin. The Food and Drug Administration (FDA), which regulates sunless tanning products as cosmetics, allows DHA for external use while maintaining that its ingestion, inhalation, or contact with mucosal surfaces should be avoided...

BACKGROUND: The current ISO guidelines for minimal erythema dose (MED) determination require assessment of erythema area of UV-irradiated skin sites. However, this parameter has not been adequately quantified in daily practice. The aims of this study were to investigate the dose response on the unprotected skin sites by quantifying the erythema area and intensity and to show the potential for improving the precision and consistency of MEDu determination by developing predictive models...
