Article Synopsis
- A study aimed to evaluate how consistent and accurate trained raters are when using two versions of the Vitiligo Area Scoring Index (T-VASI and F-VASI) to assess the severity of vitiligo in participants.
- Results showed that inter-rater reliability improved for facial assessments, while overall reliability for full-body assessments was consistently good, indicating the method is effective.
- Limitations included a small sample size and the lack of in-person evaluations, but the findings suggest the Vitiligo Area Scoring Index is a reliable tool for assessing vitiligo severity when used by trained individuals.

Background: Long wavelength ultraviolet-A1 in combination with visible light induces hyperpigmentation, particularly in dark-skin phototypes. This study evaluated the efficacy of four sunscreen formulations in protecting against VL + UVA1 (370-700 nm).
Methods: The test products (A-D) were applied to the back of 12 volunteers, then irradiated with 320 J/cm VL + UVA1 (3.
Visible light (VL, 400-700 nm) was previously regarded as nonsignificant with minimal to no photobiologic effects on the skin. Recent studies have demonstrated that in dark-skinned individuals (skin phototypes IV-VI), VL can induce more intense and longer lasting pigmentation compared to ultraviolet A1 (UVA1, 340-400 nm). Additionally, long wavelength UVA1 (370-400 nm) has been shown to potentiate these effects of VL.

Human skin is not only affected by ultraviolet radiation but also by visible light wavelengths emitted by sunlight, electronic devices, and light emitting diodes. Similar to the ultraviolet radiation, visible light has been implicated in photoaging. In this review, the effects of blue light, yellow light, red light, and broad visible light are discussed in relation with photoaging.

Standardized extract of the Polypodium leucotomos fern, PLE, possesses anti-inflammatory and antioxidant properties, and has been shown to potentially mitigate photoaging through various mechanisms. This comprehensive review presents the data available on the effects of P.

The use of natural ingredients for nonscarring hair loss has gained popularity among patients, but has not been previously studied for CCCA. We sought to review clinical studies evaluating the use of natural ingredients in the treatment of CCCA.

Methods: We conducted a qualitative study with pregnant and postpartum patients recruited from 2 prenatal care clinics at an urban, academic hospital in the United States.
