"Impact of High Coverage Make-up Coverage against Visible Light Exposure"

Authors: Hawasatu Dumbuya, PhD & Janet Wangari-Talbot, PhD

The following is a selected scientific poster abstract from the 2019 Skin of Color Update.

Historically, photo-protection studies have focused on UVB (280-320 nm) and UVA (320-400 nm) protection. However, it is now evident that visible light (400-700 nm) causes skin darkening and contribute to worsening of dyschromia, particularly in individuals with Fitzpatrick phototype III and higher.

Currently, few sunscreens provide protection against visible light. Due to their capabilities in absorbing and reflecting visible light, topical products containing pigments and/or metal oxides (i.e. iron oxide, zinc oxide, and titanium dioxide), can provide additional protection against harmful effects of that spectrum.

Here, we demonstrate that lightly or darkly tinted high coverage pigmented foundation containing iron oxides or a combination of iron oxide and titanium dioxide significantly protected against visible light-induced pigmentation when compared to a mineral SPF50+ sunscreen in Fitzpatrick IV individuals when assessed by visual grading and by chromameter.

Our results show the benefits of high coverage pigmented foundation, containing different concentrations of iron oxide and titanium dioxide, in offering visible light photoprotection. Depending on the metal oxides concentrations, these formulations have the potential to extend protection beyond UV for multiple skin phototypes.

The Experts’ Forum for Multicultural Dermatology

The US population is growing and evolving and the clinical profile of the average patient presenting to the dermatologist is changing. One in three Americans self-identify as member of a non-caucasian racial or ethnic group. Data shows as of 2020, individuals of non-Caucasian, multi-racial descent will comprise more than 50% of the population.

"Safety, Tolerability, and Efficacy of Repeat-Dose Injections of IncobotulinumtoxinA in the Treatment of Upper Facial Lines: Results from a Prospective, Open-Label, Phase III Study"

IncobotulinumtoxinA (Xeomin/Xeomeen/Bocouture/XEOMIN Cosmetic; botulinum toxin type A free from complexing proteins [150 kDa]; Merz Pharmaceuticals GmbH) is indicated worldwide for the correction of glabellar frown lines (GFL) and in Europe additionally for lateral periorbital lines (LPL; crow’s feet) and upper facial lines (UFL; ie, simultaneous treatment of GFL, LPL, and horizontal forehead lines [HFL]).1

The efficacy of incobotulinumtoxinA in the treatment of multiple or singular facial areas has been extensively demonstrated.2-10 With the recent surge in interest for a more holistic approach, consisting of combined treatment of GFL, HFL, and LPL in a single treatment session, there is a need for demonstrating safety and efficacy for such procedures.

This study provides strong evidence for the safety and tolerability of repeat-dose treatments with incobotulinumtoxinA in UFL (GFL, 20 U; HFL, 10-20 U; LPL, 24 U). A stable safety profile was demonstrated during prolonged administration and a noteworthy trend to better tolerability with continued use of incobotulinumtoxinA was established
