Recent developments in sunscreens based on chromophore compounds and nanoparticles
Summary
This review covers recent advances in sunscreen formulations using nanoparticles and light-absorbing compounds. Researchers found that nanoparticles like zinc oxide and titanium dioxide can effectively scatter and absorb UV radiation while remaining cosmetically appealing, and that encapsulating UV-absorbing compounds in nanoparticles can enhance protection. The study also highlights progress toward more photostable, broad-spectrum, and environmentally friendly sunscreen options.
Sunscreen formulations have undergone significant advancements in recent years, with a focus on improving UV radiation protection, photostability, and environmental sustainability. Chromophore compounds and nanoparticles have emerged as key components in these developments. This review highlights the latest research and innovations in chromophore compounds and nanoparticle-based sunscreens. It discusses the role of nanoparticles, such as zinc oxide and titanium dioxide, in scattering and absorbing UV radiation while remaining cosmetically acceptable. Chromophore compounds, encapsulated in nanoparticles, are explored for their potential to enhance UV protection by absorbing specific wavelengths of light. Additionally, advances in photo-stability, broad-spectrum protection, antioxidant inclusion, and biodegradability are discussed. The evolving landscape of sunscreen technology aims to provide more effective and environment-friendly solutions for safeguarding skin from the sun's harmful effects.
