Research Summary: The role of cosmetic products is rapidly evolving in our society, with their use increasingly seen as an essential contribution to personal wellness. This suggests the necessity of a detailed elucidation of the use of nanoparticles (NPs) in cosmetics. The aim of the present work is to offer a critical and comprehensive review discussing the impact of exploiting nanomaterials in advanced cosmetic formulations, emphasizing the beneficial effects of their extensive use in next-generation products despite a persisting prejudice around the application of nanotechnology in cosmetics. The discussion here includes an interpretation of the data underlying generic information reported...

Research Summary: Skin health is an important aspect of aesthetics. Dermatologists and scientists continually strive to develop novel methods and materials to achieve healthy skin. Facial cosmetics help keep skin moisturized and remove sebum to maintain proper skin health. The use of suitable cosmetics according to one's facial skin type results in healthier skin. Among these cosmetics, facial masks are the most prevalent products utilized for skin rejuvenation.Facial masks are divided into four groups: (a) sheet masks; (b) peel‐off masks; (c) rinse‐off masks; and (d) hydrogels. Each type offers specific advantages for particular skin types based on the ingredients used....

Research Summary: The skin is constantly exposed to various environmental stresses, particularly the damage caused by pollution and ultraviolet (UV) radiation. As a consequence, the outer layer of the skin can be negatively impacted by the harmful influence of some of its surface components. The mechanisms involved in the degradation processes promoted by UV radiation are driven by the direct absorption of radiation via cellular chromophores, the formation of excited states, and the consequent chemical reactions. In addition, photosensitization mechanisms occur, in which UV light is absorbed by sensitizers that become excited, leading to the formation of reactive oxygen species...

Research Summary: The aging population and a desire to maintain a youthful appearance have propelled the recent surge in the U.S. cosmeceuticals market. The rapidly growing number of products claiming to diminish fine lines and wrinkles, decrease redness, smooth texture, and fade discoloration has led to much confusion and misinformation among dermatologists and consumers alike.Cosmeceuticals can be a useful adjunct to prescription medications and office procedures. Therefore, it is important for dermatologists to understand the science behind these products to better educate themselves and their patients.We present an update on the following categories of cosmeceuticals: antioxidants, growth factors, peptides, anti-inflammatories/botanicals,...
