Retinol (Vitamin A) and Its Derivatives: Synthesis and Applications

This paper systematically reviews the synthesis methods of retinol (Vitamin A) and its derivatives, along with their applications in skincare and pharmaceuticals. By examining traditional chemical synthesis pathways such as the Roche, BASF, and Rhone-Poulenc routes, as well as modern biological synthesis pathways, the paper highlights the advantages and limitations of each method, particularly in terms of improving synthesis efficiency, reducing production costs, and minimizing environmental impact. The paper also analyzes the application of retinol derivatives in skincare, including their roles in anti-aging, skin barrier repair, skin whitening, and even tone. Additionally, the paper discusses methods to enhance the stability and bioactivity of retinol. Future directions include further innovation in synthesis techniques, the development of new derivatives, and new pharmaceutical applications of retinol. The paper concludes that retinol and its derivatives hold great promise in the beauty and health sectors, though further research is needed to overcome current challenges and promote wider application.
