and forums . It is always advisable to consider the source of the information you ’ re exposed to . At iS Clinical , we prioritize being a trusted industry resource and leader by providing the latest information in science and innovation . Those with careers in the skincare field are often educating others and debunking many skin myths and falsehoods . Vitamin A is one of the most misunderstood and questioned ingredients in skincare products . Each week , we field inquiries either seeking out Vitamin A products or expressing fear about using them . It is imperative that we accurately speak to the function and purpose of Vitamin A so that everyone can benefit from it .
Vitamin A doubles as a fat-soluble vitamin and an antioxidant . It is widely known as a skin normalizing vitamin , making it critical in achieving and maintaining homeostasis . For example , in acneic skin , Vitamin A may slow down cell proliferation since this skin disease often causes an increase in this process . Conversely , in aging skin , Vitamin A will speed up cell proliferation since normal exfoliation is declining . Historically , Vitamin A was termed “ the anti-infective vitamin ” due to its importance in normalizing the immune system .
It is an essential vitamin that our skin and body rely on to complete its most necessary tasks . Vitamin A and all its forms are chemically categorized as “ retinoids .” This is an official umbrella term used in science , medicine , and skincare to indicate use of the vitamin or to indicate that the vitamin family is being referenced . In strict chemical language , however , the term “ retinoid ” refers to a derivative of the parent compound of Vitamin A ( retinol ).
Single solutions are rare for those suffering from problematic skin , and combination measures are usually necessary .
