Abstract
As an alternative to traditional needle injections, a number of non-invasive administrations have recently surfaced. Among these, a transdermal drug delivery system (TDDS) is the most appealing due to its low rejection rate, exceptional ease of administration, and exceptional patient convenience and persistence. In addition to the pharmaceutical industry, TDDS may find use in the skin care sector, which includes cosmetics. This approach can avoid local drug concentration accumulation and nonspecific drug delivery to tissues that are not the drug's target because it primarily uses local administration. Nevertheless, the physicochemical characteristics of the skin result in a number of barriers and limitations in transdermal delivery, and a great deal of research has been done to address these issues. We outline the various TDDS method types that are currently available in this review, as well as critically discuss each method's unique benefits and drawbacks, characterization techniques, and potential. Advances in the study of these substitute techniques have demonstrated the high efficiency that TDDS possesses, which is anticipated to find use in a variety of domains.
