Abstract

The stratum corneum acts as a barrier that limits the penetration of substances through the skin. Transepidermal drug delivery has been developed to increase the penetration of drugs through the superficial layers of the skin. There are many reports about ablative fractional resurfacing creating vertical channels that assist the delivery of topically applied drugs into the skin. The use of nonablative lasers as well as microneedling technique has been reported with the same purpose. In this chapter we are going to discuss some techniques, mechanism of action, and indications.
