Publication date: Available online 7 November 2018Source: Actas Dermo-Sifiliográficas (English Edition)Author(s): A. Alegre-Sánchez, N. Jiménez-Gómez, P. BoixedaAbstractAbsorption of topical products through the epidermis is limited by the skin's barrier function. Numerous techniques and agents such as microneedling, dermabrasion, radiofrequency, and lasers have been used to increase penetration within an approach known as transdermal drug delivery. One of these techniques is laser-assisted drug delivery (LADD), which often uses ablative fractional lasers (CO2 or erbium:YAG lasers) because of their capacity to produce microscopic ablated channels. The parameters in LADD need to be adjusted to the patient, the skin condition and its location, and the drug. LADD has been used with various topical products, such as corticosteroids, photosensitizers, and immunotherapy agents (imiquimod or 5-fluorouracil) to treat numerous conditions, including scars, nonmelanoma skin cancer, and photodamage. LADD is a promising technique that enhances the absorption of topical molecules while adding the synergic effect of the laser.ResumenLa absorción de productos tópicos a través de la epidermis está limitada por la función de barrera cutánea.
