Microneedling with Biologicals

Microneedling is a popular and cost-effective treatment with little down time. The application of topical agents to enhance outcomes is common practice. Microchannels created with nonthermal needling close at 4 hours to 6 hours due to fibrin plugs. Channels created with thermal needling or fractional laser stay open longer and enhance drug or biological uptake more due to the dermal sponge injury pattern that is created. Nonthermal microneedling devices may need Food and Drug Administration clearance, which also notes that dermaceuticals should be considered drugs in many cases.
