The present invention provides a method for treating a disease or condition in a subject, comprising administering to the subject's skin a composition comprising an effective amount of exosomes, wherein the composition is administered with a microneedle delivery device.

Methods for promoting hair growth, and needling devices for use with such methods, are provided. Certain of the methods include disruption of the skin with a powered needling device, followed by an administration of a hair growth-promoting agent.

Disclosed herein are drug delivery devices that can temporally and spatially deliver biologically active agents. An example drug delivery device includes a microneedle array comprising a plurality of microneedles on a surface of a substrate, each microneedle comprising a core comprising a hydrogel and a layer on a surface of the core. Also disclosed are methods of using the drug delivery device, and methods of making the microneedle array that includes a loading device.

A hair growth applicator for promoting the growth of hair follicles by applying hair growth liquid, comprising a handle having an internal chamber for containing said hair growth liquid, said handle having a channel running from said chamber to a distal end of said handle, a tip disposed at said distal end of said handle with a plurality of needles disposed on said distal surface of said tip, said distal surface having an opening, wherein said chamber is in fluid connection with said opening on said distal surface of said tip

A method for delivering therapeutics includes infusing a hydrogel with cannabis; and contacting the hydrogel infused with cannabis into a human which causes the controlled timed releasing of the cannabis with hydrophobic molecules to permeate through a lipid pathway.

A device includes a cartridge to contain a CBD or CGB solution; a laser or heat source coupled to the cartridge to release the CBD or CBG solution; and a variable voltage power source coupled to the laser or heat source to adjust heating temperature on the cartridge.

Provided are conformable light delivery devices for increasing light penetration depth and related methods. The device may comprise a microarray of tissue penetrating members, each member having a distal end and a proximal end, wherein the tissue penetrating members are at least partially optically transparent to provide optical transmission through a surface that extends between the distal and proximal ends of each tissue penetrating member and a substrate that supports the tissue penetrating members, wherein the substrate is optionally a flexible substrate.

An applicator for an analyte monitoring device may include an actuatable housing having a body defining a cavity therein and having a distal opening and a side opening. A cuff and a shuttle are received within the cavity and are separately translatable relative to the housing body. A base may removable engage the housing body at the distal opening. The housing body, the cuff, the shuttle, and/or the base may be engaged with one another with one or more releasable coupling features. The base may be removed from an engagement with the housing body, causing the cuff and the shuttle to be aligned and positioned in a configuration in which the analyte monitoring device, held by the shuttle, is ready for insertion into the skin.

The embodiments relate to improved skin quality, health and appearance using a new delivery method and certain bioactive compositions and formulations. The system incorporates microneedle delivery technology with unique compositions and formulations. Such development allows for the pursuit of personalized medicine, or treatment delivery that can expand to remote controlled environment, immediate compounding and ultimate personalization with a state of the art longitudinal data predictive analytics. Certain formulations described herein are unique, combinatory and synergistic. Secured by high-tech proprietary system, there are unlimited potentials using AQT technology including but not limited to 3-D printing of a biodegradable micro chips that can be delivered via injection, AQT or any other possible route.

A method for treatment for rejuvenation of hair growth combines three phases including a first phase typically applied once a month of micro-needling the area to be treated and thereafter applying an effective amount of a therapeutic; a second phase of applying an electric current and thereafter applying an effective amount of a therapeutic; the first phase typically being applied monthly and a third phase of a mechanical massage; the second and third phases likely being applied twice per week.
