A dermal applicator device may include a housing having a retainer configured to hold and engage a spherical surface. A reservoir, containing a liquid, is contained within a shell that is at least partially spherical but at least has curved surfaces supporting rotation. The shell may be engaged within the retainer to permit relative rotation of the shell with respect to the housing. The liquid may be selected to have a freezing point below 0 C. and/or a specific latent heat of fusion higher than water. The shell may further include an outwardly protruding lug extending from its surface, and the housing may be configured to form an orbital chamber between an inner surface thereof and the shell when the shell is retained in the retainer. The protruding lug is constrained within the orbital chamber such that rotation of the shell relative to the housing is restricted.

The present invention provides a cosmetic device having a massage function by rolling a roller disposed to a main body part, a suction function with a suction unit, and a stimulation function by outputting a stimulation signal with the roller. Since these functions can be combined and performed in use, the cosmetic device can synergistically exert an effect of dissolving cellulite of user's skin and releasing fascia. While the cosmetic device is multi-functional, the main body part has a compact structure with the suction unit inside and the roller on a bottom surface that are arranged and integrated, as well as an insertion part formed by a space that can be inserted with a user's hand, and a placement part that can be placed with a palm of the user's hand inserted into the insertion part, allowing the cosmetic device to be easily used by holding with one hand.

There is provided a phototherapy apparatus, in which the therapeutic light is delivered through one or more massage components. The massage component provides mechanical massage to the subject biological tissue and modifies the properties of the subject tissue in thickness, density, etc. to facilitate the absorption of the therapeutic light and enhance the effect of the phototherapy procedure. The light source of the phototherapy apparatus is actively cooled by a synthetic jet cooler.

A multilayer hollow massage auxiliary tool and a manufacturing method thereof are disclosed. The manufacturing method includes steps of: disposing a first plastic material in a mold cavity; allowing the first plastic material to be melted and expanded for forming as a first gel layer; allowing a second plastic material to be disposed in the mold cavity; allowing the second plastic material to be disposed in the first gel layer and melted and expanded for forming as a second gel layer; allowing the first gel layer and the second gel layer to be gelled as one piece; and allowing the first gel layer to be solidified to form as an outer body and allowing the second gel layer to be solidified to form as an inner body.

A skincare tool is configured with a base member that includes a magnetic coupling device. The magnetic coupling device allows one tool to be coupled to another tool, and for a plurality of tools to be coupled together. A tool member is disposed at the opposite end of the base member. The base member, which can also function as a grip or handle for the skincare tool, has a unique and ornamental design. The base member enables multiple skincare tools to be magnetically coupled together while at the same time providing improved handling and hygiene of skin care tools.

A barbell massage roller includes a roller core having a roller core cavity defined therein. A longitudinal center axis of the barbell massage roller extends through a center of the roller core cavity. The barbell massage roller further includes a roller body having a roller body cavity defined therein. The roller body is disposed on the roller core. The roller body further includes a plurality of helical clusters, each including a plurality of helical protrusions. Each of the plurality of helical protrusions define at least one curved massage surface area. At least the roller core cavity is shaped and sized such that the barbell massage roller is capable of being installed onto a sleeve of a barbell, thereby permitting a user to administer self-massage when the barbell massage roller is installed onto the sleeve of the barbell. At least one method of using a barbell massage roller is disclosed.

A massage device provides a gentle massage and myofascial release. The massage device comprises a first roller set and a second roller set that are configured so that the first roller set makes a first contact that displaces the tissue being massaged and, prior to the tissue returning to its natural state, the second roller makes a second contact with the tissue being massaged, thus providing a deeper, extended massage to the tissue. Also disclosed is an ergonomic handle for a massage device that also functions as a trigger point release tool.

A therapeutic, fitness, and sports enhancement device which includes a cylindrically shaped body having a predetermined density and predetermined diameter, the body including a plurality of projections of a predetermined shape. One or more of the predetermined density and the predetermined diameter in combination with the predetermined shape of the projections optimize mobilization of soft tissue structures of the human body.
