Provided is an adhesive gel nail which includes a base film, an adhesive layer on the base film, a printed layer on the adhesive layer, an UV gel coating layer on the printed layer, an LED gel coating layer on the UV gel coating layer, and a highpoint glossy-top coating layer on the LED gel coating layer, and the highpoint glossy-top coating layer is formed by applying and drying a glossy-top coating solution in which a monomer, an oligomer, a cellulose, and a long-wavelength initiator are mixed.

The present subject matter relates to light-activatable polymeric nanoparticles (NPs) for the transportation and release of an active substance, methods for obtain said particles and their uses. A light-activatable nanoparticle for the transportation and release of an active substance, comprising a polycation preferably a polimer polycation, a polyanion and a light-sensitive photochrome attached to the polycation or the polyanion, wherein said photochrome is hydrophobic and suitable to photo-cleave when activated by an irradiation source, generating a negative charge and releasing the active substance. Light-activatable. The disclosure subject matter shows that NPs are a highly efficient drug delivery system to primary leukemic cells based on opto-nanomedicine system. Therefore, the present disclosure is useful for remote control in the release of biomolecules with spatio-temporal resolution with applications in the areas of general therapeutic and regenerative medicine applications.

A curable composition comprising (a) an organopolysiloxane comprising a curable functional group; (b) a cross-linker comprising a silyl hydride group or a thiol group; (c) a reaction accelerator; (d) optionally an inhibitor; and (e) optionally other additives. The curable composition exhibits high refractive index and optical clarity. The curable composition can be used to prepare a cured material that exhibits high refractive index, optical clarity, crack resistance, and low moisture vapor permeability.

A multi-phase oral composition and electromagnetic radiation source for whitening teeth.

Disclosed herein is an artificial fingernail that magnetically affixes to the fingers of a user. The user first applies a clear magnetic nail polish to their fingers. When dry, the artificial fingernail, manufactured including magnetic polymers, affixes directly to the magnetic nail polish coating. In various embodiments, the magnetic polymers used in the artificial fingernail are configured to various contexts and preferences.

Naphthalimide compounds are used in tissue bonding and protein cross-linking applications. When activated by an activating agent, such as light in the 400-500 nm absorption range, the naphthalimide compounds form chemically-reactive species that cross-link proteins, bond connective tissues together, and bond tissues and other biomaterials together. A naphthalimide-labeled biomolecule, such as a naphthalimide-labeled chitosan, is also capable of bonding tissues without subsequent direct illumination of the contacted tissue area. The naphthalimide compounds may be used in tissue or arterial repair, stabilization of an expanded arterial wall after angioplasty, tethering pharmaceutical agents to tissue surfaces to provide local drug delivery, and for chemically bonding skin care products, sunscreens, and cosmetics to the skin.

The present disclosure provides cosmetic compositions and methods for using the cosmetic compositions. In particular, the cosmetic compositions of the present disclosure include one or more chromophore(s) in association with a dermatologically acceptable carrier. The cosmetic biophotonic compositions and the methods of the present disclosure are useful for skin rejuvenation and/or skin conditioning.

A multi-phase oral composition for delivering active agents.

The present invention provides compositions, methods and kits for treating skin, which combine administration of glucosamine hydrochloride and red light having a peak wavelength of about 600 nm to about 750 nm, near infrared light having a peak wavelength of about 750 nm to about 1000 nm, or both.

The method comprises the following steps: (a) forming a powder layer (19) comprising at least one cosmetic powder; (b) supplying a photoactivatable material on at least a first region of the layer (19); (c) illuminating at least the first region of the layer (19) to activate the photoactivatable material; (d) forming an additional powder layer (19) comprising at least one cosmetic powder; (e) supplying a photoactivatable material on at least a second region of the additional layer (19); (f) illuminating at least the second region of the additional layer (19) to activate the photoactivatable material; (g) repeating steps (d) to (f) until the three-dimensional object is formed.
The cosmetic composition comprised in the three-dimensional object or forming the three-dimensional object can be restored after the three-dimensional object is formed.
