Disclosed is a smart lighting system for applying light to teeth in the context of tooth whitening. This particularly concerns teeth that have been provided with a light-curable whitening varnish. The system comprises a light-generating unit, a light-patterning unit, a mouth imaging unit, a mouth image sensing unit, and an image processing and control unit, and is adapted so as to allow the image processing and control unit to adjust the light-patterning unit on the basis of information obtained from the mouth image sensing unit. By doing so, prior to allowing the light-generating unit to emit light, it can be ensured that light emitted to assist tooth whitening, does not affect soft tissue.

The invention provides compositions of matter, methods and treatment means for improving cosmetic appearance of skin and restoring aged or damaged skin to a healthy appearance. One embodiment, the invention teaches administration of autologous adipose derived mesenchymal stem cells that have been cultured under “activating conditions”. In one specific embodiment activation is performed prior to administration of cells into patient's skin. In another embodiment adipose derived cells are administered systemically, with localization of stem cells to skin by administration of a localizing agent, said localizing agent comprising either a peptide; a protein; or a photoceutical.

A cap to be placed on a head of a device for treating the skin of a user includes an inner part to be removably attached to the head of the device, an outer part to be placed against the skin of the user and an interior disposed between the inner and outer parts. A product is disposed in the interior for application to the skin of the user and a covering, such as a membrane which is disposed on the outer part or a sterilized pack, is removable before use. An assembly having the device and the cap is also provided.

The invention relates to a process for dyeing and/or lightening keratin fibers using i) particular dye(s) and/or pigment(s), ii) photoactive compound(s) and iii) light source(s); a cosmetic composition comprising the ingredients i) and ii); the use of ii) for improving the fastness and/or dyeing and/or lightening of keratin materials in the presence of the ingredients i) and iii) of light source(s), and a multi-compartment device comprising i), ii) and iii). The implementation process and the use i) of particular dye(s) and/or pigment(s) combined with ii) the photoactive compounds and iii) with a light source make it possible especially to obtain lasting coloration on keratin fibers without the use of a reducing agent, and without odor.

Methods of forming cross-linked polysaccharides are disclosed in which one or more polysaccharides are dissolved in solution, gelled, modified to have a desired concentration, and subsequently irradiated. The irradiation of the gel crosslinks the polysaccharide(s) present. The disclosed techniques may be applied to various polysaccharides, including but not limited to agarose and/or hyaluronic acid.

Disclosed is a two-agent type hair coloring agent prepared by mixing a first agent and a second agent, wherein the first agent contains a dye component containing a basic dye as a main component, and an alkaline agent, the second agent contains a hydrogen peroxide solution as a main component thereof, and at least one of the first agent and the second agent further contains metal nanoparticles.

Proposed is a laser enhancer composition for improving melasma, wrinkles, skin tightening, pores, and acne by removing dead skin cells on an epidermal layer of the skin. The laser enhancer composition is used in a form applied to the epidermal layer during the treatment. The laser enhancer composition includes: either one or both of a peeling material and a heat conducting material that are configured not to be vaporized by a laser so that fumes are not generated; a viscous material configured to mix the peeling material 11a and the heat conducting material due to viscosity thereof; a volatile alcohol; and purified distilled water.

A cosmetic composition for sculpting nails, a method for sculpting nails which comprises the application of the cosmetic composition, and a brush-in bottle for applying the cosmetic composition are disclosed.

The present disclosure provides topical biophotonic materials and methods useful in phototherapy. In particular, the topical biophotonic materials of the present disclosure include a cohesive matrix, and at least one chromophore which can absorb and emit light from within the topical biophotonic material, wherein the topical biophotonic material is elastic. The topical biophotonic materials and the methods of the present disclosure are useful for promoting wound healing and skin rejuvenation, as well as treating acne and various other skin disorders.

The present invention relates to a composition for improving or promoting hair growth, which contains, as an active ingredient, a photosensitizer-peptide conjugate, and to a method for screening for the hair growth promoter using the active ingredients. ALA, which is the photosensitizer of the present invention, is preferably activated by LED radiation, and more preferably activated by radiation having a long wavelength of 650 to 675 nm. The peptide of the present invention is a peptide in which 3 to 7 amino acid residues are incorporated (most preferably, glycine-histidine-lysine), and may cooperate with the photosensitizer to enable very superior hair growth improving or promoting effects using light radiation. Further, the composition of the present invention may exhibit further superior effects when natural extracts (for example, Cimicifuga heracleifolia extracts, Scutellaria baicalensis extracts or Codonopsis lanceolata extracts) are added. Thus, the composition of the present invention can be significantly advantageously applied to drugs, quasi-drugs, and cosmetics.
