An oil base skin care composition including squalane and a method for treating skin are disclosed. The method includes the step of individually displaying a plurality of visual skin guides to a consumer. Each of the visual skin guides includes a plurality of visual representations of a categorical skin condition. Each of the visual representations correspond to a severity score for the categorical skin condition on the visual skin guide. The method further includes correlating the severity score for each of the categorical skin conditions for each of the visual skin guides to the consumer's current skin condition. At least two target skin conditions from the plurality of categorical skin conditions are determined in response to the severity scores for each of the categorical skin conditions. At least one booster containing at least one active ingredient is correlated for treating each target skin condition.

An apparatus for non-invasively measuring bio-information is provided. The apparatus for estimating bio-information may include a pulse wave sensor including a plurality of channels, and configured to measure pulse wave signals at a plurality of points of an object; and a processor configured to generate oscillograms corresponding to the plurality of channels based on the pulse wave signals measured by the plurality of channels; determine a channel, from among the plurality of channels, for estimating the bio-information based on the oscillograms; and estimate the bio-information based on an oscillogram of the channel.

Service can be offered free of charge and the cost of a skin condition measuring device can be reduced by effectively using data on the occasion of obtaining an analysis result by transmitting measurement data by the skin condition measuring device to a server of a company providing a service of analyzing the measurement data. When a request is made from a contractor client to acquire data registered in a measurement data database, authentication is executed based on a contractor ID input from the contractor client. Additionally, when the measurement data database is searched from a contractor database based on the contractor ID, a search level and an access level are obtained. The contractor client is permitted to search the measurement data database within a range of the search level and the access level.

A system for recommending ultraviolet protection for a subject's skin includes an interrogation device, an analysis device, and an output device. The interrogation device has an ultraviolet sensitive module configured to generate interrogation data based on sensed electromagnetic energy reflected by the subject's skin in response to irradiation of the subject's skin by an ultraviolet electromagnetic energy source. The analysis device is configured to receive the interrogation data from the interrogation device and generate an ultraviolet analysis, which includes a recommendation for further ultraviolet protection of the subject's skin, based at least in part on the interrogation data. The output device receives the ultraviolet analysis and outputs the recommendation for further ultraviolet protection of the subject's skin.

The present invention relates to a method for determining the relief of the skin surface of a subject, and hence the degree of maturation of the said skin surface. Methods for identifying active agents, raw materials and formulation are also provided.

A method of processing optical coherence tomography (OCT) scans through a subject's skin, the method comprising: receiving at least a plurality of OCT scans through the subject's skin (7), each scan representing an OCT signal in a slice through the subject's skin (7), with the plurality of OCT scans being spaced apart such that the OCT scans represent the OCT signal through a volume through the subject's skin; processing each OCT scan using a processor so as to so as to detect at least one three dimensional structure in the skin; classifying, using a processor, the structure as belonging to a class of a plurality of classes of structures; and outputting at least one of the structure and the class.

Provided is a contactless internal measurement device including an electromagnetic wave irradiation unit that irradiates an electromagnetic wave to a measurement subject, and an electromagnetic wave receiver that detects the electromagnetic wave reflected by the measurement subject. The electromagnetic wave irradiation unit is disposed to reduce a polarization component of the electromagnetic wave detected by the electromagnetic wave receiver, the polarization component being the same as a polarization component of the electromagnetic wave irradiated by the electromagnetic wave irradiation unit.

A system and method for providing personalized cosmetic information objectively and scientifically present personalized cosmetics suitable for an individual's skin type by a comparative analysis between genetic skin test result data, from which an individual's skin condition can be scientifically detected, and data obtained by a phenomenological self-skin examination and a skin condition measurement instrument.
