Embodiments of the present invention disclose a method and system for managing pre- and in-sun exposure of skin. The method comprises during pre-sun exposure phase, inputting a location information of a user, and other contextual ambient information therefor, thereby facilitating determination of the UV level thereof, determining a baseline information in connection with the skin in a part of the day from at least one of midnight and dawn to noon, scanning at least one most predictably susceptible zone of one or more zones of the skin predictably susceptible to sun exposure, determining the Sun Protection Factor (SPF) level for a sunscreen for use by the user based on one or more quantifiable qualitative and quantitative parameters therefor, recommending the determined SPF level for the sunscreen for use by the user thereby facilitating search, identification and selection of one or more sunscreen products, solutions and regimens by the user, during in-sun exposure phase, at least one of determining whether or not the UV index of the location is confined in at least one of one or more predetermined ranges and reminding the user to scan the skin at one or more predetermined intervals depending upon the confinement of the determined UV index or level in at least one of the one or more predetermined ranges.

The disclosure relates to sunscreen compositions having a synergistic combination of ultraviolet light (UV) filtering agents that provide a high sun protection factor (SPF). Compositions according to the disclosure have high SPF values without requiring high overall amounts of UV filtering agents. Furthermore, the disclosure relates to methods of using the described compositions for protecting keratinous substances such as skin and hair from UV radiation.

Topcially applicable photoprotective compositions having improved sun protection factor, cosmetic properties and/or stability contain: (a) at least one 1,3,5-triazine UV-screening agent, (b) at least one mixture including: (i) at least one arylalkyl benzoate compound, and (ii) at least one oil containing in its structure at least one amide unit.

The present invention includes a process of preparing an advanced cosmetic product by combining a high internal phase ratio (HIPR) emollient-in-water emulsion with a partial cosmetic formulation that typically contains water, a coloring agent, a fragrance, a rheology modifier, or a pH adjuster, or a combination thereof. The present invention also includes compositions directed to two particular subclasses of HIPR emollient-in-water emulsions, namely an HIPR silicone elastomer-in-water emulsion and an HIPR sunscreen-in-water emulsion and water-diluted dispersions thereof. The use of an HIPR emulsion of a cosmetic emollient provides a simple and flexible method of formulating the cosmetic product, due in part to the long shelf-stability of the HIPR emulsion (greater than 1 year), and the low quantity of water in the emulsion (typically less than 20% by volume based on the volume of emollient and water). The HIPR sunscreen-in-water emulsion can be formulated into an advanced cosmetic product with an improved sun protection factor (SPF) and critical wavelength.
