Using proper methods, it is possible to screen materials for potential antiaging effects; in turn, these materials can be incorporated into cosmetic or personal care products. To properly screen antiaging materials, all that is required is a basic understanding of the aging process.

The authors describe a model to visualize the appearance of cyclobutane-pyrimidine dimers in the nuclei of normal human keratinocytes after UV irradiation. These dimers are one of the principal agents in DNA damage. The model can be used to assess the effect of a cosmetic ingredient on the formation of direct UV-induced lesions to DNA.

Texture analysis provides quantitative information about a material’s response when deformed by a controlled force. Examples illustrate the use of a texture analyzer to evaluate shampoo extrusion, hair spray film toughness, hair spray tackiness, styling wax hardness and aerosol canister deployment.

Several signs of skin aging have been attributed to the presence of free radicals. This paper discusses the application of two-photon fluorescence microscopy to determine the effects of sample formulations on the number of reactive oxygen species (ROS) formed in skin models.

To monitor or anticipate what can happen in the creation of a cosmetic product when components are combined and as time passes is no trivial task especially when compounded with the psychophysical needs for the product to fit a specific concept and to spread, feel, pour and appear elegant.

Described here was an in vivo model to determine antioxidative capacity of a topical skin care emulsion versus the emulsion’s vehicle on human skin that was exposed to UVR. Results suggest the test emulsion and its vehicle control inhibited the induction of erythema and reduced inflammation caused by the UV exposure.
