10 Standard dermatological tests while effective in many respects do not always provide the best path forward in characterizing the activity of your molecule or product. Given our past experience in working to develop and commercialize cosmetics, extracts, pharmaceuticals and nutraceuticals, we possess innovative capabilities in protocol design, assay development and claim support testing. With the support of our knowledgeable project management team, we can demonstrate the activity of your molecule or product and tailor the appropriate assay systems to produce exciting scientific data to deliver your study objectives and support your product s brand goals. Contact us today to select the tests that best fit the vision and criteria of your compound. Together, we will develop the appropriate dermatology assay project that will provide you with robust scientific reasoning, results and claims for your product.

11 Profile 001 Multiple Several Multiple Several Assay specific To identify and/or characterize molecules that have beneficial effects on skin cells, Signum Dermalogix has developed a broad based screen to test your compound, ingredient or extract. This initial screening strategy is employed to assess a small molecule s activity and comparing it to several standard reference compounds that are broad acting in their activities, since the dermal inflammatory response is realized through interplay between a numbers of different cell types: keratinocytes, endothelial cells, fibroblasts and various leukocytes. Initial profiling efforts test the effects of compounds in several commonly accepted cellular models of inflammation utilizing a number of these cell types. In addition to measuring inhibitory effects of various markers of inflammation, testing for antimicrobial activity and evaluating effects on keratinocyte differentiation is also performed. Altogether this initial characterization will determine your compound of interest s activities over a broad number of cellular systems and molecular endpoints. This type of profiling is especially valuable in identifying potentially new or additional claims for your molecule that may have previously been missed or during early stage discovery. This screening program will*: Identify the skin and immune cell types affected by the compound Discover the specific molecular processes that are modulated by the compound Determine if the small molecule has anti bacterial activity versus skin flora Determine activity of each molecule in regulating cellular processes & microbial growth Discover the viability of several skin & immune cell types in the presence of the compound Determine if the compound has anti oxidant properties *Signum Dermalogix can customize screening to your own specification and target(s) of interest. Assays may be swapped if specific tests listed in our standard assay system are of greater interest for studying your molecule. 10

12 Skin layer SPEN 001 Pig Skin (ex vivo) Basal levels Franz Cell Vehicle Once a compound or product is found to be effective in vitro, the next steps in development for skin care call for the compound to be formulated to assess it dermal penetration profile, stability and further safety testing. In addition to custom assay development and characterizing the activity and safety profile of your compound or product, Signum Dermalogix provides analytical and testing services including: Analytical support (HPLC, LC MS, NMR) Method development Stability assessment Radioisotope labeling Franz cell dermal penetration studies Pre formulation assessment In vivo safety assessment We maintain an NRC license to use radioisotopes and have an Institutional Animal Care and Use Committee (IACUC) in place for SOP approval and compliance with animal safety testing regulations. Early development and precise strategy can reduce costs and accelerate timelines.
