Consumers expect skincare products to be suitable for their intended use, making safety an important consideration for cosmetic brands. Skin safety testing can evaluate how a formulation behaves when applied to the skin and may help identify potential irritation concerns. A patch test skin evaluation is one approach used in cosmetic testing to assess topical formulations. Dermasist Innovation Lab combines formulation development with stability testing, validation support, and testing capabilities as part of its personal care innovation process.
