Cosmetic actives, even those with proven efficacy, only perform optimally in cosmetic products when they are delivered in the correct spot of the skin and in the correct amount. The right spot can be quite variable depending on the active. Some actives work on the surface, others in the stratum corneum, and others may need to penetrate deeper into the living layers of the skin.
The type of cosmetic product and the specific formulation, therefore, play a fundament role in ensuring an efficacious delivery. In addition, cosmetic products are also expected to have good sensorial properties. The combination of both efficacy and pleasant properties increases the challenge.
This course offers both a comprehensive view of the fundamental aspects behind the effective delivery of actives (Day 1), as well as the practical aspects of selecting an appropriate product, and the specifics of the formulation process (Day2).
Who Should Attend
The course will be of immediate value to those involved in formulating cosmetic products containing actives. It will also be of general interest to anyone working in the cosmetics industry in a research or product development lab. Those working in marketing will also benefit from the concepts presented on Day 1.
