Guidelines to In Vitro Skin Absorption Studies
Pre-recorded Course
AN ON-DEMAND ONLINE TRAINING FORMAT
Who Should Attend
Skin absorption studies are part of various international regulatory requirements for safety assessment of exposure to
chemicals. For topically applied formulations, when the skin is the target of action, assessment of penetration can allow
for better product design. In vitro skin absorption studies were shown as a reliable way to evaluate penetration of
compounds into and through the skin.
The course will be beneficial to professionals in the pharmaceutical and cosmetic industries, especially those who are
involved in the following areas:-
Skin research and development
- Formulation chemistry
- Toxicology and regulatory affairs
- Technical sales and marketing
Description
This 90-minute course will explain the importance of evaluating skin absorption of compounds from topically applied formulations for safety assessment, mechanistic studies and prior to conducting clinical studies.
