Brief Summary

The use of topical over-the-counter (OTC) products with a warming or cooling effect is widespread in the fields of sport, physiotherapy and in private households. Advertisements for such products promise pain relief when suffering from musculoskeletal disorders such as muscle tension, rheumatism or acute injuries, e.g. sprains. In literature, there are only little information about the efficacy and the physiological mechanisms of topical warming or cooling products. Therefore, the aim of this study is to investigate the local skin characteristics during and after an application of a topical product with a warming or cooling effect.
