Most pre workout supplements contain Beta-alanine. It is is known to cause paraesthesia in some people, especially when taking beta-alanine after a period of time not doing so. Paraesthesia is a skin-tingling sensation, that some people describe as a feeling of insects crawling on them. It is common to feel this in the face or hands. This sensation is not harmful, and some people enjoy it, finding it switches them on for the workout ahead.
