will using a sunbed or going on holiday reduce the effects of botox?
Prior to injection, the botox bottle needs to be stored at a certain temperature to maintain its safety and effectiveness. Once injected, Botox is already starting to work within ~30 minutes and temperature changes should not affect its safety or efficacy. That being said, tanning and extremes of heat are not good for your health and should be avoided regardless of Botox injections.
