People who sleep on their side or stomach exert compression, shear and stress force factors on their faces that result in distortion and, ultimately, wrinkles, according to a study published in the Aesthetic Surgery Journal. Fillers and neuromodulators are ineffective or short-lived in sleep-induced wrinkles, says study leader and plastic surgeon Goesel Anson, but radiofrequency and ultrasound devices or microneedling might be options, according to American Society for Aesthetic Plastic Surgery President Daniel Mills.

Depression affects over 120 million people globally, making it one of the leading causes of disability in the world. Although there are various effective treatments, therapeutic response remains unsatisfactory and depression can develop as a chronic condition in a considerable proportion of patients. Negative emotions, such as anger, fear, and sadness are prevalent in depression and also are associated with hyperactivity of the corrugator and procerus muscles in the glabellar region of the face. In 1872, Charles Darwin recognised these features as a very specific expression of sadness and attributed them to the activity of so-called ‘grief muscles’ in the glabellar region. He also formulated a new theory called the ‘facial feedback hypothesis’, which implied a mutual interaction between emotions and facial muscle activity. More recently, Larsen et al. have shown experimental evidence that voluntary contraction of facial muscles can channel emotions, which are conversely expressed by activation of these muscles.
