Abstract:
Beautiful lips are responsible for facial attractiveness and a youthful appearance. During aging process, lips become thinner and the red lips borders get poor defined. Downturn of the corners of the mouth suggests negative emotions. Lip surgery and underlying pathology may result in asymmetries and lip incontinence. Minor invasive procedures with hyaluronic acid fillers and botulinum toxin A are versatile tools to improve appearance of the lips, restore function and improve psycho-social well-being. In this review, we discuss anatomy, safety concerns, injections techniques as well as esthetic and medical indications.
