Facial rejuvenation Facial rejuvenation Facial rejuvenation is a cosmetic treatment (or series of cosmetic treatments), which aims to restore a youthful appearance to the human face. Facial rejuvenation can be achieved through either surgical and/or non-surgical options. Procedures can vary in invasiveness and depth of treatment. Surgical procedures can restore facial symmetry through targeted procedures and facial restructuring and skin alterations. Non-surgical procedures can target specific depths of facial structures and treat localized facial concerns such as wrinkles, skin laxity, hyperpigmentation and scars. Surgical (invasive) facial rejuvenation procedures can include a brow lift (forehead lift), eye lift (blepharoplasty), facelift (rhytidectomy), chin lift
Facial symmetry associated with the symmetry of the face. Hormones such as testosterone and estrogen are believed to be associated with developmental processes and growth of facial features during puberty and as a result are hypothesized to be the cause for individual differences in the implications associated with facial symmetry. Facial bilateral symmetry is measured via fluctuating asymmetry of the face comparing random differences in facial features of the two sides of the face that develop and accumulate throughout one's lifetime as a result of stressors. Facial symmetry has been shown to have an effect of ratings of attractiveness in human faces.
