Dermatological Implications of Facial Bone Aging

Wrinkles and fine lines are the most evident manifestation of facial aging. It is not just the skin structural and facial muscles change that contribute to the formation of wrinkle such as loss of elasticity and volume. Changes in bone … Continue reading

Structural, Histological And Clinical Changes In Chronologic Aged Skin And Photoaged Skin

Many of facial skin aging changes are not the inevitable result of chronologic aging, but with the accumulation of chronic environmental factors. The structural (molecular, cellular), histological changes and the clinical signs associated with intrinsic (chronological aging) and photoaging are … Continue reading

Facial Wrinkle Lines And Anatomy of Facial Muscles

The complex group of facial muscles are related to the facial lines that are caused by the contraction of and/or the repeated movement of facial muscles. Combined with the aging factors which result in the loss of skin elasticity and … Continue reading
