Abstract
Abstract: Aging is relentless process that affects all cells, tissues, organs & organisms, diminishing homeostasis and increasing organism vulnerability.
Aging at molecular levels results from increasing entropy that exceeds repair and turnover capacity - a process called ‘Molecular Fidelity’
Aging is a dynamic, biological process of tissue involution and evaluation.
Aging results from both extrinsic and intrinsic factors and may related to ethnic ,variation given innate difference in skin composition due to racial and ethnic background .
We reviewed publications through PubMed search and textbook chapters.
Aging is a multidimensional process including volumetric change, migration of fat pads, absorption of bone, changes in SMAS and extrinsic reflections of environmental factors on skin.
Whatever skin type, signs of aging maybe dark spots, loss of elasticity, loss of volume and rhytides.
Skin of colour has many characteristics that make its aging process unique.
Aging consists of changes of facial rheology eg Volume deflation, Jowl that appears with aging, has been thought in past to represent descent of that part of the jaw line, in reality entire jawline recedes superiorly to expose the jowl. Its volumetric deflation rather than a descent.
Asian skin manifest differently to aging than Caucasians. Increased concentration of melanin in skin of colour makes them more prone to depigmentation – on a positive note more compact dermis makes facial lines and wrinkle less visible.
We need to be aware of differences of biology of Asian skin and clinical approach to aesthetic management of Asian Skin.
Recognizing the unique characteristics of Asian skin allows physicians to optimize cosmetic results and ultimately to a successful rejuvenation of Asian Skin. Aesthetic doctors and Lasers practitioners must be aware of photo damage in Asians and understand the risk of post- inflammatory hyperpigmentation associated with various therapeutic modalities.
