Aging of the skin of the neck is a multi-faceted process stemming from both intrinsic and extrinsic factors. (A) Under common conditions without ligands, the activity of receptor tyrosine kinases (RTKs) on the cell surface is inhibited by receptor protein tyrosine phosphatases (RPTPs), which dephosphorylate RTKs and keep low levels of signaling, producing a normal amount of collagen and matrix metalloproteinases (MMPs). the extrinsic aging process, should be controlled by living a healthy lifestyle! DNA damage can be repaired in lesser species through removing the lesion by photolyase enzyme, but higher mammalian and human cells dont have this enzyme. On the other hand, extrinsic skin aging happens when external factors (which can be avoided) affect our body's natural aging process. I have also suspected that maintaining a stressful life played a role as well. 2014 Sep;13(3):188-94. doi: 10.1111/jocd.12097. Intrinsic aging is also termed true aging which is an inevitable change attributable to the passage of time alone and is manifested primarily by physiologic alterations with subtle but undoubtedly important consequences for both healthy and diseased skin and is largely genetically determined [ 1 ]. Slower production of stem cells, estrogen loss, reduced collagen and elastin, and deteriorating facial tissues are all part of intrinsic aging. Under common conditions without ligands, the activity of receptor tyrosine kinases (RTKs) on the cell surface is inhibited by receptor protein tyrosine phosphatases (RPTPs), which dephosphorylate RTKs (Fig. Kueper T, Grune T, Prahl S, Lenz H, Welge V, Biernoth T, Vogt Y, Muhr GM, Gaemlich A, Jung T, et al.
