Recent research shows there are two distinct types of aging. Aging caused by the genes we inherit is called intrinsic aging. While aging caused by extrinsic factors such as exposure to the sun is whole other ball game.
Intrinsic Aging a.k.a. Internal Aging
Internal aging, referred to by many wise souls as the natural aging process, is a continuous process that normally begins in our mid-20s. Even though our gene pool determines how quickly we’ll show the first signs of aging it’s safe to say that as early as our mid-20s the skin’s collagen production slows down and elastin (the substance that enables skin to snap back into place) has a bit less spring. Our mid- 20s reveal that dead skin cells don’t shed as quickly and turnover of new skin cells may decrease slightly. While these changes usually begin in our 20s, the signs of intrinsic aging are typically not visible for several decades (thank God for small miracles).
What are the many signs of internal aging on our skin?
It may be a pointless exercise to state the obvious, but I’ll enumerate them anyways:
• Fine wrinkles
• Thin and transparent skin
• Loss of underlying fat, leading to hollowed cheeks and eye sockets as well as noticeable loss of firmness on the hands and neck
• Bones shrink away from the skin due to bone loss, which causes sagging skin
• Dry skin that may itch
• Inability to sweat sufficiently to cool the skin
What are the many signs of external aging on our skin?
Most premature aging is caused by sun exposure. Repetitive facial expressions, gravity, sleeping positions and smoking are also factors that should not be ignored.
This might sound like a broken record but without protection from the sun’s rays, a few minutes of exposure each day over the years can cause noticeable changes to the skin. Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles that disappear when stretched, loose skin, a blotchy complexion, actinic keratoses (thick wart-like, rough, reddish patches of skin) can all be directly traced to sun exposure. Obviously, skin cancer is the most extreme (and most regrettable) form of sun exposure.
