Answers:
Normal healthy skin has a nice epidermis near a smooth cornified, or outer, layer that acts as a apt barrier to water and environmental injury. Skin color and tone is even and unblemished. Components such as collagen (which provides skin firmness), elastin (which supplies skin elasticity and rebound) and glycosaminoglycans or GAGs (which save the skin hydrated) are all abundant. It is interesting to document that under a microscope a biopsy of a wrinkle exhibits no telltale signs that reveal it to be a wrinkle. So what causes the skin to look wrinkled? It is probably a multi-factorial process of intrinsic aging and extrinsic aging.
Intrinsic aging is the crude aging process that takes place over the years regardless of outside influences. After the age of 20, a person produces nearly 1 percent less collagen in the skin respectively year. As a result, the skin becomes thinner and more fragile with age. There is also diminished functioning of the sweat and grease glands, less elastin production, and less GAG formation. Wrinkle formation as a result of intrinsic aging is inevitable, but it will other be slight.
Extrinsic aging occurs in complement to intrinsic aging as a result of sun and environmental damage (tobacco use and exposure to pollution, for example). Extrinsic aging shows up as thickening of the cornified deposit, precancerous changes such as lesions call actinic keratosis, skin cancer (including basal cell carcinoma, squamous cell carcinoma, lentigo maligna melanoma), freckle and sun spot formation, and exaggerated loss of collagen, elastin, and GAGs. Alone or in concert, these processes give the skin the appearance of roughness, crooked tone, brown patches, thin skin and low wrinkles.
Prevention is key to minimizing wrinkles. The most important point is to take care of your skin since all these changes start to whip place. Sun protection against both UVA and UVB rays is critical 365 days a year using an SPF of at least 35: I prefer zinc- or titanium-based products. After the age of 25 I recommend using Retin-A (a vitamin A derivative that uses the generic name tretinoin) as an antiaging cream. It is a prescription agent that have been used for more than 30 years with a nontoxic track record and excellent results. In the first two or three months patients may experience redness, crumbling and flaking, but should then noticed a mottled improvement. Over time tretinoin improves fine lines, the appearance of pores, precancerous change, and brown spots. If tretinoin treatment is not enough, then environment depth chemical peels and some non-invasive lasers can help build collagen and thus augment the skin's appearance..

Intrinsic aging is the pure aging process that takes place over the years regardless of outside influences. After the age of 20, a person produces something like 1 percent less collagen in the skin respectively year. As a result, the skin becomes thinner and more fragile with age. There is also diminished functioning of the sweat and grease glands, less elastin production, and less GAG formation. Wrinkle formation as a result of intrinsic aging is inevitable, but it will other be slight.
Extrinsic aging occurs in appendage to intrinsic aging as a result of sun and environmental damage (tobacco use and exposure to pollution, for example). Extrinsic aging shows up as thickening of the cornified level, precancerous changes such as lesions call actinic keratosis, skin cancer (including basal cell carcinoma, squamous cell carcinoma, lentigo maligna melanoma), freckle and sun spot formation, and exaggerated loss of collagen, elastin, and GAGs. Alone or in concert, these processes give the skin the appearance of roughness, potholed tone, brown patches, thin skin and gaping wrinkles.

It is a prescription agent that have been used for more than 30 years with a protected track record and excellent results. In the first two or three months patients may experience redness, blistering and flaking, but should then noticed a streaked improvement. Over time tretinoin improves fine lines, the appearance of pores, precancerous change, and brown spots. If tretinoin treatment is not enough, then prevailing conditions depth chemical peels and some non-invasive lasers can help build collagen and thus revolutionize the skin's appearance.
