Aging Skin



As we age, the skin loses its elasticity and firmness. This is evidenced by sagging and fine lines and thick. The skin is the body's largest organ and the first line of defense against environmental attack. Maximize your skin health to nourish and moisturize from the inside out


If our concern is to have a healthy complexion, bright and vibrant color or a soft texture, finding the best ways to keep our skin looking amazing is of utmost importance. Our skin shows the world the time, effort and value we take to look her best. External factors such as pollution and internal factors, such as oxidative damage and poor diet often stress the skin. This leaves the skin dry and dull or oily and dirty. As part of the natural aging process, the skin begins to develop deep wrinkles and furrows around the forehead, eyebrows and eyes. The skin loses its natural shine and color.

The main reason that the skin looks old, wrinkled and rough, mottled with dark spots or is not age itself. Instead, it is sun exposure. Compare the outer skin of the arm with the skin at the bottom. What side looks younger? The outside, which receives sun exposure, shows signs of aging much more than the lower surface exposed. This skin damage caused by the sun's ultraviolet (UV) is called photoaging.
Photoaging causes wrinkles, dark spots, and a less youthful appearance. Excessive sun exposure can also lead to more serious conditions, such as premalignant actinic keratoses and malignant lesions such as squamous cell carcinoma, basal cell carcinoma and malignant melanoma. Changes in the skin caused by sun exposure are a little different to the changes resulting from natural aging or "historical". Regardless of sun exposure, everyone has fine lines, wrinkles and sagging skin as they age. But how is largely determined by genetics.
The sun's UV radiation causes erythema and reduces the number of blood vessels supplying nutrients to the skin dermal. Sunlight causes damage to collagen and elastin, which are important for maintaining skin tone. The UV radiation also generates oxidants.
We often hear about the different types of UV radiation. UVA is longer penetrate deeper into the skin, and are believed to be most responsible for the aging of the skin. UVB rays are thought to be more superficial and responsible for sunburn and tanning.
You get both UVA and UVB sun exposure and tanning beds. Advising people that tanning beds can cause skin damage and accelerating skin aging like sun exposure.
