Why Does Collagen, Elastin and Hyaluronic Acid Decline?

Aging skin is one of the more distressing facts of life. At some point, that smooth, supple surface becomes dry, wrinkled and saggy. Many outside factors affect the natural aging process. However, three physiological elements women have in abundance during their youth steadily decline over the years – also contributing to aging skin.

Collagen, elastin and hyaluronic acid (HA) all contribute to supple, healthy and smooth skin, but as women age, natural and environmental factors cause skin cells to gradually lose the ability to produce these important elements. All three layers of the skin – the epidermis, dermis and subcutaneous layers – are affected by the slow decline in these proteins. As a result, the skin begins to thin and become more fragile.


Causes of Aging

There are dual factors in facial aging – internal (age-related) and external (environmental).

Internal factors are caused by genetics, the decline of cellular structures and processes and hormonal changes. These factors lead to wrinkles, fine lines, drooping eyelids, hollowed cheeks, jowls and dry skin. The natural production of collagen, elastin and hyaluronic acid is reduced as women age.

External factors include environmental elements that affect the natural aging process, such as sun damage, pollution, smoking, diet and gravity. Visible effects of these factors also include wrinkles, rough skin, blemishes and pigmentation changes.

Visible Effects

Wrinkles and fine lines are initially caused by facial expressions, but starting as early as the age of 20, the body produces one percent less of collagen in the dermis layer every year. Frown lines grow along the forehead and fine lines and wrinkles become visible on the rest of the face due to the steady decrease in collagen and elastin, both of which work together to keep the skin smooth, supple and flexible. Elastin also provides the skin with the flexibility and elasticity necessary to regain form when stretched or compressed.

By the age of 40, these lines deepen, while eyes and cheeks appear hollower and jowls develop because about 50% of all the HA in the body is located in both the epidermal and subcutaneous skin layers. HA plays an enormous role in cell growth and renewal, as it helps retain water and lubricates the movable parts of the body. These actions keep the skin moisturizer and hydrated.

Above 55 to 60, all the visible aging effects become even more pronounced.

Tips For Healthy Skin

As women age, some are only aware of the visible impact to their faces, necks and décolleté, while the rest of the skin on their bodies also ages, even if not in the same degree, at the same speed. Studies* have shown that maintaining a healthy diet and lifestyle, combined with a regimen of non-invasive Body and Face treatments** may help reduce the appearance of aging skin.
