Two factors that are important to keep skin healthy and youthful includes skin hydration and antioxidant protection. As we age our skin starts to “dry” due to reduced natural oil and moisture retention.
The damage caused by sunlight, with pollution of the environment contributes to the development of free radicals. Although our bodies and our skin, several innate mechanisms to defend against free radicals, this process becomes less efficient as we age.
Clinical studies show that free radicals contribute to age-related diseases and aging itself. Antioxidants may play an important role in helping to reduce, neutralize and eliminate free radical production.
Hyaluronic acid (HA) is one of the skin’s most important components for hydration and moisture retention. The nature of HA’s molecular structure makes it ideal for attracting and holding water. Nearly 50% of the body’s HA is found in the dermis, in the spaces between cells (extracellular matrix). HA along with derma tan sulfate, serves to maintain the water balance in the dermis and adds support for other dermal elements like collagen and elastin.
HA is also highly concentrated at a site of injury (trauma or surgery) to enhance the ability of healing cells to reach an injured area. As we age, our ability to produce sufficient levels of HA diminishes and as a result, the skin becomes drier and more vulnerable to damage.
HA is the material used in the popular injectable expenses such as Restylane ® and Hylaform ®. Local government and the oral supplementation with hyaluronic acid with antioxidants helps to fill the growing shortage of these important nutrients to the skin and improves the management of aging skin.
