The Importance of HA, Decade After Decade


Normal, healthy skin begins to lose hyaluronic acid (HA) shortly after birth. As early as age 20, the skin has already lost half of its essential HA supply. This decline continues gradually until age 50 and then progresses more rapidly. When HA is lost, the skin cannot retain the water it requires at the cellular level. The dehydrated structure of the skin begins to collapse. Folds, which appear as fine and deep lines, trap dead cells that are sloughed off. Normal cell turnover decreases significantly. Blood flow and lymphatic drainage are affected, reducing nourishment to the skin and removal of waste products from the skin. The result is unhealthy skin, diminished in tone, texture, color and radiance. The natural loss of the HA-water complex is further affected by stress, environmental conditions, nutrition and general lifestyle.
