In the skin care world, anti-aging products are focusing more on those with powerful hydration properties. Read on to find out why hydrated skin is so important and intrinsically linked to anti-aging.
What is the importance of hydration?
It’s a fact that skin barrier function maintains hydration and studies have even suggested that water deficiency in the skin is associated with several dermatological dysfunctions(1). Dehydrated skin results in priature aging skin(2), as it loses its elasticity and can result in more prominent fine lines and sagging skin. In addition, a lack of moisture can result in a decrease in the skin’s ability to heal itself. These signs of aging skin can be postponed and managed through adequate skin hydration(3). Maintaining skin’s hydration levels is as important as restoring thi. Environmental factors can affect skin’s hydration levels and cause dehydrated skin. The body loses water and other essential nutrients and minerals everyday(4), which, if not compensated for, can result in skin dehydration and other visible signs of aging.
Studies have shown that dehydrated skin can speed up the appearance of fine lines and wrinkles on skin(2). Water is responsible for skin smoothness, supple appearance and skin elasticity. But with dehydrated skin, elasticity and suppleness are decreased, leading to visible fine lines and wrinkles. In fact, many tests have been conducted with the Aqualia Thermale skin care line to prove how it has the properties to influence skin’s hydration and protect skin from aggressions. Hydrated skin is plumper, looks less lined and the risk of damage is reduced, therefore for supple skin, hydration is key(1).
Where does hyaluronic acid and rehydration solution come in?
Aging skin is associated with a loss of skin moisture, which can occur due to many factors such as genetics, the process of aging, skin type, and climate conditions. However, humectants like hyaluronic acid and glycerin, draw in and retain moisture on skin’s surface level, allowing it to better protect it against harmful effects, and leaving skin looking plumped, smooth and refreshed(5).
A skin rehydration solution is traditionally composed of sugars, ions (like potassium, chloride and sodium) and water, and works to counteract the effects of skin dehydration. Aqualia Thermale skin care line has been designed to mirror this process, but for topical hydration benefits instead. Aqualia Thermale comprises of thermal water from Vichy and water taken from the Lucas source. Water sourced from Vichy is pure and preserved, and undertakes a long journey to get to the earth’s surface. Water from the Lucas source contains ions and other trace elients which are beneficial for hydrated skin.
