Young skin appears firm, smooth, and fully hydrated. Over the years, skin may dry out due to sun damage and loss of hyaluronic acid, depleting it of moisture and elasticity at your neckline and décolletage.
As your natural levels of hyaluronic acid diminish, skin looks dull and wrinkled, and feels dry to the touch. This especially affects areas like the face, neck, décolletage and hands. Over-the-counter moisturisers can only do so much and typically do not penetrate deep enough into the skin to create a lasting effect.
