Your sebaceous glands usually produce less oil each
decade, resulting in poorly-lubricated skin. Such skin
often retains water less efficiently, causing a dry skin
surface. Skin also becomes less elastic with age. As the
collagen and elastin fibers break down, the underlying
skin structure can weaken, causing skin to lose its firm
texture. To counteract this, more frequent moisturizing
or more concentrated moisturizers are needed.
