Dry skin

Another secret sign of aging is dry and thinning skin. 

Dr Martin-Herranz explains: "The outer layers of the skin contain less water with aging and as a consequence skin has a tendency to become drier. This can be visually perceived as a drier surface and also a dull skin appearance."

To keep your skin plumped up, and well hydrated, try using a intensive topical moisturizer during the day - and a facial oil at night to combat dehydration lines.
