Yes! To bring the point home, please look closely at the below pictures from an ASPS study on identical twins with different sun exposure histories. Notice the remarkable difference in skin quality and aging. Excessive sun exposure is simply bad for your skin and makes you age faster.

Of course! Your skin is the largest organ in your body, and maintaining its health is just as important as taking care of the rest of yourself. Skin works hard to protect you from the sun, heat and cold. Over time, the environment's harmful effects will begin to show on the outer layer of skin the world sees
And let's not forget...being healthy! Drugs, alcohol, smoking, sugar, coffee, food preservatives, and a poor diet all can affect the 650 sweat glands, 20 blood vessels, and more than 1,000 nerve endings per square inch that serve your skin. These factors can also upset the balance of the 20 million bacteria known to live on your skin's surface.
Eat right, exercise often, don't smoke, don't drink alcohol too much, and don't get stressed out - and you will look younger than you should...
