It's only skin deep and what you do now could determine how you will look later.
Turning to what is essentially a modern-day magic mirror, a skin analysis machine can tell them what's going on underneath their skin.
The machine takes a 3-D snapshot and compares it to 5,000 people of the same age and skin type. Patients can see sun damage, pore size, wrinkles and bacteria. It can also show you what you'll look like in 10 years.
The right treatments can slow aging down, but Dr. Barry Dibernardo of New Jersey Plastic Surgery says there are a lot of things we do wrong.
"We can see certain things with our eyes, but we can't see below the surface," Dibernardo said.
Collagen is one way to deal with wrinkles.
"Just by taking a molecule and putting it on the surface doesn't mean that it gets under the skin," Dibernardo said.
Higher sunscreen SPF numbers over 30 filter out slightly more UVB rays and can add up over time.
A study out of India found facials cause breakouts in 80 percent of people.
And one recent study found participants who consumed five tablespoons of tomato paste daily for three months had nearly 25 percent more protection against sunburn.
Dibernardo says your best bets to help you look younger are lasers, fillers and other therapies your doctor can prescribe. The skin analysis typically costs about $100.
