I think that when it comes to the age process, we can only try to take precautions in order to prevent premature signs.
In my opinion, wrinkles are part of aging gracefully (I heard this in a commercial:o). We can try to lead a healthy and active life and take care of our skin(with whatever products work for us). Legend has it that in Asian countries people consider ginseng as a natural option for delaying aging signs such as wrinkles. Nowdays, people even consider surgery to get rid of them as once they have appeared they may be difficult to make disappear.
How visible aging signs are in a person, may vary, as I think our genes and environment factors play a major role in this process.
