People go to great lengths to keep their skin smooth and wrinkle-free for as long as possible. But a new study has discovered that wrinkles may be predetermined by your genes, no matter what you do. Based within the code of your DNA, certain genes play a part in how your skin ages. "Scientists used data generated by the human genome project (the international effort to decode human DNA) and found 1,500 separate genes that determine how long people's skin will stay smooth" reports Daily News. The study also pointed out that lifestyle can speed up or slow down the aging process as well. Even if your genes predict how quickly your skin ages, antioxidants in your skin can help fight off the wrinkles. Antioxidants from food or beauty products help boost your skin's natural defense system. The skin is then stronger in the fight against free radicals in the atmosphere as well as your own genetic predisposition.
