Green and white tea
Started drinking green and white tea, three to five cups a day to protect your skin. Research has shown both types of tea have protective properties, such as EGCG and theaflavins, which can help prevent skin cancers and the breakdown of collagen, this is the primary cause of wrinkles.

Strength training
Strength-training, is vital, especially the older you get. The key benefits include firmer skin neck down, as well as better, more supportive muscle tone. It is the equivalent of adding volume to your skin, except on your body.

Watch that Sweet Stuff
The process of breaking down glycation, can damage your collagen, this keeps skin smooth and firm. To avoid, or limit the process from getting out of control, try to keep to low-glycemic carbs such as whole grains; these are naturally in low in sugar, and the body processes it slower to limit the loss of collagen.
