Try doing facial exercises on a daily basis. I don't know if there are any good sites with an entire 'program' for free, but I recently purchased a program online for about $20.00 which includes exercises for forehead wrinkles, crow's feet, dark circles and bags under the eyes, droopy eyelids, the 'smile' line around the mouth, wrinkles around the lips, and 'turkey neck' sagging. I have done the exercises for two days now and can already notice a very slight difference in the forehead. I only have fine lines as I'm still a few years from turning 30, but I am definitely seeing a slight difference. The exercises, if done properly, work as the muscles in the face become stronger and more defined and start to 'push' the wrinkles out. The more defined muscles will soon start to lift sagging skin, such as over the eyes, giving your face a more youthful appearance. Some 'professionals' in skin care will tell you that the exercises will actually exagerate aging, but that's far from the truth. According to what I've read, if you have deep wrinkles, such as forehead lines, as the muscles becomes stronger it's actually going to sort of stretch out the wrinkles, making them appear wider. But they will eventually get 'pushed' out as the muscle grows and becomes more defined. I have also read that dabbing lemon juice around the eyes can reduce the look of lines and crow's feet. It may take a few weeks for visible results.
