This is why I especially like the exercises I got from Fumiko who is the creator of the Face Yoga Method. I happen to stumble upon her youtube channel while browsing through some videos on youtube. Fumiko also has a membership site which seems very good from what I can tell so far, but she actually offers a free webinar which I have taken, as well, if you want to check things out first. Her youtube channel also has a lot of great videos too that can give you a good start on things if you want to try some of her exercises.
Here are a couple of my favorite exercises from Fumiko's Face Yoga Method that you can do anywhere whether you are at home or traveling. I still have a long way to go, but I could a see a difference once I started doing her exercises, so I do these everyday now. Besides, I think these are just fun to do, and I can do these anywhere so that makes it very easy for me, and hey, at my age, I'll take easy! :)
