I think this is working:) at least it relaxes all tiny - tiny face muscles and I think that will work away some wrinkles. Well, everything we apply warm, cold, moderate pressure tend to rejuvenate.
By the way, got my slipped disc aggravated after the 4 hour surf:( surf was fun though. But now I almost have to sleep on the shakti mat.
And I decided to contact these people who selling cheap shakti mats on Ebay so I can be the representative. I think it is a good deal to deliver this kind of thing to the people who need it just for $15.... (Thats why I started to teach yoga - because it helped me to survive:)
