We teach a complete jaw series as well as a workshop for the eyes. These things are not typically a part of the daily in-class sequencing. However once learned it is completely appropriate for the student to do these things in their home practice as a daily preventive or maintenance.
When a yoga practice is robust the student is taught how to manage their nutrition in such a way as to maintain or keep up their physical body including the flesh and the smaller muscles. A person who is not properly hydrated, who is not properly oxydated, who is not properly leaning their diet toward alkaline rather than acidic foods, that person could do all the "face yoga" under the sun and it would matter very little.
