Will Bikram Yoga Affect my Restylane Injections?

I would not suggest you do the hot yoga the day of the procedure as it might induce more bruising but it won't degrade the material.  Studies have not shown that lasers affect the filler when the laser is performed after the fillers are placed.

While it may not speed up the break down of the Restylane.  Part of the effect of Restylane comes from the tissue water that is tied up with the Restylane.  I do not need to tell you that Bikram Yoga is stressful on the body.  On can loose up to 1/2 gallon of water doing a session of Bikram yoga.  The associated shifts in body water could cause some fluctuation in how full your face looks at the end of a session compared to how you looks hours later with recovery and rehydration.  SInce this subject is not really studied, you personal observations might be of interest to others in your situation.

There should be no issue with doing Bikram Yoga after having Restylane injections.  Excessive sweating should have no effect on the product.
