My dermatologist recently gave me a prescription for Retin A. On the tube it says to apply a pea-sized amount to the face once a day. Does this mean just the facial area and not the neck? I am following Dr. B's instructions for adjusting to the product, so I am not applying it daily yet.

Also should I stop applying the product before I have my eyebrows or my lips waxed?

Thanks for your help.
