In order to explain the ecological approach in the learning process, we. present its underlying principles and analyse them in relation to existing learning design frameworks. To formalize. our approach, we define the basic concepts and propose a general framework for constructing learning paths.
Most women need 20-25 units for the treatment of frown lines. However, men may need 35 units because the bulk of muscle to be weakened is larger. BotoxÂ® prices nationwide average between $10 and $15 per unit.
To counter this down turn, BOTOX Â® may be injected just into the muscles just beneath the eyebrows. If the only desire is to lift the eyebrows a small amount, then a small amount of BOTOX Â®, perhaps 2 or 2.5 units of BOTOXÂ® may be injected just beneath each eyebrow. It is important to point the injection needle superiorly to avoid downward dispersement of the BOTOXÂ®. Sigmund L. Sattenspiel, MD.
