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.
Botox is a freeze-dried protein and must be diluted with saline so that it can be injected. This is where you may have heard of the âdilutionâ of Botox. Everyone has to dilute Botox to be able to use it. Typically, 2ml of saline are used which produces 50 units of Botox per ml. The diluted Botox is then placed in syringes so it can be injected. The Cost of Botox is usually associated with the number of units injected. There are well know amounts of Botox typically required for specific areas. The frown lines require 20-30 units, the forehead 10-20 units, and the crowâs-feet (around eyes) 10-15 units per side.
