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.
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.sually, the price per unit is advertised. In that way you at least know how many units of Botox you are getting. There are some practices that charge by area. This practice should probably be avoided since you do not know how much Botox you are receiving or the price per unit.
