In my holy/honest/humble opinion. A rephrasing of imo. Used in net-speak (read: retarded), it's mainly used to attempt to show that the opinion stated was either godly, true, or was stated by someone with humility. All three of those reasons are what would be simply known as bullshit. Retard1: omg imho, ur a fag lol.
CoolSculpting is quite different to Cryosurgery, which uses cold to kill off tissue, such as tumors. Typically cryosurgery uses far lower temperatures (-20c/-4f to -40c/-40f) and immediately kills off the living cells (necrosis) .
Coolsculpting protects skin, muscle, and nerves by precisely controlling the temperature at which the fat is cooled to. Through feedback mechanism, the temperature is maintained over the hour of the cycle to a certain level. Ice applied would give a variable temperature and can cause skin injury.
