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 was designed to kill fat cells by bringing the fat to a specific temperature. The temperature it takes to freeze the fat cells is much higher than the temperature of freezing or damaging the skin. The skin is proctected during the treatment.
