No. Hypnosis is a naturally occurring state of concentration which enhances your control over your own mind and body. During hypnosis, blood flow is increased in the right anterior cingulate cortex, creating heightened internal focus. Your surrounding environment becomes less distracting, allowing you to focus more intently on your goal.
All hypnosis is self-hypnosis. A hypnotist cannot make you do or say or believe anything against your will. You cannot be forced into accepting or enacting any suggestion that violates your beliefs. You always remain in control and are awake and alert the whole time. The mind has natural defenses against harmful suggestions and will reject any undesired suggestions automatically. It will always protect itself.
