How should I start using the vacuum cup if I have never done cupping massage before? — Massazi glass N8

According to the card, cream or vegetable oil is applied to prepared (warmed) skin, the massage cup is set firmly on the skin and the vacuum is adjusted by feel. The movements are continuous and gliding – straight, circular or zigzag – and the cup must not be held in one place; the procedure lasts 5–15 minutes, taking skin sensitivity into account. The card does not name a special regimen for beginners (frequency of sessions, strength of vacuum).

General information (not a manufacturer's instruction): the skin may redden after the procedure; in case of pain, bruises or feeling unwell, the massage is stopped.
