The vacuum created by the cup gives your facial muscles a proper workout and may cause temporary redness, which is completely normal due to increased blood flow in the treated area. This usually fades shortly after treatment. Minor side effects such as dizziness, nausea, or slight discomfort in the face may occur after treatment. Always start gently and avoid overdoing it. If you experience bruising on the face after cupping, this may indicate that the suction was too strong for your skin, that the treatment lasted too long, or that the cup was left in one place. It is important to use light pressure and start carefully, with 1 to 3 strokes per area. Always keep the cups moving using soft, gliding motions. To avoid bruising in the future, begin with lighter suction and gradually increase as your skin adapts to the treatment. Make sure to use a good facial oil to help the cups glide smoothly and to nourish the skin. We recommend Curam Face & Massage oil.
