Once the skin is ready, 3-4 ml of the solution is added throughout the face or area to be treated and allowed to act according to the estimated times below. Rosacea or Couperose: 5-10 min. Exposure times are approximate and only indicate general guidelines. Adjustment according to skin type and subsequent care are at the discretion of the professional. If signs of irritation, redness or itching appear, remove immediately with water. In case of rosacea or couperose we do not recommend a massage, especially in the most sensitized areas. In the case of neck and décolleté, perfomr a gentle massage for 2-5 minutes.
