1x sensitive tip for regular treatment 1x normal tip for mild treatment We advise to use 'Sensitive' treatment tip during the first treatments to see how your skin reacts. If the skin reacts well to the 'Sensitive' tip, you can try the 'Normal' treatment tip. Dead skin cells are effectively and painlessly removed and also the skin is stimulated to regenerate. In combination with the repair and care cream you achieve an optimal result.
