Why should different facial massage techniques be utilized for different skin conditions?

• Different skin
  types are characterized by differing levels of vascular
  and sebaceous activity
• Thus, the stimulation needs and sensitivity
  levels of a client’s skin, in terms of facial massage,
  can vary significantly according to skin type
• The choice of massage movements to be
  performed during a skin treatment should, therefore, be
  dependent on the client’s skin type
