Control device and method of portable skin beautifying apparatus

A control method of a portable beautifying apparatus comprising:

• a first step performing an initializing operation by turning on an electric power and determining whether or not a key signal is input;
• a second step setting a skin beautifying step according to the key signal when the key signal is input in the first step and performing skin measurement;
• a third step performing the skin measurement when the key signal is not input in the first step but the skin measurement is being performed, and determining a present beautifying step when the skin measurement is not being performed and performing a beautifying operation;
• a fourth step alternatively outputting a discrete positive galvanic ion current having a first frequency and a consecutive positive galvanic ion current for a first time period when the beautifying step determined in the third step is a cleansing step, and simultaneously setting a massage step after outputting far-infrared ray and vibration operations;
• a fifth step repeatedly outputting a discrete positive galvanic ion current, a discrete negative galvanic ion current, and a positive and negative alternating galvanic current for a second time period each of which has a second frequency when the present beautifying step determined in the third step is the massage step, and setting a nutrition supply step after outputting far-infrared ray and vibration operations;
• a sixth step repeatedly outputting a discrete negative galvanic ion current having a third frequency and a consecutive negative galvanic ion current for a third time period when the present beautifying step determined in the third step is the nutrition supply step, and setting a lifting step after outputting far-infrared ray and vibration operations;
• and
• a seventh step repeatedly outputting a positive and negative alternating galvanic ion current varied for a selected time within a set frequency range when the present beautifying step determined in the sixth step is the lifting step, and ending the skin beautifying steps after outputting far-infrared ray and vibration operations.
