2 MILADYS Standard Instructor Support Slides COSMETOLOGY Competition is a by-product of productive work, not its goal. A creative man is motivated by the desire to achieve, not by the desire to beat others Ayn Rand

3 MILADYS Standard Instructor Support Slides COSMETOLOGY Objectives Define the nature of electricity and the two types of electric current.. Define electrical measurements. Understand the principles of electrical equipment safety. Define electric modalities used in cosmetology.

4 MILADYS Standard Instructor Support Slides COSMETOLOGY Objectives Explain electromagnetic radiation and the visible spectrum of light. Describe the types of light therapy and their benefits.

5 MILADYS Standard Instructor Support Slides COSMETOLOGY Electricity Electric current Conductor

6 MILADYS Standard Instructor Support Slides COSMETOLOGY Insulator Nonconductor – does not easily transmit electricity –Rubber –Silk –Wood –Glass –Cement Complete circuit

7 MILADYS Standard Instructor Support Slides COSMETOLOGY Types of Electric Current Direct current (DC) Alternating current (AC) Converters Rectifiers

8 MILADYS Standard Instructor Support Slides COSMETOLOGY Electrical Measurements Volt: measures pressure Ampere: measures strength Milliampere: 1/1000 th of an amp Ohm: measures resistance Watt: measures energy used in 1 second Kilowatt: equals 1000 watts

9 MILADYS Standard Instructor Support Slides COSMETOLOGY Safety Devices Fuse Circuit breaker

10 MILADYS Standard Instructor Support Slides COSMETOLOGY Electrical Equipment Safety Inspect regularly Dont overload circuits Check for UL approval Ensure appliances are grounded

11 MILADYS Standard Instructor Support Slides COSMETOLOGY Hints for Safety Ensure UL certification Read instructions Disconnect when not in use Inspect equipment regularly Keep wires, plugs, equipment in good repair Use one plug per outlet

12 MILADYS Standard Instructor Support Slides COSMETOLOGY Hints for Safety

13 MILADYS Standard Instructor Support Slides COSMETOLOGY Avoid contact with water or metal Dont leave client Keep cords off floor Dont clean area when plugged in Dont touch 2 metallic objects if either is connected to current Hints for Safety

14 MILADYS Standard Instructor Support Slides COSMETOLOGY Dont step on or set objects on cords Dont let cords become twisted or bent Pull plug, not cord Dont repair unless qualified Dont force plugs into outlets Hints for Safety

15 MILADYS Standard Instructor Support Slides COSMETOLOGY Electrotherapy Electrotherapy: electronic facial treatments Wall plate Modalities Electrodes

16 MILADYS Standard Instructor Support Slides COSMETOLOGY Polarity Positive pole (anode, red) Negative pole (cathode, black) Test one Test two

17 MILADYS Standard Instructor Support Slides COSMETOLOGY Polarity Test One Separate tips and immerse in saltwater Set on galvanic current and turn up intensity As water is decomposed, more active bubbles will accumulate at negative pole

18 MILADYS Standard Instructor Support Slides COSMETOLOGY Polarity Test Two Place conducting cord tips on blue moistened litmus paper Paper under positive pole will turn red Paper under negative pole will stay blue

19 MILADYS Standard Instructor Support Slides COSMETOLOGY Galvanic Current Active electrode Inactive electrode

20 MILADYS Standard Instructor Support Slides COSMETOLOGY Positive Pole Results Acidic reactions Closes pores Soothes nerves Decreases blood supply Contracts blood vessels Firms tissues Pulls acid solutions into skin

21 MILADYS Standard Instructor Support Slides COSMETOLOGY Negative Pole Results Alkaline reactions result Opens pores Stimulates nerves Increases blood supply to skin Expands blood vessels Softens tissues Softens and liquefies grease deposits Forces alkaline solutions into skin

22 MILADYS Standard Instructor Support Slides COSMETOLOGY Iontophoresis Cataphoresis Anaphoresis Desincrustation

23 MILADYS Standard Instructor Support Slides COSMETOLOGY High-Frequency Current Tesla: commonly called violet ray Benefits –Stimulates blood circulation –Increases glandular activity –Aids in elimination and absorption –Increases metabolism –Improved germicidal action –Relieves congestion

24 MILADYS Standard Instructor Support Slides COSMETOLOGY Other Electrical Equipment Hood dryers or heat lamps Curling or flat irons Heating caps Processing or accelerating machines Steamer or vaporizer

25 MILADYS Standard Instructor Support Slides COSMETOLOGY Light Therapy Visible light –Electromagnetic radiation –Wavelength –Long wavelengths –Short wavelengths

26 MILADYS Standard Instructor Support Slides COSMETOLOGY Electromagnetic Spectrum Visible light (35% of natural light) Ultraviolet and infrared rays Visible spectrum

27 MILADYS Standard Instructor Support Slides COSMETOLOGY Infrared Rays 60% of natural sunlight Long wavelengths Deepest penetration Produce most heat Lamps should be 30 from skin 5-minute exposure time Check client comfort frequently Never leave client unattended

28 MILADYS Standard Instructor Support Slides COSMETOLOGY Visible Light Rays White light Blue light Red light

29 MILADYS Standard Instructor Support Slides COSMETOLOGY Ultraviolet Rays Ultraviolet Rays – 5% of natural sunlight Short wavelengths Penetrate the least Produce chemical effects Kill germs

30 MILADYS Standard Instructor Support Slides COSMETOLOGY Ultraviolet Disadvantages Can cause skin cancer 1,000,000 cases diagnosed annually 1 in 5 Americans will develop skin cancer 90% result from UV radiation and tanning beds

31 MILADYS Standard Instructor Support Slides COSMETOLOGY Ultraviolet Ray Application Lamp should be 30 – 36 from skin 2 – 3 minute exposure initially Increase to 7 – 8 minutes Avoid overexposure Never leave client unattended

32 MILADYS Standard Instructor Support Slides COSMETOLOGY Light and Heat Energy – Nail Technology Catalysts UV light

33 MILADYS Standard Instructor Support Slides COSMETOLOGY Summary and Review Describe the 2 types of electric current and give examples of each List 4 main types of electrical measurements. What do they measure?

34 MILADYS Standard Instructor Support Slides COSMETOLOGY List and describe 2 main electric modalities or currents used in cosmetology List and describe 2 main types of light therapy Summary and Review

35 MILADYS Standard Instructor Support Slides COSMETOLOGY What is electromagnetic radiation? Name 2 important precautions to observe when using light therapy Summary and Review

36 MILADYS Standard Instructor Support Slides COSMETOLOGY Congratulations! Youve just completed one unit of study toward program completion!
