Electrolysis Final Exam Questions & Answers
In 1875, it was first reported that Dr. Charles E. Michel, a St. Louis ophthalmologist, was using galvanic electrolysis to treat what? - ✔✔Patients with ingrown eyelashes.In 1916, Multiple Needle (16) galvanic electrolysis machine was created by who? Used in DC only. - ✔✔Paul Kree In 1924 Dr. Henri Bordier unveiled what? - ✔✔His Radio Frequency epilator, creating what we call Thermolysis.Mildred Trotter published a study proving what? - ✔✔Shaving has no effect on hair growth. 1928 Arthur Hinkle and Henri St. Pierre created what in 1945? - ✔✔The first Blend epilator.In Florida, a person who holds ONLY an electrologist license is not allowed to practice what? - ✔✔Anaphoresis When performing Electrolysis, what chemical is made at the cathode? - ✔✔-Lye -Sodium Hydroxide -NaOH -Hydrogen Gas When performing Electrolysis, what chemical is made at the anode? - ✔✔-Hydrochloric Acid -Chorline Gas (very little) What are the two and only two factors for determining the Units of Lye made? - ✔✔Time X Intensity = Lye Neither needles nor depth of insertion have any influence on the amount of lye made in the follicle.How much Lye would be made if we ran DC at .4mA for 15 seconds? (Time X Intensity) - ✔✔60UL (4 x 15) What is the difference, if any, with regards to lye and depth of insertion? - ✔✔A shallow insertion will have a greater lye concentration, and a deeper insertion will have a lower lye concentration.What is unique about an insulated needle? - ✔✔Only allows current to exit the very tip of the needle.What is the working point? - ✔✔Working as close to the patient's pain threshold as possible, thus ensuring the greatest intensity possible, and shortest epilation time possible.Used in Thermolysis What is Point Effect? - ✔✔Refers to the phenomenon that the heating pattern ALWAYS starts at the tip of the needle. The ideal heating pattern has the heating starting at the tip of the needle and working its way up the needle in uniform rate. 1 / 3
What removal modality involves using an electrical current to create a chemical in the tissue? - ✔✔Electrolysis Galvanic Galvanic Electrolysis Multiple Needle Direct Current (DC) Which hair removal modality involves using an electrical current to create heat in the tissue? - ✔✔Thermolysis Alternating Current (AC) Short Wave Radio Frequency High Frequency Diathermy What hair removal technique requires the use of two hands? - ✔✔PEST ( Post Epilation Sustained Entry Technique) With what modalities may we use PEET, PERT, PEST? - ✔✔Electrolysis, Thermolysis and Blend What is the name that we give to the way in which DC destroys a follicle's ability to grow new hair? - ✔✔Chemical Decomposition What are the names that we give to the way in which AC destroys a follicle's ability to grow new hair? - ✔✔Electrocoagulation and Electrodessication What does The Blend use? - ✔✔Electrolysis and Thermolysis Describe Flash Thermolysis. - ✔✔"High intensity - Short timing" (1/10 of a second) Smaller needles (thinner diameter) are "hotter" than larger needles (thicker diameter) meaning... - ✔✔Smaller needles create a larger/more intense heating pattern in the tissue vs. larger needles.More shallow insertions are "hotter" than deeper insertions meaning... - ✔✔The more shallow insertions create a larger more intense heating pattern in the tissue vs. deeper insertions.What could lead to a pitting scar by tearing the tissue? - ✔✔Using too small of a needle (while using RF) What is the most common material used for needles? - ✔✔Stainless steel What is the best shape for a needle? - ✔✔Tapered What needles are best to buy? - ✔✔Disposable What may a bruise also be called? - ✔✔Eccyhymosis Purpura 2 / 3
What are the functions of the skin? - ✔✔Protection Heat Regulation Respiration Absorption PHRASE Sensation Elimination How many layers does the skin have and what are they? - ✔✔2 Dermis Epidermis How many layers does the epidermis have and what are they? - ✔✔5 Stratum Corneum Stratum Lucidum Stratum Granulosum Stratum Spinosum Stratum Germinativum What is the name for sweat glands and what are the sub-types of sweat glands? -
✔✔Sudoriferous glands: eccrine and apocrine
What is hypertrichosis? - ✔✔A condition of excessive hair on a woman, but in places where it would be normal for her to have hair.What is Hirsutism? - ✔✔Male pattern hair on a woman caused by androgens.What are the stages of the hair growth cycle, and in which do we have the best chance to disable a follicle's ability to grow a hair? - ✔✔ACT AGAGEN- growing stage, the hair bulb is connected to the papilla. (best stage to disable follicle/ late anagen) CATAGEN- transition stage, the hair bulb is beginning to separate from the papilla--a 'club hair" begins to form.TELOGEN- resting or dormant stage, the hair bulb has separated from the papilla.What are the two main classifications of hair? - ✔✔Vellus and Terminal What are 3 other types of hair? - ✔✔ASEXUAL- hair common to males and females that is not stimulated by androgen.AMBOSEXUAL- hair common to males and females that is stimulated by androgens.SEXUAL- male hair patterns, stimulated by androgens.
