Question 1: Which factor is the Fitzpatrick skin type primarily based on?

Choices:

1) How the skin burns and tans after sun exposure 2) Natural hair color only 3) The client’s ethnic background alone 4) The amount of visible body hair

Correct Answer: How the skin burns and tans after sun exposure

Explanation: The Fitzpatrick system classi�es skin mainly by its response to ultraviolet exposure, especially tendency to burn and ability to tan. It should not be assigned solely from ethnicity.Page 1

Question 2: During which hair-growth phase is laser hair removal generally most

e�ective?

Choices:

1) Catagen 2) Anagen 3) Telogen 4) Exogen

Correct Answer: Anagen

Explanation: Anagen hairs are actively connected to the follicular structures and contain the most useful melanin target for selective photothermal injury, so they generally respond best.

Question 3: What is the principal chromophore targeted in laser hair removal?

Choices:

1) Water 2) Hemoglobin 3) Melanin 4) Collagen

Correct Answer: Melanin

Explanation: Laser hair removal relies primarily on melanin in the hair shaft and follicular structures to absorb light and convert it to heat.Page 2

Question 4: Selective photothermolysis is best described as:

Choices:

1) Cooling the skin until follicles stop growing 2) Destroying all tissue in the treatment �eld equally 3) Removing the epidermis before applying laser energy 4) Using light that is preferentially absorbed by a target while limiting injury to surrounding tissue Correct Answer: Using light that is preferentially absorbed by a target while limiting injury to surrounding tissue Explanation: Selective photothermolysis uses wavelength, �uence, and pulse duration chosen so the intended chromophore absorbs su�cient energy while surrounding tissue is relatively spared.

Question 5: Laser �uence is commonly expressed in which unit?

Choices:

1) Joules per square centimeter 2) Watts per minute 3) Nanometers per second 4) Millimeters of mercury

Correct Answer: Joules per square centimeter

Explanation: Fluence is energy delivered per unit area and is commonly expressed as joules per square centimeter (J/cm²).Page 3
