Question 1: Hyperpigmentation caused by sun exposure is best described as:
- Vitiligo
- Solar lentigines (sun spots) (Correct answer)
- Rosacea
- Seborrhea
Correct answer: Solar lentigines (sun spots)
Solar lentigines are flat, darkened patches caused by cumulative UV exposure that stimulates localized melanin overproduction.
Question 2: Which SPF value is recommended by the American Academy of Dermatology for daily use?
- SPF 10
- SPF 15
- SPF 30 or higher (Correct answer)
- SPF 100
Correct answer: SPF 30 or higher
The AAD recommends at minimum SPF 30, which blocks about 97% of UVB rays, for adequate daily sun protection.
Question 3: A microdermabrasion treatment exfoliates the skin using:
- Alpha hydroxy acids applied under occlusion
- A rotating vacuum tip with fine crystals or a diamond-tipped wand (Correct answer)
- High-frequency electrical current
- Enzyme-based creams left on for 20 minutes
Correct answer: A rotating vacuum tip with fine crystals or a diamond-tipped wand
Microdermabrasion mechanically abrades the stratum corneum using aluminum oxide crystals or a diamond-tipped applicator combined with suction.
Question 4: What skin condition is characterized by chronic redness, flushing, and visible blood vessels on the face?
- Psoriasis
- Rosacea (Correct answer)
- Perioral dermatitis
- Seborrheic dermatitis
Correct answer: Rosacea
Rosacea is a chronic inflammatory skin condition causing facial redness, flushing, telangiectasia, and sometimes papules on the cheeks, nose, and forehead.
Question 5: The Langerhans cells found in the epidermis serve which function?
- Produce sweat to cool the skin
- Act as immune sentinels that detect and respond to antigens (Correct answer)
- Synthesize collagen and elastin fibers
- Regulate sebum production in follicles
Correct answer: Act as immune sentinels that detect and respond to antigens
Langerhans cells are dendritic immune cells in the epidermis that detect foreign substances and initiate an immune response.
Question 6: Which mask type is most appropriate for a client with oily, acne-prone skin?
- Paraffin wax mask
- Cream-based hydrating mask
- Kaolin or bentonite clay mask (Correct answer)
- Collagen sheet mask
Correct answer: Kaolin or bentonite clay mask
Clay masks absorb excess sebum, minimize the appearance of pores, and can help draw out impurities from oily and acne-prone skin.
Question 7: In the context of skin care services, what does the term 'emollient' mean?
- An ingredient that removes surface dead skin cells
- A substance that softens and smooths the skin by filling spaces between skin cells (Correct answer)
- A product that reduces melanin production
- A formula that tightens and firms loose skin
Correct answer: A substance that softens and smooths the skin by filling spaces between skin cells
Emollients fill in the gaps between skin cells in the stratum corneum, smoothing rough texture and improving the skin barrier's integrity.
