Skincare Professional Skincare Techniques 1 — Questions and Answers
Question 1: What is microdermabrasion?
- A chemical peel using high-concentration acids
- A mechanical exfoliation procedure that removes the stratum corneum using fine crystals or a diamond tip (Correct answer)
- A laser treatment targeting pigmentation
- An injectable filler procedure
Correct answer: A mechanical exfoliation procedure that removes the stratum corneum using fine crystals or a diamond tip
Microdermabrasion is a non-invasive mechanical exfoliation that uses fine crystals or a diamond-tipped wand to remove dead skin cells and stimulate cell turnover.
Question 2: Chemical peels are categorized by their depth of penetration into which three levels?
- Light, medium, and deep (Correct answer)
- Surface, mid, and full thickness
- Gentle, moderate, and intensive
- Superficial, subcutaneous, and intradermal
Correct answer: Light, medium, and deep
Chemical peels are classified as superficial (light), medium, or deep based on how deeply the chemical solution penetrates the skin layers.
Question 3: Which professional treatment uses fine needles to create micro-injuries in the skin to stimulate collagen production?
- Dermaplaning
- Microneedling (collagen induction therapy) (Correct answer)
- Hydrafacial
- LED light therapy
Correct answer: Microneedling (collagen induction therapy)
Microneedling uses a device with fine needles to create controlled micro-injuries that trigger the skin's wound-healing response and collagen synthesis.
Question 4: What is dermaplaning?
- A deep chemical exfoliation using TCA
- A manual exfoliation technique using a sterile surgical scalpel to remove dead skin cells and vellus hair (Correct answer)
- A laser resurfacing treatment for acne scars
- An enzyme-based facial treatment
Correct answer: A manual exfoliation technique using a sterile surgical scalpel to remove dead skin cells and vellus hair
Dermaplaning uses a sterile scalpel held at a 45-degree angle to physically scrape off dead skin cells and fine vellus hair from the skin's surface.
Question 5: LED light therapy in skincare uses different wavelengths for different benefits. Which color is commonly used for anti-aging and stimulating collagen?
- Blue light
- Red light (Correct answer)
- Green light
- Yellow light
Correct answer: Red light
Red LED light (620–700 nm) penetrates deeper into the dermis to stimulate fibroblasts and promote collagen production for anti-aging benefits.
Question 6: What is the Fitzpatrick skin type classification used for in professional skincare settings?
- Determining moisturizer viscosity requirements
- Assessing appropriate laser, peel, and treatment settings based on UV response and pigmentation risk (Correct answer)
- Measuring skin hydration levels
- Classifying acne severity
Correct answer: Assessing appropriate laser, peel, and treatment settings based on UV response and pigmentation risk
The Fitzpatrick scale helps practitioners determine safe treatment parameters, especially for laser and peel procedures, to minimize pigmentation risks.
