Skincare Facial Skincare 4 — Questions and Answers
Question 1: Which AHA (alpha hydroxy acid) is most commonly derived from milk?
- Glycolic acid
- Lactic acid (Correct answer)
- Mandelic acid
- Citric acid
Correct answer: Lactic acid
Lactic acid is an AHA naturally derived from milk and is known for being gentler than glycolic acid while still effectively exfoliating.
Question 2: What makes BHA (beta hydroxy acid) particularly effective for acne-prone skin?
- It is water-soluble and stays on the skin surface
- It is oil-soluble and can penetrate inside pores (Correct answer)
- It kills bacteria on contact
- It reduces oil production immediately
Correct answer: It is oil-soluble and can penetrate inside pores
BHA (salicylic acid) is oil-soluble, allowing it to penetrate into pores to dissolve sebum and dead skin cells that cause blackheads and acne.
Question 3: What is 'slugging' in skincare?
- A deep chemical peel treatment
- Applying petroleum jelly as the last step to lock in moisture (Correct answer)
- Massaging the face with snail mucin
- Using a gua sha tool for lymphatic drainage
Correct answer: Applying petroleum jelly as the last step to lock in moisture
Slugging involves applying a thin layer of petroleum jelly (like Vaseline) as the final step in a nighttime routine to create an occlusive seal that prevents moisture loss.
Question 4: Which skin condition is characterized by chronic facial redness, visible blood vessels, and sometimes bumps?
- Psoriasis
- Eczema
- Rosacea (Correct answer)
- Contact dermatitis
Correct answer: Rosacea
Rosacea is a chronic skin condition causing facial redness, visible blood vessels (telangiectasia), and sometimes acne-like bumps, primarily on the cheeks and nose.
Question 5: What is the benefit of using facial oil in a skincare routine for dry skin?
- It replaces the need for a moisturizer
- It provides occlusive properties to seal in hydration (Correct answer)
- It adds water content to the skin
- It exfoliates dry patches
Correct answer: It provides occlusive properties to seal in hydration
Facial oils act as occlusives by creating a barrier on the skin's surface that locks in moisture from underlying hydrating products.
Question 6: How long should sunscreen be applied before sun exposure for maximum effectiveness?
- Immediately before going outside
- 15-30 minutes before sun exposure (Correct answer)
- 1 hour before sun exposure
- The night before
Correct answer: 15-30 minutes before sun exposure
Chemical sunscreens need 15-30 minutes to absorb and bind to the skin before they can effectively filter UV rays.
Question 7: What is 'purging' in the context of introducing new skincare actives?
- An allergic reaction to a new product
- A temporary increase in breakouts as skin cell turnover accelerates (Correct answer)
- Skin peeling from over-exfoliation
- The process of detoxifying the skin
Correct answer: A temporary increase in breakouts as skin cell turnover accelerates
Purging is a temporary breakout phase when using actives like retinoids or AHAs, caused by accelerated cell turnover pushing clogged material to the surface faster.
