Question 1
How does Fitzpatrick Type I skin react to sun exposure?
Answer: Always burns, never tans
Question 2
Where is the stratum lucidum found on the body?
Answer: Palms and soles only
Question 3
How does the skin regulate body temperature through two distinct physiological mechanisms?
Answer: The skin regulates body temperature by activating eccrine sweat glands to cool the body through evaporation, and by dilating or constricting dermal blood vessels to either release or conserve heat as needed.
Question 4
What is the physiological difference between a papule and a pustule in acne lesions?
Answer: A papule is a solid, raised, inflamed bump without pus that results from a blocked follicle causing surrounding tissue inflammation; a pustule is a raised lesion filled with white or yellow pus (dead white blood cells and bacteria) visible at the surface.
Question 5
A client asks why applying sunscreen daily is essential even on cloudy days. Which skin function best explains your answer?
Answer: The skin synthesizes Vitamin D through UV exposure but cannot fully block UVA rays, which penetrate clouds and glass; cumulative UVA damage degrades collagen, causes hyperpigmentation, and increases skin cancer risk even without visible sunburn.
Question 6
How do sebaceous glands contribute to skin health, and what happens when their ducts become blocked?
Answer: Sebaceous glands secrete sebum, an oily substance that lubricates the skin and hair and helps maintain the acid mantle; when their ducts are blocked by dead cells or excess sebum, comedones (blackheads or whiteheads) form and can progress to acne.
Question 7
Why are Fitzpatrick Types IV–VI at higher risk for post-inflammatory hyperpigmentation (PIH) after esthetic treatments?
Answer: Fitzpatrick Types IV–VI have more active melanocytes that overproduce melanin in response to inflammation or trauma, such as aggressive peels or laser treatments, resulting in dark spots known as post-inflammatory hyperpigmentation.
Question 8
Which dermal layer contains dense collagen and elastin?
Answer: Reticular layer
Question 9
During a facial, you notice a client has grade IV cystic acne with deep nodules and significant inflammation. What is the correct course of action?
Answer: Grade IV cystic acne involves deep nodules and cysts with significant inflammation that can cause scarring; the esthetician must refer the client to a physician because this condition is outside the scope of esthetic practice and requires medical treatment.
Question 10
Which epidermal layer contains melanocytes?
Answer: Stratum basale
