A comedone is a clogged follicle (open or closed) while a pustule is an infected, pus-filled lesion

A comedone is a follicle blocked with sebum and dead cells (blackhead or whitehead), whereas a pustule is an inflamed, pus-filled papule caused by bacterial activity.

Question 3

Which contraindication would prevent an esthetician from performing a facial treatment?

Accepted Answer

Broken or irritated skin, active infection, or contagious skin condition

Open wounds, active infections (such as impetigo), or contagious conditions are absolute contraindications that require rescheduling the service.

Question 4

What is the purpose of a galvanic current in an esthetic facial treatment?

Accepted Answer

Drive water-soluble active ingredients deeper into the skin (iontophoresis) or perform desincrustation

Answer

Galvanic current uses direct electrical current for iontophoresis (product penetration) and desincrustation (emulsifying sebum in clogged pores).

Question 5

Which skin type is characterized by shiny appearance, enlarged pores, and a tendency toward blackheads and breakouts?

Accepted Answer

Oily skin

Answer

Oily skin results from overactive sebaceous glands, producing excess sebum that creates shine, enlarged pores, and a comedone-prone environment.
