What type of bacteria are responsible for causing skin infections such as acne vulgaris?
Propionibacterium acnes
In which stage of the bacterial life cycle is a bacterium most resistant to environmental stress?
The spore stage
Which sanitation method involves using chemicals to reduce pathogens on non-living surfaces?
Disinfection
What is the primary function of the stratum corneum in the skin?
To act as a barrier protecting underlying tissues
Which skin layer is primarily responsible for thermoregulation?
The dermis
What is the primary purpose of using antiseptics in esthetic treatments?
1
, To reduce the number of microorganisms on the skin
How do endotoxins produced by bacteria affect the skin?
They can cause inflammation and trigger immune responses
Which type of bacteria is generally considered beneficial and is part of the skin microbiome?
Lactobacillus
What is the main difference between sterilization and disinfection?
Sterilization eliminates all microorganisms, while disinfection reduces them to safe levels.
Which vitamin is essential for proper skin cell function and repair?
Vitamin A
How does UV radiation affect skin physiology at the cellular level?
It causes DNA damage, leading to premature aging and skin cancer.
What is the pH range considered normal for healthy skin?
4.5 to 5.5
Which type of cell is responsible for the production of melanin in the skin?

, How does smoking affect skin physiology?
It reduces blood flow, leading to premature aging and wrinkles.
What role do probiotics play in skin health?
They help maintain a balanced skin microbiome, preventing harmful bacteria overgrowth.
How can the stratum granulosum layer of the epidermis influence skin hydration?
It produces lipids that help retain moisture.
What is the process by which the body’s immune system responds to pathogens on the skin?
Inflammatory response

To check for allergic reactions or sensitivities
What type of bacteria is often found in biofilms on the skin, contributing to chronic skin
conditions?
