Question

Which of the following can be categorized as part of your skin's "Chemical Barriers"?

a) Sebum production
b) Melanin levels
c) Sweating
d) Acidic pH of sweat

Answer 1

Sebum production, melanin levels, sweating, and the acidic pH of sweat are all part of the skin's chemical barriers.

Step-by-step explanation:

The skin's chemical barriers include sebum production, melanin levels, sweating, and the acidic pH of sweat.

Sebum is produced by sebaceous glands and acts as a natural moisturizer and protection against bacteria.

Melanin, a pigment produced by melanocytes, helps protect the skin from the harmful effects of UV radiation.

Sweat, produced by sweat glands, contains antimicrobial substances that can destroy pathogens on the skin's surface.

The acidic pH of sweat acts as a barrier to bacteria, viruses, and other potential contaminants.
