b. rosacea
c. milia
d. acne

Answer 1

The pearly white, keratin-filled cysts forming under the skin are known as milia, which are small, dome-shaped, and not related to clogged hair follicles like acne.

Step-by-step explanation:

Pearly white, enclosed keratin-filled cysts which form a hard ball beneath the outer layer of the skin are known as milia. Unlike acne, which occurs when hair follicles become clogged by shed skin cells and sebum, creating lesions such as whiteheads or blackheads, milia are small, dome-shaped bumps that are typically white or yellow, and they are not a result of clogged hair follicles. Instead, they are tiny cysts that are filled with a protein called keratin and tend to occur on the face, often in clusters.
