Serum Meaning in English
word
释义
Serum is the clear, yellowish liquid part of the blood that remains after clotting, often used in medicine and scientific research. It can also refer to a liquid beauty product applied to the skin.
用法与细微差别
'Serum' is scientific and medical, but also common in skincare ("vitamin C serum"). The medical meaning is uncountable; in cosmetics, can be countable ("a serum"). Don't confuse with 'serum' as a synonym for 'vaccine'—it is not the same.
