If one is looking for the virus then nasal or nasopharyngeal swabs are preferred. Serum or plasma can be used for detection of antibodies to the virus. When we incorporate serums into our routine, we can enjoy a range of benefits, from hydration and brightening to reducing hyperpigmentation and improving skin texture.
Usually sold in smaller bottles and concentrates, serums make a colorful display at beauty supply and skincare stores. A hair serum offers many of the same benefits, but for our locks.
As hairstylist and makeup artist Jules Annen explains, a hair serum is a concentrate for our hair with specific ingredients that boost hair features, from texture and shine to overall vitality.

Maybe you would like a more radiant complexion. Whatever your issue, here are the most common serums recommended by dermatologists. What it does: Free radicals lurk in the air and are found in pollution. They contribute to dull, lifeless complexions. They also can reveal aging—lines and wrinkles—when not addressed.

For best results, Dr. Though it is often overlooked, and sometimes confused for a lightweight cosmetic product, blood serum is incredibly important in the world of medical research and treatment. While the term 'serum' can refer to a number of bodily fluids, it is most often used in reference to the clear liquid that remains after blood coagulates and forms a clot. Serum and plasma are closely related, and similar enough that they are confused for one another, but have different uses.
Blood serum is the clear liquid that remains after blood clots. Serum in a body is a component of plasma, as blood plasma is composed of a combination of both serum and coagulants. However, when separated from those coagulants through the use of a centrifuge, serum can be used to conduct a number of medical tests, and it can also be used to develop antiserum — used to help transfer resistance to disease from one body to another.
Blood serum and blood plasma are commonly confused for each other, for good reason: serum is a component of plasma. Both are the liquid medium that blood cells move through, but the core difference is the presence of the coagulants that allow blood clots to form. When those coagulants are present, the liquid is referred to as plasma, but when removed, what remains is serum alone.
This is effectively the serum definition in biology.
