The meaning being:


(SEER-um) The clear liquid part of the blood that remains after blood cells and clotting proteins have been removed.

What does a serum do?

Serums can target specific skin concerns, such as acne, dryness, and aging. They can also improve skin texture, reduce the appearance of fine lines, and protect the skin from environmental damage.



Wikipedia: Serum (/ˈsɪərəm/) is the fluid and solvent component of blood which does not play a role in clotting.[1] It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed.

Serum contains all proteins except clotting factors (involved in blood clotting), including all electrolytes, antibodies, antigens, hormones; and any exogenous substances (e.g., drugs, microorganisms).

Serum also does not contain all the formed elements of blood, which include blood cells, white blood cells (leukocytes, lymphocytes), red blood cells (erythrocytes), and platelets.[citation needed]

Why is it included in health products?

The "serum" in cosmetics is NOT a blood product or human-derived in any way.

I believe the manufacturers are simply describing some kind of liquid with protein or protein like components.

It sounds scientific, so it sells!

That's what DH thinks.  Why not tell the customer what it is made of?

Ingredients will be listed on the product label. Unless you are a cosmetic scientist or work in the industry however the ingredients won't mean much. But serum is just a word with multiple applications.

Such as though?  My husband is a Research Chemist ;-). 

'serum' is from blood products ............ but probably sounds 'healthy' to those who never question what they put onto their skin or swallow? 

It surprises me that many women query HRT prescriptions but do they check everything that they eat/drink/apply?

An example of a retinol serum ingredient list:
Water (aqua / eau),glycerin,butylene glycol,propanediol,dicaprylyl carbonate,tocopherol,hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer,squalane,polysorbate 60 ,sorbitan isostearate ,phenoxyethanol ,caprylyl glycol,phospholipids,glycine soja (soybean) oil,glycolipids,glycine soja (soybean) sterols,retinyl acetate,dimethicone,leuconostoc/radish root ferment filtrate,hyaluronic acid,dimethyl isosorbide,hydroxypinacolone retinoate,carbomer,glycerin,butylene glycol,carbomer,polysorbate 20 ,palmitoyl tripeptide-1,palmitoyl tetrapeptide-7,sodium lactate,tocopheryl acetate,tetrasodium glutamate diacetate,sodium hydroxide,sodium hydroxide,tetrahexyldecyl ascorbate.

No blood as far as I'm aware. 

Agree though, we put cosmetics on our skin and bodies without too much thought unless we know we are allergic to a specific ingredient. 
A lady I know will have nothing to do with HRT incase she gets cancer BUT refuses to stop smoking 🙄

Serum doesn't only apply to blood products. The word serum comes from Latin and the literal translation is 'watery fluid' or 'whey'. 

This is taken from a medical dictionary --

Serum: The clear liquid that can be separated from clotted blood. Serum differs from plasma, the liquid portion of normal unclotted blood containing the red and white cells and platelets. It is the clot that makes the difference between serum and plasma.
The term "serum" also is used to designate any normal or pathological fluid that resembles serum as, for example, the fluid in a blister.

"Serum" is a Latin word that refers to the "whey", the watery liquid that separates from the curds in the process of cheesemaking.

That clears that one up then
