it's because serums are treatment and it's more interesting for a brand to invest money into research and development for this type of product than in a cleanser or a moisturizer whom formulas and uses won't allow the actives to work at their best anyway.

Well because fash washes have their own main function like cleansing your face or moisturizer to moisturize your skin.
But serum is just a general term.
However nowadays there are a lot of cleansers and moisturizers that have more than one function like cleansers with SA.
