Foods marked with bio are generally organic foods, which are much more expensive than ordinary foods.
Cosmetics marked with bio refer to cosmetics made of pure natural raw materials.
As far as I know, they use the "biological" logo very strictly.
Food in China is labeled as "green food" and "organic food".
But cosmetics seem to have no natural logo.
The function of the word "biology" mentioned by the landlord in cosmetics is actually used by manufacturers as a fashionable advertising word.
Its real brand name needs to be carefully searched to see if it is behind bio.
