I’ve seen some products that have the same name but are meant for different skin types(dry,combination,oily). What do they do to the product to make it for certain skin types?
In: Chemistry
A lot of it is marketing (creating more products for more shelf space), but on some level, they just have small changes usually. Say a shampoo is offered in oily, normal, and dry hair. The oily hair one might have the least amount of moisturizers added, and the dry one the opposite, and the normal one in the middle. Usually it’s these extra ingredients that make up the various formulations.
