Hi, sorry but I have to "interrupt" a bit. Moisturizers are the products but it's not like humectant, emollient or occlusive is a moisturizer. These are components of moisturizers, but occlusives, humectant and emollients are available in other products too like shampoos, cleansers, etc. We do need such substances in our skincare products, but if you write about types of moisturizers then the types are more like gel moisturizers and cream moisturizers. I had to mention that since it's great to share knowledge, but we have to remember that people will copy this knowledge no matter if it's right or wrong
