This is such a good post! Simple and very informative, good job! ^_^
I think I would have liked to see some sample ingredients for each type of "moisturizer". When I looked at my bottle of lotion, I couldn't tell what type of moisturizer (or combination of moisturizers) I was using. Otherwise - very nice and informative.
Love your illustrated posts! But I am also curious to know what ingredients are in each of the 3 categories you mention.
Occlusive agents increase moisture levels in skin by providing a physical barrier to epidermal water loss. Ingredients with occlusive properties include petrolatum, waxes, oils and silicones. Some occlusive agents like petrolatum can leave a heavy feeling on skin; thus they often are combined with other ingredients like emollients to improve consumer appeal.（http://www.cosmeticsandtoiletries.com/research/chemistry/57787362.html）
