Skin Care Assignment

[Glmcdonald]

Hey everyone, I'm in need of some help. I'm doing the skin care course and on assignment B4 on makeup formulas. I'm really confused as to what they are asking for the formulas. Are they talking about certain primers and foundations for particular skin types or are they wanting specific ingredients in each product that you need to use for that skin type? Help! I'm at a bit of a loss!
