    I’m a medical student who wants to specialise in dermatology.However, not much is taught when it comes to making skincare.
    I have some questions about formulating an acne cream ( or oily-skin cream)

    1) What should be the ratio between oil and water phase for oily skin? Is there benefit of using plant oils or liquid paraffin.

    2) What is the best solubilizer for salicylic acid in such a cream.Ethanol isn’t desirable , what about propylene glycol?
    3) What other active ingredients could improve the formule? I was thinking of adding citric acid and lactic acid.

    Thanks in advance

    You need to find a starting formula as the answer to most of those questions is…it depends.

    See this discussion for more information about formulating with Salicylic Acid

    IF you are making an emulsion (water and oil phases) it will most likely go in so don’t worry too much.  You can use propylene glycol or octyldodecanol if you want to
