Does adding an oil to a surfactant cleanser formula increase or decrease irritation potential?
We have all heard of the “oil cleansing method” and how “oils attract oils”. (Unless this actually untrue, then please correct me.)
If the above is true, then does adding an oil to a surfactant cleanser formula increase the cleansing ability of the formula, therefore potentially increasing the irritation potential for skin types that require very gentle cleansing activity?
Or does the oil act more as a buffer against the action of the surfactants on skin, or as a moisturizer, that would make the formula milder?
