If you're not already working as a makeup artist, beauty therapist, model, photographer or similar... then getting any relevant qualifications would generally be part of the process before you can get involved in the profession.

It doesn't state that you have to have them, but do you meet any other professional ID requirements that you can use instead?

are you intending to become a makeup artist? if so, then yes, it's a good idea to do a course. if you just want this card for the discount and don't intend to ever use the qualification, then it's probably not worth the cost and effort of taking the course.
