Hi everyone! I'm studying my nvq level 3 make-up artistry and have come across this question and cannot find the answer anywhere. Can any help me please?

State 4 stages of carrying out a sensitivity test?

We aren't going to do your work for you. We will however help you.

What do you think some of the stages are?

You should know this, your lecturers should have told you or it will be in your books.

Does it mean a skin sensitivity test for make up or other treatments?
