I'm not an MA but I'm a Beauty Adviser at a Walgreen's store in their beauty department. When I first started the job, I always tried to put a lot of effort in being made up everytime I was there to look nice. Now, I could honestly care less what I look like when I'm there. I show up completely naked face and looking like a hot mess lol. If you seen me at work you would probably think to yourself that this girl has absolutely no knowledge about makeup or anything beauty related. I've noticed that many of my other beauty advisers don't wear much makeup either or keep it really simple and natural, and I don't want my makeup to seem OTT compared to theirs. Plus I'm too tired and in a hurry to get ready to go to work to have time to whip out my kit.
When I actually look decent, I get a few customers who come in and ask what I use makeup and skincare wise. Which leaves me on the spot cause I don't use anything drugstore beauty products besides mascara, hair care, and chapstick. Of course, I'll show the customer to drugstore brand items that are similar to the MAC or Sephora products I use. I feel like I'm sort of lying to them when I'm not completely honest about which products I use. Cause when I tell them that "I use a product similar to this...." they'll mistakenly think that I actually DO use that product when I don't. I'll only rarely tell the customer secretly what I actually use cause I don't want to get in trouble. I've ran into a few MAC users there too and when I'm bare faced they're very surprised that I use MAC let alone know about it lol.
As for working for an actual high end cosmetic retailer or any freelancing work, then I would definitely be slapping the makeup on everyday I'm working. Because I agree that when you have a job like that it's important to advertise your services as best as you can. You have to be able to clearly demonstrate your skills on yourself in order to attract clients. Like everyone else is saying would you want someone who looks plain or has awful makeup on to do yours? I sure wouldn't. But this job I have now really in my opinion isn't really all that makeup related besides working in that department (which all really is just helping customers, ringing them up, stocking and cleaning) I don't really care what I look like since I don't get the opportunity to really even use any of my makeup skills for the job.
