I may be able to help you with this question, because I have acne on my face, and I have worked in the catering industry for several years, so I still have some experience.
The service of the restaurant is more important to gfd, that is to say, it should look comfortable! So if you have acne on your face, you can put on a light makeup at work, which will have a certain effect, but remember to remove makeup after work!
acne on your face is because your skin is oily, so you should pay more attention to protection at ordinary times, such as cleaning your face before going to bed! Usually eat a lot of spicy food, don't drink, don't smoke!
it is very important to ensure your sleep, and you can't sleep upside down, which is the biggest enemy of your skin! I hope I can help you, wish you a smooth interview, and hope your acne will leave you as soon as possible. . . . . .
