Self-study: you can learn makeup artists and skills on some websites, or you can watch videos and practice slowly by yourself;
But for a long time, I didn't have the opportunity to practice my hands, and I wasn't professional enough.
Makeup shop apprentice: Work in the shop and then "steal the teacher" to study, because the shop is generally reluctant to bring new people, all it needs is an assistant. If they need a makeup artist, they can recruit directly, and they don't need to spend manpower and financial resources to train makeup artists. There is no systematic teaching in the shop, which wastes a lot of time.
Go to makeup training school: choose a professional training school and start from scratch when you get to school. Schools can connect students with each other, and there is no problem in practice. Technically, as long as the teacher is responsible, patient and skilled, you can learn to make up quickly.
