Which is better to do, beauty medical devices or medical devices and health products for the elderly?

Although medical devices are profiteering products, their prospects are also very worrying. It's a little late now, and the market is basically saturated. The most important thing is not that the market is saturated. Even if it sells well, it needs to be worn out. Needless to say, you used to do beauty, which was actually a kind of sales. The problem is that there is an essential difference between medical equipment and beauty. The beauty lies in that after you say a few words, Ms. Amy may bring you many customers in the future, and the medical sector is basically facing the elderly. Nowadays, old people are very smart, unlike when we first started marketing, telling them that all old people should be treasures. Now you say your old man has his own ideas. Of course, this is just my own opinion, let alone a hero. Seeing your question, I just came to answer and express my opinion. Good luck.
