Although I regret it, I can't get a refund. In a plastic surgery hospital like the hospital, as long as you spend money and do the corresponding services, you can't get a refund. It's the same everywhere. For the simplest example, you have finished eating in the restaurant. After eating and drinking enough, I feel that the taste is not delicious. Can I get a refund? In the same way, you paid the money and enjoyed the corresponding service. Although I regret it, I can't refund my money. Whether it is effective or not depends on your personal situation and physique. Well, what's more, whether you can get the sun after finishing it will also be affected to some extent. Anyway, a refund is basically impossible. I'll give it to you once at most.
