Hello. I am currently studying cosmetology. I want to change my profession. What cosmetics can you recommend?

Where do you most often buy dermal fillers, aesthetic medical products and other medical products? For a long time, has become a reliable partner for me, which knows everything about modern products, so they can help customers find what they expect on the market and are most satisfied with cooperation with them. Perhaps you also have trusted suppliers, please share! I think it will be relevant for many workers in the beauty industry!
