I will be happy to help you with this.
I have experience with these type of field since I supported the internationalization process of a company that was on the skincare sector and needed to position her product online in this foreign market.
There are different companies you can use to launch these products; Shopify, Big Commerce, Volusion, etc... That should not be your main concern, I think you should know that if you want to introduce and position your new product what you need to do in terms of marketing activities are on-live testing, soft launching activities, real testimonies on video, post and mention your governamental permits. Pay extra to use their logos and make sure you have a professional-looking website.
If I can help you with anything else, let me know!
