I'm the same way! I currently use a mix of drugstore and higher-end products, but I'm always open to trying new things.
Have you ever considered getting professional advice on your skincare routine? I recently discovered aesthetics schools, where you can learn about skincare and beauty from experts in the field. They offer courses on everything from nail technology to advanced esthetics, and some of their graduates even become licensed aestheticians who can give personalized recommendations on skincare routines.
If you're interested, I found this link for Northwest College's nail technology program: https://www.nwcollege.edu/programs/nail-technology. While it might not be exactly what you're looking for, it could be a good starting point for exploring other programs and options.
