Tanning drops

Has anyone used tanning drops? If so how would recommend them? Which brand did you use? Was it a natural looking tan? All the things all the details please if you don’t mind 🙏🏼
I have the most dull skin and it only looks - well not good but better with a tan but also just went through a skin cancer scare, I know too much sun exposure is bad for skin and ages it so I’m trying to explore other routes, I’m super down at the moment and my appearance is a big contributor to that. Any recommendations would be greatly appreciated, thank you so much in advance 🙏🏼 💙
