How to become a successful beauty YouTuber?

successful beauty guru?
Basically I recently started my beauty videos but because of exams, I couldn't be very active on YouTube.

Last week, I started posting videos again and I went from 146 subcribers to 249:)

I would like to know, what kind of videos do people like to watch on beauty channels? And which videos are the most popular?

My last video was a DIY which is what I've noticed a lot in my subscription box from popular youtubers lately.

What other videos do you recommend doing to get more views and subcribers?

Also i'm thinking of getting a Nikon dslr or a Canon possibly.

Thank you:)
