I ended up learning how to do this and it worked well. Definitely practice first somewhere like a patch of your leg, upper lip, big toe, anywhere it doesn’t really matter about precision.

It’s much quicker than tweezing and can take off more than you intend so go slowly with short strokes and be very careful around arches. (I did my upper arches and between my eyebrows but left the bottom arches for when I get more confident.)

Do not do this for the first time before an important event!

I didn’t use any lotion but it still worked.

If your skin is sensitive it can get red bumps in the follicles afterwards. Keep everything as clean as possible during and after and perhaps use some Savlon.
