I eventually realized I didn't have to accept my dark underarms. The darkness came from shaving because of my dark coarse hair. Even shaving once makes them dark!
I have been using the Gigi wax warmer for years. I honestly prefer the Gigi Brazilian Body Hard Wax. It's easier to use than the wax with strips!
Lower the heat level to low after your wax warms up and melts to a thick consistency. If you don't you might burn yourself. Even at low I give it a few seconds on the stick before I apply it to my skin.
You need to allow it to harden at least 5-8 minutes. If you don't give it enough time it wont peel properly.
Peel it off against the direction of your hair growth. Do this slowly. If you didn't apply it evenly it may leave some areas you need to pinch off as I did here.
As you can see, this side was applied more evenly and peeled right off!
I added these clips without the ring light that can bring out harsh details. My dark underarms have lightened significantly just by not shaving. Browse all of the lightening tips from viewers in this IG post.
