Smoothes and decreases irritation , not a bump in sight!!
Scent: For Sensitive Skin, Size: 2 Fl Oz (Pack of 1)
I wish that I had found this product sooner-it’s amazing! I would always get bumps and irritation after dermaplaning-this is a complete game changer. You will not be disappointed-just make sure that if you have sensitive skin to get the right one, as there are different options.

Smells weird
Scent: For Oily Skin, Size: 2 Fl Oz (Pack of 1)
This works fine for what it does, but it definitely has a strong odor that I find very unpleasant.

This is for people who have dryer skin
Scent: Dermaplane Kit, Size: 2 Fl Oz (Pack of 1)
I did not realize that they made oil for dermaplaning. I've tried dermoplaning myself and on my dry skin it was very sensitive and it hurt. But this oil is amazing it's not too oily it soaks into your skin very well sometimes I put it on and don't even dermaplane. But to use it for the dermaplaning is wonderful. My skin turns out very nice and a soft and not sore and cut.
