Great quality! So much more than the regular disposable tinkle razors!
Color: Silver
So much better and higher quality than the usual disposable tinkle razors. I gave all my other tinkle razors away and will stick with this one!

New Fave Dermaplane
Color: Silver
Love how heavy duty this product is and that the razors are replaceable. So much better than the cheap plastic dermaplane razors.

Smoothest Dermaplane Session EVER!
Scent: For Sensitive Skin, Size: 2 Fl Oz (Pack of 1)
This stuff is MIRACULOUS! I also struggle with dermaplanning at home and much prefer to have a professional do it, but that’s too costly for me to do as often as I’d like. I won’t say using this made the results as good as a professional but it wasn’t far off! It literally transformed the entire at home experience! I also end up with my skin feeling dry and irritated and almost bumpy and I feel like I never get a close or smooth result and it takes forever. This cut the process down by about half the time, I had zero redness or irritation afterwards, my skin was silky smooth, and I had zero rough spots. It took a very small amount of product and I never had to add any extra. I left it on afterwards until I got in the shower because it felt so soothing on my face. I have experienced no breakouts after using this and I honestly feel like it helped repair some areas that always feel a bit rough on my face. I can’t recommend this enough! For the record, I have tried dermaplanning with a variety of regular face oils and those worked just as well as using nothing. So I was really doubtful that just because this was marketed for dermaplanning it would make a big difference. But it honestly made a massive difference! I really appreciate that I was able to purchase a smaller bottle at a reasonable price to try. Even though the small bottle will probably last forever I’ll definitely be ordering the big size when I’m out. I will forever purchase this stuff!

Apply the Oil first prior to using your dermaplane. I used “for sensitive skin.”
Scent: For Sensitive Skin, Size: 2 Fl Oz (Pack of 1)
I only had to apply a small amount to my facial areas where I use my dermaplane. It was easy to,apply, wasn’t messy, didn’t irritate my skin or cause any reaction. It worked great with my dermaplane and soothed my skin.
