I have been waiting to "unyellow" my nails. I'm going to continue to be secretive about why, but I want to show you why I prefer to buff versus other options, such as lemon juice, backing soda, peroxide, etc.
First let us take a look at the horror that is my yellow nail bed ... you might want to get a waste basket just in case you start to regurgitate at the sight.
Ewwww ... there are no words.
I personally love my square buffer that I showed here and here.
As I have discussed in previous posts, buffing should be done in moderation. If your nails are thin you may want to just skip it altogether or be very light handed and use a very high grit strength buffer.
Look at that ring finger!
My hubby said, "Oh look, now your nails don't look like you've been smoking for 20 years"
... jerk ... then I scratched him across the face with my newly stain-free nails.
