Facial Hair

Fine dark hairs on the face can actually make you appear a little older than you really are.
My recommendation would be to eliminate any hair making its appearance on the upper lip and keep the eyebrows neatly shaped.
For any chemical applications such as facial hair bleach or depilatories like Nair or Veet be sure to do a patch test as directed beforehand to prevent redness, rashes and swelling from occurring on the face.
I'm not a big advocate for chemical depilatories. The use of facial hair bleach, (Jolen or Sally Hansen for sensitive skin types are good brands to try), is a great way to lighten "peach fuzz" around the lips, on the cheeks, chin and forehead. Post-bleaching leaves the skin a bit pink but once that subsides both the skin and hair have a nice lightened and brightened appearance.
Waxing or threading are quicker ways to temporarily eliminate facial hair than tweezing. Both are minimally uncomfortable and may leave you a bit pink for up to a few hours, (you can conceal this with a light application of mineral make-up). If you are prone to breakouts post-waxing or threading I would recommend requesting that your esthetician use something to act as a barrier between the skin and wax, (like powder or numbing spray), and finish using the high frequency machine, (as long as there are no contraindications), to help minimize both redness and acne causing bacteria.
If you are super sensitive or can't tolerate the discomfort that accompanies the hair removal methods listed above then I would recommend a handy little tool by Finishing Touch. This pen-like razor quickly and painlessly shaves the hair and is a great fix for those last minute emergencies. And, unless the hair is thick and coarse to begin with, it will not cause the hair to grow back stubbly.
