Hi C., I can relate! At some point before having kids I too noticed a darkening "moustache" over my lip. I've had no formal training, but am happy to share some things that have worked for me:
- Bleaching the hair. It's not stubbly, but rather soft peach-fuzz hair that I hadn't noticed was darker. This helped a lot - just a Sally Hansen Bleach Kit available anywhere.
- Neutrogena sunscreen with "Helioplex" prevented further darkening of the skin. Being an active mom in MT, staying out of the sun just wasn't an option!
- Microdermabrasion treatments to gently slough away old (and dark) skin. There are good at-home treatments, but my favorite exfoliator is plain old baking soda. Mix with water to form a paste, gently rub onto your skin in an upward pattern (avoid tugging & pulling skin downward) & rinse. Softest skin ever! Great for dry, summer skin as well.
- If all else fais, find an estetitian (sp?) in your area that also has a clinical background. I found a great lady that also was a nurse & had practiced in a Houston dermatologist's office. While very relaxing, her facial treatments were scientifically (sp?) based rather than simply enjoyable. She also suggested that once the sun's rays weren't so damaging (after summer) she had a treatment to try. But with the bleaching, Heliplex & baking soda I haven't needed to go back.
Hope that helps and you find some releif & lightening. If all else fails, a good estetician can kick-start a lightening for you.
