I used to go a little bit "tweezer happy" on my brows...causing me to get ingrown hairs and acne around my eyes. Since last October, I have been growing them out. Things look a lot more natural now, it is easier to maintain, and I didn't have any problems growing the hair back. I just used eyebrow pencil to fill in the newer spots so that they didn't look messy!
BTW, I use Differin Cream now, but I used to use Duac. If you use Duac or anything with BP in it, be careful putting it on hair/eyebrows because it can kinda bleach it out at the tips!
