Ok, so it's been more than 30 days since I started the Visibly Smooth Challenge.
My underarm hair was definitely changed. I can't really say whether the LOOK of my hair decreased, but I can certainly say that the FEEL of it did.
I can also say that the Dove Visibly Smooth products made shaving a lot easier - there was no need to go back and forth over the area a couple times - once was enough.
I still found it hard to remember to apply it nightly - which it why I went over the 30 day trial period - I wanted to make sure that I did indeed, use it for 30 days.
So, would I recommend it to a friend?
Sure, why not. It's not a miracle product, but it helps to ease shaving, so I would hope that would lead to less razorburn and other irritations. I fairly happy with the product, but I'm not sure that I would continue using it - only because I can get quite lazy and forgetful with daily application.
