A few comments on my blog bud Afrobella's blog caught my attention:
As for the darkening seen on the necks, knees and elbows of black folks, isn’t that just brown skin. The only black people I’ve ever seen who didn’t have a little darkening on there knees or necks were those people who are Alex Wek dark and those of majority mixed ancestry. I don’t know how many young women I seen scrub the backs of their necks and knees with rubbing alcohol and Clorox bleach in an effort to mix there skin tone. I don’t think it can be fixed.
Bite your tongue, girlfriend! Of course it can be fixed! And rubbing alcohol and Clorox bleach? Are people still doing that in this day and age?
I've got two words for you: exfoliation and sunscreen. Skin sheds and regenerates anyway, so you don't have the same skin you had on your body last year. Exfoliation speeds up that process and when you add sunscreen, especially in the summertime when they are exposed more, voila! Your elbows and knees are the same color as the rest of your body. There is no need to use any type of skin lightener to get the effect, although you can if you'd like to. The secret weapon here, in my non-medical opinion based on my own experience, is sunscreen which helps prevent most re-darkening. That's all any celebrity does too - look at Naomi Campbell. That picture is from New York magazine and, trust me on this one, they don't bother airbrushing darkened elbows.
So, give it a try and let me know what you think. Happy scrubbing!
