No Pari, I don't know of any miracle creams that can make u fair and nor do I reccomend that u use any cream that claims to make u fair. Just maintain u're skin keep is clean and clear of any blemishes and treat scars if u have any.
Just a reminder to all the girls:
NO cream can make u fair
NO pill can make u thin.
I've given a couple of remedies for brittle nails in this thread and hair-care tips as well, please go thru and check for the ones that wud work for you.
