Two or three days ago, I added fresh lemon juice (from half of a lemon) into a big bowl of water and used it to wash my face. It was supposed to whiten my complexion. But instead, tiny little bumps have appeared on my entire face and a little bit of neck area. They're not reddish and are not very visible but when I touch my face I know that they've made my face rather rough. I feel itchy on the eyebrows and near my ears.
I'm not sure if this is due to lemon juice.
I want to ged rid of the itchiness and the bumps so that my face can be smooth and back to normal again.
What shall I do?
