Do you think the procedure that I'm doing now is effective? Because I use loofah in scrubing my knees and elbows every time I put lemon juice on it and after 15 minutes. I wash it with warm water and scrub it with loofah and wash it again with warm water.

Or should I just let the lemon juice get dry on my skin until the next morning and when I take a bath I will not scrub it?

Its kind a confusing for me if I'm going to use a loofah for scrubing or not. Because what I know is scrubing makes skin darker.

You should just scrub very gently. I use a pumice stone, but I think the loofah isn't that different. I usually leave the lemon juice on then put lotion over it. I'm not sure if washing it off is effective, but if it doesn't work you can just try keeping it on.

Does lemon juice alone lighten the skin
