It is safe to leave lemon juice on your face for 15-20 minutes. However, if you experience any skin discomfort, such as burning, stinging, or redness, wash it off immediately.
Remember, everyone's skin is different, and what works for one person might not work for another. It's always a good idea to do a patch test on a small area of your skin before applying lemon juice to your entire face. This will help you determine if you have any sensitivities to lemon juice.
