Question: how many times a day should i put lemon juice on my face?
Answer: Lightening your skin with lemon juice will take a long time, so it's tempting to try to apply a mask or lemon juice every day. Try to stick to 3-4 applications every week. Lemon juice dries out the skin too much to apply every day. Lemon juice may help with acne, but talk to your doctor about its effectiveness.
