Rubbing lemon on your face can have both positive and negative effects, depending on your skin type and the way it is used.
On the positive side, lemon is a natural astringent and contains vitamin C, which can help brighten and even out your skin tone. It also has antibacterial properties that can help reduce acne and breakouts.
However, lemon juice is also highly acidic, which can irritate and dry out your skin, particularly if you have sensitive or dry skin. It can cause redness, inflammation, and even chemical burns if used incorrectly or in high concentrations.
If you want to use lemon juice on your face, it is recommended that you dilute it with water or mix it with a gentle cleanser or moisturizer. You should also avoid using it on open wounds, cuts, or sunburned skin, as it can cause further irritation.
It's also important to do a patch test on a small area of skin before applying it all over your face to ensure that you don't have an adverse reaction.
