If you’re looking for a way to lighten your skin naturally, you’ve probably stumbled upon the lemon juice lightening method. While lemons do contain some key vitamins, putting lemon juice on your skin isn’t the best (or safest) way to lighten dark marks. We’ve answered some of your common questions about skin lightening so you can keep your skin healthy while doing it.

Question 1 of 8:

Can you lighten your skin with lemon juice?

Download Article

Some people believe you can! While there are some natural health sites that recommend using lemon juice for skin lightening, scientists recommend using actual skin products. If you’d like to try using lemon juice, however, you can squeeze the juice from a lemon into a bowl and add equal parts water to it. Dip a cotton ball into the mixture and gently dab lemon juice onto any dark spots on your face. Let the lemon juice sit for 20 minutes, then rinse your face with cool water.^{[1]

- You can do this a few times per week to fade dark spots on your skin.
- If you’re trying to fade dark marks on your chest or back, pour your mixture into a spray bottle and spritz it all over your dark spots. Let it sit for 20 minutes, then wipe the solution off with a wet washcloth.
- It’s incredibly important to rinse the lemon juice off your skin before going outside. Leaving lemon juice on your skin when you go out into the sun can lead to blisters and burns.

Question 2 of 8:

Is lemon juice safe for my skin?

Download Article

Yes, as long as you make sure not to go out into the sun. Lemon peels often contain chemicals called furanocoumarins and psoralens. While these chemicals are fine on your skin when you’re in the shade, if you go outside into the sun, they can cause redness, irritation, swelling, and huge blisters. Most products that use lemon juice filter these chemicals out, which is why it’s okay to use lotions or fragrances with citrus in them. However, straight lemon juice isn’t filtered, and it can be dangerous to leave on your skin, even if you dilute it with water.
- If you’re worried about your reaction to lemon juice, try doing a patch test first. Rub a bit of undiluted lemon juice onto the inside of your elbow. If your skin is okay after 24 hours, it’s probably fine to use lemon juice on your face. If your elbow starts stinging or burning, rinse the lemon juice off immediately and don’t put it anywhere else on your body.^{[2]

If you deal with oily skin, grind 2 tbsp (28 g) of old-fashioned oats into a fine powder. Mix the oat flour with 1 US tbsp (15 mL) of fresh lemon juice and 2 teaspoons (9.9 mL) of honey. Dab it on your skin with clean fingers, then let it sit for 15 minutes. Wipe the mask off with a warm, wet washcloth when you’re done.^{[3]

Question 4 of 8:

Why do so many sites recommend using lemon juice?

Download Article

There are lots of skin products that use citric acid in them, including ones with lemon juice. However, these products use filtered lemon juice, so they aren’t dangerous to put on your skin, and they won’t cause you to blister in the sun. Unfiltered lemon juice may lighten your skin, but it can also seriously harm you, so it isn’t worth the risk. There is no way to filter or dilute lemon juice at home to make it safe for your skin.^{[5]

Question 5 of 8:

Are skin products containing lemon juice safe?

Download Article

Yes, because they’re filtered. Lemon juice in lotions and creams is safe to put on your skin, and they probably won’t cause irritation. Products with citric acid in them can help fade dark marks and discoloration, and they aren’t dangerous like unfiltered lemon juice is.^{[6]

- Most lemon juice products are used to tighten the skin and reduce the appearance of wrinkles.

Question 6 of 8:

How do you lighten your skin naturally?

Download Article

Skin lightening products infiltrate your skin and reduce the melanin that creates dark spots. Look for a product with 2% hydroquinone, azelaic acid, glycolic acid, kojic acid, retinoid, or vitamin C to make sure it’s effective.^{[7]

How long does it take to fade dark spots?

It can take anywhere from 6 to 12 months. If you’re using sunscreen and a dermatologist-approved lightening cream, you can expect to see results within a year or so. However, if your dark spots are really dark, it could take a couple of years.^{[10]

- Everyone’s skin is different, and yours might need more or less time to even out. If you have any questions, make an appointment with a dermatologist.

Question 8 of 8:

Are skin lightening products dangerous?

Download Article

Yes, if they contain mercury. A lot of skin lightening products are unregulated, and some even contain mercury. Mercury can damage your kidneys and your nerves, and you can even spread mercury poisoning to others through skin-to-skin contact. If your product contains calomel, cinnabaris, quicksilver, or Hydrargyri oxydum rubrum, that means it contains mercury, and you should stop using it right away.^{[11]

While this is something you can do (as it's generally not going to cause harm other than potentially drying the skin), it has no benefits, so it's really not a worthwhile activity. It can leave your skin feeling sticky, and the juice will end up on your pillowcase and sheets. Since it doesn't have a benefit, and can increase skin dryness, this seems like a lot of effort (putting it on and cleaning the bed linen) for no real returns. If you do leave it on, be sure it is thoroughly washed off before you head outside, to lessen any risk of reaction with sunlight on your skin.

Question

I'm black. If I do this process, can I become little white?

Community Answer

The lightening effect of natural substances like lemon is very mild. It will lighten your skin a little bit, but you will still be black. Drastically altering your skin tone requires harsh chemicals. And it is generally not worth it. It's best to try to accept yourself as you are and embrace your own natural beauty.

Question

Can I leave the lemon on over night?

Community Answer

Yes, but be sure to wash it off in the morning. Also, consider applying some moisturizer, such as cocoa butter, so that your skin won't dry up.
