Kiwi for Skin: Benefits, Myths and How to Use It

Eating kiwi is good for your skin. One green kiwi gives you most of a day's vitamin C, which your skin uses to make collagen. Putting kiwi on your face is less useful. The vitamin C in fresh fruit breaks down quickly, the dose is unknown, and kiwi contains an enzyme that commonly causes allergies. Eat the fruit, and use a formulated product on your skin.

What is in kiwi that matters for skin?

Kiwi is one of the richest common fruits for vitamin C. Green kiwi has roughly 75–90 mg per 100 g, and gold kiwi often has more than 150 mg. One medium green kiwi gets you close to the 80 mg a day that adults need, according to Indian guidelines.

Kiwi also contains:

• Vitamin E, mostly in the small black seeds
• Carotenoids and polyphenols, which act as antioxidants
• Fibre, which slows the rise in blood sugar
• Actinidin, a protein-digesting enzyme similar to papain in papaya. Actinidin is also kiwi's main allergen.

Is eating kiwi good for your skin?

Yes, eating kiwi is good for your skin. Your skin uses vitamin C to build collagen and to protect itself from free radicals made by sun and pollution. Studies have found that skin vitamin C levels go up and down with blood levels. People who eat more fruit and vegetables rich in vitamin C have more of it in their skin.

Research on kiwi in particular has shown that adding two kiwis a day quickly raises vitamin C levels in the blood. That's a real, if indirect, benefit. If you were low on vitamin C, your skin's own collagen-building work gets the support it needs. Kiwi won't lighten your natural skin tone, and one fruit won't fade dark spots. Our guide to foods for glowing skin explains how kiwi fits with amla, guava and citrus.

Kiwi also has a fairly low glycaemic index compared with many tropical fruits, so it works well for anyone watching sugar for acne reasons.

Can you apply kiwi on your face?

You can, but it isn't a reliable way to get vitamin C into your skin. A kiwi face mask runs into three problems:

1. Stability. Vitamin C (ascorbic acid) breaks down quickly once fruit is cut and exposed to air and light. That's the same reason vitamin C serums turn brown. A mashed kiwi loses vitamin C every minute it sits out.
2. Penetration. To get through the skin, vitamin C needs a specific acidity and concentration, usually 10–20% L-ascorbic acid at a low pH. Fruit pulp is mostly water and fibre, and its dose is unknown and much lower.
3. Allergy. Actinidin is a common food allergen. Applying it to the face can cause itching, redness or swelling, especially in people with a latex allergy. Kiwi, banana, avocado and papaya are all part of the latex-fruit allergy group.

A kiwi mask can leave skin feeling fresh, because the fruit acids and enzyme loosen dead skin cells a little. That feeling doesn't last, and it doesn't show the mask is doing anything for pigmentation.

If you still want to try a kiwi mask, how do you do it safely?

• Patch test a little mashed kiwi on your inner forearm for 20 minutes. Our patch test guide explains how.
• Skip it completely if you're allergic to kiwi, latex, banana or avocado, or if your mouth itches when you eat kiwi.
• Use only fresh, ripe fruit. Mash it and apply it right away.
• Leave it on for no more than 10 minutes, then rinse with cool water.
• Don't use it on broken skin, active acne, or right after waxing or exfoliating.
• Once a week is enough.

Mixing kiwi with lemon juice or baking soda is a common idea online. Don't do it. Both can irritate the skin barrier and may leave dark marks on Indian skin.

Who should be careful with kiwi?

Most people can eat kiwi safely, but some people should be cautious, both when eating it and when putting it on their skin:

• People with oral allergy symptoms. If eating kiwi makes your lips, tongue or throat tingle or itch, that's an allergic reaction. Don't put kiwi on your face.
• People with a latex allergy. Kiwi shares proteins with latex. Reactions can range from mild itching to more serious swelling.
• People with eczema or a weakened skin barrier. Fruit acids and enzymes can sting and cause a flare.

If kiwi causes swelling of the lips or face, or any trouble breathing, get medical help right away.

Kiwi vs other fruits for skin

Kiwi belongs with other fruits that are better eaten than applied. Papaya has a similar enzyme. Tomato brings lycopene, carrot brings beta-carotene, and pomegranate brings polyphenols. Each helps the most as part of a varied diet. On the skin, you'll get much more from correctly dosed actives, daily sunscreen and steady cleansing.

Frequently asked questions

Does kiwi lighten skin?

No. Kiwi doesn't change your natural skin tone. Eating it supports overall skin health, and a regular routine with sunscreen helps even out tan and dullness.

How many kiwis should I eat for skin?

One or two a day as part of a balanced diet is plenty. More won't do more, because your body can only use so much vitamin C at once.

Is kiwi good for acne?

Kiwi is a fairly low-sugar fruit and a good part of an acne-friendly diet. Putting it on active pimples isn't recommended because of the irritation risk.

Can I apply kiwi on my face every day?

No. Daily fruit-acid and enzyme exposure can irritate your skin. Keep it to once a week at most.

Green or gold kiwi, which is better?

Gold kiwi usually has more vitamin C. Green kiwi has slightly more fibre. Both are good choices.

Can kiwi remove dark spots?

There's no evidence that it can. Dark spots respond to sunscreen and to actives like niacinamide over 8–12 weeks.
