Is Lime Water Good for Your Skin?

Partly: lime water may support normal skin hydration if it helps you drink enough fluid, but it has not been shown to clear skin.

Can lime water help clear skin?

Lime water can be a useful way to stay hydrated if you enjoy its taste. Adequate hydration supports normal skin function, but adding lime does not make water a proven treatment for acne, dark spots or other skin concerns.

Clear skin depends on more than what you drink. Hormones, genetics, skin care products and medical conditions can all play a role. If you are comparing the best drinks for clear skin, focus on drinks that help you meet your fluid needs rather than expecting one ingredient to change your complexion.

How might lime water support skin?

Water helps the body maintain normal fluid balance, including in the skin. If you are not drinking enough, getting adequate fluids may help with dryness related to dehydration. It will not necessarily resolve dryness caused by eczema, cold weather or other factors.

Lime also contains vitamin C, which the body needs to make collagen, a protein that helps give skin structure. But the amount of vitamin C that transfers into water from lime slices is uncertain. You should not assume a glass of lime water provides the same nutrients as eating the whole lime.

Plain water supports hydration too, and there is no evidence that lime water is better for skin. Drink an amount that meets your needs rather than forcing large quantities in the hope of seeing faster results.

What does the evidence say about lime water and skin?

The available evidence is limited. No clinical trials of drinking lime water for clear skin are included in the evidence reviewed here, so its effect on acne, pigmentation or other skin outcomes has not been established.

The lime-related reports available address a different issue: skin exposure rather than drinking. A 2019 case report describes a skin reaction after lime contact followed by sunlight, and a 2024 article on lime dermatitis discusses how plant compounds can make skin sensitive to light. Neither study shows that drinking lime water improves skin.

How should you make and drink lime water?

For a simple, unsweetened infusion, use:

• 1 lime, about 100 g (1 whole fruit)
• 1 liter water (about 4¼ cups)

1. Wash the lime under running water and slice it with a clean knife.
2. Add the slices and water to a clean pitcher. Cover and refrigerate for 2–4 hours.
3. Remove the slices by 4 hours to limit bitterness from the peel and pith.
4. Keep the lime water refrigerated and drink it within 24 hours for best flavor. Discard it after 2–3 days, or sooner if it becomes cloudy, slimy or sour-smelling.

Do not leave infused water at room temperature for more than a few hours. Steeping adds flavor without the same amount of fruit material as squeezing or blending; the drink’s exact nutrient content is not established here.

You can drink lime water with a meal if you enjoy it. There is no established best time of day or required number of glasses for skin benefits, and adding sugar is not necessary.

Who should be careful with lime water?

Lime is acidic and frequent exposure can contribute to tooth enamel erosion. Avoid sipping it continuously throughout the day; drinking it with a meal and rinsing your mouth with plain water afterward can reduce the time acid stays on your teeth. If you have sensitive teeth or enamel concerns, ask your dentist for advice.

Lime may also aggravate reflux or mouth irritation in some people. Choose plain water if it causes discomfort. If you have kidney disease, heart failure or another condition for which you have been advised to limit fluids, follow your clinician’s guidance rather than increasing your intake for skin benefits.

Do not apply lime juice or lime water to your skin as a skin treatment. Lime on the skin followed by sunlight can cause a painful reaction called phytophotodermatitis, sometimes with blisters. If lime splashes onto your skin, wash the area with soap and water and keep it out of the sun.

Seek prompt medical care for severe blistering or possible signs of infection, such as spreading redness or fever. See a clinician or dermatologist for persistent acne, a rash, painful spots or scarring; lime water is not a substitute for an assessment.
