Mustard Oil for Skin and Face: Benefits and How to Use

Mustard oil (sarson ka tel) has been rubbed into Indian skin for generations — the winter malish, the bottle of oil by the bathwater, the ubtan before a wedding. As a skincare oil it earns its place honestly. It is rich in monounsaturated fat (MUFA) and also carries omega-3 ALA, omega-6 linoleic acid and some naturally occurring vitamin E, so on the surface of the skin it behaves as an occlusive, softening oil that helps slow water loss and leaves skin feeling supple. Cold-pressed kachi ghani oil keeps its pungent aroma and the seed's natural compounds because it is crushed cold — never bleached or deodorised. Traditionally it is used as a body oil, for massage, and blended with turmeric or besan; some laboratory research also points to antimicrobial and antifungal activity. It is not a medicine and it is not a sunscreen. This is general information, not medical advice — patch-test first, and see a dermatologist for any real skin concern.

What are the benefits of mustard oil for skin?

The honest, non-hyped answer: mustard oil is a good emollient. Because it is mostly monounsaturated fat (with omega-3 ALA, omega-6 linoleic acid and a little vitamin E), a thin layer sits on the skin, softens it and slows the moisture that dry, wintery air pulls out. That is the same reason grandmothers reach for it for a cold-weather malish. Everything beyond "it moisturises and it's a traditional massage oil" should be read as tradition or early research, not proven treatment.

• Moisturising: a natural emollient that helps skin hold on to water — useful for dry or flaky skin, especially in winter.
• Massage (malish): warms easily, spreads well and has long been the oil of choice for full-body and scalp massage across North and East India.
• Nutrient profile: rich in MUFA, plus omega-3 and omega-6 fatty acids and some vitamin E, per general oil-composition data such as USDA FoodData Central.
• Traditional grooming: a base for ubtan and besan-and-haldi pastes used before weddings and festivals.
• Aroma and warmth: the sharp kachi-ghani smell is exactly what many people associate with a "proper" oil massage.

Can I apply mustard oil on my face?

Yes, you can apply mustard oil on your face — but treat it like any rich facial oil, not a miracle. It is on the heavier, more occlusive side, so it suits normal-to-dry skin better than oily or acne-prone skin, where a thick oil can feel greasy or clog pores. Always do a patch test first: dab a little on the inside of your forearm and wait 24 hours, because mustard's pungent compounds can irritate sensitive skin. Use a small amount, warm it between your palms, press it in, and cleanse it off properly afterwards rather than sleeping in a heavy layer.

A note on regulation that surprises people: in India, mustard oil is a permitted, everyday edible oil regulated by the FSSAI. In the United States, however, the U.S. FDA does not authorise mustard oil as a cooking oil, and imported mustard oil there must be labelled "for external use only" because of its natural erucic-acid content. So the very product some countries restrict at the stove is, ironically, sold abroad specifically for skin and massage use. On Indian skin, applied topically, it is a long-standing traditional practice.

Is mustard oil antifungal or antibacterial?

There is some evidence that it can be. Mustard oil contains allyl isothiocyanate, the compound behind its pungency, and laboratory studies indexed on databases like PubMed have reported antimicrobial and antifungal activity for mustard oil and its constituents. That is genuinely interesting — but a petri-dish result is not the same as a proven skin treatment. Mustard oil is not a cure for ringworm, athlete's foot, acne or any fungal or bacterial infection, and it should never replace an antifungal or antibiotic your doctor prescribes. If you have a persistent rash, itch or infection, see a dermatologist rather than relying on a home oil.

How to use mustard oil for skin

The simplest way to use mustard oil on skin is as a body oil: warm a little in your palms and massage it in on slightly damp skin after a bath so it seals in moisture. Below are the ways it is most commonly used at home. Start with a patch test, use small amounts, and rinse off pastes gently.

• As a body moisturiser: a light layer post-bath on arms, legs and elbows to combat dry, rough skin.
• As a face moisturiser: only a couple of drops, pressed in at night — best for dry skin, and better avoided if you are acne-prone.
• With turmeric (haldi): a pinch of turmeric stirred into a little mustard oil is a classic gharelu paste; use sparingly, as turmeric can temporarily stain lighter skin yellow.
• In ubtan: mixed with besan (gram flour) and a little turmeric or curd into a scrub-paste for the traditional pre-wedding glow ritual.
• For massage (malish): the everyday full-body or scalp oil, often warmed slightly for winter.
• On cracked heels, elbows and dry lips: a dab worked into thick, rough patches at bedtime.

Read the label, not the legend: mustard oil is a fine, traditional moisturiser — it is not a face treatment, a fungal cure, or sun protection.

What about mustard oil in the navel (nabhi / belly button)?

Putting a few drops of mustard oil in the navel — nabhi, or the belly button — is a traditional practice, part of a wider folk idea that the navel is a special point for applying oils. Around it you will hear many nabhi me mustard oil benefits claimed: softer skin, better digestion, glowing skin, relief from dryness. It is fair to describe this as a long-standing custom and as a pleasant, warming ritual. It is not fair to promise health results. There is no reliable clinical evidence that oil in the belly button treats or prevents any medical condition, and applying it to the navel is not meaningfully different from applying it to any other patch of skin. Enjoy it as tradition, keep expectations grounded, and don't use it in place of real care for any health issue.

Does mustard oil darken skin — and can it work as a sunscreen?

Two popular beliefs, both worth correcting. First, there is no good evidence that mustard oil darkens skin — in fact it appears in ubtan recipes precisely because people associate it with a softer, brighter look; any yellow tint you notice usually comes from turmeric added to it, not the oil. Second, and more importantly: mustard oil is not a sunscreen. A thin film of oil offers negligible, unreliable protection against ultraviolet rays and can even make some skin feel warmer in the sun. Health authorities such as the WHO advise proper sun protection — a broad-spectrum SPF, shade and covering up — not cooking oil. Never rely on mustard oil to protect you from the sun.

Which oil is best for your skin?

There is no single "best" oil — it depends on your skin. Mustard oil suits normal-to-dry skin and people who love a warming massage. If your skin is oily or acne-prone, lighter oils tend to feel better, and if you have very reactive or eczema-prone skin, get a dermatologist's guidance before layering any strong-smelling oil on. What you can control is quality: choose cold-pressed kachi ghani mustard oil that is crushed cold and unrefined, so the colour, aroma and the seed's natural compounds are intact rather than bleached and deodorised out.

A safety note, especially for babies: newborn skin is delicate, and some medical guidance cautions against using mustard oil for infant massage because it may irritate the skin barrier. If you are considering any oil for a baby, please speak to your pediatrician first. More generally, this article is general information and not medical advice — patch-test before you start, stop if you see redness, stinging or breakouts, and consult a qualified doctor or dermatologist for any ongoing skin concern.
