Mustard Oil for Skin: Science-Backed Benefits and How to Use It
Cold pressed mustard oil is one of the most effective natural skin treatments available — not because of tradition alone, but because of its fatty acid profile, Vitamin E content, and antibacterial compounds. Here is what the science says and how to use it correctly.
Why Mustard Oil Works on Skin: The Biochemistry
The effectiveness of cold pressed mustard oil on skin comes from four distinct compounds:
1. Fatty Acid Profile (Mimics Skin's Natural Sebum)
Cold pressed mustard oil is approximately:
- 60% monounsaturated fatty acids (MUFA) — primarily erucic acid and oleic acid
- 21% polyunsaturated fatty acids (PUFA) — Omega-3 and Omega-6
- 7% saturated fatty acids
This profile closely resembles the skin's natural sebum. Oils whose fatty acid composition matches sebum absorb into the skin without leaving a heavy residue and without disrupting the skin's natural oil balance. This is why mustard oil feels different from coconut oil (high saturated fat, sits on the surface) or sunflower oil (high Omega-6, can disrupt the skin barrier over time).
2. Vitamin E (Tocopherols) — 15–20mg per 100ml
Vitamin E is the skin's primary fat-soluble antioxidant. It:
- Neutralises free radicals generated by UV exposure, pollution, and metabolic processes
- Protects cell membranes from oxidative damage
- Supports collagen synthesis by protecting the enzymes involved in collagen production
- Reduces UV-induced skin damage (not a sunscreen substitute, but a meaningful adjunct)
Cold pressed mustard oil contains 15–20mg of Vitamin E per 100ml — significantly more than refined mustard oil (5–8mg) because the high-heat refining process degrades tocopherols.
3. Allyl Isothiocyanate (AITC) — Antibacterial and Anti-inflammatory
AITC is the compound responsible for mustard oil's characteristic pungency. On skin, it provides:
- Antibacterial activity against Staphylococcus aureus and Propionibacterium acnes (the primary bacteria involved in acne)
- Antifungal activity against Candida and Malassezia species (responsible for fungal skin infections and dandruff)
- Anti-inflammatory activity via COX-2 inhibition — reduces redness, swelling, and irritation
AITC is present only in cold pressed mustard oil. Refined mustard oil loses it entirely during the high-heat extraction and deodorisation process.
4. Beta-Sitosterol — Anti-inflammatory and Barrier-Supportive
Beta-sitosterol is a plant sterol that reduces skin inflammation and supports the integrity of the skin barrier. It is used in pharmaceutical-grade skin creams for eczema and psoriasis. Cold pressed mustard oil contains it naturally.
Benefit 1: Deep Moisturisation for Dry Skin
Cold pressed mustard oil is one of the most effective natural moisturisers for severely dry skin — more effective than many commercial lotions for people with very dry or dehydrated skin.
Why it works: The MUFA content creates an occlusive layer on the skin surface that reduces transepidermal water loss (TEWL) — the evaporation of water through the skin. Reduced TEWL means skin stays hydrated for longer. The Omega-3 content also supports the skin barrier's lipid matrix, which is the primary structural defence against moisture loss.
How to use: Apply a small amount of cold pressed mustard oil to damp skin immediately after bathing — while the skin is still slightly wet. The oil seals in the moisture from the bath water. Massage in circular motions until absorbed. A little goes a long way — start with 3–4 drops for the face, a teaspoon for the body.
Best for: Dry skin, dehydrated skin, flaky skin, skin that feels tight after washing.
Benefit 2: Anti-Aging and Wrinkle Prevention
The Vitamin E and antioxidant content of cold pressed mustard oil makes it a meaningful anti-aging treatment — not in the sense of reversing existing wrinkles, but in slowing the oxidative processes that cause premature skin aging.
The mechanism: Skin aging is driven primarily by two processes: intrinsic aging (genetic, unavoidable) and extrinsic aging (UV exposure, pollution, oxidative stress — largely preventable). Vitamin E and the polyphenols in cold pressed mustard oil neutralise the free radicals generated by UV and pollution, reducing the rate of collagen degradation and cell membrane damage.
How to use: Apply 2–3 drops to cleansed skin at night. Massage gently into the face and neck. Leave overnight. The skin absorbs the oil during sleep, when cellular repair processes are most active.
Best for: Fine lines, dull skin, skin exposed to high pollution (relevant for Gurgaon residents), premature aging.
Benefit 3: Acne Treatment and Prevention
This is counterintuitive — applying oil to acne-prone skin seems wrong. But cold pressed mustard oil's antibacterial properties make it effective against the bacteria that cause acne, and its non-comedogenic fatty acid profile means it does not clog pores for most skin types.
The mechanism: Acne is caused primarily by Propionibacterium acnes (now reclassified as Cutibacterium acnes) — a bacterium that colonises blocked pores and triggers inflammation. AITC in cold pressed mustard oil has demonstrated antibacterial activity against this organism in laboratory studies. The anti-inflammatory properties of AITC also reduce the redness and swelling of existing acne lesions.
Important caveat: Mustard oil is not suitable for all acne-prone skin types. People with very oily skin or cystic acne should patch-test carefully. The oil works best for mild to moderate acne in people with normal to dry skin.
How to use: Apply a very small amount (1–2 drops) as a spot treatment to individual acne lesions. Do not apply all over the face if you have oily skin. Leave overnight.
Benefit 4: Cracked Heels and Rough Skin
Cold pressed mustard oil is one of the most effective treatments for severely cracked heels — a common problem in North India, particularly in winter and during sandal-wearing months.
How to use:
- Wash and dry feet thoroughly
- Apply a generous amount of cold pressed mustard oil to heels and soles
- Massage for 5 minutes, focusing on cracked areas
- Cover with cotton socks
- Leave overnight
- Wash off in the morning
Repeat nightly for 2 weeks. The combination of MUFA occlusion (sealing in moisture), Vitamin E (supporting skin repair), and AITC (preventing secondary bacterial infection in cracked skin) makes this treatment highly effective.
Benefit 5: Fungal Skin Infections
The antifungal properties of AITC make cold pressed mustard oil an effective topical treatment for mild fungal skin infections — athlete's foot, ringworm, and intertrigo (skin fold infections).
How to use: Apply a thin layer of cold pressed mustard oil to the affected area twice daily. Continue for 2 weeks after symptoms resolve to prevent recurrence.
Note: For severe or spreading fungal infections, consult a dermatologist. Mustard oil is appropriate for mild, localised infections.
Benefit 6: Sunburn Relief
The anti-inflammatory properties of cold pressed mustard oil — from both AITC and Omega-3 fatty acids — provide relief from mild sunburn. The Vitamin E content also supports skin repair after UV damage.
How to use: Apply cool (not warm) cold pressed mustard oil to sunburned skin. The cooling sensation from AITC provides immediate relief. Leave on for 30–60 minutes, then rinse off with cool water.
Note: Do not apply to severely burned, blistered, or broken skin.
Benefit 7: Lip Care
Cold pressed mustard oil is an effective treatment for severely chapped lips — more effective than most commercial lip balms for very dry lips.
How to use: Apply a small amount to lips before bed. Leave overnight. The MUFA content seals in moisture; the Vitamin E supports lip skin repair.
How to Use Mustard Oil on Skin: Key Rules
Always patch-test first
Apply a small amount to the inner wrist or behind the ear. Wait 24 hours. If no redness or irritation appears, proceed with full application. Some people with sensitive skin react to AITC.
Use cold pressed (kachi ghani) only
Refined mustard oil has lost the AITC and most of the Vitamin E that make it effective on skin. For skin use, only cold pressed mustard oil provides the full benefit.
Less is more
Mustard oil is potent. 2–3 drops is sufficient for the face. A teaspoon covers the full body. Using too much leaves a residue and can cause irritation.
Apply to damp skin for moisturisation
For moisturising purposes, apply immediately after bathing while skin is still slightly damp. The oil seals in the water from the bath, dramatically improving hydration compared to applying to dry skin.
Avoid the eye area
AITC can cause significant irritation if it contacts the eyes or mucous membranes. Keep mustard oil away from the eye area.

| Eczema | Caution | Some studies show benefit; others show irritation — consult dermatologist |
Frequently Asked Questions
Is mustard oil good for skin? Yes. Cold pressed mustard oil is an effective skin treatment due to its Vitamin E content (antioxidant, anti-aging), MUFA profile (deep moisturisation, reduces water loss), allyl isothiocyanate (antibacterial, antifungal, anti-inflammatory), and beta-sitosterol (skin barrier support). It is particularly effective for dry skin, cracked heels, and mild fungal infections.
Can I apply mustard oil on my face daily? Yes, for most skin types — particularly dry and normal skin. Apply 2–3 drops to cleansed, damp skin. Avoid the eye area. People with oily or acne-prone skin should patch-test first and use sparingly.
Does mustard oil darken skin? No. There is no scientific evidence that mustard oil darkens skin. This is a common misconception. Mustard oil contains Vitamin E and antioxidants that protect against UV-induced pigmentation — if anything, it may help prevent darkening from sun exposure over time.
Can mustard oil remove tan? Mustard oil does not directly remove existing tan. However, its Vitamin E and antioxidant content supports skin cell turnover and reduces oxidative pigmentation over time. For active tan removal, combine mustard oil with lemon juice (apply for 20 minutes, then rinse) — the lemon provides mild exfoliation while the mustard oil moisturises.
Is mustard oil good for dry skin in winter? Yes — it is one of the best natural treatments for dry skin in winter. Apply to damp skin after bathing. The MUFA content creates an occlusive barrier that prevents moisture loss throughout the day. For severely dry skin, apply again before bed.
Does mustard oil clog pores? Cold pressed mustard oil is generally non-comedogenic for most skin types due to its MUFA-dominant fatty acid profile. However, people with very oily skin or large pores should patch-test first, as individual responses vary.
Which mustard oil is best for skin — cold pressed or refined? Cold pressed (kachi ghani) mustard oil is significantly better for skin. It retains allyl isothiocyanate (antibacterial, anti-inflammatory), full Vitamin E content (15–20mg vs 5–8mg in refined), and natural antioxidants. Refined mustard oil loses these compounds during high-heat processing and provides primarily occlusive moisturisation without the additional benefits.
