Carrot Seed Oil is one of those ingredients that gets misrepresented more than almost any other in the DIY skincare world. It is frequently — and incorrectly — claimed to offer SPF protection. It does not. What it does offer is a genuinely impressive antioxidant and carotenoid profile that makes it a valuable active oil in mature-skin, brightening, and skin-conditioning formulations. Understanding what it actually does — and what it doesn't — is the starting point for using it effectively.
There are also two distinct products sold under the name "Carrot Oil": Carrot Seed Oil (cold-pressed from the seeds of Daucus carota) and Carrot Infused Oil (a macerated oil where carrot root is infused into a carrier oil). They have different compositions, different colours, and different formulation applications — and this guide covers both.
Carrot Seed Oil vs. Carrot Infused Oil: What's the Difference?
| Property | Carrot Seed Oil | Carrot Infused Oil |
|---|---|---|
| Source | Cold-pressed from Daucus carota seeds | Carrot root macerated in a carrier oil (usually Sunflower or Olive) |
| INCI Name | Daucus Carota Sativa Seed Oil | Varies (e.g., Helianthus Annuus Seed Oil, Daucus Carota Sativa Root Extract) |
| Colour | Pale yellow to light amber | Deep orange — significant colour impact on formulations |
| Key Actives | Carotol (sesquiterpene), tocopherols, phytosterols | Beta-carotene (pro-Vitamin A), carotenoids |
| Skin Benefit | Antioxidant, skin-conditioning, anti-aging | Antioxidant, skin tone, colour-imparting (tanning effect) |
| Typical Usage Rate | 1–10% | 5–20% |
| Best For | Anti-aging serums, facial oils, skin-conditioning | Tanning oils, body butters, bronzing formulations |
A widely circulated claim suggests that Carrot Seed Oil provides SPF 38–40. This claim is not supported by peer-reviewed research or regulatory testing. The original source was a single, methodologically flawed study that has never been replicated. Do not make SPF claims for any carrier oil, including Carrot Seed Oil. If your formulation requires sun protection, use a tested, cosmetic-grade UV filter such as Zinc Oxide at a validated concentration, and ensure your product is tested to TGA/ARTG standards before making any SPF claims.
Fatty Acid Profile of Carrot Seed Oil
| Fatty Acid | Approximate % | Skin Benefit |
|---|---|---|
| Petroselinic Acid (unusual Omega-6) | 60–76% | Emollient, skin-softening — unusual fatty acid rarely found in other carrier oils |
| Linoleic Acid (Omega-6) | 10–20% | Skin barrier repair, sebum regulation |
| Oleic Acid (Omega-9) | 5–15% | Emollient, enhances penetration of actives |
| Palmitic Acid | 3–6% | Emollient, formula stability |
The dominant fatty acid in Carrot Seed Oil is petroselinic acid — an unusual Omega-6 isomer that is rarely found in other carrier oils. Beyond its fatty acids, the oil contains carotol (a sesquiterpene alcohol that is its primary bioactive compound), beta-carotene, tocopherols, and phytosterols — all contributing to its antioxidant and skin-conditioning properties.
INCI Name: Daucus Carota Sativa Seed Oil
Colour: Pale yellow to light amber — relatively neutral in formulations
Odour: Distinctive earthy, slightly woody — use at low percentages to manage scent
Comedogenic Rating: 1 (very low)
Skin Feel: Medium — absorbs well
Shelf Life: 12 months (store away from heat and light)
Typical Usage Rate: 1–10% (used as an active oil, not a primary carrier)

How Carrot Seed Oil Compares to Similar Active Oils
| Oil | Key Actives | Colour Impact | Usage Rate | Best For |
|---|---|---|---|---|
| Carrot Seed Oil | Carotol, beta-carotene, tocopherols | Low | 1–10% | Anti-aging, antioxidant, skin-conditioning |
| Carrot Infused Oil | Beta-carotene, carotenoids | High (deep orange) | 5–20% | Tanning oils, bronzing, body butters |
| Sea Buckthorn Oil | Carotenoids, palmitoleic acid, Vitamin E | Very high (intense orange) | 0.5–2% | Anti-aging, barrier repair, colour-imparting |
| Rosehip Oil | Trans-retinoic acid, linolenic acid | Low (pale gold) | 5–20% | Anti-aging, pigmentation, barrier repair |
| Bakuchi Oil | Bakuchiol (natural retinol alternative) | Low | 3–5% | Anti-aging, retinol alternative, sensitive skin |
| Vitamin E Oil | Tocopherol (antioxidant) | Very low | 0.5–1% | Antioxidant protection, formula preservation |
Formulation Applications
Facial Oils for Mature Skin
Carrot Seed Oil is best used at 3–8% as an active oil in mature-skin facial oil blends. Its carotol and tocopherol content contribute antioxidant protection, while its petroselinic acid provides a unique emollient effect. Pair with Rosehip Oil for natural retinoids, Bakuchi Oil at 3–5% as a retinol alternative, and Argan Oil or Jojoba Oil as the primary carrier.
Tanning and Bronzing Formulations
For tanning oils and bronzing body butters, Carrot Infused Oil is the more appropriate choice due to its high beta-carotene content and deep orange colour. Use at 10–20% alongside Coconut Oil, Sesame Seed Oil, and Sunflower Oil. Always include a prominent cosmetic-only disclaimer — these oils do not provide UV protection.
Brightening and Skin Tone Formulations
The carotenoid content of Carrot Seed Oil makes it a useful addition to brightening formulations. Combine at 5% with Sea Buckthorn Oil at 1% (for its intense carotenoid content), Rosehip Oil at 15%, and a stable primary carrier like Jojoba Oil or Argan Oil.
Body Butters and Balms
In body butters, Carrot Infused Oil at 5–10% adds a warm, golden tone and antioxidant benefit. Combine with Shea Butter, Mango Butter, and Cocoa Butter for a rich, nourishing body butter. Add Vitamin E Oil at 1% to protect the formula.
DIY Recipe: Antioxidant Facial Oil for Mature Skin
This formula uses Carrot Seed Oil as an active at 5%, supported by Rosehip Oil and Bakuchi Oil as mature-skin actives, with Argan Oil and Jojoba Oil as the primary carriers.
| Ingredient (INCI Name) | % (w/w) | Weight (for 100g) |
|---|---|---|
| Argan Oil (Argania Spinosa Kernel Oil) | 40.0% | 40.0g |
| Jojoba Oil (Simmondsia Chinensis Seed Oil) | 25.0% | 25.0g |
| Rosehip Oil (Rosa Canina Seed Oil) | 20.0% | 20.0g |
| Bakuchi Oil (Psoralea Corylifolia Seed Oil) | 5.0% | 5.0g |
| Carrot Seed Oil (Daucus Carota Sativa Seed Oil) | 5.0% | 5.0g |
| Sea Buckthorn Oil (Hippophae Rhamnoides Fruit Oil) | 2.0% | 2.0g |
| Vitamin E Oil (Tocopherol) | 1.0% | 1.0g |
| TOTAL | 98.0% | 98.0g |
Note: This formula intentionally totals 98% to allow 2% flexibility for a fragrance or essential oil addition of your choice (e.g., Frankincense Essential Oil at 1–2% for a classic, grounding scent profile). If no fragrance is added, increase Argan Oil to 42% to reach 100%.
Method: Combine all oils in a clean beaker and stir to blend. No heat required. Fill into 30ml dropper bottles. No preservative is required as this is an anhydrous (water-free) formula. Store away from heat and light, make small batches, and discard if it smells rancid.

Frequently Asked Questions
No. Carrot Seed Oil does not provide SPF protection. The claim that it offers SPF 38–40 originates from a single, methodologically flawed study that has never been replicated in peer-reviewed research. No regulatory body — including the TGA in Australia, the FDA in the US, or the EU Cosmetics Regulation — recognises Carrot Seed Oil as a UV filter. If your formulation requires sun protection, use a tested cosmetic-grade UV filter such as Zinc Oxide, and ensure your product is tested to the relevant standard before making any SPF claims.
These are two entirely different products. Carrot Seed Oil is a cold-pressed carrier oil from the seeds of Daucus carota — it is used at 1–10% in formulations for its antioxidant and skin-conditioning properties. Carrot Seed Essential Oil is a steam-distilled essential oil from the same seeds — it is highly concentrated, used at 0.1–0.5% maximum, and has a very strong, distinctive earthy scent. They are not interchangeable. The carrier oil is the appropriate choice for most skincare formulations.
Carrot Seed Oil (cold-pressed) has a pale yellow to light amber colour and will not noticeably affect skin tone at typical usage rates of 1–10%. Carrot Infused Oil, however, has a deep orange colour due to its high beta-carotene content and can impart a warm, golden tone to the skin — which is why it is commonly used in tanning and bronzing formulations. At high usage rates (15–20%), Carrot Infused Oil can temporarily tint the skin orange. This effect is temporary and washes off.
Carrot Seed Oil is an oil-phase ingredient and is not water-soluble. It cannot be directly added to a water phase without an emulsifier. To include it in a water-based formulation such as a lotion or cream, it must be incorporated into the oil phase alongside other oil-phase ingredients, with an emulsifier such as Olivem 1000 or Emulsifying Wax NF used to combine the oil and water phases. In oil-only formulations (serums, facial oils, body oils), it can be used directly without any emulsification.
