Does castor oil help with wrinkles? To put it simply and honestly: castor oil won't make wrinkles disappear, but it can make mature skin—which tends to feel drier and lose moisture more quickly—temporarily look more supple, comfortable, and well-nourished. We started More Natural after searching for pure skincare solutions for our own sensitive skin, and castor oil was a constant in our discoveries. What makes this oil truly unique is its high concentration of ricinoleic acid, a fatty acid that is virtually non-existent in other plant-based oils.1 In this article, you will learn eight ways to use castor oil for mature skin, how to best dilute it, and what to pair it with. For more background on caring for mature skin, read our article on understanding skin aging, and for its full range of uses, explore our guide on what castor oil is good for.
1. What makes castor oil unique
Castor oil is extracted from the seeds of the castor oil plant (Ricinus communis) and stands out due to its high content of ricinoleic acid—around 85 to 95 percent.1 This hydroxy fatty acid is rarely found in other plant-based oils and is responsible for the oil's characteristically thick, viscous texture.
Because of this texture, castor oil forms a protective layer on the skin that limits moisture evaporation. Ricinoleic acid has also been studied for its anti-inflammatory and soothing properties; in experimental models, topically applied ricinoleic acid reduced swelling and the inflammatory response.2 We are deliberately cautious here, as this research was largely conducted in laboratory and animal models, rather than large-scale human clinical trials. We cold-press our own castor oil at a maximum of 35°C (95°F), keeping it hexane-free and storing it in dark amber glass to ensure that the naturally occurring fatty acids are optimally preserved.
Our philosophy: castor oil softens the appearance of fine lines by keeping the skin supple and hydrated, but it does not reverse the aging process. We won't promise you a completely smoothed face—even though that would be an easy sell. Instead, think of castor oil as a deeply comforting night treatment rather than an anti-wrinkle cure. That is what we expect from it, and precisely why we do use it every single night.
Due to its rich texture, castor oil is best used diluted for most people, blended with a lighter oil. Applying it pure to the face can feel overly heavy for many skin types. Always start with a small amount and perform a patch test.
2. Eight ways to use castor oil
1. Castor oil as a cleansing oil
Castor oil is highly effective at dissolving makeup, sunscreen, and sebum. Apply a small amount to a dry face and gently massage in circular motions. Remove the oil with a warm, damp washcloth or rinse with lukewarm water. This works beautifully as the first step in a double-cleansing evening routine, followed by a second gentle cleanse with water or a mild facial cleanser.
2. Castor oil blended with jojoba oil
Jojoba oil has a composition that closely resembles the skin's natural sebum and is quickly absorbed. Blended with castor oil, it creates a lighter texture that is much easier to spread. Mix one part castor oil with three parts jojoba oil and apply the mixture in the evening to clean skin. Do not rinse. Suitable for most skin types, including normal or combination skin.
3. Castor oil and argan oil for drier mature skin
Argan oil is rich in oleic acid and vitamin E, feeling deeply nourishing on drier mature skin. Paired with castor oil, this blend leaves the skin feeling comfortable and supple. Mix one part castor oil with two parts argan oil. Apply the mixture in the evening as your final skincare step and do not rinse.
4. Castor oil with rosehip oil for a lighter texture
Rosehip oil has a lighter texture than argan oil and is rich in essential fatty acids and antioxidants. Combined with castor oil, it yields a blend that spreads easily and feels comfortable on mature skin that isn't excessively dry. Mix one part castor oil with two to three parts rosehip oil. Store rosehip oil in a cool, dark place due to its sensitivity to oxidation.
5. Castor oil around the eyes
The skin around the eyes is thinner and more sensitive than the rest of the face and often tends to feel dry. Castor oil can be applied here carefully, always diluted with a lighter oil. Use your ring finger, which exerts the least pressure, to gently pat a very small amount of the blend around the eye area. Avoid direct contact with the eyes. Never use pure castor oil around the eyes due to its heavy texture. If you are looking for castor oil specifically to target puffiness or dark circles, read our dedicated blog post on how to naturally reduce under-eye bags.
6. Castor oil as a night treatment for dry areas
Dry areas such as the cheeks, neck, or décolletage can benefit from extra nourishment overnight. Mix castor oil with baobab oil or macadamia oil to create a richer night blend for target areas. Apply a thin layer to the skin after applying your hydrosol and optional serum. Do not rinse.
7. Castor oil with rose water as an intermediate step
Castor oil adheres better to slightly damp skin than to completely dry skin. First, mist your skin with rose water and let it partially absorb. Then, immediately apply the castor oil blend while the skin is still slightly damp. This improves absorption and ensures a more comfortable feel. Additionally, rose water has a mild pH that complements the skin's natural acidity.
8. Castor oil as a facial massage oil
A brief facial massage with a castor oil blend makes for a relaxing weekly ritual. Warm a few drops of the mixture between your palms and gently massage your face using upward motions for two to three minutes. The warmth of your hands helps to distribute the oil. Wipe away any excess product with a warm, damp cloth, or let the rest absorb as overnight nourishment.
Our organic cold-pressed castor oil is intended strictly for external use. All of the oils mentioned in these combinations can also be found in our collection for mature skin.
3. Important considerations
Always perform a patch test before incorporating castor oil into your routine: apply a small amount to the inside of your elbow and wait 24 hours. Always use a modest amount and apply the oil thinly. Avoid direct contact with the eyes. Do not use castor oil on irritated, inflamed, or damaged skin.
Castor oil has a relatively high comedogenicity rating, meaning it can clog pores on certain skin types. For mature skin, which produces less sebum, this risk is lower than for oily or acne-prone skin. Always dilute the oil and observe how your skin responds for two to three weeks before drawing conclusions. If irritation persists, discontinue use.

Frequently asked questions
Does castor oil really help with wrinkles?
No, not in the sense of erasing wrinkles. Castor oil keeps the skin supple and sealed, which can temporarily soften the appearance of fine lines, but there is no evidence that it reverses aging. You will often notice a direct, smoothing effect within a few weeks, but it is cosmetic and temporary unless maintained. Think of it as a deeply comforting night treatment.
Can I use castor oil pure on my face?
For most people, pure castor oil is too heavy for the face. The thick texture is difficult to spread and can feel suffocating. Diluting it with a lighter oil, such as jojoba or argan, provides a better consistency and easier application. A ratio of one part castor oil to two or three parts carrier oil is a great starting point.
What does castor oil smell like?
Castor oil has a subtle, slightly earthy scent that may not appeal to everyone. Cold-pressed organic castor oil has a less pronounced aroma than refined variants. When combined with rosehip or argan oil, the scent is naturally masked. The smell also dissipates quickly after the oil is applied to the skin.
When should I use castor oil: morning or evening?
Due to its rich texture, castor oil is best suited as an evening or night treatment. The evening allows more time for absorption, and you won't need to layer sunscreen over it. It can also be used as the first step of an evening oil-cleansing routine. Daily daytime use is possible but generally less practical due to its heavy consistency.
What is the shelf life of castor oil?
Castor oil is naturally more stable than oils with a high concentration of polyunsaturated fatty acids, such as rosehip oil. Once opened, it typically has a shelf life of one to two years when stored in a cool, dark place. An oil that smells rancid has oxidized and is no longer suitable for use on the skin.
Is castor oil suitable for the neck and décolletage?
Yes. The neck and décolletage are areas that are often drier than the face and where signs of aging typically show. Castor oil, blended with a lighter oil, works wonderfully as a night treatment for these zones. Apply the blend using upward sweeping motions, using the same amount as you would for the face.
Is castor oil good for your face?
Castor oil is highly beneficial for facial care due to the film-forming properties of ricinoleic acid, which limit moisture loss. It is too thick to be used pure; always dilute it with jojoba or argan oil in a 1-to-2 ratio. A drop of this blend as a night treatment provides a protective lipid barrier. If you have acne-prone skin, proceed with caution and always perform a patch test.
Castor oil face reviews: what do users experience?
Users of castor oil on the face report a more supple, comfortable-feeling skin that feels less tight after cleansing within two to four weeks. The most common mistake mentioned is using too much: a tiny, diluted amount is plenty. Those with dry eye areas report the greatest benefits when applying it carefully around the eyes.
Castor oil for eyebrows and eyelashes: how do you use it?
Castor oil is traditionally applied to eyebrows and eyelashes as a nourishing overnight treatment. Use a clean spoolie or cotton swab to gently coat your brow hairs or lashes with a small amount of oil. Avoid contact with the eye itself. It is not scientifically proven to stimulate hair growth, but is widely used as a conditioning and protective product.
How long should you leave castor oil in your hair or skin?
As a nighttime skincare step, castor oil can be left on the skin overnight. As a hair mask, let it sit for thirty minutes up to a full night. For a hot oil treatment, leave it on for about an hour. Leaving it on longer than overnight offers no additional benefit. Always rinse hair thoroughly after a mask; you may need to shampoo twice as castor oil can be stubborn to wash out.
Is castor oil suitable for sensitive skin?
Castor oil is generally well tolerated, but ricinoleic acid can cause mild reactions in some individuals. Always perform a patch test: apply diluted castor oil to the inside of your wrist and wait 24 hours. Afterward, begin by applying a small amount to a tiny portion of your face before wider use.
