Castor Oil Comedogenic Rating
Rating
1
out of 5 (range 1)
Pore-clogging risk
LowUnlikely to clog pores for most people, including many with acne-prone skin.
Category
Carrier oil
Castor oil rates low at 1 thanks to its unique ricinoleic acid, and it is a common cleansing oil and lash conditioner despite its thick, tacky texture.
What a rating of 1 means
A rating of 1 keeps castor oil on the low end for clogging. It is thick and sticky, so it is usually blended with lighter oils rather than used alone, but it does not tend to clog pores on its own.
Fatty acid profile
Castor oil is almost entirely ricinoleic acid, a fatty acid found in few other oils. That structure gives it humectant-like properties and a cleansing pull, which is why it appears in oil cleansers and brow serums.
Key fatty acids: Ricinoleic acid, Oleic acid, Linoleic acid.
Profile: Dominated by the unusual ricinoleic acid.
Best for
- Oily skin
- Cleansing routines
- Lashes and brows
Use caution with
- Can feel sticky and draw out congestion at first
Who should use it
Oily and combination skin use castor in cleansing oil blends, while many people apply it to lashes and brows. It is best mixed with a lighter carrier rather than worn thick on the face.
How it compares to beef tallow
Castor oil is a thin-blend cleanser and conditioner, while beef tallow is a finishing moisturizer. They serve different steps, with castor often in the cleanse and tallow in the seal.
How to apply it
Blend castor with a lighter oil at roughly one part castor to three parts carrier so it spreads without feeling tacky.
Common questions
Is castor oil comedogenic?
Castor oil rates 1 and is low on the comedogenic scale. It is thick and sticky but does not tend to clog pores when blended with lighter oils.
Why is castor oil so sticky?
Its high ricinoleic acid content gives castor oil a dense, tacky texture, which is why it is usually mixed with a thinner carrier oil before use.
Can castor oil replace a moisturizer?
Castor oil works better as a cleansing or treatment oil than as a final moisturizer. A richer seal like beef tallow is a better last step for dry skin.
Want richness with a low comedogenic rating?
Beef tallow rates around 1 to 2 and mirrors skin sebum, which makes it an easy face swap if castor oil feels too heavy or clogging. Misun Health uses a single grass-fed ingredient with no fragrance or fillers.
