Thick and luscious, Castor Oil feels glorious on your skin, especially when you smooth it on your face before bed. It’s rich texture alone makes you feel like your skin will plump up beautifully overnight. 

Maybe you’ve felt like slathering this golden oil filled with skin-loving fatty acids onto your face, letting the vitamins and nutrients do their handiwork. 

But then, you might have stopped suddenly and thought: “Wait a minute! Castor Oil is so thick and rich, will it clog my pores?”

Is this you? 

If you’re worried that Castor Oil could clog your pores, you’re not alone. There’s been plenty of confusion and debate about whether Castor Oil can clog pores or cause acne. But rest easy, because in this blog, we’ll explore the comedogenicity of Castor Oil, and delve into the reasons why it has been heralded as an amazing skin elixir, thanks to its rich composition of vitamins and fatty acids.

Find out what are the benefits of Queen of the Thrones Castor Oil

Key Points:

    • Castor Oil is a non-comedogenic oil with a rating of 0-1, meaning it is not likely to clog your pores.
    • Castor Oil has natural anti-inflammatory and antibacterial qualities that may help support healthier looking skin
    • Castor Oil is an amazing moisturizer, and it is safe for most skin types.

Will Castor Oil clog my pores?

OK – the short answer: Castor Oil has a comedogenic rating of 0-11, which means that it most likely will not clog your pores or cause skin irritation. Or put another way, Castor Oil is a non-comedogenic oil.

What does comedogenic mean?

Comedogenicity refers to the ability of a substance, typically found in skincare and cosmetic products, to clog pores and potentially cause comedones. Comedones are non-inflammatory acne lesions more commonly known as pimples! 

Yes, we’re talking about those all-too-familiar blackheads and whiteheads that show themselves when your hair follicles become blocked by excess oil, dead skin cells, and other debris. So, if something is non-comedogenic, it means that it will not contribute to clogged pores and breakouts. Castor Oil is non-comedogenic.

What makes a substance comedogenic?

A substance is comedogenic if it blocks pores and results in comedones – AKA pimples. It’s important to remember that individual ingredients can be non-comedogenic but may become comedogenic when mixed with other substances. For example, Castor Oil is non-comedogenic, but if you mix it with beeswax or red dye (as many cosmetics do), then the mixture can be pore-clogging.

What is the comedogenic scale?

The comedogenic scale is a rating from 0 to 5. Simply put, if a substance has a rating of 0 it is considered non-comedogenic, meaning that it is less likely to clog your pores. Substances with higher ratings are more likely to cause clogged pores and lead to pimples, acne, breakouts, zits, and whatever else you choose to call those dreaded lesions.

But again, if you love Castor Oil, you’re in luck because it has a very low comedogenic rating. So chances are, you can use it as a makeup remover and moisturizer and know that it will not contribute to breakouts!

Understanding the comedogenicity of skincare and cosmetic products is especially important if you’re prone to acne or if you have sensitive skin. So, if this is you, be sure to look for non-comedogenic products that will minimize the risk of pore clogging, like organic Castor Oil.

Is Castor Oil good for skin

So, now you know that despite the thick and viscous nature of Castor Oil, it has a very low comedogenic rating. But you might be thinking, How can a rich, thick oil like Castor Oil NOT clog my pores? 

Castor Oil is an ancient, versatile, and beloved vegetable oil that has been used for centuries for its numerous self-care and beauty benefits, and one of its most popular applications is in skincare. 

While it might be extra thick and even sticky, Castor Oil may help balance the bacteria that live on the surface of your skin to prevent future breakouts. Why? Because Castor Oil has natural  antibacterial properties2, and your skin has its own microbiome. 

But let’s take a closer look at the main components of Castor Oil and what makes it so well suited for skincare.

Queen of the Thrones skin loving nutrients in Castor oil

  1. Ricinoleic acid

Castor Oil is rich in ricinoleic acid, and by rich, we’re talking like 85-92% of the total fatty acid3 content. And this is especially impressive when you consider that ricinoleic acid is known for its remarkable anti-inflammatory and antibacterial properties. When you apply it to your skin, ricinoleic acid may support irritation, reduce redness, and alleviate inflammation4, making it an excellent choice if you have sensitive or acne-prone skin. 

  1. Vitamin E

Vitamin E is a potent antioxidant that plays a crucial role in protecting the skin from free radicals and environmental damage. Castor oil contains a significant amount of vitamin E,5 which helps in maintaining skin health and preventing premature aging. The antioxidant properties of vitamin E can also aid in reducing the appearance of scars and blemishes.

  1. Omega Fatty Acids

Castor Oil contains essential omega fatty acids, such as omega-6 and omega-9. These fatty acids are vital for maintaining the skin’s moisture barrier, keeping it hydrated and nourished. Castor Oil also contains high percentages of other fatty acids including linoleic, oleic, stearic, palmitic, dihydroxystearic acid, linolenic acid, and eicosanoic acid6.

  1. Polyphenols

Polyphenols are a group of natural compounds found in various plant-based foods, including fruits, vegetables, herbs, spices, tea, dark chocolate, and wine. These compounds have antioxidant properties, enabling them to counteract harmful free radicals that might otherwise damage your cells and elevate the risk of disease.

Polyphenols are believed to support inflammation balance which is very important for clear, radiant skin.

Who should use Castor Oil for skincare?

Castor Oil works beautifully as part of a general skincare routine. If you have mature or very dry skin, then you’ll especially love its moisturizing qualities. 

If your skin is oily, then you might only want to use Castor Oil on your face a couple of times a week, because while Castor Oil is non-comedogenic and won’t clog pores, it is an oil. We’re all biochemically unique, so try it on a small area of your skin first to see how it feels. 

If you have acne, then Castor Oil may help support the inflammation. Keep in mind that acne can be fungal or bacterial. Castor Oil may work better for bacterial acne, but if you have the fungal variety, any oil could potentially exacerbate your symptoms. Again, you may want to try it on a small area of your skin first to be sure if Castor Oil is right for you.

How to use Castor Oil for skincare

Are you ready to add Castor Oil to your skincare routine? Interestingly, you might be using Castor Oil already without even realizing it. You see, Castor Oil has been used as an ingredient in cosmetics, shampoos, soaps, bath oils, and countless other products for many years! 

But if you want to add this luscious oil to your skin in its pure form, then stick to brands that are 100% pure, organic, hexane-free, cold or expeller pressed, and bottled in amber glass. 

Why? Because the quality of the oil contributes to its comedogenicity. Basically, if a substance is impure, it could clog your pores.

  • As part of a face mask: The anti-inflammatory and antibacterial properties in Castor Oil allow it to help dissolve impurities on your skin like make-up residue, while adding moisture and a protective barrier to help your skin stay hydrated.

  • Around your eyes for fine lines and wrinkles: Because Castor Oil is so rich and thick, it works especially well around your eyes to help improve the appearance of fine lines and wrinkles.

Wearing an eye compress to bed may even help support a deeper sleep while it adds moisture to the delicate skin around your eyes.
Castor Oil is an amazing moisturizer –  it has even been known to help reduce the appearance of age spots and hyperpigmentation7. In rare cases, a hypersensitivity reaction may occur, in which case you should discontinue use.
