Natural oils should be an essential part of every skincare routine. They are a valuable source of essential fatty acids, which are necessary for achieving healthy, elastic, and supple skin. However, not all oils are harmless and safe. Some of them can contribute to the formation of comedones. Instead of a radiant complexion, you may end up dealing with a whole range of skin problems. Who would want that? No one. That is why today we will explain what the comedogenicity rating of oils is and how to choose an oil-based product that suits your skin type.

Oils in Skincare

Depending on your skin type, natural oils can cleanse, moisturize, or be used as a targeted treatment to address specific skin concerns. In some cases, oils are used as a natural cleansing agent to remove makeup residue and other impurities from the skin. For people struggling with dryness and inflammation, oils can become a real skincare savior.
However, not all products provide the same benefits. Some oils have anti-inflammatory and antioxidant properties, while others may contribute to the formation of comedones and blackheads. In addition, strong essential oils should be used with caution. Lavender and tea tree oils may trigger allergic reactions, so before incorporating them into your skincare routine, it is recommended to consult a cosmetologist.
Who Should Be Careful When Using Oils?

Although the benefits of oils are significant, in some cases these products can harm the skin instead of helping to solve certain problems. Oils are not recommended for people who have:
1. Acne-prone skin – acne develops when skin pores become clogged with sebum, which can mix with dirt and impurities. Skincare in this case should be based only on products labeled as non-comedogenic.
2. Seborrheic dermatitis – around 11% of the world’s population struggles with this condition. It most often affects the scalp, but symptoms can also appear on the face. Itching, tightness, and skin flaking are unpleasant sensations that can be alleviated with over-the-counter treatments. Oily skin is more prone to seborrheic dermatitis, which develops as a result of a complex interaction between the immune system and the skin microbiome.
3. Rosacea – redness of the nose, cheeks, forehead, and chin. Treatment may include both medication and specialized procedures. People with rosacea often have a compromised skin barrier, which means oils may not only worsen the condition but also trigger increased breakouts.
Problematic skin requires a gentle and professional approach. A responsible skincare routine can help reduce severe symptoms and improve the overall condition of the skin.
What Is Comedogenicity?

So, we come to the main question. If the above concerns don't apply to you, you can safely consider using natural oils as part of your daily skincare routine. But don't rush into buying anything. First, you need to understand what comedogenicity is and what it means.
Comedogenicity is the ability of an oil to cause blackheads and clog pores. A level of 0 to 5 is determined on a special scale, where 0 indicates a completely safe oil, and 5 indicates a very high risk of breakouts. This product should only be incorporated into your skincare routine as directed by a doctor and under the supervision of a specialist.

Why do some oils clog pores while others do not? Everything depends on the composition of the product. Plant-based oils contain oleic, linoleic, lauric, stearic, and caprylic acids. However, the proportions of these components vary depending on the type of oil. When applied to the skin, oil interacts with its microbiome. Stearic acid can make sebum more viscous, making it harder for dead skin cells to shed properly. As a result, pores can become clogged, leading to breakouts.
Every skin type requires an individual approach to skincare. The choice of oil should also be conscious and well-considered. Misdiagnosing your skin concerns or choosing the wrong natural product can lead to inflammation, breakouts, and bumps on the skin. If you want to improve your skin rather than harm it, approach this process wisely.
Comedogenicity Ratings of Oils

Let’s classify all oils used in cosmetology according to their comedogenicity ratings. We will start with the most risky ones and gradually move on to plant-based oils that have a lower chance of clogging pores. Let’s get started.
Comedogenicity Rating 5
Wheat germ oil can work wonders for your skin while also potentially causing certain issues. Although it has the highest comedogenicity rating, it can be an excellent choice for dry and mature skin. To help reduce age-related changes, it is important to focus on products with strong regenerating and nourishing properties. When used under the guidance of a specialist, wheat germ oil can help restore the skin’s balance without causing unwanted effects.
Comedogenicity Rating 4

High-risk oils that are best suited for addressing specific local concerns. Coconut oil, cocoa butter, flaxseed oil, and palm oil have excellent nourishing properties and can work well in addressing issues such as scars.
Comedogenicity Rating 3
Products with a moderate comedogenic potential that can help combat dry skin. This category includes olive oil, soybean oil, as well as corn germ oil, cottonseed oil, carrot oil, chia oil, and marula oil.
Comedogenicity Rating 2
This list includes natural products that can be used by people with dry and normal skin types. Pumpkin seed oil, sesame oil, jojoba oil, avocado oil, apricot kernel oil, almond oil, green tea oil, macadamia oil, grape seed oil, and hazelnut oil have a moderately low comedogenicity rating.
Comedogenicity Rating 1

Comedogenicity Rating 1
An interesting category with an interesting selection of oils. The low rating means that these natural products can be used by almost everyone, excluding only people with very oily skin. So, what can you use without worrying about your skin’s health? Pomegranate seed oil, castor oil, elderberry oil, guava oil, sea buckthorn oil, rosehip oil, broccoli seed oil, babassu oil, meadowsweet oil, and many others.
Comedogenicity Rating 0
This is the safest category of oils, as they are extremely gentle on your pores. You can confidently consider every oil from this list, as the risk of developing comedones is virtually zero. Used in pure form or as an addition to creams, masks, or serums, you can choose argan oil, mango oil, hemp oil, sunflower oil, shea butter, safflower oil, chamomile oil, and calendula oil.
What can I say about this? I have personally experienced the effectiveness and safety of argan and sunflower oils. I add the first one to my serum and use it both during the day and at night, while the second works perfectly as the main ingredient in my homemade face masks. If you also enjoy making DIY skincare products, keep this in mind.

Choose an oil depending on your skin type

The choice of a facial treatment, regardless of whether it contains oils or not, should depend entirely on your skin type. Only in this way can you achieve the desired results and maintain healthy, beautiful, and youthful skin. Therefore, taking your skin type into account, I will provide recommendations on which oils are best suited for you. However, before introducing any oil into your routine, consult a cosmetologist.
1. Oily skin is all about lightness and comfort. In this case, you should use only oils that help regulate sebum production and do not clog pores. These include jojoba oil, grapeseed oil, and tea tree oil.
2. Dry skin requires products rich in fatty acids and vitamins. The product should not only moisturize the facial skin but also help restore the lipid barrier. The best solutions for these concerns are avocado oil, shea butter, argan oil, and almond oil.
3. Combination skin can be quite demanding. It needs help regulating sebum production in problematic areas while providing nourishment and vitamins to normal areas. Hazelnut oil and pomegranate seed oil can help address these needs.
4. Sensitive skin benefits from oils with soothing and calming properties. These include chamomile oil, calendula oil, and rosehip oil. Before using floral oils, it is recommended to perform a small patch test to check for individual sensitivity.
5. Problematic skin requires skincare with antibacterial properties and ingredients that help regulate sebum production. Tea tree oil and hemp oil have these beneficial properties.
Now that you know what comedogenicity is and which oils can be considered safe, it will be much easier to choose the right option from the list. Introduce natural products into your skincare routine carefully and monitor your skin’s reaction. Once oils become an integral part of your skincare routine, you will notice that your skin can quickly become healthier, smoother, more elastic, and more even.
