Using oils appropriately in skincare is essential for maintaining good health. Here’s a detailed guide on which oils are beneficial and which ones can be harmful.
Factors
Before we get into the list of oils, there are important factors to consider:
- Smoke Point: The temperature at which an oil begins to smoke and decompose, potentially forming harmful compounds. Oils with higher smoke points are better suited for high-heat cooking.
- Balance: A healthy diet requires a balance of omega-3 and omega-6 fatty acids. Western diets often have high levels of omega-6, which can lead to inflammation. Ensuring sufficient omega-3 intake is crucial.
- Processing: Highly processed oils can lose beneficial nutrients and gain harmful compounds. Unrefined, cold-pressed, and extra virgin oils are generally healthier options.
- Storage: Proper storage is essential to maintain the quality of oils. Keep them in a cool, dark place to prevent oxidation.
- Variety: Incorporating a variety of healthy fats into your diet provides a range of beneficial nutrients.
The quality and source of the oil, along with how it is used in cooking, significantly impact its health benefits or risks. Using a variety of healthy oils and fats, and choosing them based on their smoke points, can greatly enhance your overall nutritional well-being.

Oils to Avoid Due to Inflammatory Properties
Certain oils can contribute to inflammation and other health issues due to their high levels of omega-6 fatty acids, trans fats, or the presence of harmful compounds from processing. Here are some oils you should consider avoiding:
Oils High in Omega-6 Fatty Acids and Trans Fats
These oils are typically high in omega-6 fatty acids and may contain trans fats, which can promote inflammation and negatively impact health.
Soybean Oil
- Concerns: High in omega-6 fatty acids, potentially contributing to inflammation.
- Smoke Point: 450°F (232°C).
Corn Oil
- Concerns: Similar to soybean oil, also high in omega-6 fatty acids.
- Smoke Point: 450°F (232°C).
Vegetable Shortening
- Concerns: Often contains trans fats, which are detrimental to health.
- Smoke Point: Varies depending on the brand and composition.
Margarine
- Concerns: Non-dairy versions can contain trans fats.
- Smoke Point: Varies.
Canola Oil
- Concerns: While it has a balance of omega-3 and omega-6, the refining process and potential GMO concerns may be undesirable for some.
- Smoke Point: 400°F (204°C).
Sunflower Oil
- Concerns: High in omega-6 fatty acids, requires a balanced omega-3 intake to reduce inflammation.
- Smoke Point: 440°F (227°C) for high-oleic versions.
Light Sesame Oil
- Concerns: High in polyunsaturated fats (omega-6 fatty acids), which can contribute to inflammation if consumed excessively.
- Smoke Point: 410°F (210°C), suitable for moderate to high-heat cooking.
Avoiding these oils can help reduce inflammation and support overall health.
