The controversy around seed oils mainly revolves around their use in food, particularly due to concerns about high omega-6 fatty acid content, which can contribute to inflammation if not balanced with omega-3s. However, the concerns about seed oils in skincare are quite different.
Seed Oils in Skincare
Seed oils are commonly used in skincare products for their nourishing and moisturizing properties. They are often rich in vitamins, antioxidants, and fatty acids, which can benefit the skin by:
Strengthening the skin barrier: Oils like sunflower seed oil and safflower oil are lightweight and can lock in moisture.
Soothing and repairing: Oils such as rosehip and evening primrose have anti-inflammatory properties and can promote skin healing.
Providing antioxidants: Many seed oils contain vitamin E and other antioxidants that help protect the skin from free radical damage.
Are They Dangerous?
In skincare, seed oils are generally considered safe when used correctly and in their pure, unprocessed form. They don't pose the same risks as when consumed in excess. The key concerns to be aware of include:
Oxidation: Some seed oils, especially polyunsaturated ones, can oxidize when exposed to heat, light, or air, leading to free radical production. However, this is more of a formulation issue in products than a direct danger.
Skin sensitivity: Some people may have allergies or sensitivities to certain seed oils.
Comedogenicity: Certain oils, like soybean or sunflower, may clog pores in acne-prone skin.
Key Differences Between Food and Skincare Use
1. Oxidative Stress in Food: When seed oils are heated during cooking, they can produce harmful compounds. This is not a concern in skincare, as oils are not heated during application.
2. Consumption vs. Topical Use: Seed oils in skincare are not ingested and don't contribute to dietary omega-6 imbalances.
3. Processing: Cold-pressed and unrefined seed oils used in skincare are typically less processed than the refined versions used in cooking.
Conclusion
Seed oils in skincare are not inherently dangerous and can be very beneficial when chosen and used appropriately. The concerns about seed oils in food don't directly translate to their use on the skin.
In effect, seed oils seem to be MADE for topical use, whereas NOT for ingestion.
