Yes, skin can absorb oil, but the degree of absorption depends on several factors, including the type of oil, the condition of the skin, and the application method.
- Smaller, oil-based molecules, like essential oils and fragrances, are more easily absorbed through the skin. This is because they can penetrate the skin's outer layer, the epidermis, more readily.
- Larger molecules, like those found in many moisturizers, are less likely to be absorbed. Instead, they tend to stay on the surface of the skin, providing a barrier to moisture loss.
- Hydrated skin absorbs oil more effectively than dehydrated skin. This is because hydrated skin has a more intact barrier function, allowing for better penetration of oil molecules.
- Certain oils, like castor oil and soybean oil, have been shown to enhance the absorption of other substances into the skin. This suggests that they can act as penetration enhancers, increasing the effectiveness of skincare products.
While oils can penetrate the skin to a certain extent, it's important to note that they don't add moisture to the skin. Oils are hydrophobic, meaning they repel water. Therefore, they can't directly hydrate the skin.
However, oils can help to seal in moisture, preventing the skin from losing water. This can make the skin feel softer and smoother.
