Can Oils Enter into my Bloodstream?
This is a great article siting the difference in molecular weights of oils and which ones can enter your bloodstream and to what degree. Essential oils, being herbally created and much more concentrated and molecularly smaller can enter your bloodstream, when carrier oils typically penetrate only the first 3 layers, which is why oil based skincare does heal and change the appearance of your skin much better than chemical laden moisturizers most people buy without bothering to read the labels.
Oils are better for your skin because they block moisture into the layer beneath the application of oil and butter based moisture. If you do not adequately treat your skin with a protective layer and keep stripping your skin of natural oils and moisture by washing with chemical laden soaps and products, your skin will be drier and less flexible, even creating grounds for the development of eczema!
