No, pure emu oil will not clog pores. There are many brands in the market, and some may include some other ingredients but ours is 100% pure and pharmaceutical grade. Our pure emu Oil is natural and non-toxic, non-comedogenic (meaning that it does not clog pores), hypo-allergenic (non- irritating) and is gentle for all skin types. A study on the biological activity of Emu Oil found that the lipids in the oil mimic those of the human skin, providing an efficient trans-dermal delivery system that can deeply penetrate the skin’s surface. Many customers who have tried other brands of emu oil found that some has white residue, and the liquid clogs up and it’s not easy to spread. If the emu oil is not pure, it will also not provide the anti-inflammatory effect.
