I've been using only oils for a couple of years, and my skin looks and feels better than ever! It does clean well and leaves the skin in excellent condition. Our skin is fairly absorbant, and I believe that nutricious, natural oils are like whole foods for the skin.
In the past I've used skincare from brands like Chanel, Shiseido, Kanebo, Estee Lauder and others. Their products generally smell and feel good, but they didn't make a difference for me. Maybe not so strange if you decipher their long lists of contents. They are typically filled with water, mineral oil, vegetal oils, silicones, moisturizing agents, preservatives and other chemicals and botanical extracts to varying degrees (often too little to have a meaningful impact). This is like junk skin food.
