Hello. I am from Iran. I used olive oil and coconut oil but my soap dries the skin here due to weather conditions the skin dries. Which oil should I add to make the skin soft and moisturized? We don't have cocoa butter or shea butter hereAvailable oils, grape seed, almond, walnut, castor, peanut, pomegranate, sunflower, corn, ostrich, soybean, lavender, mint,. How much can I add to the proportions of olive and coconut to keep the skin dry What is the ideal ratio of olive oil to coconut oil?
