Vitamin E is not recommended. 0.5% because it is sticky on the skin even if the skin is dry And the use at a high rate does not have any research showing that it can give better results than the use of 0.1-0.5%. 3. glycerin soluble in water, insoluble in oil Recipes won't mix. Please glycerin 4. The recipe uses Butter, Many types of oils, although oils and butters They can usually dissolve together. But there is a chance to separate the layers.
