I don’t know why anyone would buy a scrub, when there are so very many different ones to be made with simple kitchen ingredients. I’m working on a list of basic ingredients and their properties, but for now a note on the carrier oil often mentioned below: there are several suitable oils that can be used for this, so it’s up to personal preference and skin type. The simplest may be olive oil, rich in antioxidants, which is absorbed well and may already be in your pantry. Sweet almond oil is another nourishing and versatile one that won’t leave an oil film on the skin.
While coconut oil is used a lot for the consistency it creates, it’s not indispensable: it can be replaced with half the amount of carrier oil. The scrub will have a less pretty appearance, but be just as effective.
