There is nothing simpler or more beneficial than preparing an on-the-spot mask or scrub, which will often be more naturally efficient than many a commercial cosmetic formulation. A spoonful of powder, a few drops of oil, a little ionized or shungite water in the palm or a bowl, and there you have it: a treatment that is most closely suited to the needs of your skin and hair, to the day’s weather, etc. Some fine powders are also efficient beauty adjuvants in the bath.
