One sachet of Peel Off Marine Silt Mask is enough for 1-2 treatments.
Mix 30g (1 sachet) of powder with 90g of liquid (including vegetable oils and oil soluable active ingredients) or 15g of powder (1/2 sachet) with 45g of liquid (including vegetable oils and oil soluable active ingredients).
Do not exceed 5% oily additives as this will not combine fully with the Peel Off Marine Silt Mask powder. Although the mask will set up, albeit more slowly, you will find a layer of un-combined oils on the skin which may prevent the mask from working most efficiently.
Water-soluble ingredients such as AHA, Lupide Peptides, Liftonin, Wu Zhu Extract and Hyaluronic Acid are the most appropriate actives to include in your masks, as well as Glycerol Extracts and Herbal Tinctures.
