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 soluble active ingredients) or 15g of powder (1/2 sachet) with 45g of liquid (including vegetable oils and oil soluble 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.

Remember to use LESS water if you have added any oils so that you do not exceed the 90g or 45g of liquid or the mask may not set properly. Mix thoroughly to get a homogenous paste. Apply to the skin immediately and leave it to perform its action for 15 minutes. It will rubberise on the skin within a few minutes and once rubberised/set you cannot mix it with water again so work quickly and only use as much as you need. The mask peels off easily once treatment is over. Any excess around the edges can be easily removed by rubbing gently with a damp face cloth. Make sure that the temperature of the water, water soluble active ingredients or hydrolats you use to make the paste is approximately 20C so that the rubberising process will take place more slowly and you can quietly enjoy your treat. If the water is too warm it will speed up the rubberising process and you will have to work very quickly before the mask sets up in the bowl and is unusable.
