Thinest to Thickest
'What order to I use my products?' is a question I am often asked. The best way to remember it is 'Thinest to Thickest'.
After cleansing the skin, you would begin layering your products with the thinest product, a serum first. When applying make sure that the first products onto the skin are water based and not oil. Oil will not penetrate water so these should go on last before your final cream.
Serums are packed with active ingredients and are made with smaller molecules than those in a cream. A simple analogy for you is; take two glasses filled with crushed ice. Two jugs, one filled with skimmed milk and one filled with double cream. Pour the the two jugs together over the ice and you will see that the skimmed milk will go straight to the bottom of the glass, whilst the double cream will work its way down. This is what is happening with your products.
I hope this helps.
