text: You can use upto 3% but you need to check the ifra for the safe usage amount in wash off products! So if something is over 3% on the category it used to be 9a but I think it's been changed and not sure what too but they will have a chart and it will state what each category covers. But if it says 0.5% is maximum usage that's the most you can use in wash off products! Always always weigh them in grams and don't use pipettes treasure them in ml as they arnt even close to accurate and arnt intended to be it's like saying you measure wax by the measurements on a jug! It's simply not something you should be doing let alone advising someone else should do 🙄🙄
  
  Please don't take advice from someone who doesn't have a clue about cosmetic laws what fiona is telling you is not only inaccurate, its not nessicarly safe and she gifts them out without an assessment so what's she's doing is also illegal please don't take advice from someone who has zero care for the law or safety!
