Is my formulation including too much or would this be ok?
HI there! I am a complete newbie based in the UK and have been reading up on as much as I can about formulating my own face cream.
I created a formula on paper and was wondering if the formulation looked correct and if I was missing anything or perhaps even clashing with ingredients before I attempted to create it.
I have checked the usage rates suggested by the supplier and have not exceeded any so some ingredients I may not be able to increase the percentage of.
I am looking for a gel cream consistency that isn’t too oily or too heavy as it would be a hydrating cream that sinks into the skin fairly quickly that I would use in the morning before my sunscreen.
Thank you all!
