Face serum causing breakouts
I formulated a water based face serum , ph 5.4. I used it on my skin and gave it to my cousin too. After 2 or 3 days of application we both noticed change in skintone. Both got really tanned, dark,had some breakouts. We apply sunscreen daily and never had any issue with other water based serums. Dont know where the formulation is going wrong. Need help?
Ingredients : Niacinamide 6%, glycerine 4%, alpha arbutin 1%, HA .20%,D panthenol 0.5%, licorice extract 2%, edta .03%, citric acid 0.05% and lactic acid for buffer, distilled water , iscaguard peg 1 %
Do you think lactic acid or citric acid maybe the issue ?
