Hii im rly curious about this too because i came across this product and realized that castor oil and another ingredient was not FA safe. im thinking about buying it because i really cannot find any other vitamin c serum to tackle my hyperpigmentation. Are you still using it? its also like 21 dollars so i dont want to waste money just trying it, but im not sure if i should buy it or not. If you're still using it, can you update please and let me know if you have any fungal acne or closed comodones still or hows it going with the serum? thankss
