I'm planning to use a niacinamide serum, but I'm currently using a Vitamin C ampoule as well.
I've heard conflicting information; some say you shouldn't use them together, while others say it's okay.
Does anyone know exactly which one is correct?

While it used to be said that they shouldn't be used together, more recent studies suggest it's okay~ It's safer to use them separately, morning and night.
I should create a routine, splitting it between morning and evening..
I'm using the Oncia Niacinamide Serum separately from the Vitamin C ampoule. ㅋㅋ I use this at night and Vitamin C in the morning, and I haven't had any breakouts, and my skin tone has definitely brightened.
Creating a routine won't be difficult, will it? ㅠㅠ!
