It's fine to use Vitamin C twice daily. If you notice that your skin feels overwhelmed by it, then use it only during the day!
If you're using vitamin C at night, be careful not to mix with some ingredients. Here's a guide for you. I hope it helps โฃ๏ธ

It's fine to use it twice daily given your skin can tolerate it. I only use once a day. Sometimes, every other day when I'm testing another serum and alternate vit c with the serum being tested (there's a study that suggests vit c stays on the skin for up to 72 hours).

Once a day itโs fine bc vitamine C can stay in the skin for 24 hours so itโs still doing itโs job. you will be wasting product

i suggest using it once a day or less.
if youโre using other actives, i would use alternate daily between the actives and vitamin c
