Yes, of course it's fine to use vitamin C at π night. And it's just as effective!
But there are a few ingredients that shouldn't be in the same routine with vitamin C.
Here's a guide for your reference. I hope it helps β£οΈ

Yes. But be aware of this
If you use Ascorbic Acid, that will be in a low pH solution.
If you use other products with a higher pH, the vitamin C won't be effective.
Also, the low pH of the Ascorbic Acid solution will counteract th effectivity of peptides and retinol, that need a higher pH to be effective.
So...
Are you using vitamin C derivatives? No problem
Are you using Ascorbic Acid? You shouldn't mix with peptides and retinol.
Many use their peptides an d retinol at night and therefore, opt to use Ascorbic Acid in the morning. Like me

It's ok to use vitamin c both am and pm. I do just that. π It's recommended to use in the morning because it's an antioxidant and makes a good combo with sunscreen. But it's not ineffective when used in the evening.
