Do you use Niacinamide serum in your skincareroutine?

[Shufflebumnessie]

If so, what benefits does it provide your skin with and have you seen an improvement in your face?
When & how often do you apply it?
Thanks in advance

My teenage DD uses it on any acne prone areas (mostly the T zone). It does seem to make a difference.

I used to use it on my t zone to prevent spots. It is very effective. I used it after cleansing, before moisturising, morning and night.

I use it in the morning - it’s the first thing I use. I think it helps oiliness and spots
