SIMPLI VERDICT
Should you choose it?
Consider another option if
Niacinamide is new to you, or your face is reactive. Start at 10%, not 20%.
Start-Safe: A few nights a week, nothing else new. If your face stays calm, you can use it more often. Sunscreen every morning.
This is product-level guidance, not a personal routine recommendation. If you already own a suitable product doing this job, you may not need another one.

Common questions
Is 20% better than 10%?
Only if your skin already tolerates niacinamide. More is not kinder.
Will pores shrink?
It is a serum for the look of uneven skin. It will not close a pore.
With retinol?
Not the same night while this is new.
BEFORE YOU BUY
You may already have what you need
A better routine is not always a bigger routine. Check whether this product adds a job your current routine is actually missing.
Keep what works
If the niacinamide you own is already strong enough, finish it. Do not stack two.
You may not need to buy this
Leave it if you have not tried a gentler niacinamide and your skin is easily upset.
