It might be a bit too much niacinamide in one routine, even 5% would be enough. Use one AM and the other PM?

the boots ones has niacinamide too as its ingredient. i dunno if the concentration high too. but i personally will use these 2 in the different routine, because to niacinamide already has high concentration.

you shouldn’t use two products with niacinamide in together, I would recommend you use one in the am & another in the pm! 💗
