I've read that when combining products, it's best to go from thin to thick when it comes to consistency EXCEPT for products containing actives such as vitamin c and retinol. When you use serums containing actives, it is best to put them first regardless of consistency because you want it to be absorbed by the skin first. So I think in your case, it's best to put vitamin c first before putting niacinamide in case you want to layer your products :)

that’s interesting! I did not know that! I always thought you had to apply from thin to thick regardless of the type of product. thanks for the info!

i would personally use vitamín C in the morning and niacinamide in the evening but if you want to use them both in one routine, I would start with vitamin C 😊

I totally get that which is why I try to minimalise my skincare routine. Would be lost trying to combine All those serums in one routine 🤣🙈

I use them together in one routine without any problems, and I apply Vitamin C first, Niacinamide second.

I've read about how to combining this two products. Simply using the Vitamine C in the morning then apply niacinamide at night. If you find some allergic signs, please stop using this combining..
