Vita B3 VS Dark Spor Correcting Serum

They both contain hyaluronic acid and niacinamide, but the Tia'm Vita B3 Source also contains arbutin. The Axis-Y serum contains 5% niacinamide and rice extract, while the Tia'm Vita B3 Source contains 10% niacinamide and 2% arbutin.They're both likely to be good for fighting acne, brightening skin, sensitive skin, oily skin, reducing pores and dark spots. Overusing niacinamide or using high percentage products can cause irritation and breakouts. Follow the instructions on one bottle and then when one finishes our start on the other, that’s what I would do anyways. :) hope that helps!

Both contains niacinamide but tiam contains a higher percentage (10%) and axis-y contains 5%. I would use them in different routines morning-night or on alternative days.

Use them every other day. One has 5% niacinamide and the other has 10%. Both at the same time is too much.
