In short: Niacinamide is the amide form of vitamin B3; formulas use it for visible pores, sebum and the look of skin tone. In the s'hevec range, the highest concentration is 10%, in the Hi Girls Bye Pores serum; other products contain between 2% and 5%, or include it without a stated concentration. You can use more than one niacinamide product in the same routine, but add them one at a time.
How much is in each product?
Can they be used together?
Yes; add the products to your routine one at a time. If you get redness when using Hi Girls Bye Pores together with Any Time Of Day, use the serum less often. Slyc-Alright does not contain niacinamide, so it can be used on the same evening as Hi Girls Bye Pores without doubling up.
What not to expect
A high niacinamide concentration can cause temporary redness on sensitive skin. A serum does not make pores smaller but helps them look less visible. Products focused on pores are in the Visible Pores collection.
