Ruruberry - pparuhwaktu review for 10% Niacinamide + Zinc

This serum has a fairly thick texture without any fragrance. When I spreads, it feels slippery and a bit tacky. Once absorbed, it's not sticky at all and there is a moist feeling on the skin. Surprisingly, I also feel that this serum makes the serum afterward absorb faster and work more optimally.. And when I read it again, I found that the title was indeed 'booster drop', so the skincare steps afterward felt even more 'boom'! So far, it really makes the skin feel brighter, smoother and plumpy.
