Paula's Choice Skincare 10% Niacinamide Booster

This stuff is highly rated on Paula's Choice, but I have insanely sensitive skin so unfortunately it didn't work out for me. Only used 3-4 times. "10% Niacinamide serum for improving uneven skin tone and refining the appearance of pore size, skin texture and fine lines" Product description: https://www.paulaschoice.com/10pct-niacinamide-booster/798.html
