The verdict

Which should you choose?

Niacinamide Serum goes further with Niacinamide, which Hyaluronic Acid Serum doesn't have. If you only need Hyaluronic Acid, Hyaluronic Acid Serum covers it; if you want Niacinamide as well, choose Niacinamide Serum. Hyaluronic Acid Serum is the better fit for dehydration, dryness and dullness; Niacinamide Serum for oiliness, congestion and dark spots. Both sit in the Budget price tier.
