The rail, logged serum by serum

• CeraVe Skin Renewing Vitamin C Serum ($23.86, ★4.5 / 6,708 reviews) — 10% L-ascorbic acid, the most-reviewed option here; L-ascorbic acid is potent but formulation-sensitive to oxidation, so store it away from light and heat.
• Bubble Skincare Day Dream Vitamin C+Niacinamide ($14.97, ★4.6 / 2,359) — pairs vitamin C with niacinamide for tone plus oil-balance, the best-rated option on this list at a mid-range price.
• Good Molecules Daily Brightening Serum ($8.00, ★4.6 / 1,200) — the cheapest entry point with a strong rating, though lower review volume than the CeraVe pick.
• BYOMA Brightening Serum ($15.99, ★4.4 / 1,462) — the lowest-rated of the four, still solidly reviewed; positioned as a barrier-friendly, gentler brightening option.
• Anua Niacinamide 10% + Tranexamic Acid 4% + Arbutin 2% Serum (K-beauty alternative, not ranked above the US rail) — the diagnostic fit for readers whose dullness is genuinely dual-cause (uneven tone and flat texture together); tranexamic acid and arbutin target tone while niacinamide addresses texture and oil, per Anua's own product page.
