We don't publish prices — Amazon changes them constantly and a stale number helps nobody. Tiers below show where each product sits; tap through for the live price.
We started with every one of the 608 skincare products in our catalogue and kept the 7 that genuinely fit "korean skincare serum". Ranking is by real monthly sales volume and review depth, so the top of this list is what people are actually buying rather than whatever carries the fattest commission.
The current pick is the Arencia Vitamin C Booster Shot Serum with Glutathione, Niacinamide and, sitting in the budget tier and holding 4.3 stars across 100 reviews. Options here span budget through mid, and most cluster in the budget tier — useful context, because anything well below that is usually cutting something real.
We don't print prices anywhere on this site. Amazon moves them constantly and a stale figure is worse than none; the tier tells you roughly where a product sits and the link gives you today's number.
Review count matters as much as the star average. A 4.3 across several thousand reviews is a stronger signal than a 4.9 across nine, and we weight it that way.
