Why $25 is the sweet spot
This is typically where retinol serum shopping shifts from "cheapest option" to "best value" -- established brands start showing up alongside no-names, and build quality improves noticeably without a premium markup. It's the range most reviewers land on for everyday use rather than occasional/backup use. Compare at least two listings before buying: look at what review complaints mention (not just the star average), and confirm the seller ships from or is fulfilled by Amazon.
