Is the cheaper The Ordinary serum as good as the pricier La Roche-Posay or ALASTIN options?

By verified-purchase ratings, The Ordinary's Hyaluronic Acid 2% + B5 holds a 4.7 average across more than 37,000 reviews at under $10, which is one of the strongest value signals in this group. The La Roche-Posay Hyalu B5 (4.6, 35,000+ reviews) adds vitamin B5 and madecassoside and is widely bought, while the ALASTIN serum costs roughly ten times as much with a far smaller review base. Higher price does not clearly buy higher buyer satisfaction in this pool.
