| Verdict | Eight dollars. Two molecular weights of hyaluronic acid plus a crosspolymer for sustained release. Panthenol for barrier repair. Eight ingredients total. Good Molecules strips the hydrating serum category to its functional minimum and charges accordingly. The formula doesn't do anything The Ordinary's version doesn't — but Good Molecules consistently delivers cleaner textures and better absorption. The best under-$10 hyaluronic acid serum on the American market. | The US cosmetic-derm world's post-procedure gold standard. TNS — Tissue Nutrient Solution, a growth-factor complex derived from human fibroblast conditioned media — paired with signal peptides and barrier support. Clinical data on photoaging is published and serious. $295 is genuinely expensive, but the 4–6 week post-Fraxel case is exactly what this product was built for. |
