| Verdict | 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. | 6.5% retinoid blend + hydroxypinacolone retinoate. Serious A-level work, wrapped in hydration. |
