| Verdict | iS Clinical's hydration-and-calming serum — sodium hyaluronate + Centella asiatica triple-acid complex (Asiaticoside + Asiatic Acid + Madecassic Acid) + pantothenic acid (B5) + a touch of menthol for the cooling sensation. The Centella triple-acid is the differentiator: most Centella products use the whole-extract; iS Clinical isolates the three active triterpenes for a clinical-strength anti-inflammatory effect. Layer over Active Serum to buffer the multi-acid sting, or use solo for reactive/irritated skin. | 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. |
