| Verdict | iS Clinical's hero product and the formulation that built the brand. A botanical multi-acid serum: mandelic acid (gentle AHA, suits sensitive skin), salicylic acid (BHA, acne-targeted), L-ascorbic acid (vitamin C, brightening), arbutin (tyrosinase inhibitor for pigmentation), bilberry + sugar cane + lemon + orange + maple extracts (multi-source AHA/BHA). The breadth is the differentiator: this serum addresses acne, hyperpigmentation, and early aging in a single application — which is why dermatologist offices stock it as the all-in-one cosmeceutical entry point. | 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. |
