Novexpert — Express Blemish Control

Novexpert's Stop Bouton Express is a targeted localized treatment designed to accelerate the resolution of nascent or established imperfections. Its formula is deliberately minimalist (10 ingredients) and concentrated. The Trio-Zinc (ZINC PCA + ZINC GLUCONATE + ZINC LACTATE) is the same complex found in the Foaming Jelly and Booster Serum, but in this localized treatment, the concentration is likely higher (positions 6, 7, 8 in a 10-ingredient INCI list). ALCOHOL DENAT. in second position (after water) is characteristic of localized treatments: denatured alcohol creates a rapid drying effect on the imperfection and optimizes active ingredient penetration. Lactic acid (LACTIC ACID, 3rd position) provides a local exfoliating action that promotes the resolution of imperfections on the surface. Succinic acid complements the purifying action. Pharmacist vigilance points: (1) ALCOHOL DENAT. and LACTIC ACID in high INCI positions → cautious approach during pregnancy despite the manufacturer's claimed compatibility for localized use. (2) The treatment must be applied to BARE SKIN only, never on an open wound or lesion. (3) Avoid the eye contour and mucous membranes. (4) The manufacturer's in vitro data on melanin (-73% synthesis, -62% export) appears to relate to active ingredients in a cellular model — not measurements on the finished product. This treatment is complementary, not a substitute for medical treatment in cases of extensive or infected lesions. If in doubt, refer for a dermatological consultation.
