Medicube — TXA Niacinamide Capsule Cream 55g

This cream embodies a dual formulation approach—depigmenting active ingredients AND the galenic format. The bi-component capsule/gel format solves a common problem: TXA and brightening active ingredients formulated in a classic cream base lose effectiveness due to interactions with other components and oxidation. By encapsulating the active ingredients until the moment of mixing, the manufacturer protects their integrity. The quadruple depigmenting mechanism is consistent and well-documented in the literature: 1. TXA (Tranexamic Acid): inhibits melanocyte-keratinocyte communication → reduces stimulation of melanogenesis. 2. Niacinamide 5% (50,000 ppm): inhibits the transfer of melanosomes to keratinocytes. 3. Alpha-Arbutin: direct tyrosinase inhibitor. 4. 3-O-Ethyl Ascorbic Acid: stable vitamin C derivative → tyrosinase inhibition + antioxidation. Glutathione and Ferulic Acid complement the antioxidant action. 5 forms of HA (Hydroxypropyl Trimonium Hyaluronate, Sodium Acetylated HA, HA, HA Crosspolymer, Hydrolyzed Sodium HA) ensure multi-level hydration. Points of caution: CYMBOPOGON CITRATUS LEAF OIL (lemongrass, contains Citral — potential EU allergen) and ILLICIUM VERUM (star anise) are present. No "PARFUM/FRAGRANCE" explicitly declared on the packaging. Verify if CITRAL is listed individually on the physical packaging. As a precaution, pregnancy_conditional. The Sephora clinical test (Global Institute of Dermatological Sciences) is robust: +46% radiance and +41% hydration after a single use — data measured by an independent organization (not self-assessment). This is the most robust clinical data profile of Medicube products in this catalog.
