The Derma Plus (a brand of Izabel Health Care, Bangladesh) discloses the following active ingredients on its own official product page: Tranexamic Acid 2%, Alpha Arbutin 1.5%, Niacinamide 3%, and Panthenol 1%. Note: one Bangladesh retailer's listing for this same product additionally names Glutathione and Hyaluronic Acid as key actives, but neither ingredient appears on the brand's own official ingredients description. Following source-priority guidance (official brand site over third-party retailer listings), we have presented only the brand's own confirmed actives here and flagged Glutathione and Hyaluronic Acid as unconfirmed for this specific SKU -- this discrepancy could reflect outdated retailer copy, a reformulation, or retailer over-claiming, and was not resolved by our research. A complete, ordered full INCI list beyond these named actives was not found from any source.
A face serum formulated at a 5.0-5.5 pH range, combining Tranexamic Acid, Alpha Arbutin, Niacinamide, and Panthenol, positioned to address dark spots and acne scars, described by the brand as a "Fragrance-Free Formula" with no added essential oils or synthetic scent.
Tranexamic Acid and Alpha Arbutin are both ingredients commonly used to help address hyperpigmentation and support a more even skin tone. Niacinamide helps regulate excess oil production, and Panthenol provides hydration without a heavy or greasy texture. The brand markets an estimated 4-6 week timeframe for visible dark-spot fading, though individual results vary and this should not be treated as a guaranteed outcome.
Marketed toward those with dark spots, acne scars, or uneven skin tone, particularly those with oily skin given the Niacinamide content. Individuals with known sensitivity to Tranexamic Acid or Alpha Arbutin should patch test first or consult a dermatologist before regular use.
Apply 2-3 drops in the evening to clean, dry skin, following with a moisturizer. The brand advises using sunscreen during the day when using this product, as is standard practice with brightening/pigmentation-focused actives.
Store in a cool, dry place away from direct sunlight. Keep out of reach of children. Discontinue use if irritation, redness, or an allergic reaction occurs, and consult a doctor if symptoms persist. Apply sunscreen during the day while using this product.
