MEDICUBE TXA Niacinamide 15 Serum 30ml is a high-concentration functional serum focusing on "pigment fading + skin tone brightening + oil control", specially developed for dull skin, skin with post-inflammatory hyperpigmentation (PIH), dark spots, or oily skin troubled by excess sebum. It features a "dual-core active formula" with two key ingredients: first, Tranexamic Acid (TXA) —a mild pigment-regulating ingredient that inhibits the transfer of melanin to keratinocytes, effectively fades existing dark spots, sun spots, and post-acne marks (especially red and brown marks), and soothes pigment-related skin redness; second, 15% high-purity Niacinamide —this concentration balances efficacy and mildness, which can regulate keratin metabolism to unclog pores and control oil secretion, improve skin dullness and uneven tone, and enhance the skin’s barrier function to reduce sensitivity. The serum adopts a "lightweight watery texture" that absorbs quickly without greasiness, making it suitable for oily and combination skin, and does not cause a heavy feeling on dry skin. It is free from parabens, artificial fragrances, alcohol, mineral oil, and synthetic colorants, and has passed dermatological testing—suitable for most skin types, including sensitive skin (it is recommended to conduct a patch test before first use for extremely sensitive skin).

1. Tranexamic Acid (TXA): Core pigment-fading ingredient, inhibits melanin transfer, fades dark spots and post-acne marks, and soothes pigment-related redness. 2. 15% Niacinamide (Vitamin B3): High-concentration core ingredient, regulates keratin metabolism to control oil and unclog pores, improves dullness and uneven tone, and strengthens the skin barrier. 3. Panthenol (Provitamin B5): Mild repairing ingredient, relieves potential irritation from high-concentration ingredients, hydrates the skin, and enhances barrier resilience. 4. Sodium Hyaluronate (Hyaluronic Acid): Multi-molecular moisturizing ingredient, replenishes skin moisture while regulating oil and fading pigment, avoiding dryness caused by functional ingredients. 5. Glycyrrhiza Glabra (Licorice) Root Extract: Soothing ingredient, reduces skin sensitivity and redness, balances the mildness of the formula, and maintains skin stability.

1. Use it after cleansing and toning (toner helps balance skin pH and improve serum absorption). 2. Take 2-3 drops of the serum on the palm of your hand, then gently spread it evenly on the face (avoid the eye contour, lip, and other delicate areas). 3. Pat the face with your fingertips in a circular motion until the serum is fully absorbed (do not rub vigorously to prevent skin irritation). 4. Follow up with a moisturizer (and sunscreen during the day): moisturizer locks in the active ingredients of the serum to enhance efficacy; sunscreen is essential because niacinamide and TXA may increase skin sensitivity to UV rays, and sun protection can prevent pigmentation from worsening. 5. Frequency of use: For beginners, use it 2-3 times a week to build skin tolerance; after adaptation, it can be used once a day (it is recommended to use it at night for sensitive skin).
