This serum combines 20% niacinamide (vitamin B3) with 1% hyaluronic acid, green tea extract, and beta-glucan in a water-based formula designed for daily facial use. Niacinamide at this concentration supports the appearance of reduced pore size and a more even skin tone by helping to regulate sebum activity and promote surface cell turnover. Hyaluronic acid provides lightweight hydration to maintain moisture balance without clogging pores. Green tea extract offers antioxidant properties that may help protect the skin from environmental stressors, while beta-glucan contributes to soothing and moisturizing effects. The formula is free from artificial fragrances, essential oils, and drying alcohols, making it suitable for combination, oily, and normal skin types. Those with sensitive skin are advised to patch test due to the 20% niacinamide content, which is higher than standard formulations. The serum has a thin, watery texture that absorbs quickly without leaving a sticky or greasy residue. It can be applied after cleansing and before moisturizer, both in the morning and evening. Pricing positions it as a budget-friendly option within the Korean skincare segment, offering a high-concentration active ingredient at an accessible cost. This product does not claim to eliminate fine lines or permanently minimize pores; rather, it aims to support overall skin texture and tone through consistent use. As with any targeted serum, results depend on individual skin condition and adherence to a complete skincare routine. The packaging is a dropper bottle designed to dispense the correct amount and preserve ingredient stability. Storage in a cool, dry place away from direct sunlight is recommended.
