The serum was carefully packaged in a sturdy box, with a transparent cap around the dropper, making it a delight to receive with such care. The bottle also has a high-quality feel. Its capacity is 18mL. The serum inside is clear, and when I first touched it, I was amazed at how it felt to use. It has a rich, oily texture, and when I spread it on my skin, it gave off a gentle warmth and a soothing sensation! I couldn't help but exclaim, "Wow..." It was so amazing, it felt like I was getting a beauty treatment. Despite the oily texture, it blends well with my skin without feeling too heavy, and the moisturizing feel is truly wonderful. With continued use, I felt like my skin's texture was improving, and it even had a radiant glow. This is a serum I would recommend especially for mature skin.
