1. After cleansing and toning, dispense 1-2 pumps of serum onto your fingertips. 2. Gently pat and press the serum onto your face and neck, avoiding the eye area. 3. Follow with your preferred moisturizer. For best results, use both morning and night. Timeline Expectations: Week 1: Skin feels noticeably softer and more hydrated. Week 2-3: Dullness begins to fade; skin tone looks more even and luminous. Week 4+: Consistent use helps visibly reduce the appearance of dark spots and prevents new ones from forming, for a clearer, brighter complexion.

Kose, founded in 1946 in Tokyo, created Moisture Mild White VC C100 Essence to answer a specific need: a gentle yet potent brightening serum for skin stressed by modern life. Their researchers focused on a single, high-stability form of Vitamin C (Ascorbyl Glucoside) at a precise 100mg concentration, proven to be effective without irritation. Every batch is produced in Kose's own GMP-certified Japanese facilities, adhering to strict pharmaceutical-grade standards for medicated cosmetics (quasi-drugs). This dedication to a simple, targeted formula has made it a top-ranked serum in Japan for over a decade, trusted by millions for its reliable, no-fuss performance.

The Kose Moisture Mild White VC C100 Essence - Medicated Brightening Serum 20ml is formulated with a blend of key ingredients designed to target skin brightening and hydration. At its core, it contains Ascorbic Acid (Vitamin C), a potent antioxidant that inhibits melanin production to reduce dark spots and uneven skin tone, while also stimulating collagen synthesis for improved skin elasticity and firmness. This is complemented by Tranexamic Acid, which further suppresses melanin activity to address hyperpigmentation and post-inflammatory marks, enhancing overall clarity. The formula includes Sodium Hyaluronate, a humectant that attracts and retains moisture in the skin, ensuring deep hydration and a plump, smooth texture. Additionally, it features Dipotassium Glycyrrhizate, derived from licorice root, which soothes inflammation and reduces redness, making it suitable for sensitive skin. Other components like Butylene Glycol and Glycerin act as emollients and moisturizers, improving skin barrier function and preventing dryness. Together, these ingredients work synergistically to deliver a medicated brightening effect, promoting a radiant, even complexion with reduced pigmentation and enhanced moisture retention, ideal for daily use in a skincare routine aimed at achieving luminous, healthy-looking skin.
