1. Start with your usual cleansed and moisturized face. 2. Apply a pearl-sized amount (about 0.3g) to your fingertips. 3. Gently smooth over your entire face, focusing on areas where you want a luminous effect. 4. Allow 60 seconds for the zero-gravity texture to set and create a smooth canvas. 5. Apply your foundation or wear it alone for a natural glow. **Timeline Expectations**: Week 1: You'll notice an immediate 'smoother canvas' and a subtle, healthy luminosity that makes skin look rested. Week 2-3: With consistent use, the brightening berry blend works cumulatively. Skin tone appears more even, and the primer's effect lasts longer throughout the day. Week 4+: This is where the skin-optimizing benefits solidify. Your complexion maintains a consistent, natural-looking radiance with less primer needed, as your skin's own clarity is enhanced.

Kose Blend Berry Zero G Luminous Effector was born from a simple observation in Japanese beauty labs: modern life is tough on skin. Between blue light, pollution, and daily stress, achieving a natural glow felt like a constant battle. Kose researchers, operating under Japan's strict Pharmaceutical Affairs Law, developed this primer not as a cover-up, but as a skin optimizer. They combined a patented blend of 4 Japanese berries with a unique zero-gravity texture technology, creating a formula that works *with* your skin's rhythm. Every batch is produced in a GMP-certified facility in Japan, ensuring pharmaceutical-grade purity. It quickly became a top-ranked primer in Japan, praised for creating a 'lit-from-within' look that lasts all day, proving that radiant skin isn't about hiding, but about enhancing your skin's natural potential.

The Kose Blend Berry Zero G Luminous Effector - Brightening Face Primer 25g contains a carefully formulated blend of ingredients designed to enhance skin radiance and provide a smooth base for makeup application. Key ingredients include silica, which acts as a light-diffusing agent to create a soft-focus effect and minimize the appearance of pores and fine lines, thereby imparting a luminous finish. Cyclopentasiloxane and dimethicone are included as silicone-based emollients that offer a silky texture, ensuring easy spreadability and long-lasting hydration while forming a breathable barrier to lock in moisture. Niacinamide (Vitamin B3) serves as a brightening component, helping to reduce hyperpigmentation and improve skin tone uniformity through its anti-inflammatory properties. Botanical extracts such as raspberry fruit extract and strawberry fruit extract provide antioxidant benefits, protecting the skin from environmental stressors and contributing to a healthy glow. Additionally, ethylhexyl methoxycinnamate offers UV protection to shield against sun damage, while various polymers enhance the primer's adherence to the skin, ensuring makeup longevity. This combination results in a product that not only primes the skin for flawless makeup application but also delivers skincare benefits like hydration, brightness, and protection, making it suitable for achieving a radiant complexion.
