1. Start with your clean, moisturized face. 2. Apply a pearl-sized amount of the primer. Gently smooth it over your entire face, focusing on areas where makeup tends to fade. 3. Wait 1-2 minutes for it to set into a smooth, non-sticky base. 4. Apply your foundation and makeup as usual. For best sun protection, reapply every 2 hours if you are outdoors. Timeline Expectations: Week 1: You'll notice your makeup applies more smoothly and has a subtle, healthy glow. Week 2-3: With consistent use, your makeup stays put longer through daily activities. Your skin may feel more protected and look more even. Week 4+: The berry extracts help support your skin's natural radiance. Your complexion looks brighter, and the primer becomes a trusted part of your routine for lasting, protected makeup.

Kose was founded in 1946 in Tokyo, Japan, by a pharmacist who believed skincare should be simple, effective, and trustworthy. This formula was created for modern life, where daily stress and environmental factors can make skin look dull and tired. We selected a unique blend of berry extracts and a patented UV filter system because research showed they work together to protect and brighten skin. Every batch is made in a Japanese factory with GMP certification, the same strict standard used for pharmaceuticals. It's been tested for safety and performance. This product quickly became a top-ranked primer in Japan for its dual-action formula, trusted by users who want their makeup to last while getting serious sun protection.

The Kose Blend Berry Lasting Base UV SPF 50 - Radiant Primer & Sunscreen incorporates a sophisticated blend of ingredients designed to provide comprehensive sun protection, skin priming, and aesthetic benefits. Key components include zinc oxide and titanium dioxide, which are mineral-based physical sunscreens that offer broad-spectrum UV protection by reflecting and scattering UVA and UVB rays, making them suitable for sensitive skin due to their gentle nature. Ethylhexyl methoxycinnamate (octinoxate) and bis-ethylhexyloxyphenol methoxyphenyl triazine (Tinosorb S) enhance the SPF efficacy through chemical filtration, ensuring long-lasting defense against photoaging and sun damage. The formulation also features cyclopentasiloxane and dimethicone, silicone derivatives that create a smooth, velvety base by filling in fine lines and pores, thereby improving makeup adherence and longevity while imparting a non-greasy, matte finish. Additionally, berry extracts, likely from the blend referenced in the product name, contribute antioxidants such as vitamins and polyphenols to neutralize free radicals, promote skin radiance, and provide mild hydration. Hyaluronic acid or its derivatives may be included to attract and retain moisture, supporting skin plumpness and barrier function. Overall, these ingredients work synergistically to deliver high-level sun protection, a flawless priming effect, and skincare benefits like hydration and antioxidant support, catering to users seeking a multifunctional product for daily wear.
