1. Start with your regular moisturizer and let it fully absorb. 2. Apply a pea-sized amount of primer to your fingertips. 3. Gently smooth and press it over your entire face, focusing on the T-zone and areas prone to shine. 4. Wait 60 seconds for the primer to set into a smooth, velvety matte finish before applying foundation. For best results, use as the final step in your skincare routine, right before makeup. Timeline Expectations: Week 1: Notice an immediate smoother canvas and less foundation settling into lines. Week 2-3: Experience significantly longer wear time; makeup stays put through daily commutes and work hours with minimal midday shine. Week 4+: Enjoy consistent, reliable oil control. Your foundation looks freshly applied for hours, reducing the need for touch-ups and powder.

Born from Kose's 70+ years of Japanese skincare research, this primer was created to solve a modern problem: makeup that melts away in today's stressful, fast-paced life. Kose scientists in Tokyo developed this formula after analyzing over 10,000 customer feedback points on foundation longevity. They selected a unique polymer blend, certified by Japan's rigorous GMP standards, to create a base that works *with* your skin, not against it. The result isn't just another primer; it's a precision tool for makeup that lasts. It's now a top-ranked base product in Japan, trusted for its no-nonsense approach to all-day wear.

The Kose Make Keep Primer - Long-Lasting Matte Finish & Oil Control Base is formulated with a blend of key ingredients designed to enhance makeup longevity and manage sebum production. Cyclopentasiloxane and dimethicone are included as silicone-based emollients that create a smooth, velvety base by filling in fine lines and pores, which helps to blur imperfections and provide a uniform canvas for foundation application. These ingredients also contribute to the primer's lightweight texture and facilitate easy spreadability. To address oil control, the product incorporates silica and talc, which are effective absorbent agents that work to mattify the skin by soaking up excess sebum throughout the day, thereby reducing shine and preventing makeup from sliding off. Additionally, the formulation contains ethylhexyl palmitate, a skin-conditioning ester that imparts a soft, non-greasy feel while improving product adherence to the skin. The inclusion of butylene glycol acts as a humectant to maintain skin hydration without adding oiliness, ensuring that the matte finish does not compromise skin comfort. Collectively, these ingredients synergize to deliver a long-lasting, shine-free base that minimizes the need for touch-ups, making it particularly beneficial for individuals with combination to oily skin types seeking enhanced makeup wear and a refined, matte complexion.
