Expert Insights

Your Questions, Answered

Discover how K04 - RADIANCE GLOW delivers brightening results and transforms your skincare routine with vitamin C power.

How long does it take to see brightening results with K04 serum?

Most users notice a visible improvement in skin brightness and radiance within 2-3 weeks of consistent daily use. For optimal results in reducing dark spots and achieving an even skin tone, we recommend using K04 - RADIANCE GLOW for at least 4-6 weeks, as this allows the vitamin C to work on pigmentation at the cellular level.

Can I use K04 serum with other skincare products?

Yes, K04 serum integrates beautifully into your existing skincare routine. Apply it to clean skin, morning or evening, before your moisturizer. The lightweight formula absorbs quickly and works harmoniously with other products. Always follow with SPF during the day as vitamin C enhances sun protection.

Is K04 suitable for sensitive and mature skin?

Absolutely. K04 - RADIANCE GLOW is formulated with 2% Natural Vitamin C (Ascorbyl Glucoside), which is gentler than traditional vitamin C while remaining highly effective. Perfect for normal, dry, mature, and all skin types. The formula is vegan, gluten-free, and 99% natural origin. We recommend doing a patch test 24 hours before first use.

What makes the Ferulic Acid in K04 special?

Our formula contains 1% Ferulic Acid, a powerful antioxidant that works synergistically with vitamin C to enhance its effectiveness and stability. Ferulic Acid promotes skin firmness, protects against environmental stressors, and helps prevent premature aging. Together with vitamin C, they create a potent anti-aging and brightening combination.

How should I store my K04 serum to maintain its potency?

Store your K04 - RADIANCE GLOW in a cool, dry place away from direct sunlight to preserve the active vitamin C and other ingredients. Keep the bottle tightly closed when not in use. Avoid storing in the bathroom where humidity fluctuates. Proper storage ensures maximum effectiveness throughout the product's shelf life.
