You can expect to see initial brightening and improved skin radiance within 2-3 weeks of consistent daily use. For more dramatic results like fading dark spots and evening skin tone, most users see significant improvements after 6-8 weeks. The collagen-boosting anti-aging effects typically become noticeable after 3 months of regular application. For best results, use morning and evening on clean skin, followed by moisturizer and SPF during the day.
Yes, our pH-balanced 10% Vitamin C serum is formulated to work harmoniously with other skincare actives. It pairs exceptionally well with niacinamide for enhanced pore refining and oil control - try our Vitamin C + Niacinamide Duo for optimal results. You can also use it with retinol (alternate nights), hyaluronic acid, and peptides. Always apply Vitamin C first, allow full absorption, then layer other products.
Absolutely! Our clinical-grade formula is specifically designed for sensitive skin with a gentle 10% L-ascorbic acid concentration that delivers maximum benefits without irritation. Unlike harsh vitamin C serums that can cause redness or peeling, our Korean-formulated treatment is pH-balanced and includes soothing ingredients. Start with every-other-day application for the first week, then gradually increase to daily use as your skin builds tolerance. It's non-comedogenic and suitable for all skin types, including acne-prone skin.
Korean clinical skincare combines advanced scientific research with traditional beauty wisdom, focusing on gentle yet highly effective formulations. Our vitamin C serum uses stabilized L-ascorbic acid that maintains potency longer than unstable forms found in many Western brands. The Korean approach emphasizes working with your skin's natural barrier rather than disrupting it, resulting in better absorption, less irritation, and more consistent results. Additionally, our formula includes complementary ingredients that enhance vitamin C stability and bioavailability, ensuring you get maximum benefits from every drop.
