This duo is formulated to work as a complementary pair. A popular approach is to use the Vitamin C serum in the morning (for its brightening and antioxidant properties) and the Retinol serum at night (to support skin renewal while you sleep). Always follow with a broad-spectrum SPF during the day when using Retinol.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the HISENRAIN Serum Duo suitable for sensitive skin?\u003c\/h4\u003e\n\u003cp\u003eA: The formula is designed for all skin types, including sensitive skin. However, if your skin tends to react to new products, we recommend performing a patch test on a small area of skin before full application. If redness or irritation occurs, discontinue use and consult a skincare professional.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long before I see visible results from this serum duo?\u003c\/h4\u003e\n\u003cp\u003eA: Skincare results vary by individual, but consistent daily use is key. Many users begin to notice improved hydration and a more even, radiant-looking complexion within 2–4 weeks, with more noticeable improvements in skin texture and firmness appearing over 6–8 weeks of regular use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this serum combo suitable for men as well as women?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
