The exact duration depends on how much you apply and how many areas of the face you treat, but most users find the bottle lasts well over a month of consistent use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eShould I refrigerate the serum after opening?\u003c\/h3\u003e\n\u003cp\u003eYes, refrigeration after opening is strongly recommended. Vitamin C serums are sensitive to heat, light, and air, and storing the bottle in the fridge helps preserve the 23% pure Ascorbic Acid potency, extends shelf life, and provides a refreshing, cooling sensation during application.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs this serum compatible with retinol, AHA, or BHA products?\u003c\/h3\u003e\n\u003cp\u003eIt can be used alongside most actives, but layering order matters. Apply Vitamin C in the morning and stronger exfoliants like retinol, AHA, or BHA in the evening to avoid potential irritation. If you have sensitive skin, alternate days when first introducing the serum and monitor how your skin responds.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan I use this serum with my current moisturizer and sunscreen?\u003c\/h3\u003e\n\u003cp\u003eYes, the lightweight, non-sticky finish layers easily under most moisturizers and sunscreens. Apply the serum first, allow it to absorb for a minute, then follow with your moisturizer and SPF 30+ during the day. The serum is designed to complement rather than replace your existing routine.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat is included in the box when I order the serum?\u003c\/h3\u003e\n\u003cp\u003eYour order includes one 0.7oz bottle of COSRX Advanced Pure Vitamin C 23% Serum with the drop applicator attached. No additional accessories, tools, or instructions are included, so you can begin using the product immediately after unboxing. The bottle is ready to use straight from the package.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs this serum safe for daily long-term use?\u003c\/h3\u003e\n\u003cp\u003eYes, the formula is designed for daily use and is suitable for all skin types. The upgraded scent-free version is gentler on the skin than the original, and the lightweight finish makes daily application comfortable. As with any active serum, patch testing first is recommended if you have particularly sensitive skin.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWill this serum cause irritation, redness, or breakouts?\u003c\/h3\u003e\n\u003cp\u003eMost users tolerate the formula well because it is scent-free and lightweight. However, high-concentration Vitamin C can cause mild tingling during the first few uses as your skin adjusts. If irritation persists, reduce application to every other day and gradually build up to daily use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat is the difference between a Vitamin C serum and a Vitamin C cream?\u003c\/h3\u003e\n\u003cp\u003eA Vitamin C serum delivers a high concentration of active Ascorbic Acid in a lightweight liquid format that penetrates quickly and absorbs efficiently into the skin. A Vitamin C cream typically has a lower concentration of actives mixed with emollients and is heavier in texture. Serums are preferred when you want maximum brightening and anti-aging efficacy, while creams are better for added hydration.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Knacklos","offers":[{"title":"Default","offer_id":43562294149210,"sku":"AX1B0FWQGLTQV","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/7969\/9034\/files\/23-pure-vitamin-c-ascorbic-acid-for-brightening-and-anti-agi.jpg?v=1782558247","url":"https:\/\/knacklos.myshopify.com\/products\/cosrx-vitamin-c-23-serum-daily-brightening-ritual-for-women-morning-skincare-step-for-bathroom-vanity","provider":"Knacklos","version":"1.0","type":"link"}
