{"product_id":"klairs-freshly-juiced-vitamin-charging-serum-30ml","title":"KLAIRS - Freshly Juiced Vitamin Charging Serum 30ml","description":"\u003cp\u003eThe Vitamin Charging Serum is the strongest sentence in KLAIRS’ gentle brightening argument: a 10% vitamin C derivative paired with niacinamide, in a texture so light and non-oily that even sensitive skin can wear it daily. It targets the whole radiance problem at once — uneven tone, pigmentation, and the slack dullness of tired skin — without asking your face to endure anything.\u003c\/p\u003e\u003ch2\u003eWhy It Works\u003c\/h2\u003e\u003cp\u003eThe dual complex leads: \u003cstrong\u003e3-O-Ethyl Ascorbic Acid at 10%\u003c\/strong\u003e — a stabilized vitamin C derivative that delivers brightening without pure ascorbic acid’s sting — and \u003cstrong\u003eniacinamide\u003c\/strong\u003e, which blocks pigment transfer and refines tone from a second angle. Behind them, an antioxidant bench of vitamins \u003cstrong\u003eE, B2, and B5\u003c\/strong\u003e supports elasticity for bouncier, firmer-looking skin. The finish is weightless and residue-free, formulated to be extra safe for reactive complexions.\u003c\/p\u003e\u003ch2\u003eHow to Use\u003c\/h2\u003e\u003cp\u003eMorning or evening (or both) after toner: a few drops pressed over the face, then moisturizer. Morning use pairs beautifully with sunscreen, which vitamin C quietly reinforces — and which protects the brightening you are building; see \u003ca href=\"\/fr\/collections\/korean-sunscreen\"\u003eKorean sunscreen\u003c\/a\u003e. It layers naturally over the Vitamin Essence Toner as the line’s power duo.\u003c\/p\u003e\u003ch2\u003eWho It’s For\u003c\/h2\u003e\u003cp\u003eDull and uneven skin that wants visible brightening at a strength it can actually sustain — especially anyone who bought a strong ascorbic serum once and abandoned it by week two. High-tolerance skin can treat it as the comfortable daily driver, with heavier artillery in \u003ca href=\"\/fr\/collections\/vitamin-c\"\u003eVitamin C\u003c\/a\u003e for correction phases.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eIs a vitamin C derivative weaker than pure vitamin C?\u003c\/h3\u003e\u003cp\u003eMilder on skin, yes — that is the point. 3-O-Ethyl Ascorbic Acid trades some raw intensity for stability and daily tolerability, and at 10% with niacinamide alongside, consistent use delivers what abandoned stronger serums never do.\u003c\/p\u003e\u003ch3\u003eCan I use it with niacinamide products?\u003c\/h3\u003e\u003cp\u003eIt already contains niacinamide — the pairing is the formula’s design, and adding more niacinamide elsewhere in the routine is fine.\u003c\/p\u003e\u003ch3\u003eMorning or night?\u003c\/h3\u003e\u003cp\u003eEither. Morning use adds antioxidant support under sunscreen; night use pairs it with repair.
