KLAIRS - Freshly Juiced Vitamin Charging Serum 30ml

The 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.

Why It Works

The dual complex leads: 3-O-Ethyl Ascorbic Acid at 10% — a stabilized vitamin C derivative that delivers brightening without pure ascorbic acid’s sting — and niacinamide, which blocks pigment transfer and refines tone from a second angle. Behind them, an antioxidant bench of vitamins E, B2, and B5 supports elasticity for bouncier, firmer-looking skin. The finish is weightless and residue-free, formulated to be extra safe for reactive complexions.

How to Use

Morning 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 Korean sunscreen. It layers naturally over the Vitamin Essence Toner as the line’s power duo.

Who It’s For

Dull 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 Vitamin C for correction phases.

FAQ

Is a vitamin C derivative weaker than pure vitamin C?

Milder 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.

Can I use it with niacinamide products?

It already contains niacinamide — the pairing is the formula’s design, and adding more niacinamide elsewhere in the routine is fine.

Morning or night?

Either. Morning use adds antioxidant support under sunscreen; night use pairs it with repair. Sensitive skin starting out can begin with evenings only.
