Freshly Juiced Vitamin Drop is a water-light vitamin C serum that comes out of a glass pipette and sinks in within seconds. It carries 5% pure ascorbic acid at pH 3.8, the free unmodified form of the vitamin, in a mostly-water base with no oils or silicones. Worn in the morning underneath sunscreen, it works on how bright and how even skin looks.

Klairs calls the delivery system Hybrid Stabilization Technology. The ascorbic acid sits with centella asiatica extract, yuzu fruit extract and grapefruit extract, plus sodium hyaluronate to hold water at the surface. The 5% level is a deliberate choice rather than a compromise: it is pitched as the approachable end of the vitamin C range, so the drop stays wearable day after day.

It suits anyone starting vitamin C for the first time, or coming back to it after a harsher bottle went unused. Look for the flat cast lifting, tone reading more even from cheek to jaw and the surface feeling less grainy over a few weeks. The finish is dry and close to matte, so nothing rolls or pills under SPF.

One honest caveat sits in the ingredient list. This is not a fragrance-free formula: sweet orange oil and lavender oil are both present and limonene is declared. Pure ascorbic acid is also naturally unstable, and the liquid drifts from clear towards pale gold as it ages. Keep the bottle boxed somewhere cold and dark, and retire it once the colour turns deep orange.
