Features

10% daily-strength choice: NA10 combines 10% niacinamide with 2% PCA zinc and 2% panthenol for shoppers starting with the series or preferring the lower concentration.

20% concentrated choice: NA20 pairs 20% niacinamide with 4% PCA zinc for experienced users seeking the stronger option.

Hydration support: Both formulas include four forms of hyaluronic acid alongside supporting skincare ingredients.

Clear formula selection: The strength and PCA-zinc percentage are stated so customers can choose by routine experience instead of guessing.

30mL dropper bottles: Each strength comes in a measured 30mL serum format for use after toner.

Japanese manufacture: Both strengths are made in Japan as part of KISOCARE's ingredient-focused range.

Benefits

Choose the concentration that fits your routine: Start with NA10's 10% option or select NA20 when you specifically want the 20% concentration.

See the key percentages before buying: Each formula clearly states its niacinamide and PCA-zinc levels.

Keep hydration in the formula: Four hyaluronic-acid forms support moisture care alongside the headline actives.

Add one measured step after toner: The dropper format makes either strength easy to place before moisturizer in an existing routine.

How to Use

Choose NA10 or NA20 according to your experience and skin tolerance.

After cleansing and toner, apply one to two drops of NA10 or three to four drops of NA20.

Spread gently over the face, avoiding direct eye contact, then follow with moisturizer.

Introduce the chosen strength gradually and use sunscreen during daytime routines.

Who Is This For

Product Story

KISOCARE makes the choice unusually clear: NA10 is the approachable 10% niacinamide formula with 2% PCA zinc and 2% panthenol, while NA20 raises the headline concentrations to 20% niacinamide and 4% PCA zinc for experienced users.

Both 30mL Japanese-made serums use a dropper format and include four forms of hyaluronic acid. Instead of treating every customer as if they need the highest percentage, the range lets you select the strength that matches your routine and tolerance.
