Jumiso Niacinamide 20% Serum 40ml

Two types of marks, one targeted solution

When breakouts fade, they often leave behind both red marks (PIE) and brown spots (PIH). JUMISO Niacinamide 20 Serum is a high-potency formula designed to address both types of post-blemish discoloration at once. With 20% niacinamide, it works to visibly even out dull skin tone and areas of hyperpigmentation, while TECA (a highly purified centella-derived complex) helps calm redness in sensitized skin.

High potency, zero irritation—triple-soothing design

A 20% concentration might sound intense, but the triple-calming formula ensures even sensitive skin can use it comfortably.

Stage 1: TECA (asiaticoside, madecassic acid, asiatic acid) immediately soothes heat and stinging
Stage 2: Ivy extract and hyaluronic acid help prevent secondary redness in irritated skin
Stage 3: Allantoin and hydrogenated lecithin stabilize the skin barrier

Clinically tested on sensitive skin and formulated without artificial fragrance or colorants for a gentle experience.

From dark spots to uneven texture, it does more

The violet-tinted watery texture absorbs quickly without any sticky residue, making it ideal for daily use. It helps improve the appearance of dark spots and uneven skin texture, including visible pores. Layer one or two drops before makeup for an added brightening boost. If you're new to niacinamide, start with 2 to 3 times a week and gradually increase to daily use as your skin adjusts.

After toner, before essence and cream

Use your niacinamide serum right after toning, when skin is prepped and receptive. Let it absorb fully before layering on your essence or cream — this helps active ingredients penetrate more effectively. If your skin feels like it needs an extra hydration boost, try adding a drop or two of a hydrating ampoule before the serum.

Morning and evening use

In the morning, it helps even tone and boost radiance. At night, it targets the day's accumulated skin stress. That said, because this is a high-potency 20% formula, if you're new to niacinamide, start with your evening routine first and monitor how your skin responds.

2–3 drops, focused on areas of concern

Dispense 2–3 drops into your palm and warm the serum slightly with your body heat. Apply first to areas where dark spots or hyperpigmentation are most visible, then gently spread across the rest of your face. Press in with your palms to help absorption. You can also use it on body areas like underarms or elbows.

Recommended combinations by skin concern

• Redness and post-breakout marks (PIE): Centella-infused calming toner → this serum → lightweight hydrating cream
• Dark spots and post-inflammatory hyperpigmentation (PIH): Vitamin C serum (morning) / this serum (evening) for time-separated layering
• Pores and excess oil: Lightweight watery toner → this serum → skip or apply cream sparingly on T-zone

Precautions for high-potency formulas

If you're new to niacinamide, start with 2–3 times a week, then gradually increase to every other day, and eventually daily use as your skin builds tolerance. Due to the high concentration, sensitive skin may experience temporary redness — if this happens, try mixing the serum with a hydrating product to dilute it. Store in a cool place away from direct sunlight. If you notice white powder forming around the bottle opening, don't worry — it's a natural occurrence with high-concentration actives. If stinging or irritation persists, discontinue use and consult a dermatologist.
