Skin1004 Madagascar Centella Niacinamide 10 Boosting Shot Ampoule

10% is a high but well-established cosmetic strength. It helps even out tone, fade the look of dark spots, balance oiliness and refine the look of pores. Most skin tolerates it well, but some people notice temporary warmth, redness or tingling at first. Starting every other day and building up gradually, as the box advises, helps your skin adjust.

The formula contains hydrolyzed sponge, natural micro-spicules that the box calls "Centella Spicule 300 Shot". They create a light prickling sensation as you spread the ampoule, which is normal and fades within a few minutes. Strong burning, lasting redness or swelling is not normal, so rinse it off and stop using it if that happens.

After cleansing, use a toner or toner pad, then spread a few drops over your face, avoiding the eye area. Once absorbed, follow with a moisturiser. The box notes it's high in active ingredients, so patch-test first, start every other evening and increase gradually to daily use. Close the cap tightly after each use.

Besides 10% niacinamide, it contains ascorbyl glucoside, a stable, gentle vitamin C derivative high in the formula, and tranexamic acid, known for targeting the look of stubborn dark spots. Polyglutamic acid and panthenol keep skin hydrated and comfortable. Centella and madecassoside appear only in small amounts, as supporting ingredients.

Both target dark spots and uneven tone with niacinamide and tranexamic acid. Skin1004 Niacinamide 10 is stronger, with 10% niacinamide, a vitamin C derivative and micro-spicules, so it suits oily, resilient skin with visible pores. Numbuzin No.5+ is gentler, with 5% niacinamide and 5% panthenol, and suits sensitive or breakout-prone skin better.

Yes, with care. You can layer it after a pure vitamin C serum such as Cos De BAHA VA in the morning. With retinol, alternate nights rather than using both together, as micro-spicules plus retinoids can be too much for many skin types. Avoid using it on the same night as strong exfoliants, scrubs or clay masks.

It's fragrance-free and has completed a skin irritation test, but the combination of 10% niacinamide and micro-spicules makes it a strong product. If your skin is very sensitive or easily flushed, start with a gentler option such as Numbuzin No.5+ Serum, and use the fragrance-free Skin1004 Centella Ampoule to keep skin calm.

Yes. It's well suited to men with oily skin, visible pores and dark marks left after breakouts or razor bumps. Because of the micro-spicule tingle, use it in the evening or several hours after shaving, not on freshly shaved skin. Follow with a light moisturiser, and wear sunscreen every morning.
