SKIN1004 Niacinamide 10 Boosting Shot Ampoule: Skin Types?
SKIN1004's Niacinamide 10 Boosting Shot Ampoule (10% niacinamide, USD 19.80 on 2026-09-26) is documented for oily, combination, dull and uneven-texture skin, with a graduated routine built to extend it to sensitive skin.
Published · Updated
SKIN1004 Niacinamide 10 Boosting Shot Ampoule, a 30ml treatment from the brand's LAB IN NATURE line, sells for USD 19.80 on its own store as of 2026-09-26, down from a USD 22 list price. The deciding axis for this question is which skin types the brand itself documents the ampoule for, since no independent clinical test of pore size or sebum reduction exists for this category, and SKIN1004's own product listing settles that axis with four named skin types plus a graduated application schedule built to extend the ampoule toward sensitive skin as well.
SKIN1004 Niacinamide 10 Boosting Shot Ampoule 30ml
Within SKIN1004's LAB IN NATURE line, Niacinamide 10 Boosting Shot Ampoule 30ml is formulated at a declared 10% niacinamide concentration, the figure the brand prints directly on the product's own page.
The official listing for centella niacinamide serum is on the SKIN1004 store.
Among the ampoule's 21 listed ingredients, three do the documented work the question asks about: Niacinamide at 10%, Tranexamic Acid for texture support, and Hydrolyzed Sponge, a spicule ingredient the brand describes as microneedle-like structures that open micro-pathways for ingredient delivery. SKIN1004 attributes a 132.8% increase in absorption to those spicules compared with a spicule-free control formula.
SKIN1004's own listing assigns this ampoule to Oily, Combination, Dull and Uneven Texture skin, and the product's Shopify tag set adds Sensitive to that group. Niacinamide 10 Boosting Shot Ampoule is suited to oily, combination, dull and uneven-texture skin on the strength of that listing, and its graduated starting schedule extends the same ampoule to sensitive skin as well.
The brand's own directions place the ampoule after cleansing and toner, with an adaptation period ahead of full use:
- Apply after cleansing and toner.
- For the first one to two weeks, use two to three times a week, about 0.1ml per concerned area.
- After adaptation, frequency can rise toward daily or every-other-evening use.
- Follow with a moisturizer.
- Avoid the eye area, and rinse with water on contact.
SKIN1004 lists four product benefits for this ampoule on its own page:
- Pore refining
- Brightening
- Radiance boost
- Skin smoothing
Read together, the tag set, the 10% concentration and the graduated two-to-three-times-weekly start make the documented fit for this ampoule oily, combination, dull, uneven-texture and sensitive-prone skin, the full span the question asks about.
