Skin Type

Oily and combination skin dealing with visible pores fits the SKIN1004 Niacinamide 10 Boosting Shot Ampoule, since the maker reports visible improvement in pore size, depth, and count after four weeks of use. Dull, uneven toned skin suits this ampoule because 10% niacinamide, Tranexamic Acid, and Ascorbyl Glucoside are formulated for triple tone correction (brightness, even tone, reduced yellow tone) within two weeks per the brand's clinical summary. Skin that reacts easily to actives can still introduce this ampoule gradually, since SKIN1004 lists a completed skin irritation test for the formula and recommends a two to three times weekly adaptation phase before daily use.
