What they liked

Light texture, absorbs quickly
More moisturizing than expected

What they flagged

Mild sting, risky for sensitive skin
Spicule-based, not a standard serum

What the gurus are saying

This ampoule stings mildly at first but absorbs quickly into a comfortable, moisturizing texture that surprised reviewers with how hydrating it feels. One concern: it's a spicule-based product (tiny exfoliating particles), which means those with sensitive skin may find it irritating, though it appears gentler than other spicule serums on the market and might be worth patch testing first if you've struggled with similar formulas before.

"It has a mild sting that doesn't last long, so if you have sensitive skin be careful, but it's great, the lightest texture of the three, it absorbs fast and it's very comfortable, more moisturizing than I expected."

"This is Skin1004's Niacinamide 10% Boosting Shot Ampoule. I was so flustered when I got this, I guess I missed the word shot on there, which refers to these spicule based products, I really did not know that's what I was buying in a 10% niacinamide serum, and I do not think I would have bought this if I had realized. They're claiming this is a 300 level of intensity, but I don't feel it, and I definitely felt the 100 level from a different spicule product I've tried. So I'm perplexed by this one. This might possibly be the first time I may be able to stick with a spicule product, the others have just been too uncomfortable for me, my sensitive skin has just been showing with how I felt with other spicule products. But I'm going to give this a try."
