The texture is a bit watery, so it can run if you apply too much at once. Also, if your skin is very sensitive, starting with 10% niacinamide might cause slight tingling during the first few uses. 

I’ve been using the Skin1004 Niacinamide 10% + Zinc serum for two weeks, and I’m loving the results! It feels lightweight, non-sticky, and layers well under other products. My skin tone looks more even, pores appear smaller, and breakouts have calmed down. I also love that it’s gentle — no irritation or dryness. Great formula with Centella for added soothing. Highly recommend for oily or combination skin!

The bottle design is minimal and pretty, but I wish it had a smaller opening — it can pour out a bit too much product at once.

I love how lightweight yet deeply hydrating this toner is. It absorbs quickly, leaving my skin soft, smooth, and refreshed without any stickiness. The subtle rice scent feels so calming and luxurious. My skin looks brighter and feels more balanced after each use — a perfect prep step before moisturizer or mask

It can feel slightly slippery to handle when applying, but it’s not a big deal considering the results.

This mask feels cooling and soothing from the moment you apply it. The gel texture hugs the skin perfectly and leaves a radiant, “glass-skin” glow afterward. It’s great before makeup or whenever my skin feels dull. My complexion looks calm, even, and hydrated.

	•	The effect doesn’t last long.
	•	Not worth repurchasing for the price.

Overall, while it gives an instant boost of freshness, the results fade quickly. I wouldn’t buy it again.

	•	Leaves the skin looking fresh and radiant.
	•	Feels lightweight and comfortable on the skin.
	•	Easy to apply and rinse off.

	•	May be too mild for those needing deeper exfoliation.
	•	Brightening effect is subtle and requires consistent long-term use.
	•	Can ball up too much if you apply too much product at once.


	•	Extremely gentle exfoliation — perfect for sensitive skin.
	•	Leaves the skin smooth, soft, and brighter after each use.
