SKIN1004 Niacinamide 10% Boosting Ampoule, Brightening Serum 30ml

Still working on interchanging the days and consistency of application. No skin irritation at all.

I've been using it after washing my face and do notice and improvement to my skin

Excellent Niacinamide ampoule, did exactly what it said it would do and left my skin looking & feeling very smooth and glowy; my pores were significantly smaller after just one use!

It’s works, my face look different more young

Love the item

Love this niacinamide. It’s not thick so it’s not sticky. Way way better than that popular 10%niacinamide

Love this!

Love the product , not a fan of the stout bottle .

All good

this is the serum that i have been looking for all my life. I’ve dealt with stubborn dark spots that have been on my face for months, possibly even a year and this drastically reduced their appearance in as little as 3 weeks.

Highly recommend this it’s very moisturizing and brightening. It’s easy to apply and lightweight. I definitely will be re-ordering.

I like it!

Love all the skin 1004 centella products. Using this daily or more. Definitely feel improved texture of my skin. Softer and more supple.

I like the niacinamide bottle

Love this!!

Haven’t seen results yet but skin feels better

The serum is very gentle and leaves my skin radiant. I love its texture because it absorbs quickly into the skin. If you're interested, you can try it; I recommend it because it worked for both me and my daughter. Made in Korea.

This boosting shot works well. When you apply it, you can feel tiny needle-like sensations on your skin, but it lasts less than a minute, and if I understand correctly, that is how it is supposed to feel. I have been using it for a week, and my pores already look smaller.I also like how my skin feels after using it. It does not dry out or tighten the skin, which is very important for me.

I have a sensitive skin so I used 1 drop each on my cheeks. It really make your pores smaller and smoother with the help of moisturizer after applying. Overall I like the product.

Skin1004 does it again! I've been using this serum for approximately 4 months now, every other day, since this is a 300 spicule. So far, I haven't had any negative reactions to it. I found that I had the best result when I used it with their claiming toner pads and layering with the Skin1004 Hyalu-Cica Blue Serum (both are some of my fave products with multiple repurchases tbh) and then finishing with a barrier cream. It's definitely a serum that is easy to layer as it sinks into your skin so well. Sometimes I layer it with heavier/thicker serums, and it still never irritates my skin.Overall, I definitely saw improvements in my complexion and my hyperpigmentation fading. It definitely brightened my skin, and I saw a noticeable difference in my skin texture and pores (though I don't generally have large pores to begin with). You can see the evidence of the TXA ingredient if you accidentally splash the serum on the bottle and leave it out to dry (see the white spots on my bottle in the picture 🤭). I would highly recommend this if you are looking for hydration and skin brightening.

This Korean serum is an absolute glow-booster. The 10% niacinamide with tranexamic acid noticeably brightens skin tone and smooths texture. It’s hydrating yet light enough to layer under makeup, with zero irritation.✅ Brightens and refines skin tone✅ Gentle enough for daily use✅ Hydrating and lightweight✅ Helps even out pigmentationPerfect for anyone wanting that clean, radiant “glass skin” look.

This feels light on the skin and sinks in quickly. It gives a steady brightening effect and helps keep the skin hydrated. The texture is smooth and does not leave any sticky finish. A good option if you want a simple serum that supports clearer and more even skin.

ممتاز ممتاز

I appreciate that the texture is initially thick but quickly absorbed after application. My skin tone appears more even, and dullness has faded a bit. My skin also seems smoother, fine roughness and uneven texture have softened.The product is upfront on the concentration (10%) and I didn’t get strong irritation, stinging, or redness with gradual use, though I do follow with moisturiser and sunscreen. This is in comparison to competitors that simply states "99% pure niacinamide" which doesn't mean much.This ampoule is a solid choice for those who want gentle but visible improvements over time.Disclaimer: I received this product for free through the Vine program.

This serum is very nice and good on my skin. It is able to help repair and clear up blemishes on my face from pimples. My skin is brighter and smoother too. Serum doesn't have any scent, it is thick, so a little goes a long way and its hydrating and doesn't irritate my skin. Definitely recommend adding to your skin care routine.

Been using this serum a bit now and it feel pretty good on my face. Texture is a bit thick but still smooth, and my skin take it in fast. No bad reaction, no strong smell, just easy to use at night. My skin look a bit calmer and less red after some days. Packaging look nice too. For the price I feel happy and it seem doing something.

No scentReally lightGoes on nicely and absorbs easyMakes my skin feel super niceCan use other moisturisers afterwards

I’d heard great things about SKIN1004 and was excited to try the Niacinamide Boosting Shot. The texture is watery and light, but still feels hydrating on my dry-combo skin. After two weeks, I haven’t seen major changes yet, but I’m happy it hasn’t caused any breakouts.The packaging is sleek, modern, and looks high-end on my vanity. Overall, it’s a gentle and hydrating product that layers well with the rest of my skincare.
