ISNTREE Hyper Niacinamide 20 Serum 20ml | 10x Hyaluronic Acid | Helps Minimize Pores | Evens Skin Tone | Korean Skincare

I absolutely love this lotion! The texture is smooth and creamy without being greasy, and it absorbs quickly into the skin. I’ve noticed a real improvement in how my skin looks and feels since I started using it. Definitely a new favorite — highly recommend!

I absolutely love this. I was already using mendalic acid and kojic acid for my hyperpigmentation and wasn’t seeing too much of a difference. It wasn’t until I used this 20% niacinamide, that I actually started to see a HUGE improvement almost immediately in both the texture of my skin and the lightening of dark spots! I have been getting compliments on my skin and it continues to improve daily. The serum is clear, odorless, lightweight, and easy to absorb. I put it on after I apply toner and then layer my other products over it. My only gripe is that the bottle is small and black (to protect it from sunlight, I’m assuming), so it’s hard to see when you’re running low, but it works so well, I have already purchased another bottle.

Solo si tienes la piel muy sensible no lo uses pero si tienes piel mixta a grasa sin brotes te ira de maravilla con este producto,alta luminosidad después de usarlo

Really good for oily skin

So far so good it does control the oiliness of my skin. I do have to apply it more than once a day.

Niacinamide is supposed to brighten the skin and since I’m familiar with the brand along with the super high percentage of niacinamide, I really have high hopes for this one. I really like the texture of the formula. The gel to liquid soaks in immediately and plays well with my other skin care. It could be the combo of actives I’m using but I’m pretty sure that this is what has really accelerated sloughing off of dead skin cells. I just have to remember to buff well in the morning so all the flakey skin is gone. My skin is looking brighter already but I’m hoping some summer sunspots will start fading soon. Will report back.

This is a good Niacinamide and Hyaluronic Acid serum in a tiny bottle. Fortunately it only needs a few drops to work it's magic so it has lasted longer than I expected. I mix in an EGF (Epidermal Growth Factor) concentrate to make a perfect serum that I used when taking a break from Tretinoin. This and retinol have a similar but gentler effect. I'm now using this plus the EGF as a post micro needling session serum and it's great for that!

Been using this product for about a month. Using for brightening a shrinking my pores. It seems to be maintaining the effects of my previous medication hydroquinone which I'm off now. Not seeing much difference in my pores. Will give it a few more weeks.

Die Verpackung ist schön, die Konsistenz und das Tragegefühl sind angenehm, keinen besonderen Geruch vernommen und auch keine nennenswerte Wirkung festgestellt.

I didn't check the size prior to purchasing so I was surprised it was only 20 mls! You can buy the same strength in bigger bottles for far cheaper and they do the exact same thing so I will not repurchase.

قوام سائل لسا بصراحة ما حسيت باي فرق اشتريته عشان المسام

original. The first expensive serum on amazon with safe-label "nobody opened it". And perfect high quality pack for serum. But Serum is very liquid, almost not silky silicone. For me its fine because I took it for some dots on my back. But Im not sure how it will be on face. I use other brends with 10%
