With some Vitamin C serums/ampoules, my face gets irritated. However, this ampoule didn't irritate my skin at all. The texture is watery, which I like. Since I've only used it a few times, it's difficult to assess the effectiveness of this ampoule by itself. Eventually, I'm hoping it will help fade my acne marks and hyperpigmentation.

I really really really love these product so so much!!! Absolutely amazing! Obsessed!

My mom loves it and she’s at her 5th bottle already

Amazing product I love it

Been using 5 bottles of this. It’s gentle and brightens my face.

I wasn’t able to use this one before the expiration date so I’m in the middle for this one

This is definitely one of the best vitamin c serum in KBeauty.

I can see the improvement in my skin after a few weeks

use this to glow and brighten in the morning. gives a nice glow but no dramatic changes

Asorb well, no stickiness, no irritation

I love this product because it helps my skin with the pores and controls oily skin. I love its ingredients:

My favourite serum to use in the morning!! I love love love how lightweight this feels on the skin and it absorbs pretty fast too. I love it!

Probably my new Vit C + Niacinamide serum. I use this in the morning and it's absorbs well into my skin. Love it and will repurchase for sure! It's not sticky on the face unlike other Vit C and Niacinamide serums i used.

Es un serum con Niacinamida que ayuda a igualar el tono y ayuda con la hiperpigmentación adicionado con varios extractos para las manchas

70% of Hippophae Rhamnoides Fruit extract is contained, which is a component extracted from a tree called 'Sea buckthorn'. Sea buckthorn contains a large amount of vitamins A,B,C,E,K and various amino acids to brighten uneven skin tone.

Love it, love it and love it, will buy again!

This ampoule gives you clear, radiant skin. The rich vitamin component of vitamin tree fruit extract penetrates deep into the skin to brighten the skin. It contains 70% of vitamin tree fruit extract that turns mottled skin into bright skin, and cream that further strengthens moisture with hyaluronic acid and natural moisturizing factors. It is light and quickly absorbed into the skin. . You can definitely feel the difference in skin tone before and after application.

I have no idea how it's work. I got order from customer.

I have’t try this one yet but i saw a review video that said it was good so i’m really interested. Hope it works as expected

Great serum. Hopefully this works!

This is my first purchase of this ampoule, and it will not be the last. I started with Isntree when I became interested in Korean skincare, and I am still loyal to this product. I love its mildness because I have sensitive skin.

Great beginner-friendly vitamin c serum.

initial thoughts: light watery serum, barely noticeable citrus smell, slight tackiness on skin, good size bottle for $10 (on sale), label comes off easily prob for recycling purposes but I had to trim it. bought bc I finished my versed vit c oil and wanted a k beauty replacement, will update with results

between ampoule or cream i prefer the cream but i assume it's better to use both in combination.

Good product that works like their claim, would repurchase!

I love love love love.

I love love love

I love love love.

Repurchased many times since now my skin barrier is improving and stronger. I love it even more. I don't have issue with dark spots and marks but definitely see result in skin complexion, skin is a bit clearer and more vitalised.
