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.

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.

Use it before and see if it suits, works for my skin type

Good product and works well Like it’s claim Good product and works well Like it’s claim

Will most likely not repurchase as I don’t notice any difference after finishing the bottle

actually I don't know how this product work, I just want a review point.... thanks

Such a good product, I won’t regret after purchasing on this product.

The product works pretty well with my skin. Not give me a bad reaction at all.

Has really nice texture and absorbs into the skin easily but haven't used long enough to see a huge difference
