Didn't expect much but better than expected! easy on sensitive skin!

It's not bad but it's not wow either. But the price is really affordable.

They say the ingredient in this is the same as what is in Estee Lauder advanced night serum. I love this and I do think my skin looks much better in the morning after using this at night.

I've just started using this product so it's hard to say if I am yet seeing the results of this serum, but I have been using a bifida serum before starting this one. I will say the peptides in the formula make for a cosmetically elegant formula that is comparable to the manyo bifida biome ampoule serum, which I was using before, but this one is more suited towards a dryer skin type in my experience. I have used this as my only serum (aside from actives) every night for a week and my skin is glowing and even toned, and I do believe that the post-biotic ingredients in this help promote that healthy skin that I love.

I like this better than the Mixsoon equivalent.

Nice texture that absorbs easily. no dramatic changes

love how it smooths my skin bumps and improved glow! thanks Isntree!

this is my first time trying isntree and it definitely was worth it to buy this ampoule. it feels so hydrating and makes my skin look very dewy

Light, no sticky, and smooth skin without any irritation. Love the product

it is very nourishing, doesn't irritate my sensitive skin, full of peptide and good for aging skin.

Great probiotic skincare product, easy to switch in and out of routine, works well with other products.

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

I was scared to try an ampoule with bifida extract because of my sensitive skin but I'm happy to say that I didn't experience any irritation . It leaves my skin nourished , soft and plump looking. I'm on to my second bottle already.

Between this and the numbuzin no3 serum I get all the bifida benefits

i only have high praises for this. used it down to the last drop and can't wait to use the next bottle -- thankfully it's just the packaging that has been changed but it is the same awesome product.

I absolutely love this serum (yes I know it says Ampoule but It feels an act like a serum and it's basically the same thing) But the ingredients list on this product is absolutely amazing from the fermented ingredients to the peptides to the other hydrating soothing and brightening ingredients this is a multitasking product that I absolutely love! It's brightening it's hydrating And I feel like it's firmed up my skin a little bit since I started using it. I bought two bottles right off the bat when I first ordered it and I'm so glad that I did. This is going to be a staple in my skin care routine!

I liked it. This product is very good. would recommend.

Good product, love it works very well.

My friend recommended this for me and now I love this product with affordable price and high quality. I would like to recommend this to everyone out there. When on next sale I will definitely purchase again really worth the price. Especially anyone who have sensitive skin like me can be use too. Don’t miss the good one !!

Amazing product. Love the texture and my skin adores it. Definitely repurchasing.

Great product with nice ingredients

Really good for dry skin. Make your skin plump.

Amazing serum, the only constant in my routine in the last 2 years. Great list of ingredients, fragrance free, no essential oils or alcohols, very hydrating. It gives a nice glow to my skin, I really love it!

This is a lightweight hydrating serum that truly brightened my oily skin. I loved using it and repurchased many times

I really enjoyed this in my routine. It has a watery texture but it brought some brightening benefit to my skin.

I haven’t tried yet. Will update later.

The best of the best! I really like it and will recommend to my friend ♥️

Great size for a serum and good ingredients. Feels nice and isn't sticky.

such a great deal, love the texture, non sticky or tacky. So lightweight and absorbed well.
