RAMOSU – Bifida Ferment Lysate 100 Review

hihi everyone, today’s post will be a full review on the Ramosu 100 Bifida ampoules I got from Stylevana. If you want to see the other items I picked up, read that post here

I wanted to experiment with k beauty dupes for the Estee Lauder ANR serum. I absolutely LOVE the ANR serum, its pricey but its so worth it! I usually bulk buy it when they do their buy 1 get 1 free promotion but the problem is they haven’t done this in 2 years and my stash is down to the last 1, sigh. I worked it out that they run this promotion when they update the ingredient list so that they can quickly get rid of the old stock. the last update I feel was 2022 when they did the promotion.

Anyways the promotion hasn’t be run in the last 2 years so I decided to find some k beauty dupes I can use whilst waiting for the promotion to come back or a really good offer on. Estee Lauder do have some great offers from time to time so really its only a matter of time LOOL.

Criteria for Estee Lauder ANR dupes

This is the current full ingredient list for the ANR, what I am looking for in a dupe is something as close to this OR has the key ingredients I have put in bold, but the main ingredient I look for in dupes is the Bifida Ferment Lysate since its the 2nd ingredient in ANR therefore in high conc

Ingredients: WaterAquaEau, Bifida Ferment Lysate, Peg-8, Propanediol, Bis-Peg-18 Methyl Ether Dimethyl Silane, Methyl Gluceth-20, Glycereth-26, Peg-75, Butylene Glycol, Adansonia Digitata Seed Extract, Tripeptide-32, Sodium Hyaluronate, Yeast ExtractFaexExtrait De Levure, Lactobacillus Ferment, Cola Acuminata (Kola) Seed Extract, Anthemis Nobilis (Chamomile) Flower Extract, Hydrolyzed Algin, Pantethine, Caffeine, Lecithin, Sodium Rna, Bisabolol, Squalane, Glycerin, Oleth-3 Phosphate, Caprylyl Glycol, Oleth-3, Oleth-5, Choleth-24, Hydrogenated Lecithin, Jojoba Wax Peg-120 Esters, Ceteth-24, Tocopheryl Acetate, Carbomer, Triethanolamine, Tetrasodium Edta, Bht, Xanthan Gum, Potassium Sorbate, Disodium Edta, Phenoxyethanol, Red 4 (Ci 14700), Yellow 5 (Ci 19140) 

It is well known that k beauty have a lot of products with Bifida Ferment Lysate in them so I turned to the k beauty world for dupes. I picked up 3 for my 1st round of testing and I started with the RAMOSU – Bifida Ferment Lysate 100.

RAMOSU – Bifida Ferment Lysate 100 – this is a 100% pure bifida ferment ampoule with nothing else added to it. I had never heard of the brand Ramosu until browsing on Stylevana and I got it because it was on clearance. You get 5x10ml bottles, I have finished 3 so far out of 5. This ampoule promises a special skin feeling in 28 days


This was an easy addition to my skincare routine, it layers well with other products and pairs well with other actives. I have used it with high strength retinol, acids, peptides with no irritation. I started using this on the 20th of March after I had just finished a bottle of ANR. I finished a 3rd bottle of the Ramosu on the 2nd of May before taking a 1 week break to use ANR then back to Ramosu.

Is it similar to ANR? In terms of ingredients, this product only has the bifida ferment so its lacking the benefits of other ingredients in a well rounded serum. To combat this I just layered other products with some of the ingredients in ANR e.g peptides, glycerin etc. The serum itself is not hydrating.

Results: I think that the ampoule has helped maintain a healthy glowing complexion like ANR but I can see a difference. ANR makes my skin feel smooth, soft and radiant and the results are literally overnight. I just didn’t get that from this. In the pictures and ignore my spot treatments, I feel like there is a slight difference in terms radiance and feeling of my skin. My skin looks great but I can feel the difference


Is it a dupe for ANR? Well it has the main ingredient which is the bifida however the lack of other ingredients means you are not getting full benefits so I would say its not a dupe.

Is it a great product? absolutely, if you are the type to layer on skincare then the lack of other ingredients wont bother you so much because you will be getting them elsewhere. The only time this was annoying was when I wanted a lazy pm routine, the lack of hydration from ramosu meant I couldn’t just use this plus a cream because it wont be enough

Do I recommend it: yes and no- yes because for the price you pay for 100% bifida its amazing, its well packaged and it actually leaves the skin great but no because there are no many other dupes that are well rounded in ingredients and may work better.

Bottomline: it doesnt hurt to try this, its £10 for 50ml but it is not a dupe for ANR. Get it to try as a product because you want to experiment with bifida but not as a dupe for ANR

I have 20ml left of this to use up then its onto the next dupe!

I hope this review is helpful! Catch you later
