A True First-Step Essential That Makes Everything Work Better
I’m 52 and post-menopause with mature, sometimes sensitive skin, and this IOPE Bio-Conditioning First Step Essence has become a non-negotiable part of my routine. If you’re familiar with Korean skincare, you know how important a true first-step essence is — and this one absolutely delivers. I use this immediately after cleansing (usually with the IOPE Bio-Conditioning Cleansing Foam, which I also love), and it instantly makes my skin feel balanced, hydrated, and ready for treatment products. The texture is lightweight and watery, but it doesn’t just disappear — my skin actually feels softer and more receptive right away. What I appreciate most is how calming and smoothing this feels. There’s no fragrance irritation, no tackiness, and no residue. It absorbs quickly and layers beautifully under serums and creams. Since adding this consistently, I’ve noticed my skin looks more even and hydrated overall, and my other products seem to perform better. I also use several products from the IOPE STEM III line, and this essence pairs perfectly with them. It feels like a true supporting step that enhances the entire routine rather than just being an extra layer. My skin looks fresher, more resilient, and has a healthier glow — especially important for mature skin that can easily look dull or dehydrated. This is definitely a step up from basic toners and feels more treatment-focused and refined. Like most IOPE products, it’s thoughtfully formulated, gentle, and very effective. If you already enjoy IOPE skincare or are building a more intentional routine, this is an excellent foundation step. Highly recommend — and I will absolutely continue repurchasing.

Go-to essence!
This is a re-purchase for me! Currently on my second bottle. I use this after my toner, and can feel it gently tightening my skin and preparing it for better absorption of my serums. Love how gentle it is, and how well it seals in moisture.

Iope essence
I love Mathis oops essence. It works really well at brightening my skin tone. It’s very moisturizing and it is priced well. Happy with my purchase

Love that IOPE bio-conditioning essence
I love this essence. It’s my second purchase though 1st time purchased on Amazon. I find this essence so cooling and refreshing. It’s pricey, but recently I was persuaded by reviews to try layering three essences from Mixsoon, each less costly than Iope, but they add up! I enjoyed the hydrating effect, but I don’t think the sensitivity issues addressed by the Mixsoon approach are the same as mine. I think once I finish up my remaining Mixsoon, I’ll just stick with my beloved Iope, perhaps wiyh a little COSRX power essence on certain days, a unique essence that I think may help sesl in sone of that IOPE hydration. I'm even considering trying IOPE’s new essence-based cleanser and moisturizer. Each are pricey, but so is trying many products that don’t work for me. I believe in Iope. One part of Iope’s lines I have yet to experiment with are their products containing retinol. That’s the kind of sensitive skin I do have, but one day I will try.

Good option for pitera lovers on a budget
Obviously it’s a different strain because there gosh hundreds of thousands of galactomyces strains out there now but the Bio-redux alpha in this is chefs kiss. I am a multiple times over repeat buyer. I’ll keep buying it too. Yes, I’ve bought the pitera products too. I like the results. I like the formulation. If you ever encounter the sheet mask that has this in it? Buy it.

Great Deal but isn’t the Full Size
Bought this while it was on sale for Black Friday. Love this skin conditioning essence from Iope — has worked for me for years on my very sensitive skin in tandem with their other product lines (I use the Stem III line currently). My only gripe was that I wasn’t paying attention when I purchased and didn’t realize this was only “half” the size of their normal full sized essence bottle. I wanted to return and exchange to purchase the larger OG bottle, but saw that it wasn’t available for purchase on the Iope Amazon storefront, so I ended up keeping it. Wish Iope would offer the full sized bottle via Amazon!

Must have Essence!
IOPE Bio-Conditioning First Step Essence is an absolutely amazing product. I purchased the IOPE Stem III gift set with the toner and lotion, as well as, the Stem III Skin Calming cream. They worked perfectly together. By using the Bio-Conditioning First Step Essence before applying other treatments it helped the other products to absorb easily. It left the skin hydrated and smooth. It has a watery texture and did not have a fragrance.

洗顔直後に使う導入化粧水としてこれで三本目になります。今の季節(夏場)とそれ以外の季節でスキンケアを変えないといけないくらい酷い混合肌ですが、これだけは1年を通して使うことができています。塗って次の日の朝驚くような変化を求める向きではなく、地道に使い続けることが大切だと思っています。

コスメ好きでアモーレの製品も今まで沢山使ってきたけど、、、これはびっくりするくらい付けてる気がしない。 水の様に繊細な使用感。。。

別サイトの公式で1度購入し、良かったのでAmazonでリピしました。 グリセリンが入ってるとすぐニキビができるのでグリセリン入は避けてましたが、今回Amazonで購入したら日本語で成分が書かれていてグリセリンが入ってましたw が、この化粧水を使った事で出来るニキビは無かったのでこの化粧水は大丈夫でした。 (表記されてた順番的に高配合ではなさそう) また、グリセリンが高配合で肌に付けるとベタベタもっちもち系の乾燥肌さん向けの化粧水を使用するとすぐに毛穴が黒ずむのですが、この化粧水はそんな事なかったです。 小さいサイズを朝晩ほぼ毎日使用(1回で500円玉1.5個分くらい)して1ヶ月半くらいで使い切りました。 保湿系の化粧水や美容液を使用するとすぐに肌荒れを起こすので今までゼオを使ってましたが、冬は乾燥が気になりこちらを使用し始めましたが、肌荒れを起こすことも無くその後のメイクにも影響しないし、ほどよく保湿してくれるのでお気に入りになりました! 使用感的にはさっぱり寄りになるのかな? おそらく普通肌、シミとニキビができやすい30歳女のレビューです。
