Ho provato il Siero Barriera Biome di Earfit e ne sono rimasta colpita. La texture leggera penetra rapidamente, lasciando la pelle nutrita senza pesantezza. Nota evidente di miglioramento dell’elasticità: per una lucentezza naturale che attira attenzione.
Ingrid from Oslo, Norway –
As a resident of Oslo, I can’t praise the Earfit Biome Sera Barrier Serum enough! In Norway’s shifting weather—those icy winds can be so cruel—I’ve struggled with keeping my skin adequately hydrated. The lightweight feel is surprisingly effective; it penetrates layers swiftly without leaving any greasy residue, which matters a lot when you’re constantly on-the-go in busy cafés or bundled up in woolens. I’ve noticed reduced tightness and an improvement in dull spots after using it daily for just two weeks—a rare victory indeed against this harsh climate! This serum blends traditional wisdom and modern science beautifully to create radiant results that truly reflect Norwegian resilience.
Naturally derived mugwort offers comfort to sensitive areas, easing discomfort from abrupt temperature changes.

Tatiana from Madrid, España (verified owner) –
Siempre he sido escéptico con respecto a los sueros para la piel; muchos de ellos prometen milagros sin cumplirlos. Sin embargo, después de usar el serum Biome Sera Barrier durante un mes en Madrid, mi percepción cambió drásticamente. La textura ligera me hizo sentir como si estuviera tratando algo natural y no pesado sobre mi rostro. Comenzó a revitalizarme desde dentro: adiós sequedad constante y esas zonas rugosas que parecen empeorar por temporadas. Un día noté una luminosidad que creía imposible volver a tener después del invierno prolongado aquí – es decir, ¡qué sorpresa! No sólo ayuda con las arrugas finas sino también ilumina tonificando ese matiz pálido cotidiano mediante sus extractos naturales integrados que protegen efectivamente mientras reparan dańos anteriores.

Ich kann kaum fassen, wie sehr dieser Serum mein Gesicht verwandelt hat. Nach nur ein paar Anwendungen ist meine Haut praller und strahlt vor Frische! Ich liebe das Gefühl von Hydration und die Beruhigung dank dem Beifuß-Extrakt – er macht wirklich einen Unterschied.
Jin Lee from Toronto, Canada (verified owner) –
Okay, let’s chat about this serum. I got the earfit Biome Sera Barrier Serum after my friend in Seoul wouldn’t stop raving about how hydrated her skin looks now – and wow, she wasn’t wrong! Like, it feels almost like a glass of water for your face. I usually struggle with dry patches since winter is brutal here in Canada 🇨🇦, but man, my skin soaked it up instantly without feeling greasy at all! Plus there’s a chill factor because it has mugwort — definitely mellowed out some redness I’ve been dealing with. So if you’re tired of battling tightness every morning (ugh), you should give this stuff a go!
Emily from Toronto, Canada –
Honestly, I was a bit skeptical at first, but this serum has really impressed me! I’ve been using it for about 3 weeks now, and my skin feels so much more hydrated. I tend to have dry skin, especially during the winter months, and this has made a noticeable difference. It absorbs quickly without any oily residue, which is a huge plus for me. Tbh, I wish it came in a larger bottle because I could see myself using this daily for quite some time. Overall, I’m really happy with my purchase!
Jessica from Seattle, USA –
I started using the earfit Biome Sera Barrier Serum about three weeks ago, and honestly, my skin has never felt better! I used to struggle with dryness, especially in the winter months, but this serum has been a game-changer. It’s so lightweight that it absorbs quickly without leaving any greasy residue. After applying it, my skin feels plump and hydrated all day long! 😊 The only downside is that I wish it came in a bigger bottle since I’ve been using it so frequently. Overall, I’m super happy with the results and will definitely be repurchasing!
Sophie from New York, USA –
I’ve been using the earfit Biome Sera Barrier Serum for about 3 weeks now, and I gotta say, my skin has never felt better! I was dealing with dryness from the winter air, but this serum has given me such a boost of hydration. The texture is super lightweight and absorbs quickly, which is perfect for my busy mornings. Honestly, I noticed a difference in elasticity after just a few uses! My only wish is that it came in a larger size because I’m already halfway through the bottle. Happy with my purchase and will definitely repurchase!
