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!

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!

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!
