Olivia from London, UK –
Used it for a month. Noticeable reduction in wrinkles, not too heavy on my face. Worth trying if you’re into retinol products.
Rowan from San Diego, USA (verified owner) –
Saw some small changes after a month. My wrinkles look better. Not greasy and soaks in fast.

ใช้เซรั่มนี้มาสักพัก ผิวดูเรียบขึ้น ริ้วรอยบางลง เนื้อสัมผัสค่อนข้างเบา แต่กลิ่นไม่โดนใจเท่าไร ส่งช้าไปหน่อย ตอนแรกเข้าใจผิดว่ามีวางแค่สีเดียว

I’ve been using this serum for a month. My face looks brighter and smoother, but it’s slightly greasy at first. I prefer applying it overnight. The dropper works well for exact amount control too. Just be cautious if you have sensitive skin like me—start slow.

I’ve been using this serum for two weeks. My skin looks a bit brighter and softer. It didn’t cause any irritation, but I expected it to be bigger in size. Nice bottle though, feels premium when you hold it.
Catalina Ramírez from Madrid, España –
La combinación de bakuchiol y retinol en esta ampolla me ha sorprendido. Mis líneas finas lucen menos visibles después de una semana, dejando mi rostro más luminoso y terso. Definitivamente un producto recomendable para quienes buscan efectividad sin irritación.
Nina Rodríguez from Chicago, USA –
Initially, I was doubtful about adding yet another serum to my skincare routine—especially one boasting ingredients like bakuchiol and retinol. But the allure of combining these potent components in a single bottle captured my attention during a quick stop at a health store in Chicago. After using Cos De BAHA L1 for several weeks, I’m surprised by its effectiveness; fine lines seemed visibly reduced while dark spots faded gracefully into softness! The mild texture offers comfort without overwhelming even slightly reactive complexions like mine. If you value straightforward brilliance for maintaining youthful glow, consider integrating this elixir into your regimen.

I’ve been trying the Cos De BAHA serum for a few weeks. It’s smooth and absorbs quickly, which is nice. I saw some improvement in fine lines after about ten days. It was pricier than my last one, but I’m happy so far. Just keep in mind the scent isn’t very strong.
Aurélie Beaumont from Montreal, Canada –
Après plusieurs semaines d’utilisation, je ressens un véritable changement dans ma peau. Une luminosité qui éveille mes matins! En plus, la douceur de l’application est inoubliable.
Sofía Arreola from Puebla, México –
Descubrí Cos De BAHA y mi piel ha cambiado radicalmente. Aplana las arrugas con un brillo natural que me hace sentir más joven.
Amélie Laurent from Montreal, Canada (verified owner) –
As someone who has long battled fine lines and uneven skin tone, discovering Cos De BAHA’s ampoule was like striking gold. Just a few drops in the morning transformed my routine into a little ritual of joy. The soothing properties really worked wonders on my delicate complexion here in Montreal’s chilly winters!
