7 reviews for ISOI ACNI Dr. 1st Control Serum, 40ml

  1. ليلى Cairo, Egypt

    اشتريت هذا السيروم لحب الشباب ونجح فعلاً. عند الاستخدام كان قوامه خفيف وسهل الانتشار. لاحظت تأثير جيد في تخفيف الالتهاب ولكنه جاء بلون مختلف قليلاً عن الصور.

  2. Rowan Denver, USA

    I used this serum for redness and breakouts. It worked great to calm my skin fast. The texture is light, absorbs quickly without stickiness, which I really liked. Definitely feel less oily throughout the day now.

  3. Harper London, United Kingdom

    This serum really helped calm my irritated spots. It feels lightweight and absorbs quickly. I noticed less oiliness after just a few days of using it. Worth trying out for anyone with breakout issues.

  4. Amir from Dubai, UAE

    قد تبدو مكونات سيروم ISOI ACNI Dr. وكأنها مجرد وعاء من الوصفات، إلا أن هذا المنتج يستحق التجربة بالفعل! عانيت لفترة طويلة من البشرة المتهيجة والمحتقنة، وكانت معالجة الزيوت بشكل يومي كابوسًا يلازمني حتى اخترت هذا السيروم لدرجة كبيرة تم الاستهزاء بها أول الأمر لكن بمجرّد استخدامه شعرت بإشراقة استثنائية كما لو كنت أقف تحت شمس ليون دافئة بعد منتصف فصل الربيع. تركيبته النابعة من الطبيعة أعطتني النتائج المنشودة رغم تقلبات الطقس والحساسية المعروفة. وفي نهاية المطاف أرى نفسي مدمن على صفحتي المعدلة؛ فإذا كنتم تعانون مثل حالتي فالبحث انتهى هنا!

  5. Alice Perry

    After a few weeks of daily use, my skin looks more balanced. I’ve noticed less midday shine, fewer angry spots, and an overall smoother texture.

  6. Beatriz Rio de Janeiro, Brasil

    Usei o sérum por algumas semanas e notei que acalma a acne rápido. O tamanho da embalagem é bom, mas veio um pouco amassada. Funciona de verdade na oleosidade também.

  7. Joaquín Barcelona, España

    Compré el sérum hace unas semanas. Se siente ligero al aplicarlo. Me calmó la piel rápidamente y ayudó con mi acné. Noté que reduce un poco el aceite, aunque llegó algo más tarde de lo que pensé.
