سلام حبيبتي كيفك الكولاجين شي بيعقد الصراحة، ما شاء الله تأثيره سريع حسيت على جسمي، غير الكولاجين يلي كنت مستعملته من قبل، يعني زيادة على تأثيره بوجهي يلي لاحظته من أول أسبوع، مبسوطة كتير بالنشاط يلي عم يعطيني إياه، حتى ما عدت عم حس بوجع بعضلاتي متل قبل، أنا لأن بمارس الرياضة كنت عاني من هيدا الموضوع، وحتى ما شاء الله بحس بطاقة كنت فاقدتها إلي فترة الحمد لله 🙌🏼 يعني أبدعت الصراحة الدكتورة فاطمة، إلى مزيد من التألق 🤍

صارلي شهر عم آخذ الكولاجين. أكثر شي فرق معي أني حاسس معدتي resilient أكثر. هيدا غير التحسن بمستوى النشاط اليومي.

أول شي بلش بالضفاير صاروا أسمك واللمعة
الشعر خف الهر منيح
البشرة، أنا بالعادة بالبرد كتير بتنشف بشرتي في تحسن بس خفيف بعدو
