Mụn ở cằm là tình trạng khá khó chịu vì thường gây đau nhức và tái phát nhiều lần. Thậm chí, mụn ở cằm có thể len lỏi dọc theo đường viền hàm và sinh sôi nhanh chóng trong một đêm. Đây là tình trạng liên quan đến nội tiết tố trên da của người mắc phải.
1. Tình trạng mụn ở cằm là bệnh gì?
Theo các chuyên gia da liễu, mụn ở cằm phần lớn là do rối loạn nội tiết tố và di truyền.
Mụn ở cằm ảnh hưởng đến phụ nữ nhiều hơn nam giới. Phụ nữ bị mụn sau 23 tuổi thường chủ yếu xuất hiện ở cằm, quai hàm và xung quanh má dưới. Thực tế là mụn trứng cá ở cằm xảy ra ở phụ nữ trưởng thành khác nhiều so với ở tuổi thiếu niên.
Mụn ở cằm thường biểu hiện dưới dạng mụn nang (mụn đỏ, lớn) hoặc nốt sần (mụn đầu trắng không bao giờ vỡ trên bề mặt), do sự gia tăng sản xuất dầu tự nhiên bên trong cằm. dưới da.
Thông thường, da sẽ tiết ra một lớp dầu mỏng, phân bố trên bề mặt giúp phần này luôn mịn màng, căng bóng. Tuy nhiên, khi dầu được sản xuất quá mức, dầu thừa có thể kết hợp với các mảnh vụn khác trên bề mặt da để làm tắc nghẽn lỗ chân lông. Đây là nguyên nhân gây ra mụn trứng cá.
Một điều kiện thuận lợi nữa là cằm cũng là vùng mà mọi người rất dễ tiếp xúc, ví dụ như đưa tay lên mặt, khiến bụi bẩn nhiều hơn và làm lan rộng dầu, bã nhờn.
Các chuyên gia da liễu cũng khuyến cáo, dù mụn ở cằm do nguyên nhân nào thì cũng nên để nguyên và không nên nặn.
2. Nguyên nhân nào gây ra mụn ở cằm?
2.1 Rối loạn nội tiết liên quan đến chu kỳ kinh nguyệt
Theo các chuyên gia da liễu, mụn trứng cá ở cằm có xu hướng xuất hiện vào nửa sau của chu kỳ hoặc thời kỳ tiền kinh nguyệt – ngay trước khi đến kỳ kinh nguyệt. Điều này được giải thích là do trong nửa đầu của chu kỳ, lượng estrogen trong máu tăng lên và trong nửa sau (từ ngày 14 đến ngày 28) lượng progesterone sẽ chiếm ưu thế để thay thế nó. Lúc này, cơ thể cũng sản sinh ra nhiều testosterone, một loại hormone làm tăng kích thước và hoạt động của tuyến dầu trên da. Điều này đồng nghĩa với việc tuyến dầu trở nên lớn hơn, lỗ chân lông bị tắc nghẽn nhiều hơn. Kết quả là có nhiều không gian hơn cho vi khuẩn xâm nhập và tạo ra các nốt mụn trên da.
2.2 Do rối loạn giấc ngủ
Theo một nghiên cứu gần đây, nguy cơ bị căng thẳng tâm lý tăng 14% cho mỗi giờ mất ngủ trong một đêm. Điều này có thể dẫn đến những bất thường trong cấu trúc và chức năng của da.
Một yếu tố khác kết nối tình trạng thiếu ngủ với sự hình thành mụn trứng cá là sự đề kháng insulin tăng lên. Tình trạng mụn này được giải thích là do tình trạng kháng insulin có thể làm tăng lượng glucose trong máu – một trong những nguyên nhân chính gây ra mụn.
Mặt khác, căng thẳng cả về tâm lý và thể chất sẽ làm tăng nồng độ hormone căng thẳng (cortisol) trong cơ thể. Vì vậy, khi bạn không ngủ đủ giấc, làn da của bạn sẽ trông xỉn màu, không được căng mọng và tươi tắn. Hơn nữa, cortisol là một loại hormone cũng đóng một vai trò trong việc sản xuất bã nhờn – vì vậy da dễ nổi mụn hơn.
