Sự hình thành của mụn “đầu đen” và mụn bọc

(Dân trí) - Mụn đầu đen và mụn bọc hình thành tại những thời điểm khác nhau khi da bị viêm nhiễm. Khi mụn chạc lên tức là da đã bị viêm rất nặng. Một vài loại viêm da có thể tự khỏi nhưng một số lại có chiều hướng xấu đi.

Sự hình thành mụn

Tất cả mụn trứng cá sẽ xuất hiện khi dầu bị tắc lại ở nang lông hay lỗ chân lông, tạo môi trường lý tưởng cho vi khuẩn sinh sôi. Hai loại mụn trứng cá do vi khuẩn tạo thành chính là: Mụn đầu trắng và mụn đầu đen.

Biểu hiện bên ngoài

Mụn đầu trắng xuất hiện khi dầu bị tắc lại và vi khuẩn ‘hoành hành” dưới bề mặt da, các đốm trắng sau đó sẽ xuất hiện, những đốm này thường rất nhỏ và đôi khi ta không thể nhìn thấy chúng. Mụn đầu đen là có sự xuất hiện của melamin và nang lông mở. Melanin, một hợp chất tạo màu da, làm ôxy hóa da và làm cho mụn có màu nâu hoặc màu đen.

Quá trình

Mụn đầu đen và đầu trắng thường chỉ giải phóng dầu và vi khuẩn tới bề mặt và bắt đầu quá trình hàn gắn vết thương. Nếu vách nang lông đã thủng, mụn đầu trắng và đầu đen sẽ mọc lên và trở thành loại mụn có khả năng gây viêm nhiễm và xuất hiện mủ bao quanh, tạo thành mụn bọc.

Sờ hoặc cậy mụn đầu đen cũng có thể tạo ra mủ hoặc các nốt mụn bọc.

Cách phòng trị

Để ngăn chăn sự bùng phát của cả mụn đầu đen và mụn bọc, cần luôn giữ cho da luôn sạch sẽ.

Sử dụng khăn mặt sạch và lau mặt nhẹ nhàng.

Đừng dùng tay sờ lên mặt và lên các nốt mụn.

Sử dụng các loại mỹ phẩm không chứa dầu và gặp bác sỹ da liễu để được tư vấn và kê các loại thuốc trị mụn an toàn cho da..
