However the skin is protected by the sebum barrier. Acne occurs when too much sebum is produced. However, there would be problems with dry skin and possibly conditions such as rhagades if too little sebum is produced. Sebum is comprised of a range of aliphatic compounds and has the role of maintaining the moisture level of the skin.<\/br>\r\n\r\n<h2>1. The function of sebum<\/h2>\r\n<br>Sebum is one of the lipid components that sebocytes produce with the main components being triglycerides. Sebum is released from the sebaceous glands, transported to the surface of the skin through the pores and providing a sebum barrier by mixture with sweat.<\/br> <img decoding=\"async\" loading=\"lazy\" class=\"wp-image-221 alignright\" src=\"https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_01-759x1024.jpg\" alt=\"\" width=\"207\" height=\"279\" srcset=\"https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_01-759x1024.jpg 759w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_01-222x300.jpg 222w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_01-768x1036.jpg 768w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_01.jpg 958w\" sizes=\"(max-width: 207px) 100vw, 207px\" \/>\r\n\r\n<br>The sebum barrier maintains moisture and provides smoothness of the skin and hair. Moreover, the lipids contained in sebum are decomposed by resident bacteria on the skin producing fatty acids. These fatty acids increase the protective capability of the skin by producing a mild acidity that is an unsuitable environment for pathogenic bacteria to propagate.<\/br>\r\n\r\n<br>The function of sebum in the skin<\/br>\r\n<ul class=\"noline\">\r\n \t<li>brings moisture, flexibility and smoothness to the skin<\/li>\r\n \t<li>prevents the stratum corneum from peeling off<\/li>\r\n \t<li>prevents water evaporation<\/li>\r\n \t<li>bactericidal action<\/li>\r\n<\/ul>\r\n<h2>2. Decrease of sebum and skin functions<\/h2>\r\n<br>The secretion of sebum decreases due to various factors such as stress, aging, dry air, soap and detergent. As a result, an adequate sebum barrier is not produced making exogenous irritation or infection easier. If the skin is injured, water evaporation from the skin is promoted, leading to skin metabolism disorders and problems such as dry and wrinkled skin. A decrease in sebum secretion also causes skin disorders, such as pruritus and pain.<\/br>\r\n\r\n<img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"485\" class=\"alignnone size-large wp-image-222\" src=\"https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_02-1024x485.jpg\" alt=\"\" srcset=\"https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_02-1024x485.jpg 1024w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_02-300x142.jpg 300w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_02-768x364.jpg 768w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_02-1536x728.jpg 1536w, https:\/\/heimat-ltd.com\/vn\/wp-content\/uploads\/research_sebum_02-2048x970.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\r\n<div class=\"details_box\">\r\n<h2>3. Balance of sebum<\/h2>\r\n<br>Maintaining a healthy balance in the production of sebum by the sebaceous glands is crucial for the health of the epidermis. Supplying sebum from outside can also help. However, maintaining the ability for natural sebum production is more ideal as sebum is produced within the body.
