preventing the collagen and elastin structures from fully repairing themselves. As a result, the damaged area sinks below the surrounding skin surface, creating unsightly pits.<\/p>\n<p style=\"text-align: justify;\">Pockmarked scars often form after:<\/p>\n<ul>\n<li style=\"text-align: justify;\">Severe inflammatory acne<\/li>\n<li style=\"text-align: justify;\">Chickenpox<\/li>\n<li style=\"text-align: justify;\">Accidents, surgery<\/li>\n<li style=\"text-align: justify;\">Improper acne extraction or prolonged infection<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Depending on the extent of the damage and how the skin heals, pitted scars can appear in various forms.<\/p>\n<figure id=\"attachment_7256\" aria-describedby=\"caption-attachment-7256\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-7256\" src=\"https:\/\/hbioclinic.com.vn\/wp-content\/uploads\/2026\/04\/seo-lom-hinh-thanh-do-mun-viem-nang.jpg\" alt=\"S\u1eb9o l\u00f5m h\u00ecnh th\u00e0nh do m\u1ee5n vi\u00eam n\u1eb7ng\" width=\"600\" height=\"750\" \/><figcaption id=\"caption-attachment-7256\" class=\"wp-caption-text\">Pitted scars form due to severe acne inflammation<\/figcaption><\/figure>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Classification_of_Common_Types_of_Depressed_Scars\"><\/span><strong>Classification of Common Types of Depressed Scars<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Below are the most common types of depressed scars, each with its own characteristics.

This type of scar often forms after prolonged inflammatory acne, chickenpox, or skin injuries that were not properly treated.<\/p>\n<figure id=\"attachment_7255\" aria-describedby=\"caption-attachment-7255\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-7255\" src=\"https:\/\/hbioclinic.com.vn\/wp-content\/uploads\/2026\/04\/seo-day-vuong.jpg\" alt=\"S\u1eb9o \u0111\u00e1y vu\u00f4ng\" width=\"600\" height=\"313\" \/><figcaption id=\"caption-attachment-7255\" class=\"wp-caption-text\">Square-bottomed scars<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Depending on the severity, square-bottomed scars can be shallow or deep, appearing scattered or clustered in areas, making the skin surface less smooth and uneven in color. When light shines on them, the scar edges become more visible, making the skin look rough and older than its age. Compared to pointed-bottomed scars, square-bottomed scars have a better chance of improvement if treated correctly and at the right time.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Round-bottomed_scars\"><\/span><em><strong>Round-bottomed scars<\/strong><\/em><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Round-bottomed scars (Rolling Scars) have a wide opening, a rounded base, no clearly defined sharp edges, and are often distributed in patches on the skin, especially on the cheeks. Round-bottomed scars form due to damage to the connective tissue under the skin, when fibrous strands pull the skin surface down and hinder the natural collagen regeneration process.<\/p>\n<p style=\"text-align: justify;\">Because they are not as deep as pointed-bottomed scars but spread widely, round-bottomed scars make the skin less firm, look older than its age, and are easily visible when light shines at an angle. To effectively improve round-bottomed scars, it is necessary to directly target the fibrous strands under the skin to release the scar surface and stimulate collagen production.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Ice_Pick_Scars\"><\/span><em><strong>Ice Pick Scars<\/strong><\/em><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Ice pick scars are one of the most severe and difficult types of pitted scars to treat. These scars are small (usually &lt; 2mm) but penetrate deep into the skin, with a narrow opening and a pointed base, resembling a sharp object piercing the skin.<\/p>\n<p style=\"text-align: justify;\">Ice pick scars often form after severe acne such as cystic acne or pustules, or due to improper acne squeezing habits that cause deep tissue damage and prevent complete self-regeneration. Because of their significant depth and narrow structure, topical products are generally ineffective in providing noticeable improvement.<\/p>\n<figure id=\"attachment_7254\" aria-describedby=\"caption-attachment-7254\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-7254\" src=\"https:\/\/hbioclinic.com.vn\/wp-content\/uploads\/2026\/04\/seo-day-nhon.jpg\" alt=\"S\u1eb9o \u0111\u00e1y nh\u1ecdn\" width=\"600\" height=\"450\" \/><figcaption id=\"caption-attachment-7254\" class=\"wp-caption-text\">Sharp-bottomed scars<\/figcaption><\/figure>\n<p>Scars make the skin surface rough, less smooth, easily visible under light, and almost impossible to conceal with makeup.

This method is very suitable for rolling scars and deep boxcar scars, where the fibrous roots pull the skin down, causing the surface to be concave.<\/p>\n<p style=\"text-align: justify;\">Subcision helps to flatten the skin surface, creating conditions for more effective collagen regeneration.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Microneedling\"><\/span><em><strong>Microneedling<\/strong><\/em><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Microneedling creates micro-injuries on the skin to stimulate the self-healing mechanism and increase collagen production. This method is suitable for shallow to medium-sized indented scars and mixed scars, helping to gradually fill in the skin surface and improve smoothness.<\/p>\n<p style=\"text-align: justify;\">When combined with other advanced methods such as subcision, TCA cross, or laser, microneedling optimizes treatment results and enhances overall effectiveness.<\/p>\n<figure id=\"attachment_7252\" aria-describedby=\"caption-attachment-7252\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-7252\" src=\"https:\/\/hbioclinic.com.vn\/wp-content\/uploads\/2026\/04\/lan-kim-vi-kim-microneedling-1200x800.jpg\" alt=\"L\u0103n kim \/ Vi kim (Microneedling)\" width=\"600\" height=\"400\" \/><figcaption id=\"caption-attachment-7252\" class=\"wp-caption-text\">Microneedling<\/figcaption><\/figure>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Effective_Treatment_Solutions_for_Pitted_Scars_at_HBIO_Clinic\"><\/span><strong>Effective Treatment Solutions for Pitted Scars at HBIO Clinic<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">If you are looking for a safe and effective way to improve pitted scars, HBIO Clinic is a reputable address with a team of specialized doctors and personalized treatment plans.
