Red marks are vascular dilation, brown marks are pigmentation – different lasers for different types. Rappoel combines vascular and pigment lasers for precise acne mark removal<\/div>\n<\/p><\/div>\n<p>After acne heals, many people find colored marks left behind: red, brown, dark brown – collectively called “post-acne marks.” Red marks are post-inflammatory erythema (PIE) from capillary dilation, while brown marks are post-inflammatory hyperpigmentation (PIH) from excess melanin. The causes are entirely different, requiring different laser types for targeted treatment. Rappoel Dermatology near Gangnam Station, Seoul, uses a combined vascular + pigment laser approach, precisely targeting different colored marks for clear, even skin tone.<\/p>\n<h2>Two Types of Acne Marks<\/h2>\n<table>\n<tr>\n<th>Type<\/th>\n<th>Appearance<\/th>\n<th>Cause<\/th>\n<th>Duration<\/th>\n<th>Treatment<\/th>\n<\/tr>\n<tr>\n<td>PIE (Post-inflammatory Erythema)<\/td>\n<td>Pink to red<\/td>\n<td>Inflammation causes capillary dilation<\/td>\n<td>3-6 months<\/td>\n<td>Vascular laser<\/td>\n<\/tr>\n<tr>\n<td>PIH (Post-inflammatory Hyperpigmentation)<\/td>\n<td>Light brown to dark brown<\/td>\n<td>Inflammation triggers excess melanin<\/td>\n<td>6-12 months<\/td>\n<td>Pigment laser<\/td>\n<\/tr>\n<\/table>\n<h2>Red Marks (PIE): Vascular Laser Approach<\/h2>\n<ul>\n<li><strong>Principle:<\/strong> Specific wavelengths (e.g., 585\/595nm) selectively absorbed by hemoglobin, coagulating and shrinking dilated capillaries<\/li>\n<li><strong>Common devices:<\/strong> Pulsed Dye Laser (PDL), long-pulsed Nd:YAG 1064nm<\/li>\n<li><strong>Sensation:<\/strong> Mild sting like a rubber band snap on skin<\/li>\n<li><strong>Post-treatment:<\/strong> Mild redness resolves in hours, possible slight purpura resolves in 5-7 days<\/li>\n<li><strong>Sessions:<\/strong> Red marks typically improve significantly after 3-4 sessions (4-week intervals)<\/li>\n<\/ul>\n<h2>Brown Marks (PIH): Pigment Laser Approach<\/h2>\n<ul>\n<li><strong>Principle:<\/strong> Specific wavelengths selectively absorbed by melanin, fragmenting pigment particles<\/li>\n<li><strong>Common devices:<\/strong> Picosecond laser (755nm\/1064nm), Q-switched Nd:YAG<\/li>\n<li><strong>Sensation:<\/strong> Mild sting, short treatment time<\/li>\n<li><strong>Post-treatment:<\/strong> Darkening slightly (crusting phase), lightening after crust falls off in 5-7 days<\/li>\n<li><strong>Sessions:<\/strong> Brown marks typically improve after 4-6 sessions (4-week intervals)<\/li>\n<\/ul>\n<h2>Combined Approach: Type-Specific Treatment for Mixed Marks<\/h2>\n<ol>\n<li><strong>Assessment:<\/strong> Physician carefully evaluates mark colors, distinguishing PIE vs. PIH proportions<\/li>\n<li><strong>Zone-specific treatment:<\/strong> Vascular laser for red areas, pigment laser for brown areas, in the same session<\/li>\n<li><strong>Alternating treatment:<\/strong> Vascular and pigment lasers alternate across different areas in one visit<\/li>\n<li><strong>Rejuran synergy:<\/strong> Post-laser Rejuran PDRN accelerates inflammation resolution and barrier repair<\/li>\n<li><strong>Sun protection:<\/strong> SPF50+ PA++++ is the most critical post-care for all mark treatments<\/li>\n<\/ol>\n<h2>Acne Marks vs. Acne Scars<\/h2>\n<ul>\n<li><strong>Acne marks (flat):<\/strong> Skin surface is flat, only color change – red or brown, laser treatment is effective<\/li>\n<li><strong>Acne scars (depressed):<\/strong> Skin surface has indentations – ice pick, boxcar, rolling, requiring Rejuran PDRN or deep laser treatment<\/li>\n<li><strong>Mixed type:<\/strong> Both flat marks and depressed scars, requiring combined approach<\/li>\n<\/ul>\n<p>Rappoel Dermatology is located 3 minutes from Gangnam Station Exit 10. Our physicians carefully assess your mark type – PIE-dominant, PIH-dominant, or mixed – to create a personalized combined laser plan. Treatment is comfortable, ~30 minutes per session, with normal activities afterward. With daily sun protection and repair care, significant improvement is typically seen after 3-6 sessions.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Which is easier to remove – red or brown acne marks?<\/div>\n<div class=\"faq-a\">Red marks (PIE) are typically easier to remove than brown marks (PIH). Red marks are vascular dilation, usually improving significantly with vascular laser in 3-4 sessions. Brown marks are pigmentation, requiring 4-6 pigment laser sessions. However, many patients have mixed type (both red and brown), requiring combined approach. Rappoel physicians assess your mark type for zone-specific treatment.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can laser acne mark removal cause scarring or rebound?<\/div>\n<div class=\"faq-a\">Properly performed laser treatment does not cause scarring. Post-treatment pigmentation may temporarily darken (especially brown marks) as pigment particles are fragmented – this is normal, lightening after crust sheds in 5-7 days. Sun protection (SPF50+ PA++++) is critical as UV is the biggest factor in pigmentation rebound. Rappoel physicians select laser parameters appropriate for your skin tone and mark type to minimize post-treatment hyperpigmentation risk.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many sessions until I see results?<\/div>\n<div class=\"faq-a\">Red marks typically start fading after 2-3 sessions, largely resolved after 3-4. Brown marks improve after 3-4 sessions, significantly lighter after 4-6. Sessions are 4 weeks apart. Mixed marks require combined approach, possibly 5-8 sessions total. Rejuran PDRN synergy accelerates improvement. Daily sun protection is the most important adjunctive measure.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can I wear makeup after laser acne mark treatment?<\/div>\n<div class=\"faq-a\">Avoid makeup for 24 hours post-treatment to let skin recover. Light makeup is fine after 24 hours, avoiding heavy foundation. Avoid acid-based skincare (AHA, BHA, retinol) for one week.

Red marks are vascular dilation, brown marks are pigmentation – different lasers for different types. Rappoel combines vascular and pigment lasers for precise acne mark removal<\/div>\n<\/p><\/div>\n<p>After acne heals, many people find colored marks left behind: red, brown, dark brown – collectively called “post-acne marks.” Red marks are post-inflammatory erythema (PIE) from capillary dilation, while brown marks are post-inflammatory hyperpigmentation (PIH) from excess melanin. The causes are entirely different, requiring different laser types for targeted treatment. Rappoel Dermatology near Gangnam Station, Seoul, uses a combined vascular + pigment laser approach, precisely targeting different colored marks for clear, even skin tone.<\/p>\n<h2>Two Types of Acne Marks<\/h2>\n<table>\n<tr>\n<th>Type<\/th>\n<th>Appearance<\/th>\n<th>Cause<\/th>\n<th>Duration<\/th>\n<th>Treatment<\/th>\n<\/tr>\n<tr>\n<td>PIE (Post-inflammatory Erythema)<\/td>\n<td>Pink to red<\/td>\n<td>Inflammation causes capillary dilation<\/td>\n<td>3-6 months<\/td>\n<td>Vascular laser<\/td>\n<\/tr>\n<tr>\n<td>PIH (Post-inflammatory Hyperpigmentation)<\/td>\n<td>Light brown to dark brown<\/td>\n<td>Inflammation triggers excess melanin<\/td>\n<td>6-12 months<\/td>\n<td>Pigment laser<\/td>\n<\/tr>\n<\/table>\n<h2>Red Marks (PIE): Vascular Laser Approach<\/h2>\n<ul>\n<li><strong>Principle:<\/strong> Specific wavelengths (e.g., 585\/595nm) selectively absorbed by hemoglobin, coagulating and shrinking dilated capillaries<\/li>\n<li><strong>Common devices:<\/strong> Pulsed Dye Laser (PDL), long-pulsed Nd:YAG 1064nm<\/li>\n<li><strong>Sensation:<\/strong> Mild sting like a rubber band snap on skin<\/li>\n<li><strong>Post-treatment:<\/strong> Mild redness resolves in hours, possible slight purpura resolves in 5-7 days<\/li>\n<li><strong>Sessions:<\/strong> Red marks typically improve significantly after 3-4 sessions (4-week intervals)<\/li>\n<\/ul>\n<h2>Brown Marks (PIH): Pigment Laser Approach<\/h2>\n<ul>\n<li><strong>Principle:<\/strong> Specific wavelengths selectively absorbed by melanin, fragmenting pigment particles<\/li>\n<li><strong>Common devices:<\/strong> Picosecond laser (755nm\/1064nm), Q-switched Nd:YAG<\/li>\n<li><strong>Sensation:<\/strong> Mild sting, short treatment time<\/li>\n<li><strong>Post-treatment:<\/strong> Darkening slightly (crusting phase), lightening after crust falls off in 5-7 days<\/li>\n<li><strong>Sessions:<\/strong> Brown marks typically improve after 4-6 sessions (4-week intervals)<\/li>\n<\/ul>\n<h2>Combined Approach: Type-Specific Treatment for Mixed Marks<\/h2>\n<ol>\n<li><strong>Assessment:<\/strong> Physician carefully evaluates mark colors, distinguishing PIE vs. PIH proportions<\/li>\n<li><strong>Zone-specific treatment:<\/strong> Vascular laser for red areas, pigment laser for brown areas, in the same session<\/li>\n<li><strong>Alternating treatment:<\/strong> Vascular and pigment lasers alternate across different areas in one visit<\/li>\n<li><strong>Rejuran synergy:<\/strong> Post-laser Rejuran PDRN accelerates inflammation resolution and barrier repair<\/li>\n<li><strong>Sun protection:<\/strong> SPF50+ PA++++ is the most critical post-care for all mark treatments<\/li>\n<\/ol>\n<h2>Acne Marks vs. Acne Scars<\/h2>\n<ul>\n<li><strong>Acne marks (flat):<\/strong> Skin surface is flat, only color change – red or brown, laser treatment is effective<\/li>\n<li><strong>Acne scars (depressed):<\/strong> Skin surface has indentations – ice pick, boxcar, rolling, requiring Rejuran PDRN or deep laser treatment<\/li>\n<li><strong>Mixed type:<\/strong> Both flat marks and depressed scars, requiring combined approach<\/li>\n<\/ul>\n<p>Rappoel Dermatology is located 3 minutes from Gangnam Station Exit 10. Our physicians carefully assess your mark type – PIE-dominant, PIH-dominant, or mixed – to create a personalized combined laser plan. Treatment is comfortable, ~30 minutes per session, with normal activities afterward. With daily sun protection and repair care, significant improvement is typically seen after 3-6 sessions.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Which is easier to remove – red or brown acne marks?<\/div>\n<div class=\"faq-a\">Red marks (PIE) are typically easier to remove than brown marks (PIH). Red marks are vascular dilation, usually improving significantly with vascular laser in 3-4 sessions. Brown marks are pigmentation, requiring 4-6 pigment laser sessions. However, many patients have mixed type (both red and brown), requiring combined approach. Rappoel physicians assess your mark type for zone-specific treatment.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can laser acne mark removal cause scarring or rebound?<\/div>\n<div class=\"faq-a\">Properly performed laser treatment does not cause scarring. Post-treatment pigmentation may temporarily darken (especially brown marks) as pigment particles are fragmented – this is normal, lightening after crust sheds in 5-7 days. Sun protection (SPF50+ PA++++) is critical as UV is the biggest factor in pigmentation rebound. Rappoel physicians select laser parameters appropriate for your skin tone and mark type to minimize post-treatment hyperpigmentation risk.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many sessions until I see results?<\/div>\n<div class=\"faq-a\">Red marks typically start fading after 2-3 sessions, largely resolved after 3-4. Brown marks improve after 3-4 sessions, significantly lighter after 4-6. Sessions are 4 weeks apart. Mixed marks require combined approach, possibly 5-8 sessions total. Rejuran PDRN synergy accelerates improvement. Daily sun protection is the most important adjunctive measure.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can I wear makeup after laser acne mark treatment?<\/div>\n<div class=\"faq-a\">Avoid makeup for 24 hours post-treatment to let skin recover. Light makeup is fine after 24 hours, avoiding heavy foundation. Avoid acid-based skincare (AHA, BHA, retinol) for one week. Sun protection is the most critical post-care – SPF50+ PA++++ daily reapplication. Rappoel provides detailed post-care instructions.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is it convenient to get acne mark laser at Gangnam Station Rappoel?<\/div>\n<div class=\"faq-a\">Very convenient.
