3 Key Reasons Why Lasers Can’t Remove White Scars - Insights from International White Scar Experts

1. White Scars: The Final Stage of Scar Maturation

If a wound only affects the superficial epidermis, proper care will usually prevent noticeable scarring. However, if the damage reaches the dermis, the situation becomes more complicated. The dermis is rich in collagen, which proliferates during the healing process. If this proliferation is excessive and disorganized, it results in raised, red scars that are different in texture and appearance from normal skin and can cause pain and itching. Even after healing, the scar undergoes various color changes.

“White scars are the final color of mature scars,” says Dr. Su-Ben Tsao. Initially, a healing wound appears red and becomes raised within three months. With proper care, these raised scars flatten within 3 to 6 months, changing from red to pink, brown, and finally blending with the natural skin tone. If the melanocytes in the wound area secrete abnormally, resulting in insufficient or absent pigment, the affected area becomes lighter in color, forming a white scar, which is the scar’s final form.

2. Current Cosmetic Treatments Can’t Truly Remove White Scars

Common treatments like dermabrasion, scar revision, scar injections, and laser therapy cannot effectively remove white scars. Dr. Su-Ben Tsao explains that while tattoos, UV exposure, and makeup can mask the appearance of white scars, they cannot completely blend with the surrounding skin tone and may even darken the normal skin, making it look more unnatural.

3. A New Treatment Method: White Scar Color Regeneration

To truly bid farewell to stubborn white scars, a new treatment method called “White Scar Color Regeneration” is needed. This procedure involves taking a small piece of the patient’s skin, removing subcutaneous fat and superficial epidermis, cutting it into 1–2 cm micro skin grafts containing melanocytes, and implanting them into the white scar using an 18-gauge needle. This promotes the regeneration of the damaged area, gradually restoring the normal skin color within 3 to 6 months post-surgery. If the white scar is raised, it is recommended to undergo scar flattening surgery first, and then, after a year, proceed with White Scar Color Regeneration.

Dr. Su-Ben Tsao points out that although white scars are not painful or itchy, they may conceal personal stories that individuals prefer to keep private, such as tattoos, self-harm, or reconstructive surgeries like cleft lip and palate repair. Once these scars form into white scars, they inevitably impact one’s life and psychological state. Therefore, using White Scar Color Regeneration to restore the original skin color can not only improve appearance but also boost social confidence.

3大原因，

國際白疤專家解答為什麼雷射除不了白疤？

1. 白色疤痕是成熟疤痕的最終顏色

如果傷口只在淺層表皮，經過妥善照顧後，癒合後不會留下明顯疤痕。但如果傷害擴及到真皮層，情況就變得複雜了。真皮層中有豐富的膠原蛋白組織，在傷口癒合過程中會不斷增生，如果增生過量且排列凌亂，就會形成突起、紅腫的疤痕，外觀和觸感都不同於正常皮膚，甚至會有疼痛、搔癢等不適感。即使癒合後，疤痕的顏色也會經歷多次變化。

曹賜斌醫師指出，「白色疤痕就是成熟疤痕的最終顏色。」初期癒合的傷口通常呈現紅色，在三個月內會增生突起，若能正確護理，這種突起的疤痕會在3到6個月內逐漸平坦，由紅色轉變為粉色、褐色，最終趨近於自然膚色。如果黑色素細胞分泌異常，導致局部色素分泌不足或缺失，則會形成白色的「白疤」，這是疤痕的最終形態。

2. 目前的美容方法無法真正去除白疤

一般來說，坊間的磨皮、修疤、消疤針和雷射光療等美容方法都無法真正去除白疤。曹賜斌醫師解釋，雖然刺青紋身、紫外線照射、化妝遮瑕可以掩飾白疤的外觀，但無法修飾得與周圍正常膚色完全相同，有時甚至會讓正常皮膚的顏色變深，顯得更加不自然。

3. 新的治療方法 — — 白疤顏色再生術

真正告別難纏白疤，需要全新的治療方法 — — 「白疤顏色再生術」。這種方法是取患者自身的一小片皮膚，去除皮下脂肪和淺表表皮後，切成約1到2厘米大小、含有色素細胞的顯微皮粒，再利用18號針頭植入白疤處，促使受損部位重新生成，術後3到6個月內逐漸恢復正常皮膚的顏色。如果白疤外觀突起，建議先進行疤痕整平手術，一年後疤痕平整，再進行「白疤顏色再生術」。

曹賜斌醫師指出，雖然白疤不痛不癢，但可能隱藏著個人不願透露的生活經歷，例如刺青、自殘或接受過整形或唇腭裂重建手術等。這樣的疤痕一旦形成白疤，難免影響生活和心理狀態。因此，利用「白疤顏色再生術」來恢復原本的膚色，不僅能改善外觀，還能提升社交自信。
