長斑就(jiu)是一個很令人煩(fan)惱的(de)(de)問題，大部分都是長(chang)在(zai)面部較多，比較顯眼的(de)(de)位置。長(chang)在(zai)臉上也十分影響心情，甚(shen)至會(hui)遇到(dao)交際問題。

 

斑也分為定性斑和活性斑：

 

活(huo)性斑(ban)(ban)(ban)(ban)(ban)(ban)：黃(huang)褐(he)斑(ban)(ban)(ban)(ban)(ban)(ban)、角化斑(ban)(ban)(ban)(ban)(ban)(ban)、額頭斑(ban)(ban)(ban)(ban)(ban)(ban)、腎恐斑(ban)(ban)(ban)(ban)(ban)(ban)、肝斑(ban)(ban)(ban)(ban)(ban)(ban)、脾斑(ban)(ban)(ban)(ban)(ban)(ban)、眼周斑(ban)(ban)(ban)(ban)(ban)(ban)、蝴蝶斑(ban)(ban)(ban)(ban)(ban)(ban)、反(fan)彈(dan)斑(ban)(ban)(ban)(ban)(ban)(ban)、曬斑(ban)(ban)(ban)(ban)(ban)(ban)、唇上(shang)斑(ban)(ban)(ban)(ban)(ban)(ban)、妊(ren)娠(shen)斑(ban)(ban)(ban)(ban)(ban)(ban)、激素(su)斑(ban)(ban)(ban)(ban)(ban)(ban)、膽斑(ban)(ban)(ban)(ban)(ban)(ban)。

 

定性斑(ban)：雀(que)斑(ban)、老年斑(ban)、真皮斑(ban)、點(dian)狀黃(huang)褐(he)斑(ban)。

 

黑色(se)素的(de)含量也是皮(pi)(pi)膚(fu)顏色(se)的(de)主要(yao)因素，也就(jiu)意味著斑的(de)顏色(se)深淺也是尤其決定(ding)的(de)。此外，膚(fu)色(se)還受皮(pi)(pi)膚(fu)表皮(pi)(pi)角質層的(de)厚薄(bo)(bo)、表皮(pi)(pi)透明(ming)層及顆粒層的(de)厚薄(bo)(bo)影響。若(ruo)角質層較厚，則(ze)皮(pi)(pi)膚(fu)偏黃色(se)；顆粒層和透明(ming)層厚，皮(pi)(pi)膚(fu)則(ze)顯白(bai)色(se)。

 

據目前臨床研(yan)究發現，日曬、日光是(shi)對(dui)黑(hei)素(su)代謝影響最大(da)的外部(bu)因素(su)，紫外線可使表皮內的黑(hei)素(su)小(xiao)體迅速重新分布,將(jiang)黑(hei)素(su)集中到日曬部(bu)位。

研究發現，神(shen)經因素(su)(su)同(tong)樣會影響黑素(su)(su)代謝，長期(qi)處于精神(shen)緊張、疲勞(lao)甚(shen)至是(shi)失眠的狀況，將(jiang)影響人體的神(shen)經功能及腎上腺皮脂功能，激(ji)發斑(ban)的形成(cheng)。
