長斑就是一個很令人煩惱的問(wen)題,大部分都是長在(zai)面部較多,比較顯眼的位置。長在(zai)臉(lian)上也十分影響(xiang)心情,甚至會遇(yu)到(dao)交際問(wen)題。
斑也分為定性斑和活性斑:
活性(xing)斑(ban)(ban)(ban)(ban)(ban):黃褐斑(ban)(ban)(ban)(ban)(ban)、角(jiao)化斑(ban)(ban)(ban)(ban)(ban)、額頭(tou)斑(ban)(ban)(ban)(ban)(ban)、腎(shen)恐斑(ban)(ban)(ban)(ban)(ban)、肝(gan)斑(ban)(ban)(ban)(ban)(ban)、脾斑(ban)(ban)(ban)(ban)(ban)、眼周斑(ban)(ban)(ban)(ban)(ban)、蝴蝶斑(ban)(ban)(ban)(ban)(ban)、反彈(dan)斑(ban)(ban)(ban)(ban)(ban)、曬斑(ban)(ban)(ban)(ban)(ban)、唇上斑(ban)(ban)(ban)(ban)(ban)、妊(ren)娠斑(ban)(ban)(ban)(ban)(ban)、激素(su)斑(ban)(ban)(ban)(ban)(ban)、膽斑(ban)(ban)(ban)(ban)(ban)。
定性斑(ban):雀(que)斑(ban)、老年斑(ban)、真皮斑(ban)、點狀黃(huang)褐斑(ban)。
黑(hei)色(se)素(su)(su)的(de)含量也(ye)是皮膚(fu)(fu)顏(yan)色(se)的(de)主要因素(su)(su),也(ye)就意(yi)味著斑(ban)的(de)顏(yan)色(se)深(shen)淺也(ye)是尤(you)其決(jue)定(ding)的(de)。此外,膚(fu)(fu)色(se)還受皮膚(fu)(fu)表(biao)皮角質層(ceng)的(de)厚薄(bo)、表(biao)皮透明(ming)層(ceng)及顆(ke)粒(li)層(ceng)的(de)厚薄(bo)影(ying)響(xiang)。若角質層(ceng)較厚,則(ze)皮膚(fu)(fu)偏黃色(se);顆(ke)粒(li)層(ceng)和透明(ming)層(ceng)厚,皮膚(fu)(fu)則(ze)顯(xian)白色(se)。
據目前臨(lin)床研究發現(xian),日(ri)曬(shai)、日(ri)光是對(dui)黑素代(dai)謝影響最大(da)的(de)外部(bu)因素,紫外線可(ke)使表皮內(nei)的(de)黑素小體迅速重新分布,將黑素集(ji)中到日(ri)曬(shai)部(bu)位。
研究(jiu)發現(xian),神(shen)經因素(su)同樣會影響黑(hei)素(su)代謝,長(chang)期(qi)處于精神(shen)緊張(zhang)、疲勞甚(shen)至(zhi)是失眠的(de)狀況,將影響人(ren)體的(de)神(shen)經功能(neng)(neng)及腎上腺皮脂功能(neng)(neng),激發斑的(de)形成(cheng)。
