長斑就是(shi)一(yi)個很令人(ren)煩惱(nao)的問(wen)題,大部分都是(shi)長(chang)在(zai)面部較多,比(bi)較顯眼的位(wei)置。長(chang)在(zai)臉(lian)上也十(shi)分影響心情,甚(shen)至(zhi)會遇到交際問(wen)題。
斑也分為定性斑和活性斑:
活性斑(ban)(ban)(ban):黃(huang)褐(he)斑(ban)(ban)(ban)、角化斑(ban)(ban)(ban)、額頭斑(ban)(ban)(ban)、腎恐斑(ban)(ban)(ban)、肝(gan)斑(ban)(ban)(ban)、脾斑(ban)(ban)(ban)、眼周(zhou)斑(ban)(ban)(ban)、蝴蝶(die)斑(ban)(ban)(ban)、反(fan)彈(dan)斑(ban)(ban)(ban)、曬斑(ban)(ban)(ban)、唇上斑(ban)(ban)(ban)、妊娠斑(ban)(ban)(ban)、激素斑(ban)(ban)(ban)、膽斑(ban)(ban)(ban)。
定性斑(ban)(ban):雀(que)斑(ban)(ban)、老年斑(ban)(ban)、真皮斑(ban)(ban)、點狀黃褐斑(ban)(ban)。
黑色素的(de)含(han)量也(ye)是(shi)(shi)皮(pi)膚顏色的(de)主要因素,也(ye)就意味著斑的(de)顏色深淺也(ye)是(shi)(shi)尤(you)其(qi)決(jue)定(ding)的(de)。此外(wai),膚色還受皮(pi)膚表皮(pi)角(jiao)(jiao)質層(ceng)(ceng)(ceng)(ceng)的(de)厚薄、表皮(pi)透(tou)明層(ceng)(ceng)(ceng)(ceng)及顆粒層(ceng)(ceng)(ceng)(ceng)的(de)厚薄影(ying)響。若角(jiao)(jiao)質層(ceng)(ceng)(ceng)(ceng)較厚,則皮(pi)膚偏黃色;顆粒層(ceng)(ceng)(ceng)(ceng)和透(tou)明層(ceng)(ceng)(ceng)(ceng)厚,皮(pi)膚則顯白(bai)色。
據目前臨床研(yan)究發現,日(ri)曬(shai)、日(ri)光(guang)是對黑素(su)代(dai)謝(xie)影響最大的外(wai)部因素(su),紫外(wai)線可使表皮內的黑素(su)小(xiao)體(ti)迅速(su)重新分布,將黑素(su)集中到(dao)日(ri)曬(shai)部位。
研究發現,神經因素同(tong)樣會影響黑素代謝,長期處于精神緊張、疲勞(lao)甚至是失眠的(de)狀況,將影響人體的(de)神經功能(neng)及腎上(shang)腺皮脂功能(neng),激發斑(ban)的(de)形成。
