“酒精”是一大類具有不同性質(zhì)的化學(xué)品的統(tǒng)稱。一般被用于消毒的，是一種叫異丙醇的酒精，它確實(shí)會(huì)導(dǎo)致肌膚干燥。但是這種酒精很少會(huì)被化妝品所使用?；瘖y品中所用的酒精都是經(jīng)過特殊處理的**酒精。這類酒精能快速從皮膚表面揮發(fā)，讓皮膚感覺清涼爽快，但不會(huì)引起干燥或敏感。<br/> 3.任何肌膚均可使用酒精<br/> 酒精無害，并不意味著含酒精的化妝品適用于所有人群。對(duì)此，河北硫酸銅粉末，李利教授解釋，酒精在不同產(chǎn)品中的濃度有很大的差別，人們應(yīng)該根據(jù)自己皮膚的特點(diǎn)，挑選**適合自己的護(hù)膚品，河北硫酸銅粉末。一般不建議干性皮膚用含有酒精的制劑，對(duì)酒精過敏的人也不可使用。但是油性皮膚或伴有粉刺***的人可以選擇含酒精的護(hù)膚品。當(dāng)然，河北硫酸銅粉末，對(duì)于那些需要長期使用酒精制劑的人而言，比較好配合使用具有保濕潤膚的制劑，以保障皮膚表面各種成分的平衡。<br/>
