上浓度太快才会出现这么严重的反应，开始用retinol 应该从 0.025%,开始。逐步过渡到 0.05% ，到 0.1%。从一周两次，到一周三次，到每日一次，皮肤需要适应过程，上浓度过快，会出现发痒，烧灼，水泡，发红，脱皮等，发炎后可能留下黑影，得不偿失。 Gels tend to be stronger than creams because they enhance penetration whereas the oils in cream bases act as slight buffers. Retinoids with an alcohol-based gel are stronger than water-based gels, which in turn are stronger than cream-based ones. Usually, gel-based retinoids are a preferred choice for those who have acne. Cream-based retinoids are best suited for more mature, oil-dry skin types, aiding in skin rejuvenation. Synthetic retinoids tend to be less irritating to the skin as they do not target all of the retinoic acid responders. For some people, natural retinoids may not be strong enough, even though they do target ALL retinoic acid responders.

非常感谢。。。。。。。。。。
抓住问下，我正在用retinol，从低浓度开始的，过了早期适应阶段以后效果非常好。 不知道怎么判断是否该过渡到下个浓度？我倒是不急，只是想知道是不是皮肤适应低浓度以后换到下个浓度档皮肤还要重新适应比如脱皮发红么？如果暂时停用retinol 一段时间，是要重新从低浓度开始适应重新来一遍脱皮发红么？想听听过来人的经验，谢谢啦
我目前用的是Skinceuticals retinol 0.3，打算用完这管再升级0.5.
不过我用tretinoin 0.025两三年了，还是不能每天用，只能隔天用(和vc交替晚上用)，更不要说增加浓度了。效果也是杠杠的，无斑无细纹零毛孔胶原蛋白还在
看你是买处方还是非处方吧？处方的Retin-A最低是0.025%， 最高是0.1%。非处方的没研究过，看牌子吧，不过应该浓度低于处方
