油不等于屏障健康。很多油性皮肤同时存在屏障受损，表现为外油内干、使用产品刺痛。

SBT 的建议是温和减法：少酒精、少强表活，不要用高频去角质来「控油」，那会让墙更漏。

产品次序上，油性皮肤以修护水为主角，修护乳按需少量，霜可只在干燥部位局部使用。

Oily does not mean healthy. Many oily skins are also barrier-damaged, presenting as oily surface with a dry, stinging interior.

SBT recommends gentle subtraction — no alcohol, no harsh surfactants, no frequent exfoliation to 'control oil', which only worsens the leak.
