医疗建议需要更高等级的证据：随机、对照、足够样本、可重复、经同行评议。

对于湿疹、玫瑰痤疮、银屑病、重度痤疮等，应以皮肤科医生的诊断与处方为准，护肤只承担日常温和护理的角色。

出现持续红斑、渗出、剧烈瘙痒或皮损扩散时，请停止自行处理并就医。

Medical advice requires higher-grade evidence: randomised, controlled, adequately powered, reproducible and peer-reviewed.

For persistent redness, oozing, severe itch or spreading lesions, stop self-treatment and seek medical care.
