澳大利亚健康专业人士和卫生监管机构发出消费者警示，提醒三类临床级护肤霜不应通过网络渠道购买。1这些产品包括维甲酸、氢醌和糖皮质激素，均属于处方药或高浓度治疗性商品，存在严重副作用风险。1
维甲酸作为处方药，会增加皮肤对日晒的敏感性，可能损伤皮肤屏障，且在孕期使用存在危害。1氢醌的风险同样不容忽视——浓度超过2%需凭处方购买，高浓度使用与罕见的永久性皮肤变色（外源性黑变病）相关联。1糖皮质激素常见于非法皮肤漂白霜中，大范围或长期使用会显著增加肾上腺功能不全等严重副作用的风险。1
从海外网站购买这些处方药面临多重法律和安全隐患。1消费者可能购得假冒产品，跨境包裹也可能被没收，甚至面临罚款或法律诉讼。1澳大利亚虽有合法的在线供应商提供此类产品，但必须先咨询注册医疗从业者并获得处方。1
Health professionals and Australian regulatory authorities have issued warnings against purchasing three categories of clinical-grade skincare creams through online retailers.1 These products—retinoids, hydroquinone, and corticosteroids—are either prescription medications or high-concentration formulations that carry significant health risks when used without proper medical supervision.1
Retinoids are prescription-only drugs that increase photosensitivity and can damage the skin barrier, with particular dangers during pregnancy.1 Hydroquinone formulations exceeding 2% concentration require a prescription and have been associated with exogenous ochronosis, a rare permanent skin discoloration, as well as ongoing debate regarding cancer risk.1 Corticosteroids may appear in illegal skin-bleaching creams, and their widespread or prolonged use can trigger serious adverse effects including adrenal insufficiency.1
Purchasing prescription medications from overseas websites exposes consumers to multiple legal and health hazards, including counterfeit products, border confiscation, fines, and potential litigation.1 While Australia does maintain legitimate online suppliers for these treatments, obtaining them requires prior consultation with a registered medical practitioner and a valid prescription.1
