温馨提示 WARM PROMPT 根据国际相关法令规定，“保质期超过30个月的化妆品无需强制标明保质期。对于此类产品，应标明产品开封后可安全使用且不会对消费者造成任何伤害的使用期限”。保质期默认为开盖后12~24个月内使用，包装上一般有此类图标。如消费者对产品保质期过于在意，以批次查询方式主张产品过期的，请谨慎下单，给您造成不好的购物体验请见谅。 产品介绍 PRODUCT INTRODUCTION 温和乳酸去角质配方。本配方的酸碱度约为3.8。乳酸的酸性值为3.8，而制酸的最基本因素就是酸性值。酸性值显示了酸的有效性。当酸性值接近酸碱度时，盐和酸度达到理想的平衡状态，可使酸的效力最大化并降低刺激性。在这种情况下，更高的酸碱度只会增加盐的含量，但事情可能和您想的不一样，比起酸含量的增加，盐含量的增加会使整个配方更具刺激性。注：因乳酸具有立竿见影的效果，及可能产生的与酸有关的炎症和过敏现象，一般推荐间接的皮肤去角质形式代替如本品的直接形式。 ○　规格：30ml ○　品牌：The Ordinary 产品特点 PRODUCT FEATURES ○　乳酸是一种能够去除皮肤角质的果酸； ○　本配方含有10%此种乳酸，用于温和去角质，并辅以精炼塔斯马尼亚胡椒莓，以减少伴随去角质可能产生的肌肤炎症和过敏现象； ○　本配方包含已被深入研究的塔斯马尼亚胡椒衍生物，以帮助减少与酸使用相关所产生的刺激； ○　该衍生物来自植物，并且随季节的不同颜色各异，该颜色变化在配方中随时间的变化显而易见。 适用人群 SUITABLE FOR ○　禁忌：乳酸切忌用于敏感、脱皮或受损皮肤。 使用方法 HOW TO USE ○　每日使用一次，晚间使用效果更佳。可用其他护理产品稀释减弱本品功效直至肌肤产生耐受力。避免接触眼部。若持续对皮肤产生刺激，请停止使用并及时就医。（晒伤警告：本品含有果酸（AHA），可能增加皮肤对太阳光的敏感度，尤其可能导致晒伤。使用本品时及其后一个星期内，请使用防晒霜，穿戴防晒装，减少阳光直射。） 注意事项 ATTENTION ○　请严格按照说明使用； ○　避免触及眼睛，切勿食用； ○　请勿将其放置在儿童可触及的地方； ○　请存放于避光、干燥、不高于25摄氏度处； ○　如产品不慎入眼，请立即用大量清水冲洗干净； ○　若使用后发生红肿过敏现象，请立即停止使用。 The Ordinary Lactic Acid 10% + HA 2% - a high-strength lactic acid superficial peeling formulation. Lactic Acid is an alpha hydroxyl acid that exfoliates the skin. This 10% formulation offers mild exfoliation and is supported with a purified Tasmanian pepperberry known to reduce signs of inflammation and sensitivity that is often associated with exfoliation. This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time. This pH of this formula is approximately 3.8. Lactic Acid has a pKa of 3.8 and pKa is the most important aspect to consider in formulating with acids. pKa implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximising effectiveness of the acid and reducing irritation. Higher pH numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic. Alcohol-free, silicone-free, nut-free, vegan, cruelty-free. Note: While Lactic Acid can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation and sensitivity associated with acids. Directions: Apply once per day, ideally in the PM. Can be diluted with other treatments to reduce strength until skin develops tolerance. Lactic Acid should not be used on sensitive, peeling or compromised skin. Avoid contact with eyes. If irritation persists, discontinue use and consult a physician. Sunburn Alert: this product contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.
