沧州美容学校告诉你护肤品可以保持多久
日期:2018-09-19 16:01:44

你注意到你护肤品的失效日期了吗?我们平日保养所用到的精华,保湿剂,面膜,清洁剂,眼霜 - 所有这些护肤品都有失效日期,如果没有正确保存, 所有这些都可能变得无效,或者更糟 - 受到污染。 那么如何解读护肤品的保质期呢?沧州美容学校认为需要考虑以下的几点: 

到期日:如果产品中含有活性成分,则有效期限与活性成分有关,而不与产品的保质期或整体“新鲜度”有关。 “标签上的打印失效日期仅表明产品中'主动'的有效性。” “这可以是三到十二个月的任何时间。” 

保质期:护肤产品经过稳定性和微生物挑战测试,以确保配方保持稳定,并且在货架期内产品内不会产生任何不需要的东西, 大多数没有保质期的产品通常保质期为12至36个月。 

PAO:大多数护肤品在包装上都会有PAO(开封后的期限)符号。 这个标志的目的是让消费者知道打开产品后多久可以安全使用而不会造成伤害, PAO标志看起来像一个开放式的美容霜瓶,上面有一个数字,后面跟着字母'M',它是指'月'。 因此,例如,一个显示'24M'的PAO符号表明该产品在打开后可以安全使用24个月。

污染:当我们谈到护肤品时,最大的挑战之一就是不让它们污染。 “污染产品的水会在淋浴时很容易地进入瓶子和开口瓶。 “或者干脆将手指放进一罐保湿霜中,也会增加污染的可能性。”出于这个原因,建议使用防污染包装的化妆品,如管子,挤压瓶,喷雾剂,和个别胶囊。

我们可以通过一些技巧来确保您的护肤品持续的使用:把它们放在阴凉的地方(有些甚至可以放在冰箱里)不要把手指放在罐子里! 这可能会污染产品不要让水进入产品当中 - 保持干燥!避免阳光直射。

一般护肤品寿命时长列表:洗面奶:一般一年打开一次面部保湿霜:6至24个月。面部血清精华:6至12个月身体保湿霜:12至18个月防晒霜:6至12个月

Have you noticed the expiration date of your skin care product? The essence, moisturizer, mask, cleanser and eye cream used in our daily maintenance are all expiration dates. If they are not properly stored, all of them may become ineffective or worse. So how to interpret the shelf life of skin care products? Cangzhou cosmetology school considers that the following points need to be considered:
Maturity Date: If the product contains active ingredients, the validity period is related to the active ingredients, not to the product shelf life or overall "freshness" of the relevant. "The expiration date on the label only indicates the validity of the initiative in the product." "This can be anywhere from three to twelve months."
Shelf life: Skin care products are tested for stability and microbial challenge to ensure that the formulation remains stable and does not produce anything unnecessary during the shelf life of the product. Most products without shelf life usually have a shelf life of 12 to 36 months.
PAO: most skin care products will have PAO (time limit) after packaging. The aim of the logo is to let consumers know how long they can safely use the product without causing harm. The PAO logo looks like an open beauty cream bottle with a number on it followed by the letter'M', which means'month'. Therefore, for example, a PAO symbol showing'24M'indicates that the product can be safely used for 24 months after opening.
Pollution: when we talk about skin care products, one of the biggest challenges is not to let them pollute. "Water from contaminated products will easily enter bottles and openings in the shower. "Or simply putting your fingers in a can of moisturizing cream will also increase the possibility of contamination." For this reason, it is recommended to use contamination-proof packages of cosmetics, such as tubes, extrusion bottles, sprays, and individual capsules.
We can use a few tricks to make sure your skin care products are used consistently: Keep them in a cool place (some even in the refrigerator) and don't put your fingers in the jar! This may pollute the product and do not let the water enter the product - keep it dry! Avoid direct sunlight.
General skin care products life span list: facial cleanser: generally open once a year facial moisturizer: 6 to 24 months. Facial Serum essence: 6 to 12 months Body Moisturizing Cream: 12 to 18 months sunscreen: 6 to 12 months.
