Foundation 粉底

With the exception of powder formulas, all foundations are water-based, which means bacteria love them. Unopened, foundation can last for a couple of years, but once the seal is broken, Hammer says, it's best to replace it after 6 to 12 months. Keep foundations out of moist environments (such as your bathroom) and away from heat, as high temperatures encourage the growth of the bugs and can speed up the spoiling—true for beauty products in general. An off smell or a change in color tells you the formula is finished—applying it could cause irritation or breakouts。

Tips：粉底都含水，所以易滋生細菌。沒開封的粉底可保質幾年時間，一旦拆封，6到12個月就該換了。變味和變色是粉底變質的征兆。
