5. Certain makeup products have been open for +6 months
Besides eye makeup, you should also throw out other beauty products as soon as they reach 6 months since they were first opened. The most important makeup products you need to watch out for when it comes to this 6-month rule include eyeshadow compacts, bronzer and blush compacts, and powder foundation compacts. These products are predisposed to bacteria from direct contact with fingers and/or makeup brushes, which need to be washed regularly.
4. The texture of your makeup is starting to degrade or clump
When makeup products are exposed to air and/or high temperatures, their formulas can be easily altered, and the proof of this is when they start to look degraded, dried up, or clumped. These changes indicate that the product’s formula has oxidized and is likely to cause skin irritation or other issues. More importantly, remember that even though it seems genius, it’s actually a bad idea to dilute clumpy mascara with eye drops or water. This will only end up weakening the formula and ruining the pigment.
3. Your makeup has been used by someone else
Sharing makeup with someone else is a very bad idea because your makeup can become contaminated the second it comes into contact with bacteria from another person’s body. This isn’t good for both sides. Your body may react badly to foreign bacteria, making you at risk for infection (same goes for your friend). This is especially true for eye makeup products. So try to never let anyone use your makeup, and if they do, just throw it out or let them have it.
2. Oils and pigment have started to separate
As soon as you start noticing that oils and pigment in your cream or liquid formula are separating, you should kiss your makeup goodbye. High temperatures and oxidation mainly cause this separation, and it indicates that the formula went through a chemical alteration and is no longer good for your skin. If you still choose to apply a product after it is degraded chemically, you’d put skin at risk of irritation or worse.
