When It's Time to Toss: A Complete Guide to Makeup Expiry

It is common for anyone with a makeup bag to have it slowly fill up with new products as we jump on board beauty trends to try, pushing old products to the bottom of the bag until we remember and reach for them again. But cosmetic products have a shelf life which a lot of people tend to forget. 

Although some products are known for their long life, others, such as foundation, lipstick, and skincare, like cleansers and retinol products, have limited longevity. To maintain healthy skin, you have to be prepared to let go of cosmetics when they expire. In this article, we’ll break down everything you need to know about cosmetic expiry dates, from what can occur if you use expired items to the time cosmetics typically last.

Understanding The Expiration Date

The manufacturing date and period after which any given cosmetic product is good for a specific time can be successfully found with the help of the Period After Opening symbol (PAO) on the product's packaging. This symbol shows a jar with no cover that is often printed with a number next to the letter "M." For example, 12M means use the product within 12 months of opening.

The Lifespan of Some Common Cosmetics and Skincare Products

Different products will naturally have either shorter or longer lifespans. Generally, products that contain water (like liquid foundations and skincare items) expire more quickly because they can harbour bacteria. In contrast, products with a powder base (like eyeshadows and blushes) tend to last longer.

Identifying Expired Products

Identifying expired products involves paying close attention to changes in appearance, texture, smell, and performance. Below are some detailed signs to watch out for.

Smell

A change in smell is often the first sign of expiration. Foundation may develop a sour or chemical odour, while mascara can smell like gasoline or chemicals. Lipsticks might emit a waxy or rancid scent. Moisturisers and creams may take on a sour or musty smell, and expired sunscreen or retinol products often have unusual or strong odours.

Texture

Expired products frequently change in texture. The foundation may thicken, thin, or separate into layers. Mascara can dry out, and clump, and lipstick may become too dry or overly soft. Eyeshadows might develop a chalky texture, and moisturizers or creams may separate or become grainy. Sunscreen can become watery, while retinol products may turn gritty.

Colour Change

Colour changes also indicate expiration. Your foundation might darken or turn orange, and lipstick may lose its vibrancy. Eyeshadows can fade or develop mould, while retinol products often shift from pale yellow to deeper orange or brown.

Impacts of Expired Products on Your Skins 

• Infections: Bacteria can grow in old makeup, leading to skin infections.
• Irritation: Expired products can cause redness, itchiness, and other allergic reactions.
• Reduced Efficiency: Over time, active ingredients in skincare products can degrade, making them less effective.

Other Factors That Impact the Expiry Date

Beyond cosmetic products' natural shelf life, several external factors can impact their expiration date, leading to faster degradation or reduced effectiveness.

High Temperature

Storing cosmetic products in environments with higher room temperatures can cause the products to break faster than they typically would if stored under the correct temperature. This can lead to your foundation and lipstick melting or dissolving to alternate their consistency and be less effective. Products stored in warmer rooms of your home are exposed to this kind of situation.

Humidity

Overmoisture can induce the growth of bacteria and harmful fungi, which is especially the case with products such as powders, eyeshadows, and creams. This can shorten the product's lifespan and can also make it potentially unsafe to use.

Light Exposure

Products tend to lose their effectiveness when they absorb light, especially sunlight. Retinol and Vitamin C serums are the most sensitive to light; therefore, their productivity will decrease over time. Keep the products in a cold, light-free space to ensure they remain as they should be.

Air Exposure

The main way air affects products is by altering their original colour, texture, and smell. This usually happens when you have a jar or a pot you need to dip your fingers into, like creams and balms. It is recommended that you always seal these kinds of products when not in use to extend their usefulness.

Tips and Tricks to Keep Track of Expiration Dates

• Label Products: Use a fine-tipped marker to note the opening date on each product.
• Store Properly: To extend their lifespan, store products in a cool, dry place away from direct sunlight.
• Regular Cleaning: Clean applicators and brushes regularly to prevent contamination.
• Declutter Regularly: Go through your makeup bag every few months and discard any expired products.

Creating and maintaining a fresh and safe collection of makeup and skincare requires you to regularly check product expiring dates and how long you’ve had certain products in your cosmetic case. Following these primary rules means the products you apply to your skin are not only effective but also safe for your health. In case you are not sure, it is better to throw away an old product that may cause skin reactions.
