Makeup doesn’t last forever, but many people are surprised by just how long cosmetic products are actually safe to use. Using expired makeup can lead to skin irritation, breakouts, eye infections, and reduced product performance.
In this guide, we break down how long makeup really lasts, how to spot when it’s expired, and how to store products correctly to extend their lifespan, without unnecessary waste.
What Does “Expired Makeup” Really Mean?
Unlike food, makeup doesn’t usually come with a clear “use by” date. Instead, most cosmetic products have a PAO (Period After Opening) symbol, a small jar icon with a number (e.g. 6M, 12M, 24M).
This indicates how many months the product is safe to use after opening.
However, expiration depends on:
- Ingredients and preservatives
- Whether it’s a liquid, cream, or powder
- How often it’s used
- Storage conditions
Once opened, exposure to air, bacteria, and moisture slowly breaks products down — even if they still look fine.
How Long Does Makeup Really Last? (By Product Type)
Below is a realistic breakdown of common makeup products and how long they typically last once opened.
Mascara and Liquid Eyeliner
Shelf life: 3–6 months
These are the highest risk products due to constant contact with the eyes.
Signs to throw away:
- Dry or clumpy texture
- Strong or sour smell
- Eye irritation or redness
Using expired mascara is a common cause of eye infections and styes.
Foundation and Concealer
Shelf life:
- Liquid or cream: 6–12 months
- Powder: up to 24 months
Watch for:
- Separation that doesn’t blend back
- Change in colour or smell
- Texture becoming thicker or patchy
Oil-free formulas tend to expire faster than silicone-based ones.
Lipstick and Lip Gloss
Shelf life:
- Lipstick: 12–18 months
- Lip gloss: 6–12 months
Lip products collect bacteria quickly due to repeated contact with the mouth.
Throw away if:
- Smell becomes waxy or rancid
- Texture dries out or becomes gritty
Eyeshadow, Blush, and Bronzer
Shelf life:
- Powder products: 18–24 months
- Cream products: 6–12 months
Powders last longer because they contain less moisture, but they still expire.
Tip: Regularly clean brushes to prevent bacteria transferring into powders.
What Happens If You Use Expired Makeup?
Using expired makeup isn’t always immediately obvious — but over time it can cause:
- Skin irritation and sensitivity
- Breakouts and clogged pores
- Eye infections
- Reduced colour payoff and blending
- Patchy or uneven application
For people with sensitive skin, expired makeup can trigger contact dermatitis or allergic reactions.
How to Tell If Makeup Has Expired (Even Without Dates)
Even if you’ve lost the packaging, there are clear warning signs.
Check for:
- Unusual smell (sour, metallic, or chemical)
- Changes in colour or texture
- Separation in liquids
- Burning or itching when applied
If something feels “off”, trust that instinct.
Does Expensive Makeup Last Longer?
Not necessarily.
Price doesn’t guarantee longevity. Shelf life depends on:
- Preservatives used
- Formula stability
- Packaging design
Luxury, clean beauty, and natural makeup often has shorter shelf lives due to fewer preservatives.
How to Make Your Makeup Last Longer (Safely)
You can extend the life of your makeup without risking your skin.
Best practices:
- Store products in a cool, dry place
- Avoid bathrooms with high humidity
- Keep lids tightly closed
- Use clean hands and brushes
- Never share eye or lip products
Small habits make a big difference.
Should You Throw Away Makeup After COVID or Illness?
Yes, especially eye and lip products.
If you’ve had:
- Eye infections
- Cold sores
- Flu or viral illness
Replace mascaras, eyeliners, lipsticks, and glosses to prevent reinfection.
Expired Makeup and Sustainability
Throwing makeup away can feel wasteful, but using expired products isn’t worth the risk.
Sustainable alternatives:
- Buy smaller sizes
- Avoid backups you won’t finish
- Keep a simple, well-used collection
- Track opening dates with labels
Responsible use reduces both waste and skin damage.
Final Thoughts on Expired Makeup
Expired makeup isn’t always obvious, but it can quietly affect your skin, eyes, and overall health. Understanding how long makeup really lasts helps you make informed decisions, protect your skin, and get better performance from your products.
When in doubt, it’s safer to replace than risk irritation or infection.
