When it comes to skincare, keeping track of expiration dates is crucial. You might be holding onto a collection of skincare products that have been sitting in your drawer for quite some time.
The question is, do skincare products expire, and how can you determine if they are still safe to use? Let’s delve into the world of skincare product expiration and find out the signs you should watch out for.
Understanding Skincare Product Expiration
Skincare products, including moisturisers and serums, can degrade over time. Although you might not find an explicit expiration date on non-drug products, like acne treatments or sunscreen, there are still ways to gauge their safety.
Dr. Bruce Brod, a dermatologist at Penn Medicine, points out that some products might display a “period after opening” symbol with a time frame for safe use. However, this labelling is not mandatory, and even if present, it’s only useful if you remember when you first opened the product.
The Risks of Using Expired Skincare Products

Dr. Brod emphasizes that if you can’t remember when you purchased a skincare product, it’s better to err on the side of caution and avoid using it. Using products that are past their prime can lead to potential risks.
Over time, opened skincare products can degrade and become breeding grounds for microorganisms. Elisabeth Anderson, from the Center for Research on Ingredient Safety at Michigan State University, warns that products exposed to moisture, like those in bathrooms, can easily become contaminated.
Contaminated products can lead to skin irritation, eczema, and infections. Dr. Anne Chapas, a dermatologist from the American Academy of Dermatology, notes that applying a contaminated product directly to your skin can result in serious facial infections, especially if there are scratches or abrasions.
The Impact of Time on Skincare Products

Preservatives in skincare products help prevent infections, but they can break down over time, particularly when stored in humid environments or exposed to sunlight. Active ingredients, like Vitamin C and hyaluronic acid, can also degrade when exposed to air and light, making the product less effective. Dr. Chapas advises against using these products beyond a year.
Skincare products containing sunscreen or acne treatments should never be used beyond their printed expiration dates. Additionally, products with essential oils like tea tree oil can become harmful if exposed to light and air for too long.
Determining Safety and Effectiveness

The most accurate way to determine if an older skincare product is safe is to have it lab-tested for bacteria. However, there are some telltale signs of degradation you can watch for. Separation of oil and water, changes in texture or color, and a bad or unusual smell are indications that a product has degraded. If something seems off, it’s best not to use it.
Making Informed Decisions
To keep track of product lifespans, mark the opening date of a new serum or moisturiser and check for any expiration dates or PAO symbols on the packaging.

Generally, most skincare products are safe for six months to a year, with exceptions for eye products that might have a slightly shorter shelf life. When in doubt, it’s better to dispose of a product than risk potential harm. Remember, your skin’s health and safety come first.
In conclusion, skincare product expiration is a real concern. Without explicit expiration dates, it’s crucial to watch for signs of degradation and contamination. Keeping your skincare routine fresh and safe ensures that you’re getting the most out of your products while prioritizing your skin’s well-being.
