Cosmetics, while often a cherished part of personal care routines, do not last indefinitely and using them beyond their intended shelf life can lead to adverse effects. Nujhat Khan, the director of Persona Beauty Care, shares insights into the longevity of various beauty products and tips on recognizing when they are no longer safe to use.
Recognizing Unsafe Cosmetics Changes in color, odor, or texture are primary indicators that cosmetics should no longer be used. If a product shows signs of mold, separation of ingredients, or unexpected textural changes even within its expiration period, it is advisable to discard it immediately. These changes can pose significant risks of bacterial infections, skin irritation, and other dermatological reactions.
Understanding Product Lifespan Most cosmetics come with an expiration date or a period-after-opening (PAO) symbol indicated by a number followed by ‘M’ (months). For example, if a product is marked with “12M”, it means it should ideally be used within 12 months of opening. While some items like nail polish might remain usable beyond their expiration under proper storage conditions, water-based products like certain foundations and mascaras have a shorter shelf life due to higher risks of contamination.
Storage Tips for Longevity Proper storage is crucial for maintaining the efficacy and safety of cosmetics. Products should be kept in cool, dry places away from direct sunlight. High moisture areas such as bathrooms, or high-temperature environments like a car, can accelerate the degradation of the products.
Expected Lifespan of Common Cosmetics:
- Lipsticks can be used safely for up to a year if they contain water, otherwise up to three years.
- Lip gloss generally lasts for about a year, but if water is present it may spoil sooner.
- Blush and bronzers, whether in liquid, powder, or cream form, are typically good for up to three years.
- Foundations can be safe to use for up to two years, but those in liquid form need to be shaken well before use to ensure they are still good.
- Eyeshadows are safe for one to three years, depending on whether they contain water.
- Eyeliners and mascaras should ideally be replaced every three to six months, especially liquid types which are prone to bacterial growth.
- Concealers last from six months to a year if liquid, and up to one and a half years if in cream or powder form.
- Highlighters follow similar guidelines to concealers, lasting from six months to two years.
- Nail polish is generally good for over three years.
- Perfumes can last between three to five years.
- Face creams should be used within three months to ensure their effectiveness.
Usage Guidelines It’s crucial to use cosmetics within these time frames and to ensure tools like brushes and applicators are kept clean to prevent skin problems and maintain product integrity. By following these guidelines, individuals can enjoy their beauty products safely and effectively, minimizing any health risks associated with outdated or deteriorated cosmetics.
