Your Guide to Navigating the Secondhand Beauty World

If you’re curious about shopping secondhand beauty — or you’ve already fallen down the rabbit hole (welcome, we see you!) — you’re in the right place. Whether you're here to save money, reduce waste, or just rehome a few barely-used favorites, we’ve got your back. Here's what every beauty lover should know before diving into the secondhand beauty world.

💧 Skip the Liquids (sorry, lip gloss lovers)

We get it — it’s tempting to snag that viral creamy concealer or half-used lip gloss for a steal. But here’s the thing: anything liquid or cream-based (think foundation, cream shadow, lipstick) is way harder to sanitize. These types of products are more prone to bacteria and fungi because of their high water content. If it’s not brand new and sealed, it’s better to pass.

✏️ Powders and Pencils Are Your Besties

If you’re going secondhand, powders are your safest bet. Blush, bronzer, eyeshadow — you can easily scrape off the top layer and give it a quick spritz of 70% isopropyl alcohol to clean it up. Pencil products like eyeliners or lip liners? Even better. Just sharpen them and wipe with a little alcohol, and you’re good to go. Easy, safe, and totally worth it.

🌿 A Heads-Up on Clean Beauty

Natural and clean beauty products are amazing — but they also come with a shorter shelf life. Since they’re usually made without preservatives, or less efficacious ones, they can go bad a lot faster than conventional ones. If a product smells weird, the texture has changed, or it just seems off, trust your instincts and let it go. When buying secondhand clean beauty, check that it’s still in great shape before diving in.

🔍 Double-Check the Packaging

If a product’s packaging looks slightly off — like the font is weird, the logo looks sketchy, or something feels "off" — it might be a dupe or counterfeit. Be extra cautious here. Buying secondhand doesn’t mean compromising on quality or authenticity. Stick with trusted platforms with solid buyer protection policies, and products are you already familiar with (so you can tell what a normal product looks, feels, and smelsl like).
