10 things you should never buy secondhand

Hygiene is a significant concern with used mattresses. You never know what kind of allergens, bedbugs, or bacteria might be lurking inside. A new mattress guarantees a clean and comfortable night’s sleep.
Underwear and Swimwear:
Items that come into direct contact with your skin should always be purchased new. Buying used undergarments or swimwear can pose hygiene and health risks.
Cosmetics and Skincare Products:
Cosmetics and skincare products can expire or become contaminated with use. Buying used makeup or skincare items can lead to skin issues or infections.
Child Safety Products:
Items like baby cribs, playpens, and high chairs should be bought new to ensure they meet current safety standards. Older models may have safety hazards that are not immediately apparent.
Toothbrushes:
Hygiene is paramount when it comes to oral health. Used toothbrushes can harbor bacteria and should always be replaced with new ones.
Bike Helmets:
Just like car seats, helmets for cycling or other sports should always be bought new to ensure they can provide proper protection in case of an accident.
Kitchen Appliances with Safety Features:
Appliances like toasters, kettles, and coffee makers that have safety features like automatic shutoffs should be bought new. Used appliances may lack these safety features or have them compromised.
Tires:
Your safety on the road depends on the condition of your tires. Buying used tires may save money upfront, but they can be worn out, damaged, or have hidden defects that can lead to accidents.
