Is the 3.8g Empty Silver White Button Round Lipstick Tube prone to wear or fading during long-term use?

The durability of the 3.8g Empty Silver White Button Round Lipstick Tube shell depends largely on its material and the surface treatment process used. If the lipstick tube shell is made of metal, such as zinc alloy, and is combined with advanced surface treatment processes such as oxidation and electroplating, it will usually have good wear resistance and fading resistance. Taking the oxidation process as an example, it can form a dense oxide film on the metal surface. This oxide film not only has a protective effect to prevent the metal from further corrosion, but also has a high hardness and can effectively resist friction in daily use, thereby reducing the risk of wear. The electroplating process can plate a layer of metal or alloy on the metal surface, making the surface of the lipstick tube smoother and brighter, and also enhancing its wear resistance and corrosion resistance. For example, using a multi-layer electroplating process, each layer plays a specific role, some are responsible for enhancing adhesion, some are responsible for improving gloss, and some are responsible for increasing wear resistance. Such a combination of processes can significantly improve the durability of the lipstick tube.

However, if the outer shell of the 3.8g Empty Silver White Button Round Lipstick Tube is made of plastic material, such as common ABS, PC, etc., and is only painted, long-term friction may cause the paint surface to wear or fade. Plastic material itself has a lower hardness than metal material and is more susceptible to external forces. Although painting can form a layer of color on the plastic surface, the adhesion between the paint surface and the plastic and the hardness of the paint surface itself are limited. In daily use, the lipstick tube will frequently contact the lips, hands and other items in the bag. These frictions may gradually destroy the integrity of the paint surface, causing scratches and peeling on the paint surface, thereby affecting the appearance of the lipstick tube.

Lipstick tubes will frequently contact the lips, hands and other items in the bag in daily use. When applying lipstick, the lips will exert a certain amount of pressure and friction on the top of the lipstick tube. The hands will also come into contact with the tube body when taking and placing the lipstick tube, and the keys, coins and other items in the bag may inadvertently collide and rub with the lipstick tube. These frequent frictions will gradually destroy the protective layer on the surface of the lipstick tube and accelerate its wear process.

High temperature, humidity or exposure to the sun may also cause the paint of the lipstick tube to fall off or the metal to oxidize. In a high temperature environment, the plastic material may soften, and the adhesion between the paint and the plastic may decrease, making the paint easier to peel off. A humid environment makes metal materials more susceptible to oxidation reactions, especially when the paint is damaged, moisture will penetrate into the metal surface, accelerating the corrosion and discoloration of the metal. Exposure to the sun will expose the paint surface to ultraviolet rays, causing the paint color to fade and turn yellow, affecting the appearance of the lipstick tube.

In the production process of lipstick tubes, a series of tests are usually carried out, such as wear resistance test and salt spray test. The wear resistance test can simulate the friction of the lipstick tube in daily use. By rubbing the surface of the lipstick tube for a certain period of time and observing its wear degree, its wear resistance can be evaluated. The salt spray test can simulate harsh environments such as humidity and salt spray to test the corrosion resistance and fading of the lipstick tube in such an environment. If the lipstick tube has undergone these rigorous tests, its durability is usually more guaranteed.

If the lipstick tube is frequently mentioned in user feedback as having wear or fading problems, it may indicate that the product has design or workmanship defects. For example, the surface treatment process is not in place, resulting in poor paint adhesion; or the material selection is unreasonable, which is easily affected by environmental factors and causes wear and fading.
