How to avoid allergic reactions caused by using cosmetic-grade pearlescent pigments?
Cosmetic-grade pearlescent pigments are widely used in various cosmetics, such as eye shadow, lipstick and foundation, to enhance their gloss and color effects. However, these pigments may sometimes trigger allergic skin reactions. To avoid this, you can take the following measures:
It is important to understand the possible allergens in cosmetics. Cosmetic-grade pearlescent pigments are usually made of materials such as mica and iron oxide, but some of the additives such as pigments, preservatives and fragrances can become major allergens. By carefully reading the product ingredient list, you can identify potential allergens.
Choose products marked with no added preservatives, no fragrances, and no pigments. Many brands have launched cosmetics for sensitive skin, which are more gentle and less irritating to the skin. These products usually state "hypoallergenic" or "sensitive skin" on the packaging.
Before using new cosmetics, it is recommended to perform a skin test. Apply a small amount of the product to a more sensitive area of ​​the skin, such as the inside of the wrist or behind the ear, and observe for 24 hours. If there are no allergic symptoms such as redness, swelling, and itching, use it fully. This method can help detect and avoid allergic reactions early.
If you have a history of allergies or sensitive skin, it is recommended to consult a dermatologist before using new cosmetics. The doctor can recommend suitable product types and ingredients based on your individual skin condition and allergy history. In addition, professional allergy tests can be performed to identify specific allergens for better avoidance.
Expired or improperly stored cosmetics may change in composition, leading to allergic reactions. Make sure the products used are within the shelf life and are stored correctly according to the product instructions, such as avoiding direct sunlight, high temperatures or humid environments.
Frequent changes in cosmetic brands or types will increase the skin's inadaptability to new ingredients, which in turn can cause allergic reactions. It is recommended to choose brands and products that are suitable for your skin and use them for a long time to reduce the pressure of skin adaptation.

What are the consequences of improper storage of cosmetic-grade pearlescent pigments?
If cosmetic-grade pearlescent pigments are not stored properly, they may cause a series of problems that affect their effectiveness and safety. Here are some common consequences of improper storage:
Some ingredients in pearlescent pigments, especially natural minerals or synthetic materials, may undergo chemical changes under inappropriate storage conditions. For example, when exposed to high temperature or humidity, the pigment may oxidize, discolor or decompose. This not only affects the gloss and color of the pigment, but may also produce byproducts that are harmful to the skin.
Improper storage, especially in humid or hot environments, can easily lead to microbial growth. Microbial contamination such as bacteria and mold not only changes the texture and smell of cosmetics, but may also cause skin infections or allergic reactions. Products that are not well sealed are more susceptible to microbial invasion.
Pearlescent pigments are usually in the form of powder or paste. If stored in an environment with excessive humidity, powdered pigments may clump and paste pigments may become thinner or stratified. These changes will affect the effectiveness of cosmetics and make them difficult to apply evenly or mix with other cosmetics.
Even if the pigment does not undergo obvious physical or chemical changes, improper storage may reduce its effectiveness. For example, the pearlescent effect is weakened and the color saturation is reduced. This will directly affect the decorative effect of cosmetics, making it unable to achieve the expected makeup effect.
Deterioration of ingredients or microbial contamination caused by improper storage may cause skin problems such as allergies, irritation, redness, itching, etc. Using spoiled cosmetics not only affects the appearance, but also damages the health of the skin.
Cosmetic-grade pearlescent pigments can maintain stability for a long time when stored under appropriate conditions. However, improper storage conditions will greatly shorten its shelf life, making it lose its use value before reaching the marked expiration date. This not only causes waste, but also increases the economic burden on consumers.
