Summer is the time when we reach for SPF creams, lighter makeup, and hydrating mists more often. But it is during this period that cosmetics are most at risk – high temperatures, direct sunlight, and frequent travel can negatively affect their composition, effectiveness, and safety. How to prevent this?

1. High temperatures destroy active ingredients

Cosmetic products often contain active ingredients like vitamin C, retinol, hyaluronic acid, or natural oils. These substances are very sensitive to heat and light. If you store the cream in a hot car or leave your makeup in the sun, the effectiveness of these ingredients can rapidly decrease – or be destroyed completely.

2. Change in consistency and smell? Warning sign!

Heat can change the texture of a product – cream separates, oil thickens, lipstick spreads. Not only are such products harder to work with, but their composition can also change, increasing the risk of skin irritation.

3. Bacteria love warmth and moisture

Natural and organic cosmetics without preservatives are especially prone to spoilage. If you store the product in the bathroom or in a warm environment, bacteria and mold can start to multiply much faster - and this is not only unhygienic, but also dangerous.

How to store cosmetics correctly?

• Ideal temperature: 15–25 °C

• Avoid direct sunlight – never leave cosmetics on a windowsill or in a car

• Close the products carefully - this will prevent moisture and air from entering

• Use protective packaging – like the WELLBag cosmetic bag from Sister's Aroma
