Storage Guide for Maintaining Optimal Efficacy of Cosmetics

1. The Importance of Blocking the External Environment
Chemical Sensitivity: Cosmetics are mixtures sensitive to temperature and light, and ingredients may deteriorate depending on the environment.

Antioxidant: In particular, functional ingredients such as Vitamin C and retinol oxidize when exposed to air, heat, or light, causing a rapid decline in efficacy.

Storage Principle: The basic rule is to store in a cool, well-ventilated place away from sunlight.

2. Precautions for Refrigeration
Temperature change warning: Temperature changes caused by frequent opening and closing of the door of a standard refrigerator can cause separation of components (layer separation).

Suggested Alternative: * Recommended use of a dedicated cosmetic refrigerator that maintains a constant temperature.

If that is not feasible, a shaded dressing table away from direct sunlight is safer.
