Introduction: What is the Shelf Life of Natural Ingredient-Based Serums?
Natural ingredient-based serums like Millionaire Glow by Dr. Crazy Beauty contain active botanicals and vitamins that can degrade over time. Understanding shelf life helps you get the most effective results from your skincare investment. For acne-prone skin, always choose non-comedogenic, dermatologist-tested formulas that won't clog pores.
Typical Shelf Life of Key Ingredients
Vitamin C: highly unstable, degrades when exposed to light and air. Typically 3-6 months after opening. Niacinamide: relatively stable, effective for 12-24 months. Hyaluronic Acid: stable ingredient, effective for 12-24 months. Tranexamic Acid: stable and effective for 12-24 months. Natural Botanicals (Turmeric, Aloe Vera): 6-12 months after opening.
Signs Your Serum Has Expired
Color Change: Vitamin C serums turn yellow/orange when oxidized. Changed Smell: rancid or unusual odor indicates degradation. Texture Change: separation, cloudiness, or unusual consistency. Reduced Effectiveness: less visible results despite consistent use.
How to Extend Shelf Life
Store in a cool, dark place away from direct sunlight. Keep refrigerated if possible — especially for Vitamin C serums. Always close the cap tightly after use. Use a clean dropper or spatula to avoid contamination. Purchase in smaller quantities if using infrequently.
