Maintenance and Storage
- Store the serum in a cool, dry place, away from direct sunlight.
- Ensure the cap is tightly closed after each use to prevent oxidation and maintain product efficacy.
- Avoid extreme temperatures.
Troubleshooting and Common Questions
- Skin Irritation: If you experience redness, itching, or irritation, discontinue use. Consult a dermatologist if symptoms persist. Perform a patch test on a small area of skin before full application, especially if you have sensitive skin.
- Serum Color Change: Vitamin C serums can naturally oxidize over time, leading to a darker color. While minor discoloration is normal, significant darkening may indicate reduced efficacy. Ensure the cap is sealed tightly after each use and store in a cool, dark place.
- No Visible Results: Consistent use is key. Skin improvement can take several weeks. Refer to the "Comparison before and after use" section for expected timelines.
