Not to worry, this is normal. You may notice that your serum goes from pale yellow to deeper orange or that overtime, there are shifts in smell common for high concentrations of Vitamin C. We’ve intentionally packed our Sunrise Glow Serum with 15% Vitamin C, a safe but infrequent level of this potent and wildly effective ingredient. To avoid such shifts, we suggest storing our Sunrise Glow Serum in a refrigerator or other dry, cool, dark place. Please also note that our ingredients perform best when used fresh. Don’t be afraid to use our products generously and on the face, neck and body, wherever your skin would love a little extra TLC! For any concerns or questions, never hesitate to reach out to us via email! We’re here to help.
