Can a Sunday Riley batch code show serum potency?
No. It cannot measure remaining active strength after the serum has been opened, heated, or exposed to air.
Check Sunday Riley Cosmetic Batch Code
Sunday Riley makes vitamin C, retinoid, acid, oil, and moisturizer formulas. A lot date establishes timing but cannot measure oxidation or remaining active performance.
Sunday Riley FAQ
How do face oils show age?
Rancid or paint-like odor, altered texture, and poor storage are more useful than color alone.
Can a recent lot make a heat-damaged product acceptable?
No. Storage damage can occur at any production age, so inspect odor, color, texture, and package integrity.
