Is the Potent-C percentage a batch number?

Peter Thomas Roth treatment lot and freshness check
Before you rely on the decoded date
- Inspect jar and bottle bases, tube crimps, pad or patch tubs, sachets, and cartons for the compact lot. Collection names, ingredient percentages, SPF values, and retail barcodes are not production identifiers.
- A jar mask or patch tub is repeatedly opened, while a serum dropper or pump has different exposure. Sunscreen follows its labeled expiration, and retinol or vitamin C condition also depends on light, heat, air, and visible change.
