Where should I look for the Collagena lot?
Check the bottle base or tube crimp on the Collagena cleanser, then compare the jar base, tube end or bottle base when the item is moisturizer. Keep the outer box until both have been checked.
Collagena treatment products appear in tubes, jars and serum bottles, making the container type more useful than one fixed code location. Compare the primary pack with its carton before deciding whether a short line is a lot, expiry field or retail reference.
Check the bottle base or tube crimp on the Collagena cleanser, then compare the jar base, tube end or bottle base when the item is moisturizer. Keep the outer box until both have been checked.
Collagena size and product references describe the serum or cream, and the PAO symbol describes use after opening. The lot should be a separate variable string on the base, crimp, or matching carton.
A Collagena date estimate cannot verify authenticity or account for the way a serum or moisturizer was kept after manufacture. Examine the dispenser, odor and consistency separately.
For Collagena, combine the decoded date with product type, PAO, storage, and seller context before deciding whether to open, keep, replace, or buy.
