Understanding Beauty of Joseon Batch Codes

There is a reason Beauty of Joseon codes are worth decoding. Prestige formulas — K-Beauty / Skincare included — degrade in ways that are invisible until the texture, scent or colour changes. The batch code is the only way to check before that happens.

Two codes on the same product are not a problem. The outer carton and the inner container are frequently produced in different runs, and the later of the two is the one that governs the freshness of what is inside.

If the packaging also carries a printed expiry date, trust the packaging. The batch code tells you when the product was made; the printed date tells you when it should be used up.

Beauty of Joseon Batch Code FAQ

How do I read a Beauty of Joseon batch code?
A Beauty of Joseon batch code is the short string printed on the product or its box. Enter it in the field above and the decoder returns the estimated manufacturing date, the expiry date based on the official shelf life, and whether the product is still within date.
What format does a Beauty of Joseon batch code use?
The decoder handles the documented Beauty of Joseon format: Letter-coded year followed by a numeric or letter month marker. Codes that do not match are rejected rather than guessed.
