My LaQ Lot Mark Guide

Before checking a My LaQ date, identify the exact product and package format. The variable line may sit at container base or rear panel; closure area and carton flap help recognise a shallow embossed line.

My LaQ FAQ

How do I keep the My LaQ shallow embossed line tied to the correct surface at container base or rear panel?

Start with container base, rear panel, closure area and carton flap. Keep shallow embossed line tied to the surface where it appears, and use side lighting as a second view when shallow embossing is difficult to see.

Which package numbers should not be joined to the My LaQ shallow embossed line on container base?

Read the My LaQ shallow embossed line independently of its barcode, size, shade or scent, distributor reference and PAO symbol. Compare shallow embossed line at container base with any variable print at carton flap; shade, scent and size references identify variants rather than production timing.

Can timing from the My LaQ shallow embossed line near container base or rear panel replace checks for odor, colour and seal?

For My LaQ, a shallow embossed line on container base or rear panel is only a timing clue. Record any second variable mark on closure area separately. Assess odor, colour, seal, dispensing and storage history directly.

Reading My LaQ date and lot-marking guide

Before you rely on the decoded date

  • Start at container base, then move through rear panel, closure area and carton flap. Copy shallow embossed line as one uninterrupted line, keeping its print style and exact surface noted while checking one package panel at a time.
  • Do not merge shallow embossed line with fixed retail copy such as the barcode, size, shade, scent, distributor number or PAO. Compare container base with carton flap while checking one package panel at a time before assigning a purpose to either line.

Common lookup mistakes

  • Record a wide My LaQ package view before the close-up of shallow embossed line. Add container base, rear panel and closure area in sequence and avoid mixing components from a set.
  • Check odor, colour, seal and dispensing directly after opening My LaQ, regardless of the package date. If container base and carton flap do not agree, retain both locations and consider transport and storage after the manufacturing stage; an estimated date does not override deterioration or uncertain storage.

What to check next for My LaQ

For My LaQ, combine the decoded date with product type, PAO, storage, and seller context before deciding whether to open, keep, replace, or buy.
