Does a YSL fragrance refill share the bottle batch code?
Do not assume so. The refill is produced and filled separately; record the mark on the refill supplying the current fragrance as well as the reusable bottle.
Check Yves Saint Laurent Cosmetic Batch Code
Yves Saint Laurent Beauty covers Libre, Black Opium, Mon Paris, Y, MYSLF, L’Homme and La Nuit de L’Homme fragrances alongside Touche Éclat complexion products, Lash Clash mascara, Rouge Pur Couture and Loveshine lip color, and skincare. The fashion house also sells bags, shoes and accessories; their serial or style references are outside a cosmetic batch-code check.
Which code to enter on Yves Saint Laurent packaging
On YSL products, look beyond the bottle and box: refill bottles, jar and pump bases, tube crimps, compact backs and lipstick bottoms. A refill is filled separately, so use the code on the refill itself.
On Yves Saint Laurent packaging, the batch code is the number tied to when the product was made. If the pack also prints a manufacture date (MFG or PROD), that date is more direct.
- Batch code: enter this one
Printed, stamped or laser-etched apart from the barcode: on the box flap, the base of a bottle or compact, or the crimped end of a tube.
- Barcode: not the batch code
The long number under the bars. It identifies the product and size, so every unit of it shares the same number.
- Product numbers: not the batch code
Reference, shade, volume and concentration labels describe the item, not when it was made.
On boxed fragrance, the codes on the box and the bottle usually match. If they don’t, ask the seller why.

Yves Saint Laurent: if the code can’t be dated
- Re-type the code exactly as printed. The letters O and I are easy to mix up with the digits 0 and 1.
- On boxed fragrance, try the code on the bottle as well as the one on the box. If they differ, the box may belong to another bottle.
- Look for a printed expiry date or the open-jar symbol, such as 12M or 36M, which counts from opening.
- Ask Yves Saint Laurent customer care. Send a clear photo of the code and say where you bought the product.
- Stop using it if the smell, color or texture has changed. A fragrance that smells sharp or sour has turned.

Yves Saint Laurent FAQ
Is a YSL lipstick shade number the batch code?
No. Shade and finish identify the retail color. Look for a separate compact production mark on the lipstick, label, refill, or carton.
Can I enter a YSL handbag serial number here?
No. Fashion goods use different identification systems. Only YSL Beauty fragrance, makeup, and skincare package markings are relevant to this check.
How old Yves Saint Laurent products are when checked
Yves Saint Laurent products checked on Lot Date were typically dated to about 22 months before the check.

25%dated more than three years before the check
Estimated from Lot Date readings for Yves Saint Laurent between Jun 12, 2026 and Oct 9, 2026. Each code counts once per visitor, and readings that can’t be right, such as barcodes or dates after the check, are left out. The figures describe the products people chose to check, not everything Yves Saint Laurent sells, and differences between brands partly reflect how precisely each brand’s codes can be dated.
YSL Beauty fragrance, makeup, skincare, and refill lot check
Before you rely on the decoded date
- Inspect fragrance bottle and carton bases, refill bottles, jar and pump undersides, tube crimps, compact backs, mascara barrels, and lipstick or gloss bottoms for a compact production mark. Scent concentration, shade number, SPF, milliliters, product reference, barcode, and fashion-item serial are not the beauty formula’s batch code.
- Libre Eau de Parfum refill bottles are intended only for Libre bottles marked refillable, including specified 10, 30, 50 and 90 ml formats; Y and selected Black Opium presentations also have refillable versions. A later refill is its own filled product and may not share the reusable bottle’s lot. A Libre body balm, hair mist, gift-set mascara, and eau de parfum likewise require separate checks despite sharing collection artwork.

Common lookup mistakes
- Photograph the YSL bottle, refill, and carton markings before refilling or recycling them, and retain the exact scent, concentration, shade, and size with the suspected lot.
- Store fragrance upright away from heat and light, keep makeup and skincare applicators clean, and replace a formula after leakage, persistent odor or color change, separation, drying, dispensing trouble, or an unexpected eye or skin response.
