DDF FAQ
Is SPF 15 or a DDF product name the lot code?
No. SPF, product names, treatment claims and barcodes identify the product or its use. A lot is a separate production mark on the package.
Can a DDF date estimate confirm an old product is safe?
No. Use the estimate with the label's expiry or PAO and inspect storage, seal, smell, texture, colour and packaging. Stop if the product has changed or the label is unclear.
How to review a DDF Doctor's Dermatologic Formula lot
Before you rely on the decoded date
- A DDF Daily Protective Moisturizer UV Moisturizer SPF 15 is identified in Canada's public DDF product range as a specific product with active sunscreen ingredients. That product name, SPF number, DIN or barcode identifies the item or regulation record, not the manufacturing lot.
- DDF treatment language such as acne, anti-ageing, sensitive skin, cleanser, moisturizer or therapeutic mask describes the product purpose. Keep it separate from a short production mark and from the open-jar PAO or printed expiry information.
Common lookup mistakes
- Because DDF products may be older stock, transcribe every short mark from the container and carton and record the exact product name and SPF. The available brand and DDF product range do not establish one fixed code position for every DDF pack.
- Do not treat an estimated production period as a safety verdict. Check the printed label, PAO or expiry, seal, storage, smell, texture, colour and container condition before using a legacy DDF product.
