How do you set shelf life and PAO for skincare sold in the UK?

Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

• To set shelf life and PAO for skincare in the UK, we follow stability testing protocols per UK Cosmetic Regulations, which mirror EU standards.
• We conduct accelerated tests over 3-6 months and real-time tests for 12-24 months to validate product integrity and determine accurate labeling.
• This includes microbial, pH, and viscosity checks under controlled temperature and humidity conditions, crucial for claims like 24-month shelf life or 6M PAO.
• Testing is done in accredited labs, and we compile data for Product Information Files (PIF) and Cosmetic Product Safety Reports (CPSR).
• MOQ guidance: typical skincare MOQs start at 5,000 units per SKU to amortize testing costs, but we can adjust for smaller runs with higher per-unit fees.
• Sampling timeline involves lab dips and pilot batches, taking 4-6 weeks, including stability test initiation.
• Packaging must be airtight; we use barrier materials like PET jars and conduct compatibility tests to prevent leakage or degradation.
• Lead time from approval to production is 10-14 weeks, factoring in testing, packaging sourcing, and QA audits.
• We support documentation and testing logistics, but regulatory approval remains the brand owner’s responsibility, as market specifics vary.
