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.
- The most common reasons skincare products fail UK stability tests include **formulation incompatibility**, **packaging integrity issues**, and **non-compliance with testing standards**.
- Formulation failures often stem from ingredient interactions affecting pH or viscosity over time, while packaging leaks can occur due to poor seal designs or material reactions.
- Testing shortcomings may involve incorrect storage conditions or insufficient test duration, leading to unreliable shelf-life claims.
- To prevent failures, we conduct **feasibility studies during sampling**, which take 4-6 weeks and include small-batch stability checks under UK-simulated conditions. **MOQ guidance**: For effective testing, we recommend a minimum of 5,000 units per SKU to cover sample costs and repeated cycles. **Packaging validation** is critical; we test pumps and bottles for leakage risks under temperature swings, common in UK shipping.
- We assist by providing **detailed documentation**, such as stability reports and safety assessments aligned with UK regulations. **Lead time impact**: If tests fail, production can delay by 2-3 months for reformulation.
- Our R&D team offers reformulation support to ensure products meet claims without compromising quality, backed by audit-ready test records.
