The question of whether all cosmetic products need extra testing for UK compliance, or whether all cosmetic products need microbiological, stability, or challenge testing, often comes up. What extra testing is needed?
Some cosmetic products do require additional compliance checks or laboratory tests before a CPSR can be issued and before you’re legally allowed to sell them in the UK. The exact requirements depend on your formulation, the type of product you’re making, and whether it needs specific testing such as microbiological testing, stability testing, challenge testing, or purity checks for certain raw materials.
If you’re unsure which cosmetic tests apply to your product, I’ll guide you through everything step‑by‑step. I’ll review your formulation, explain which checks are required, and—if testing is needed—refer you only to trusted UK laboratories and testing companies that I personally know and recommend.
