How long does it take to develop and manufacture a private label phytoestrogen skincare product?

For a white-label or lightly customized formula, lead time is typically 6–10 weeks including stability testing and label approval. A fully custom phytoestrogen formula can take 12–20 weeks depending on the number of formula iterations and accelerated stability study results.
