A new SKU should make the range easier to understand. If it repeats the hero product in a different jar, it may add operational cost without adding customer value.
Ask what new job it earns
Name the customer, moment and outcome the new product owns. A richer moisturiser may make sense if the current hero cannot serve night use or severe dryness without losing its daytime feel. A second serum that promises the same brightness story probably needs a sharper reason.
Draw the routine before writing the formula
Where does the product sit? What comes before and after it? Does it replace something or add a step? If the founder cannot explain the routine in one breath, the customer will struggle too.
Keep a shared thread without cloning
A range can share a botanical story, treatment philosophy or sensory signature. The exact ingredient system does not need to be copied into every SKU. Give each format the material form, use level and supporting ingredients appropriate to its job.
Check the unromantic math
- Development, testing and packaging cost
- Minimum batches and raw-material MOQs
- Inventory overlap and shelf life
- Expected order value and repeat behaviour
- Whether the new product strengthens or distracts from the hero
Use a simple go or not-yet test
Move forward when the new SKU solves a distinct problem, fits a clear routine, supports the brand story, can meet cost and production realities and does not weaken the claims or attention of the current line. “Customers keep asking for it” is useful evidence. “Competitors have one” is not enough.
