Product brief
Write a brief in everyday language: how the serum should look in the pack, how it should feel on the face, and how a first-time user should open and apply it. Note who it is for, when they would use it, and what “done” means for this launch. If you have a reference, say what to keep and what to change. If not, list open questions on texture, scent, and whether each unit is used once.
Formula and container compatibility
Routes a serum brief usually shortlists
Starting routes for a serum brief. None of these is promised as stock.
BFS single-dose
- One use, polymer unit
- Opening designed into the mold
Glass dropper
- Multi-use reservoir
- Familiar on a serum shelf
Glass ampoule
- Break-open neck
- Still a live filling route
Ask whether the formula and container are compatible over the intended product life. If the serum is water-based, oil-rich, or includes fragrance, the right pack may differ. If it is sensitive to light or air, ask whether the pack you are considering actually limits those exposures. Share formula type with whoever will fill it, and ask them to confirm the pack will not haze, leak, or change look or smell. If they cannot confirm that yet, treat compatibility as an open question.
Dose and opening
Decide what “one use” means: a thin layer over the face, a small targeted amount, or something a user might split. Then ask whether pack volume and opening method support the intended application. If the opening is too tight, product may stay behind; if it is wide or messy, the application may be difficult to control. If used while traveling, consider whether the unit should stay sealed until use. If leftover product would bother you or the user, say so early.
Samples and review
Do not approve a design from drawings alone if you can review filled samples. Ask for units that combine the real or closest formula with the actual pack, then open them the way a customer would. Check whether product comes out cleanly, whether the pack leaks after handling, and whether the serum still looks and smells as you intended. If several formats are on the table, compare them side by side and write down what failed and what felt right.
Retail presentation
Think about how a shopper first meets the set: carton, sleeve, pouch, or tray, and how many units that implies. If you sell a course of use, make the count and ritual clear without promising outcomes. If you sell a single trial, the unit itself may need to carry more of the brand. Ask how the pack sits on a shelf, photographs, and survives shipping. If the inner pack is already branded, keep it from competing with the outer wrap.
What to send a manufacturer
Send a one-page brief, any existing formula or a description of texture and scent, pack preferences and what you are still deciding, target user and channel, artwork or a sketch of the unit and outer pack, and questions you want answered before filling. Ask what they still need from you, and what they cannot confirm until formula and pack are together. If you have a reference pack, send a photo and say what you like about it.
