Imagine the brotion has a problem of stability, in two weeks all the ingredients degradate and loose all effectivity, okay?
Imagine it can regrow a full Norwood back if the ingredients havent degradated, but doesn't do sh*t once two weeks have happened since the manufacturation of the brotion, there is absolutely zero point in releasing this to the market for two reasons:
1) the brotion works, but it has issues with stabiltiy, if you release it with problems it will get bad reputation, once you fix it it will reach a smaller market.
2) ppl that'd buy it, would look at the expiration date and alwys pick the highest one,
Well if the lotion works but it has such poor stability that in just 2 weeks it looses its effectiveness, the reputatio. Of the brotion will be very low even if the ingridients work.
