I'm considering packaging for my skin care line. Compared with of amber, blue, green and clear glass, are deeper violet glass bottles really worth the extra price?
Does the brand matter? I've seen Miron Violet Glass Bottles featured on some write-ups.
By using deep violet glass bottles does it mean there is no need for preservative (I'm still pro preservative btw)? Or does it only mean it will have a longer shelf-life?
Greatly appreciate your feedback.
