1. Presentation and Luxury Feel:
Jars often feel substantial, heavy, and luxurious. The act of unscrewing a lid and dipping into a rich cream can be a sensory, ritualistic experience that many consumers associate with high-end, pampering skincare.
2. Protection of the Formula:
Light and Air Exposure: While not as sealed as a pump, a jar with a tight-fitting lid still offers good protection from light, which can degrade some active ingredients like Vitamin C and retinol.
Physical Protection: The sturdy walls of a jar protect the product from being crushed or damaged during shipping or handling.
