Usually use
Silicone Film (Long-Wear, Hard, Isododecane Base) but I feel it is not durable. Once you eat something, it's all gone. if you want to change to
Vinyl Film (Medium Wear, Soft) (VP/Hexadecene Copolymer) interchangeable? How can you endure more? or must be used in conjunction Will the texture of the lipstick come out different? Do I need to adjust any formula? Then when pouring the lipstick into the mold, some of the sticks are air bubbles, small holes along the lip sticks. what is the reason thank you
