When Rimmel London packaging is inside bags, soft-touch or rubberized surfaces often break down because of heat, friction, or humidity, leaving behind a sticky residue. A lot of makeup brands that use matte or velvet-finish plastics have this problem.
Wipe the box with a cloth that is a little wet with isopropyl alcohol or dish soap that is mixed with water.
Then make sure it is dry. Do not get the product or the caps wet, or else the formula inside might be ruined.
Put the thing in a small makeup pouch or wrap it in paper to keep it from happening again. This will make sure that there is less friction.
Keeping cosmetics away from heat and strong sunlight slows down the breakdown of the coating.
