How should I store this cream to keep it effective, and does it expire?

To maintain the cream's consistency and the stability of its plant-based ingredients, store it in a cool, dry place away from direct sunlight and heat sources—such as a bathroom cabinet or a bedroom shelf, not on a windowsill or next to a radiator. The emulsion base (water combined with oils) can separate if repeatedly exposed to high temperatures, and the essential oil (lavender) aroma may fade faster. Keeping the lid tightly closed after each use prevents contamination and slows oxidation.

Like all cosmetics, this product has a limited shelf life. Check the packaging for a Period After Opening (PAO) symbol—typically an open jar icon with a number and "M" for months—indicating how long the product remains usable after first opening. Unopened, it should be used by the expiry date printed on the tube or box. If the cream changes color, develops an off smell, or the texture becomes grainy or watery, it's best to discard it. Using expired cosmetics can reduce efficacy and increase the risk of skin irritation.
