Quick answer

Store your The Sweetheart lashes in their original tray with the lid closed, in a cool, dry place away from direct sunlight. This keeps the pre-placed adhesive intact and the curl shape preserved for multiple reuses.

Why proper storage matters for The Sweetheart lashes

The Sweetheart lashes feature PrepTECH™ patent-pending technology with pre-placed adhesive. If stored incorrectly—like tossing them loose in a makeup bag—the adhesive can pick up dust and lint, or the curl can flatten. A few seconds of care after each wear can double or triple how many times you can reuse them.

How to store The Sweetheart lashes for maximum reuse

  1. 1. Clean the lashes after each wear: Gently remove any leftover adhesive or makeup from the lash band using a lint-free cloth or cotton swab dipped in oil-free makeup remover. Avoid pulling or tugging the lash fibers. Skipping cleaning can leave residue that attracts dust and makes the next application less secure.
  2. 2. Let the lashes air dry completely: Place the cleaned lashes on a clean tissue or paper towel, curl side up, and let them dry for 5–10 minutes. Never store them while damp—moisture can weaken the pre-placed adhesive and cause mold. Damp storage is the fastest way to ruin the adhesive. Always check they are fully dry.
  3. 3. Return lashes to the original tray: Carefully place each lash cluster back into its molded slot in the original tray, matching the curve of the tray. Close the lid securely to keep out dust, pet hair, and makeup residue. The tray is designed to protect the curl shape. Storing them flat or in a bag can flatten the C/D curl.
  4. 4. Store in a cool, dry place away from sunlight: Keep the closed tray in a drawer, vanity, or cabinet where temperature stays consistent. Avoid bathrooms (humidity) and windowsills (UV light). Heat and moisture degrade the adhesive and can warp the lash fibers. A bedroom drawer is ideal. A bathroom cabinet is not—humidity from showers can shorten lash life.
  5. 5. Avoid stacking heavy items on top: Do not place makeup palettes, brushes, or other heavy objects on top of the lash tray. Pressure can bend the lash clusters out of shape or crack the tray. Store the tray in its own compartment or on top of other items, not under them.
