What's the best way to store this lip balm to prevent it from melting or becoming grainy?

Like most wax-based lip balms, this product is sensitive to temperature fluctuations. To prevent melting or a change in texture (like becoming grainy or separating), store it in a cool, dry place away from direct sunlight and heat sources. Avoid leaving it in a hot car, near radiators, or in a pocket close to your body for extended periods. If it does melt and resolidifies, its efficacy isn't necessarily compromised, but the texture might feel less smooth. If it becomes grainy, it's often a sign of the oils and waxes crystallizing due to repeated heating and cooling; it's still safe to use but may be less pleasant. For travel, keep it in a bag rather than a tight pocket. At home, a drawer or cupboard is ideal. Unopened, such products typically have a shelf life of 2-3 years. Once opened, use common sense: discard if the scent changes dramatically (becomes rancid), the color alters significantly, or if you observe any mold—though preservatives in cosmetic formulas make the latter very unlikely with normal use.
