Do you all check the expiration dates on your lip tints?

Even if the expiration date has passed or is slightly overdue, as long as the contents are intact, it doesn't affect usage. I'm not forcing you, but it feels like a waste to just throw away lip tint.

Rather than just throwing it away even if the expiration date has passed, I recommend using it instead of paint when drawing.

Also, when I use lip tint, I always make sure to finish the current one before opening a new one. That way, you can prevent spoilage or contamination. If the contents have already gone bad, I have no choice but to remove the opening, empty the contents completely, and discard it. That is the only way to ensure hygiene.
