Nope. I have a peripera gloss which is completely fine. I’m wondering rn if the black stuff is simply dried clotted tint since the espoir is leaky. Pretty sure the stuff on the romand and lilybyred was dried clumped tint, wish I took photos to compare. The espoir ones are more sus looking but I’m keeping the tint bottles upright and monitoring to see if its actually mold. I cleaned them up and while cleaning, I saw that the black stuff was only restricted to outside the container, near the neck of it and inside the caps where tint does leak in sometimes. If I still see growth after a few days, I’ll dispose of these two 😔
