I have a 1 cm long by .0.5 cm wide hyperpigmented atropic box scar on and under my labiomental crease. I think it is the result of a combination of multiple scars compounded and maybe a tiny mole. I say this because at times, the scar looks somewhat layered up close and different in different angles of light. It darkens and lightens on different days quite randomly and is unfazed by skin lighteners. Subcison, microneedling and peels don't work. In 2024 I know there is a way to clear this.
