hyperpigmentation
Excess melanin patches
Hyperpigmentation is darkening of the skin caused by excess melanin production.
It appears as patches, spots, or uneven skin tone, often triggered by sun exposure, hormonal changes, inflammation, or injury.
Common forms include age spots, melasma, and post-acne marks.
She used vitamin C serum to fade the hyperpigmentation on her cheeks.
