Hi,

Welcome to icliniq.com.

The darker one is the lesion of lichen sclerosus chronicus. For this, you may apply Tenovate GN cream (combination of Clobetasol Propionate and Neomycin sulfate) over it twice daily for two weeks. The skin-colored lesion may be an acquired nevus. A skin biopsy is required for confirmation. A biopsy is more important if it suddenly changes the size and character. Otherwise, it is a benign lesion and nothing needs to be done. Pain is not a symptom of these lesions, but may be coincidental.

Hope it helps.

Thank you.
