Talk to Dermatologist on Skin Discoloration / Hyperpigmentation

The individual is experiencing hyperpigmentation (darkening or tanning) of sensitive body areas, specifically the underarms and genital region (penile/groin area). The skin in these regions appears darker than the surrounding body skin, possibly brown to black in color, and may or may not be accompanied by itchiness, irritation, or thickening of the skin.
