Thank you for your respond i appreciate this i will look into seen a dermatologist.
Hello,
Having dark skin in the groins and underarms is normally found in some individuals because of the sweating associated in the area. In some others, this darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.
Treatment involves hydroquinone, azelaic acid, corticosteroids, tretinoin cream and laser treatment. Please discuss these options with your dermatologist before using them.
Hope it helps. Take care and please do keep me posted on how you are doing or if you have any additional queries. Warm regards.
