Hello,
This spot can be due to dry skin, eczema, seborrheic dermatitis or psoriasis. Seborrheic dermatitis is usually caused by overgrowth of Malassezia furfur. This skin disease commonly affects adolescents and young adults, especially in warm and humid climates and is aggravated by sweating and humidity.
To confirm the diagnosis, get it examined from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Looks like a localized seborrohea.Could be a contact dermatitis to spectacles or other allergens.A little vaseline could do the trick in dry seborrohea. Do consult yor doc.
