When it comes to changes in moles or skin lesions, it's essential to approach the situation with caution and an understanding of the underlying biology. The shedding of black skin from a mole, as you described, can be concerning, but it doesn't always indicate a serious issue.
Moles, or nevi, are common skin growths that can vary in color, shape, and size. They are typically benign, meaning they are not cancerous. However, changes in a mole, such as color, texture, or size, can sometimes indicate a need for further evaluation. In your case, the black skin peeling off and revealing a brown color underneath, while maintaining the same shape and size, could be a natural occurrence. Moles can undergo changes due to various factors, including hormonal changes, sun exposure, and even friction from clothing.

The fact that you are not experiencing any pain, itching, or bleeding is a positive sign. These symptoms can often accompany more serious conditions, such as melanoma, which is a type of skin cancer. However, it is crucial to monitor the mole for any further changes. If the mole begins to change in shape, color, or size, or if you notice any new symptoms, it is advisable to consult a dermatologist.

In terms of the biological process, the outer layer of skin, known as the epidermis, can sometimes shed or peel away due to various reasons, including irritation or natural exfoliation. This can happen with moles as well, especially if they are subjected to friction or irritation. The underlying tissue may appear different once the outer layer is removed, but this does not necessarily mean that the mole is becoming cancerous.

It's also worth noting that while some online sources may suggest that changes in moles are indicative of malignancy, this is not always the case. The "ABCDE" rule is a helpful guideline for assessing moles:
- Asymmetry: One half of the mole does not match the other.

- Border: The edges are irregular, ragged, or blurred.

- Color: The color is not uniform and may include shades of brown, black, or even red, white, or blue.

- Diameter: The mole is larger than 6mm (about the size of a pencil eraser).

- Evolving: The mole is changing in size, shape, or color.

If your mole does not exhibit these characteristics, it may simply be undergoing a benign change. However, if you have any doubts or concerns, it is always best to err on the side of caution and seek professional medical advice. A dermatologist can perform a thorough examination and, if necessary, a biopsy to rule out any serious conditions.

In summary, while the shedding of black skin from your mole may be a natural occurrence, it is essential to monitor it closely for any changes. If you notice any concerning symptoms or if the mole changes in any way, consult a dermatologist for a professional evaluation. Regular skin checks and being aware of changes in your skin can help ensure early detection of any potential issues.
