I have been developing moles since childhood?
Hello, doctor: I have about 20 moles on my face, which is quite surprising, right? I'm not lying to you! It's really troubling...
I've been getting moles since I was a child, especially in the summer.
Even when I apply sunscreen, it doesn't seem to help much because I've observed that after just 3-4 hours of sun exposure, small brown spots start to appear on my face, and after a while, they gradually turn into moles.
This is quite scary.
Is there something wrong with my skin? Also, could you please advise me on what to eat to promote hair growth? Thank you for your response.

Hello! 1.
These small black moles become more noticeable after exposure to ultraviolet light, so please try to minimize the duration and frequency of sun exposure.
2.
The treatment for hair loss should be tailored according to the underlying cause.
Sincerely, Dr.

More Info
Understanding skin moles, or nevi, is essential for maintaining skin health and addressing any concerns you may have. Moles are common skin growths that can appear anywhere on the body. They are usually brown or black and can vary in size and shape. While most moles are harmless, changes in their appearance can indicate potential health issues, particularly skin cancer.
Causes of Moles
Moles develop when skin cells called melanocytes grow in clusters instead of being spread throughout the skin. The primary factors contributing to the formation of moles include:
1. Genetics: Family history plays a significant role in the number and type of moles you may develop. If your parents or siblings have many moles, you are likely to have them too.
2. Sun Exposure: Ultraviolet (UV) radiation from the sun can stimulate the production of melanin, leading to the formation of new moles. It seems you have observed that your moles increase with sun exposure, which is a common phenomenon. Even with sunscreen, prolonged sun exposure can lead to the development of new moles or darkening of existing ones.
3. Hormonal Changes: Hormonal fluctuations during puberty, pregnancy, or menopause can also affect the appearance of moles. This is why some individuals notice changes in their moles during these life stages.
Concerns Regarding Moles
While most moles are benign, certain characteristics can indicate a need for further evaluation. You should monitor your moles for the following changes, often referred to as the ABCDEs of melanoma:
- 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, tan, red, white, or blue.
- Diameter: The mole is larger than 6mm (about the size of a pencil eraser).
- Evolving: The mole changes in size, shape, or color over time.
If you notice any of these changes, it is crucial to consult a dermatologist for a professional evaluation.
Care Tips for Moles
1. Sun Protection: Since you have noticed that sun exposure leads to the development of new moles, it is essential to practice sun safety. Use broad-spectrum sunscreen with an SPF of 30 or higher, wear protective clothing, and seek shade during peak sun hours.
2. Regular Skin Checks: Perform regular self-examinations of your skin to monitor existing moles and identify any new ones. Keeping a record of your moles can help you notice any changes over time.
3. Consult a Dermatologist: If you are concerned about the number of moles or any changes in their appearance, it is advisable to see a dermatologist. They can provide a thorough examination and recommend any necessary treatments or removals.
Hair Growth and Nutrition
Regarding your question about hair growth, a balanced diet plays a crucial role in promoting healthy hair. Here are some dietary tips that may help:
- Protein: Hair is primarily made of protein, so ensure you consume adequate amounts of lean meats, fish, eggs, beans, and nuts.
- Vitamins and Minerals: Vitamins A, C, D, E, and B vitamins (especially biotin) are essential for hair health. Incorporate fruits, vegetables, whole grains, and healthy fats into your diet.
- Iron and Zinc: These minerals are vital for hair growth. Foods rich in iron include spinach, lentils, and red meat, while zinc can be found in nuts, seeds, and whole grains.
In conclusion, while moles are generally harmless, it is essential to monitor them for any changes and practice sun safety to prevent new ones from forming. If you have concerns about your skin or hair, consulting a healthcare professional is always a good idea.
