People with darker skin tones possess a higher concentration of melanin, which provides a greater level of natural protection against the damaging effects of ultraviolet radiation. While this means that certain types of skin changes are statistically less frequent in individuals with more pigment, it does not mean that worrying moles cannot occur. Understanding the specific ways in which moles present on darker skin is vital for ensuring that any significant changes are identified and managed appropriately.

The protective role of melanin and its limitations
Melanin is the natural pigment that determines the colour of a person’s skin, hair, and eyes, and it acts as a built-in filter against ultraviolet light. In people with darker skin, the melanocytes produce more eumelanin, which is particularly effective at absorbing and scattering UV rays before they can damage the DNA of skin cells. This natural defence significantly reduces the likelihood of developing moles that are triggered by sun exposure compared to individuals with very fair skin. However, this protection is not absolute, and skin cells can still undergo changes due to other factors such as genetics, internal health shifts, or trauma to the skin surface.
Where skin changes commonly occur in darker-skinned individuals
While sun-exposed areas are the primary concern for lighter skin tones, worrying moles in darker-skinned people are frequently found in areas that receive little to no sun exposure. This includes the palms of the hands, the soles of the feet, and under the fingernails or toenails. Because these areas have less natural pigment than the rest of the body, they can be more susceptible to certain types of cellular changes. Medical guidelines in the United Kingdom emphasise that a thorough skin check for a person with dark skin must include these specific sites to be effective.
Identifying irregular features on darker skin
On darker skin, a mole may be a very deep brown or black colour, which can make it more challenging to identify traditional warning signs like colour variation. In these cases, asymmetry and irregular borders become even more important indicators to watch for. A mole that stands out because it is significantly darker than any others on the body, or one that has a jagged edge, should be monitored closely. Additionally, a new dark streak or patch appearing under a nail that is not caused by an injury is a specific sign that warrants a professional clinical assessment.
The importance of regular checks regardless of skin tone
The lower statistical frequency of certain skin conditions in darker-skinned populations can sometimes lead to a false sense of security, which may result in changes being noticed later than they otherwise would be. Regular monthly self-examinations are just as important for people with dark skin as they are for those with fair skin. By becoming familiar with the typical appearance of their moles and the skin on their palms and soles, individuals can identify any new or evolving marks early. Awareness of what is normal for one’s own body is the most powerful tool in maintaining skin health across all ethnicities.
Professional assessments for diverse skin types
When a person with dark skin seeks a professional review of a mole, healthcare professionals use the same diagnostic tools, such as a dermatoscope, to look beneath the surface pigment. A specialist will look for specific patterns of pigment distribution that are characteristic of healthy skin regardless of the baseline skin tone. Because some skin changes can look different on darker skin—appearing as purple, grey, or dark brown patches rather than red or pink—it is important for individuals to describe any changes in sensation, such as itching or tenderness, during the consultation.
Sun safety and skin health for all
Even though darker skin has more natural protection, the NHS still recommends the use of sunscreen and protective clothing during periods of intense sun exposure. This is not only to protect any existing moles but also to prevent other skin issues such as hyperpigmentation or uneven skin tone. Maintaining the health of the skin barrier through moisturisation and protection supports the overall stability of moles and makes it easier to spot any genuine changes. Healthy skin is the best canvas for effective monitoring throughout a person’s life.
Conclusion
While people with darker skin have a higher level of natural UV protection, they are still at risk for certain types of skin changes, particularly in areas like the palms and soles. Being proactive with monthly skin checks and paying attention to the soles of the feet and the nails is essential for long-term health. Understanding that everyone needs to monitor their skin, regardless of their tone, ensures that any issues are caught and managed promptly.

Do I need to use sunscreen if I have dark skin?
Yes, while you have more natural protection, sunscreen helps prevent DNA damage and other skin issues like melasma or post-inflammatory hyperpigmentation.
What does a concerning mole look like on dark skin?
It often appears as an asymmetrical patch with irregular borders or a very dark spot that looks different from all your other moles.
Should I be worried about a dark line in my fingernail?
If a dark line appears in a nail and is not caused by an injury, or if it starts to widen or change, you should have it checked by a professional.
Are moles on the soles of the feet more dangerous?
They are not inherently more dangerous, but because they are in an area with less pigment, any changes there should be monitored very closely.
Can darker skin get sunburnt?
Yes, while it takes longer and more intense exposure, darker skin can still burn, leading to pain, peeling, and potential damage to skin cells.
Why are my moles darker than my friend’s moles?
The colour of a mole is determined by the amount of melanin your body produces; naturally darker-skinned people will usually have darker moles.
Is it harder for doctors to check moles on dark skin?
A doctor trained in using a dermatoscope can see the patterns within a mole regardless of the skin’s baseline pigment level.
