Common Skin Problems in People with Dark Skin

Common skin problems for people with darker skin tones

People with dark skin may experience a range of skin issues that are unique due to their higher levels of melanin. It is important to note that while skin conditions affect people of all skin tones, certain concerns may be more noticeable or present themselves differently in those with darker skin. Below are some common skin problems in people with dark skin:

Hyperpigmentation: This is the most common of all the skin problems that afflict people of color. Darker skin is more prone to hyperpigmentation, which can result from conditions such as acne, eczema, or injury. Dark spots or patches may develop be more persistent and noticeable.
Keloids: Darker skin has a higher tendency to form keloids, which are raised overgrowths of scar tissue. Keloids can develop after minor injuries or surgical procedures and may be more prominent in individuals with darker skin tones.
Post-inflammatory Hyperpigmentation (PIH): PIH occurs after skin inflammation or injury, leaving behind dark spots or discoloration. Darker skin tones are more susceptible to PIH, and the pigmentation changes can last longer.
Acne: Acne can affect individuals of any skin tone, but the aftermath (such as hyperpigmentation or keloid scarring) may be more noticeable in people with darker skin.
Acanthosis Nigricans: This condition is characterized by dark, thickened, velvety patches of skin, often around the neck, armpits, or other body folds. It is associated with insulin resistance and obesity. According to the American Academy of Dermatology (AAD). Acanthosis nigricans can also be an early warning sign of diabetes, hormonal problems such as PCOS and even skin cancer.
Hypopigmentation Disorders: In addition to hyperpigmentation, disorders leading to loss of skin color (such as vitiligo) may be more visually striking in individuals with darker skin.
Rosacea: Easy to miss in people with darker skin. In lighter skinned people, it causes redness. In people of color, the affected skin can often appear darker and brown in color.
Ashy Dermatosis: This skin problem is more common in individuals with darker skin. It leads to gray or ashy patches on the skin, usually on the legs.
Pseudofolliculitis Barbae (Razor Bumps): Due to the curly nature of hair in people with dark skin, shaving can sometimes lead to ingrown hairs, resulting in razor bumps and inflammation.
Eczema (Atopic Dermatitis): Eczema can affect individuals of all skin tones, but it might be more noticeable in dark skin due to hyperpigmentation or hypopigmentation associated with the condition. The skin may appear ashy, and scratching can lead to post-inflammatory hyperpigmentation.
Psoriasis: Psoriasis can manifest differently in people with darker skin. The plaques may be darker or more pigmented, making them easily mistaken for other skin conditions.
Dermatosis Papulosa Nigra: This condition is characterized by small, dark bumps, often seen on the face, neck, or chest. It is more common in individuals with darker skin.
Lichen Planus: Dark skin may exhibit hyperpigmented or hypopigmented patches due to lichen planus, an inflammatory skin condition.
Tinea (Fungal Infections): Fungal infections, such as tinea versicolor, can cause changes in skin pigmentation. In darker skin, these infections may result in hypopigmented or hyperpigmented patches.
Seborrheic Dermatitis: This chronic inflammatory condition can affect the scalp, face, and other areas, leading to redness, scaling, and sometimes hyperpigmentation, particularly in individuals with darker skin.
Folliculitis: Inflammation of hair follicles can result in dark spots or keloid scars in people with dark skin, especially if the condition becomes chronic.
Moles and Melanoma: While people with darker skin are less prone to developing melanoma, when it occurs, it is often diagnosed at a later, more advanced stage. It’s essential for individuals with dark skin to regularly check for changes in moles and seek prompt medical attention if any are noticed.
Allergic Contact Dermatitis: Pigmented skin may respond to allergens or irritants with hyperpigmentation or hypopigmentation, creating distinctive patterns on the skin.
Granuloma Annulare: This chronic skin condition can cause raised, reddish or skin-colored bumps in a ring pattern. In individuals with dark skin, the lesions may appear hyperpigmented.
Xerosis (Dry Skin): People of color may be more prone to dryness. This leads to conditions like xerosis, which can cause itchiness, scaling, and discomfort.
Hidradenitis Suppurativa: This chronic skin condition involves the inflammation of hair follicles, resulting in painful nodules, lumps and abscesses. In people with dark skin, scarring and hyperpigmentation may be more prominent.

It’s important for individuals with dark skin problems to seek dermatological care from professionals who understand the unique challenges and characteristics of darker skin tones. Early diagnosis and appropriate management can help address these skin concerns effectively. Additionally, proper skincare practices, including sun protection, can contribute to maintaining healthy skin in individuals of all skin tones.

Darker Skin Absent from Medical Texts

According to a recent paper, people with black and brown skin tones are underrepresented in medical textbooks that teach doctors on how to recognize skin disease. The shortfall in darker skin representation could contribute to racial disparities in diagnosis and treatment. The research was conducted via the use of machine learning and AI.

Skin Tone Analysis for Representation in Educational Materials

The original paper was published in August 2023 and included reserchers from the US and Kenya. It is titled: “Skin Tone Analysis for Representation in Educational Materials (STAR-ED) using machine learning”. They analyzed skin-related pixels and non-skin related pixels and made comparisons using the Jaccard index. STAR-ED works on a wide range of file formats, including pdf, png, jpeg, pptx and docx.

One of the lead authors is Dr. Roxana Daneshjou, a dermatologist and biomedical data scientist from Stanford University. In her words:

Unfairness in the teaching materials equates to unfairness in society.
There’s lots of news out there of bias in AI models, but in this case we’ve trained an AI model that detects human bias.

STAR-ED is open source. Both the code and dataset are available for download via GitHub.

Underrepresentation of Darker Skin Tones

The research team trained STAR-ED on thousands of images in medical textbooks, lecture notes, presentation slides, and journal articles. They found that only one in ten images throughout these materials is in the black-brown range on the Fitzpatrick Scale used to evaluate skin tone.

The researchers envision this unique STAR-ED technology to be used as a tool for dermatology educators and publishers. It will help assess educational materials and automatically identify and significant lack of diverse skin tone representation.

Besides the technology’s use for various cosmetic concerns, there is an even bigger issue at play. At present, the diagnosis of life threatening conditions such as skin cancer (melanoma and squamous cell carcinoma) is often delayed in patients of color, leading to increased mortality rates.

Some dermatologists are taking the matter into their own hands. Dr. Jenna Lester started the Skin of Color Program at the University of California, San Francisco in 2018. She wanted to train dermatology residents in treating skin of color. Skin conditions such as eczema, psoriasis, inflammation, acne and hyperpigmentation show up differently in people of different colors and ethnicities.

In a recent article, well known dermatologist Dr. Suneel Chilukuri proclaimed that the ADVATx laser is the safest and most effective for dark skin tones. It is manufactured by Advalight of Denmark.

ADVATx Laser for Dark Skin Tones

The ADVATx laser is the world’s first and only solid-state laser that produces both of the following two wavelengths of light:

589 nanometers (yellow).
1319 nanometers (infrared).

For comparison, Nd:Yag lasers that are the most common for use in people with dark skin operate at a wavelength of 1064 nanometers.

Per Dr. Chilukuri:

The 1319 nm is completely color blind so you can treat all skin types.

On the company’s Instagram, you can see numerous before and after photos of satisfied patients.

The cutting-edge ADVATx laser is also unique in that it can be used to treat patients of all skin tones and types. It is also non-invasive and virtually painless, with little to no downtime.

How does the ADVATx Laser Work?

The ADVATx laser works by delivering pulses of laser energy to the skin. The 589 nanometer wavelength targets vascular lesions and acne bacteria, while the 1319 nanometer wavelength heats the dermis, stimulating collagen and elastin production. This results in improved skin tone, texture, and overall appearance.

The ADVATx laser is a versatile and effective treatment for a wide range of skin concerns. It is also safe and well-tolerated by most patients.

Here are some of the benefits of ADVATx laser treatments:

Non-invasive and virtually painless.
Little to no downtime.
Can be used to treat patients of all skin tones and types.
Effective for a wide range of skin conditions, including vascular lesions, acne, scars, warts, pigmentation, wrinkles, fine lines, enlarged pores, and crepey skin.
Safe and well-tolerated by most patients.
Please consult a qualified dermatologist or aesthetic physician if you want to learn more about ADVATx laser treatments.

ADVATx technology utilizes nano pulses to create energy. The resulting waves are of such a short frequency and time (duration), that this laser can effectively treat browns and reds without being absorbed by the skin. This makes it especially beneficial for those with melasma and hyperpigmentation. The 1319 nm wavelength is attracted to water instead of melanin in people with darker skin, thus preventing any burns of injuries.
