Brown spots and itchy skin: what should you do?

A brown spot on itchy skin is an area of dark pigmentation found on a part of the skin that is irritated or prone to a tingling sensation. The spot results from an excess of melanin, while the itching may be linked to dryness, inflammation, or an allergic reaction affecting the affected area. This type of hyperpigmentation can appear on the face, hands, back, or legs, and has many causes: sun exposure, skin ageing, skin conditions, or external irritants. Identifying the underlying cause is essential for choosing the right treatment and alleviating both the discolouration and the discomfort.

Itchy brown spots can have several causes. Here are the factors known to cause dark spots on the skin:

Sun exposure

Melanin is the pigment that protects our skin from the sun’s rays. Prolonged exposure to UV rays stimulates the production of this pigment, which can cause the appearance of brown spots. Furthermore, UV rays can also weaken the skin, dry it out, and cause irritation, which explains the associated itching. UVB and UVA rays damage the DNA of skin cells. To defend itself, the skin increases melanin production, but this response can become excessive and disorganised, forming a brown spot.

Skin ageing

As we age, skin cells regenerate less effectively and melanin production can become less uniform. This can lead to the formation of brown spots in localised areas where melanocytes are more active. In addition, mature skin tends to be drier and produce less protective sebum, which can contribute to feelings of tingling, tightness and itching.

An allergic reaction

Certain localised allergic reactions can lead to an overproduction of melanin in the skin, leaving behind a dark, itchy spot. In such cases, the inflammation activates immune cells and stimulates the skin’s nerves, resulting in intense itching.

Hormonal imbalances

Significant hormonal fluctuations, particularly in oestrogen and progesterone, can stimulate melanocytes. In fact, hormones stimulate the hormone receptors on melanocytes, increasing melanin production. This can lead to the appearance of brown spots, particularly on the face. In cases of hormonal imbalance, the skin can also become more sensitive and fragile, which also explains the itching.

Fungal infections

Certain types of fungal infections, such as pityriasis versicolor, can cause brown spots or, conversely, depigmented patches. In this case, fungi disrupt melanin production by releasing enzymes that interfere with melanogenesis (melanin production) and destroy certain protective lipids in the skin. They thus attack the outermost layer of the epidermis, causing redness and itching.

A brown spot on itchy skin may be accompanied by various signs that help better understand its origin and progression. Some symptoms are benign, while others may require medical attention:

• Colour: The brown spot may darken over time, depending on sun exposure, which stimulates melanin production.

• Size: The spot may gradually increase in size due to melanocyte hyperactivity caused by UV rays or a hormonal imbalance.

• Feeling of dryness: Dry skin loses its protective hydrolipidic film. This increases skin sensitivity and promotes itching.

• Urge to scratch: The urge to scratch is often caused by the release of histamine and other inflammatory mediators that activate the skin’s nerve endings, creating irritation.

• Peripheral redness: It is common to see redness appear around the brown spot. This is caused by vasodilation of the blood vessels. This sign generally indicates an allergic reaction or local irritation.

• Presence of blisters: in the event of an allergic reaction or underlying infection, blisters may form on the spot. These are caused by an immune defence reaction against the pathogen or irritant causing the skin imbalance.

In any case, when a brown spot starts to itch, it’s important to monitor its progression to rule out any risks to skin health. If in doubt, don’t hesitate to consult your primary care physician or a dermatologist to assess your condition.

Itchy brown spots can be effectively prevented by adopting a few good habits: 

1. Protect yourself from the sun: Sun exposure can worsen the appearance of brown spots. Remember to wear a hat or sunglasses to protect your skin, especially on sunny days. You can also apply sunscreen with an SPF suited to your skin type, for peace of mind all day long. Depending on your preference, choose products with light, non-greasy textures for optimal comfort!

2. Avoid sun exposure during peak hours: the sun is strongest between noon and 4 p.m. If possible, try to avoid being out during these hours. If you must go out, take the opportunity to take a short walk in the shade of trees or under a parasol. It’s also nice to spend time indoors, out of the sun, with a good book or a cold drink.

3. Adopt a moisturising routine: dehydrated skin is more prone to irritation and itching. To deeply nourish and hydrate it, apply a gentle moisturiser every day. Do this whenever you like—after a shower or before bed—for a moment of relaxation and self-care. Hydration helps strengthen the skin barrier and prevent irritation.

4. Avoid skin irritants: if you have sensitive skin, avoid soaps or shower gels that are too harsh. Opt for gentle products that are kind to your skin. If necessary, also reconsider your laundry detergent to protect your skin from harsh chemicals that may trigger skin reactions such as dark spots and itching. 

5. Try not to scratch: If you’re already experiencing itching, resist the urge to scratch. It’s difficult, but scratching can make things worse by irritating the area and leaving marks on your skin. If the spot is itchy, you can apply a soothing treatment to help you feel better.

If you have a brown spot accompanied by persistent itching, it is recommended that you consult a healthcare professional to rule out any underlying dermatological causes.

Taking care of yourself is essential, so don’t forget to listen to your skin and treat it gently. Every step, no matter how small, can help you feel better in your own skin. And remember, itchy brown spots don’t define your beauty—it’s the care you give yourself that makes all the difference. Take your time and be patient with your skin, while treating yourself to pleasant daily skincare routines.
