Age spots

What are age spots?

Age spots (lentigines seniles), especially sun-induced age spots (lentigines solares), are harmless pigment changes to the skin. They are caused by years of UV exposure and appear primarily on areas exposed to the sun, such as the face, hands, forearms, and décolletage.

Unlike freckles, age spots generally do not fade in the winter. They usually appear starting in middle adulthood and manifest as flat, light- to dark-brown spots. Age spots are a sign of skin aging and are not a sign of illness, but they can be considered unsightly for cosmetic reasons.

Age spots: causes and risk factors for moles

Age spots are caused by excessive production of the skin pigment melanin. Skin pigmentation disorders are primarily caused by long-term exposure to UV radiation. People with fair skin are affected more often than those with dark skin, and women more often than men. If the skin is repeatedly exposed to the sun or artificial UV light (e.g., in a tanning bed) over the course of many years, increased pigment deposits form in certain areas. These appear as brownish, sharply defined spots, primarily on the hands, face, and other areas exposed to the sun.

In addition to UV radiation, age is one of the most important risk factors, since the skin becomes less resistant to external influences over the years and pigmentation disorders are more likely to occur. Genetic predisposition also plays a role. Some people are more prone to age spots than others. Other contributing factors include hormonal changes (e.g., due to pregnancy or birth control pills), oxidative stress caused by an unhealthy diet, smoking, or environmental toxins, as well as an overall unhealthy lifestyle.

Symptoms of age spots: Recognizing signs and warning signals

Typical symptoms of age spots include:

• flat, smooth, oval, or irregularly shaped patches on the skin
• Light brown to dark brown color, depending on skin type and UV exposure
• They start out small (a few millimeters), but can grow larger over time
• often on areas exposed to the sun, such as the face, hands, arms, shoulders, décolletage, and the backs of the feet
• no symptoms such as pain, itching, or inflammation

Changes in Skin Pigmentation: When Should You See a Doctor?

Age spots are generally harmless and are purely a cosmetic issue. However, if a spot suddenly changes—develops irregular edges, becomes noticeably darker, or starts to itch or bleed—you should see a doctor. Such changes may indicate a more serious skin condition. An early examination by a dermatologist will provide you with clarity.

Age spots: Diagnosis and examinations

To accurately diagnose age spots, a clinical examination is performed by a dermatologist. During the examination, the pigmented spots are examined using a dermatoscope and palpated to distinguish harmless age spots from other skin changes such as moles, melasma, or skin cancer. In rare cases, a tissue sample (biopsy) is taken to ensure that the skin lesion is not malignant.

It is important to have any new or changing skin lesions examined by a doctor. You should take dark, irregularly shaped, or rapidly growing spots particularly seriously and have them checked promptly. Regular skin checkups can help detect any malignant changes early on.

Age spots: prevention, early detection, prognosis

How can I prevent age spots?

Prevention is better than cure. Ways to Prevent Age Spots:

1. Adequate sun protection

• Use sunscreen daily with a sun protection factor (SPF) of at least 30, ideally SPF 50.
• Apply sunscreen not just in the summer, but all year round—especially on your face, hands, and other areas exposed to the sun.
• Avoid the midday sun (between 11 a.m. and 3 p.m.), as UV radiation is at its strongest during those hours.
• When the sun is out, wear protective clothing, such as long sleeves, hats, or special UV-protective fabrics.

2. Gesunde Hautpflege und Ernährung

• Antioxidants such as vitamins C and E help fight free radicals and protect the skin.
• Moisturizing skincare products (such as hyaluronic acid and niacinamide) can strengthen the skin barrier.
• Gentle exfoliants (e.g., those containing fruit acids) promote skin renewal and help prevent pigmentation disorders.

3. Gesunde Lebensweise

• Cut back on smoking and alcohol, as both accelerate skin aging.
• A balanced diet rich in fruits, vegetables, and omega-3 fatty acids protects the skin from the inside out.
• Minimize stress, because chronic stress can accelerate skin aging and contribute to pigmentation problems.

4. Keine Selbstversuche mit Hausmitteln oder aggressiven Behandlungen

• Lemon juice or other harsh home remedies can irritate the skin and may even make pigmentation spots worse.

Early detection

Age spots often appear in people over the age of 40 and are a normal sign of aging. Early detection of age spots is important for identifying potential skin changes that could indicate skin cancer in a timely manner. Regular skin examinations and monitoring changes in the size, shape, or color of moles can help detect abnormalities early on. If you suspect you have skin cancer, you should see a dermatologist immediately.

Treatment of age spots: How can I treat pigmentation disorders?

Age spots can be treated in various ways. Common options include:

• Laser Treatments: Laser therapy is an effective method for removing age spots . In this procedure, the affected skin is treated with a laser beam that penetrates either the epidermis or deeper layers of the skin, depending on its intensity. The laser breaks down the pigment deposits, which are then eliminated by the body. Several sessions are usually necessary to achieve optimal cosmetic results. Possible side effects include redness, swelling, a burning sensation, and areas of hypopigmentation. During the healing phase, consistent UV protection is essential to prevent post-inflammatory hyperpigmentation.
• Skin-lightening creams: Skin-lightening creams containing active ingredients such as hydroquinone or retinoids can inhibit melanin production and thus gradually reduce pigmentation. This product should be used under dermatological supervision, as irritation, redness, or allergic reactions may occur in people with sensitive skin.
• Chemical peels: Using fruit acids (e.g., glycolic acid) or trichloroacetic acid (TCA), the superficial layers of the skin are gently exfoliated, which can result in a smoother skin texture and the lightening of pigment spots. These procedures should be performed exclusively by experienced dermatologists, as improper application can lead to risks such as redness, inflammation, or scarring.
• Dermabrasion: During dermabrasion, the doctor uses a fine drill to remove the top layers of skin under local anesthesia. The formation of new tissue can help reduce age spots. However, the skin may remain red for several weeks, and there is a risk of scarring or uneven pigmentation.

Consult a dermatologist to find out which method is best for you.

Can age spots reappear after treatment?

Age spots may reappear after treatment, as they are often caused by UV radiation. To minimize the risk of recurrence, we recommend that you use a suitable sunscreen on your face, neck, and hands year-round. You should also avoid prolonged sunbathing to prevent not only age spots but also other types of skin damage.
