Age Spots: What Causes Them and How to Reduce Them?

Over time, the skin evolves and reveals the marks of its history. Among the visible signs of skin ageing, age spots are one of the most common concerns. Often found on the face, neck, décolleté or hands, these brown spots alter the skin’s appearance and can dull its natural radiance. What causes them to appear, and above all, how can they be reduced over time with targeted skincare and a tailored routine?

Brown spots or age spots?

Age spots, also known as brown spots or lentigines, are areas of cutaneous hyperpigmentation. They are characterised by a darker coloration of the skin, linked to an overproduction of melanin, the natural pigment responsible for skin colour. Unlike spots related to acne or scarring, they develop gradually with age and are primarily associated with repeated sun exposure over the years.

These spots are harmless to health, but they are often perceived as a sign of premature ageing. They can affect all skin types and appear on both the face and the body, particularly on areas most exposed to the sun.

The different causes of age spots

The main cause of age spots is sun exposure. Solar radiation, and more specifically UV rays, stimulates melanin production as a protective mechanism for the skin. With age, this defence process becomes less even: melanin accumulates irregularly, leading to the formation of visible brown spots.

Natural skin ageing also plays a key role. Over the years, cell renewal slows down, the skin becomes thinner and more vulnerable to external aggressors. This fragility promotes hyperpigmentation and makes spots more persistent.

Other factors can intensify the phenomenon:

• intense or insufficiently protected sun exposure,
• lack of daily sun protection,
• oxidative stress,
• certain deficiencies, particularly in vitamins,
• hormonal imbalances.

Together, these factors explain why age spots often appear after many years of cumulative sun exposure.

How can their appearance be prevented?

Prevention is a key step in limiting the development of new age spots. The first essential reflex is to adopt suitable sun protection all year round. Daily application of a skincare product with SPF helps protect the skin from the sun’s rays responsible for hyperpigmentation, even on cloudy days.

In addition, a consistent skincare routine helps strengthen the skin barrier and preserve its radiance. Products rich in antioxidant ingredients support the fight against skin ageing, help prevent the appearance of wrinkles and limit pigment irregularities. An appropriate skincare product used morning and evening promotes a more even complexion and slows visible signs of ageing.

How can brown spots or age spots be reduced on the skin?

To visibly and lastingly reduce established age spots, it is essential to adopt an expert skincare routine capable of addressing hyperpigmentation, cutaneous senescence and overall skin quality.
