Pigment spots: Why do they occur and how can you get rid of them?

Pigment spots (professionally known as hyperpigmentation) are among the most common aesthetic concerns affecting both women and men, regardless of age. Although they are harmless in most cases, they represent a visual concern for many people.

What is hyperpigmentation?

Hyperpigmentation occurs as a result of excessive production of melanin – the natural pigment that gives color to our skin, hair, and eyes. When certain cells start producing too much pigment in specific areas, darker patches appear on the surface of the skin.

Main types of pigment spots

Not every spot is the same. Determining their origin is key to proper treatment:

1. Sun spots (age spots): Caused by long-term exposure to UV radiation. They most commonly appear on the face, décolletage, and backs of the hands.
2. Melasma (chloasma): Often called the “pregnancy mask.” It develops as a result of hormonal changes (pregnancy, contraception) and mainly affects women.
3. Post-inflammatory hyperpigmentation: Dark spots that remain where acne, eczema, or skin damage has healed.

Most common causes

• UV radiation: The sun is the number one trigger. UV rays stimulate melanin production as a form of the skin’s natural defense.
• Genetics: A tendency to develop freckles and spots is partly hereditary.
• Hormonal influences: Estrogen and progesterone can increase sensitivity to the sun.
• Age: As the years go by, the number of melanocytes decreases, but the remaining ones enlarge and their distribution becomes less even.

How to remove pigment spots?

When choosing cosmetics, focus on ingredients that have been shown to suppress melanin production or accelerate cell renewal:

• Vitamin C: A powerful antioxidant that brightens the skin and blocks the enzyme tyrosinase (responsible for pigment production).
• Retinol (Vitamin A): Stimulates cell regeneration and helps “push” pigmented cells to the surface, where they naturally shed.
• Azelaic acid: Ideal for post-inflammatory hyperpigmentation after acne.
• Niacinamide: Prevents the transfer of pigment into skin cells.
• Chemical peel (AHA/BHA acids): Removes the top layer of dead skin cells and evens out skin tone.

Prevention is the cheapest option

Without consistent sun protection, any treatment is pointless. SPF 30 and above should be part of your routine 365 days a year, even when it is cloudy. UV rays penetrate clouds and glass as well. Prevention is absolutely essential in the case of pigment spots, because removing existing hyperpigmentation is a process that takes many months, while preventing it is possible with discipline.

Tip: Do not forget the neck, décolletage, and hands.

What can help with prevention?

1. Using SPF

The sun is the main trigger of pigmentation. Even if you have genetic predispositions or hormonal fluctuations, without UV radiation the pigment would not be activated to such an extent.

• Broad-spectrum protection: Use creams labeled SPF 30 and above, which protect against UVB (burns the skin) and UVA radiation (penetrates deeper and causes aging and pigmentation).

• Amount: You should apply approximately two fingers’ worth of cream to the face and neck. A small amount in makeup or day cream is rarely enough for full protection.

• Reapplication: If you are outdoors, the protective factor loses effectiveness after about 2 hours. In urban environments, SPF mists or powders that can be applied over makeup are helpful.

2. Antioxidants as an inner shield

UV radiation creates free radicals in the skin, which then stimulate melanocytes to overwork. Antioxidants neutralize this process.

• Vitamin C and E: Their combination in a morning serum under SPF cream increases the skin’s resistance to the sun.

• Ferulic acid: Stabilizes vitamins and increases their effectiveness in fighting oxidative stress.

• Diet: Consume foods rich in lycopene (tomatoes), beta-carotene, and polyphenols (green tea), which provide the skin with mild natural photoprotection from within.

3. Physical protection

Cosmetics are not all-powerful. The safest way to prevent pigmentation is a physical barrier:

• Hats and sunglasses: A wide-brimmed hat can reduce the impact of UV radiation on the face by up to 70%.

• Avoiding peak hours: Between 11:00 and 15:00, when the UV index is highest, try to stay in the shade.

• Protection behind glass: UVA rays also penetrate glass in a car or office. If you spend a lot of time by a window, SPF is a must even indoors.

When should you see a doctor?

Most spots are harmless, but if you notice that a spot changes shape, color, itches, or bleeds, it is essential to visit a dermatologist. These may be warning signs of skin conditions that require professional diagnosis.
