Pigmentation spots: causes and solutions

Pigment spots on the face result from localized overproduction of melanin, the pigment that colors the skin. Their main causes are sun exposure, hormones, inflammation (after a pimple), and aging. Two approaches exist to address their appearance. In aesthetic medicine, in-office procedures like laser or pulsed light target the pigment. On the cosmetic side, active ingredients like vitamin C, gentle exfoliating acids, and good sun protection help reduce their appearance and even out skin tone.

These marks, also known as brown spots, are areas of skin darker than the rest of the complexion. Very common, they mainly appear with age or after repeated sun exposure. Understanding their origin helps choose the right approach, from daily care to aesthetic procedures.

What is a pigment spot?

Skin color primarily depends on melanin, a pigment produced by melanocytes. When these cells produce too much locally, or when pigments are unevenly distributed, a darker area appears: this is hyperpigmentation. Most often harmless, it is primarily an aesthetic concern, creating an uneven complexion.

Origins of pigment spots

Sun exposure

This is the number one cause. Under the effect of UV rays, the skin produces more melanin to defend itself; over time, this production concentrates and forms lasting marks on the face, décolleté, back of the hands, and arms.

Hormones

Certain hormonal variations (pregnancy, contraception) promote melasma, or the mask of pregnancy; the sun accentuates the phenomenon.

Inflammation

After a pimple, lesion, or irritation, the skin may retain a mark: this is post-inflammatory hyperpigmentation, common after acne and sometimes associated with small scars.

Aging

With age, melanin regulation becomes less regular, which promotes age spots, often combined with the cumulative effects of the sun.

Marks that are not alike

Not all have the same nature, and this guides the management:

• Lentigines (sun or age spots): well-defined, on the most exposed areas.
• Melasma: more diffuse, of hormonal origin, sensitive to the sun.
• Post-inflammatory marks: pigments left by a pimple.

A dermatologist clarifies the nature of each, as the same technique is not suitable for all.

Laser and dermatological procedures

Important context: laser and pulsed light are external aesthetic procedures performed in-office by a doctor. They are not for home care. Here's how professionals describe them, for informational purposes.

Pigmentary laser

It emits light absorbed by the pigment. The goal described by practitioners is to fragment excess melanin so that the body gradually eliminates it. Q-switched lasers are often cited for lentigines; the number of sessions depends on the mark and skin type.

Pulsed light (IPL)

This is not really a laser: the technique diffuses light of several wavelengths and aims to even out superficial areas. Again, several sessions are often necessary, under medical supervision.

Procedure and aftermath

A session lasts a few minutes depending on the area. Typical aftermath includes temporary redness, sometimes fine scabs. Side effects exist (sensitivity, transient color change), which the practitioner explains before indicating the procedure. Strict sun avoidance follows each session.

Cost and contact person

The price depends on the area, the number of sessions, and the clinic: prices vary greatly and are given during an assessment. The contact person remains the dermatologist, who evaluates the mark before any decision and can, in some cases, prescribe a lightening cream.

Cosmetics or dermatology: how to choose?

The two approaches do not have the same goal and often complement each other.

In practice, cosmetic care supports the complexion daily and helps prevent new marks; in-office procedures are considered with a dermatologist for well-identified cases.

Daily cosmetic routine

Remember: no cosmetic product can make a spot disappear. However, certain active ingredients help reduce their appearance and visibly even out skin tone, with regular use.

Vitamin C

This antioxidant active ingredient is valued for radiance. It helps reduce the appearance of marks and restore luminosity, while protecting against oxidative stress. A vitamin C serum is applied in the morning, under day cream.

Gentle exfoliation

Gentle chemical exfoliation, based on AHA acids, supports surface renewal and refines skin texture: the complexion appears more radiant. It should be used in moderation (1 to 2 times a week) and always with sunscreen the next day.

Sun protection

This is the key step. Without it, marks tend to worsen and reappear. Daily sun protection helps preserve the results of the routine, as well as those of any potential treatment.

Building a coherent routine

A radiance routine is based on three pillars: a vitamin C serum, regular gentle exfoliation, and daily sun protection. Patience is key: the effects on skin tone are appreciated over several weeks.

Frequently Asked Questions

Can spots be removed with cosmetics?

No. Cosmetic care helps reduce their appearance and visibly even out skin tone. For established marks, a dermatologist can offer suitable solutions.

Does laser really remove facial spots?

It is a medical procedure that aims to target pigment; results vary depending on the case and often require several sessions. Only a doctor can determine if it is indicated for you.

How many sessions should I expect?

This depends on the mark, the area, and the skin type. The number of sessions and prices are specified by the clinic during an assessment.

Is vitamin C effective?

It is known to help reduce the appearance of marks and restore radiance, as part of a routine combined with sun protection.

When to consult?

If a mark rapidly changes in appearance, color, size, or shape, consult a dermatologist as a precaution.

In summary

Pigment spots result from excess melanin, favored by sun exposure, hormones, inflammation, and age. Two complementary approaches exist: dermatological procedures (laser, pulsed light), performed in-office, and home care. On the cosmetic side, vitamin C, gentle exfoliation, and daily sun protection help reduce their appearance and even out skin tone, with regularity.
