Laser or peeling: what to choose to combat pigmentation

You look in the mirror and notice those dark spots again. After summer or hormonal changes, pigmentation appears on the face—a condition in which an excessive amount of melanin accumulates in certain areas of the skin. This is a common problem that often causes not only aesthetic discomfort but also anxiety about the overall condition of the skin. In search of an effective solution, many come across two popular procedures—laser pigmentation treatment and chemical peeling.

But how do you know which method is right for you? What risks and side effects should you consider? The MEDplus editorial team asked Uliana-Sofiia Savchenko, a cosmetologist with 10 years of experience in aesthetic medicine.

What is skin pigmentation, and why does it occur?

Skin pigmentation is a change in its natural color, which occurs due to excessive or uneven distribution of the pigment melanin. Melanin is responsible for the color of the skin, hair, and eyes.

Why does it occur?

• Due to exposure to the sun (ultraviolet light activates the production of melanin)
• Hormonal changes (for example, during pregnancy or when taking certain medications)
• After inflammation of the skin (post-inflammatory pigmentation)
• With age, when so-called age spots appear

Is pigmentation just an aesthetic problem or a sign of internal disorders?

Pigmentation is not just an aesthetic problem, but sometimes a sign of internal disorders.

On the one hand, age spots often appear due to external factors, such as excessive sun exposure, improper skin care, or age-related changes. In such cases, it is more of an aesthetic issue.

But on the other hand, the appearance of pigmentation may indicate malfunctions in the body:

• hormonal disorders (such as during pregnancy, thyroid disease, or when taking contraceptives)
• liver or gastrointestinal problems
• chronic inflammatory processes
• deficiency of specific vitamins.

What are the most common causes of pigmentation on the face?

The most common causes of pigmentation on the face:

1. Ultraviolet radiation is the leading cause. The sun stimulates the production of melanin, which causes dark spots on the skin.
2. Hormonal changes – during pregnancy, menopause, or when taking hormonal drugs (for example, contraceptives).
3. Post-inflammatory pigmentation – after acne, irritation, or skin injuries.
4. Age-related changes – with age, the cells that produce melanin function unevenly.
5. Genetic predisposition – in some people, the skin is naturally more prone to the formation of spots.
6. Improper skin care – aggressive procedures and a lack of SPF protection.

What causes pigmentation on the body – neck, back, arms?

Pigmentation on the body (neck, back, arms) can appear for various reasons:

1. The sun-exposed areas of the body (arms, neck) are often exposed to UV radiation without protection, which stimulates the formation of melanin.
2. Hormonal changes – can cause age spots not only on the face, but also on the body.
3. Age changes – over the years, so-called “age spots” appear on exposed areas of the skin.
4. Post-inflammatory pigmentation – after acne, insect bites, or irritations.
5. Chronic diseases – sometimes pigmentation on the neck or back is associated with metabolic disorders (for example, with insulin resistance).
6. Contact with chemicals or allergies – sometimes the skin reacts with pigmentation after irritation.

Which methods are considered the most effective in combating pigmentation today: laser or peeling?

Both approaches are effective, but the choice depends on the type of pigmentation, the depth of the spots, and the condition of the skin:

• Laser – destroys melanin point-wise, making it especially effective for treating deep or persistent pigmentation. Gives quick results, but requires competent selection of parameters and mandatory skin protection after the procedure.
• Chemical peels – gradually exfoliate the upper layers of the skin, even out the tone. Suitable for superficial pigmentation, after acne, for more sensitive skin.

In most cases, a combination of methods gives the best effect.

In what cases should you choose laser pigmentation removal?

Laser pigmentation removal is advisable in cases where pigment spots are deep, persistent, or have been present for a long time and do not respond to other methods. This procedure is especially effective for age-related, solar, or hormonal pigmentation when a more intense effect is required. The laser allows you to destroy melanin accumulations point by point, without injuring the surrounding skin, and provides a quick, noticeable result.

When is it better to choose a chemical peel?

A chemical peel is a suitable choice when pigmentation is superficial, has recently appeared, or is associated with post-acne, mild inflammation, or uneven skin tone. This method gently exfoliates the upper layer of the epidermis, lightening spots and stimulating skin renewal. Peeling is ideal for initiating the treatment of pigmentation or as a maintenance procedure between more intensive methods. It is often used for sensitive or thin skin.

Are these procedures suitable for treating pigmentation on the neck, back, arms, as well as face?

In my opinion, both laser and chemical peels are pretty suitable for removing pigmentation not only on the face, but also on the neck, back, or arms. It is essential to consider that the skin in these areas can be thicker and more sensitive, so the procedure should be performed by an experienced specialist who can select the appropriate type of peel or laser, taking into account the skin’s characteristics and the depth of pigmentation.

How safe are these procedures, and what are the possible side effects?

I believe that laser procedures and chemical peels are generally safe when performed by a qualified specialist and all recommendations are followed before and after the procedure. At the same time, it is essential to understand that these are still active interventions on the skin, so some side effects may occur.

After the laser treatment, temporary redness, swelling, peeling, or mild discomfort may occur – this is a normal reaction of the skin during the recovery process. Sometimes, especially if you do not follow sun protection, increased pigmentation or the appearance of new spots may occur.

Peeling, dryness, redness, and sometimes a slight burning sensation are also common after peeling. It is essential to prevent infection and protect the skin from ultraviolet rays to avoid exacerbating the situation.

Therefore, in my opinion, it is crucial to trust the procedures to professionals and carefully follow their recommendations, then the risks are minimal, and the effect is maximally positive.

Is it possible to completely get rid of pigmentation, or just reduce its manifestations?

In my opinion, it is difficult to get rid of pigmentation entirely, especially if it is a deep or persistent spot. Often, it is possible to significantly reduce its manifestations, make the skin color more even and light, but completely eradicating the problem is not always possible. It is essential to remember that pigmentation can reappear, particularly if you fail to follow proper care guidelines and do not protect yourself from the sun. So the main thing is regular prevention and maintenance of the results with the help of the proper procedures and cosmetics.

Is it possible to get rid of pigmentation at home?

If you want to fight pigmentation at home, you need to understand that this is not just easy care. Pigmentation is a change in skin color at a reasonably deep level, so to noticeably reduce it, quite aggressive products with active ingredients are often needed. Using them without the supervision of a specialist can be risky, because improper use can worsen the situation or cause irritation. Therefore, I believe that even home care should be based on the recommendations of a cosmetologist or dermatologist, who will help you choose safe and effective products. Without a professional approach, it is challenging to completely eliminate pigmentation on your own.

In general, home care can be effective if you choose the right products with the right active ingredients. But a lot depends on how old and deep the pigmentation is. Superficial pigmentation can be successfully treated at home, but deep or long-standing pigmentation usually requires more serious procedures. Therefore, to achieve good results, it is essential to understand your skin’s characteristics and not hesitate to seek advice from specialists.

What are the most common myths about skin pigmentation among patients?

1. Pigmentation appears only because of the sun.
   In fact, the sun is an important factor, but not the only reason. Hormones, inflammation, skin injuries, and even genetics can also have an impact.
2. Pigmentation can be quickly removed with creams.
   Creams help, but the effect is usually slow and not always complete, especially if the spots are deep.
3. The more cream you apply, the better.
   No, excessive use of active products can irritate or even worsen pigmentation.
4. Pigmentation is only a cosmetic problem.
   Sometimes it is a signal of internal disorders that should be checked.
5. Once pigmentation is removed, it will not return.
   Pigmentation can reappear, especially without proper sun protection.
6. Dark skin does not need sun protection because it does not tan.
   This is a myth. Ultraviolet radiation is harmful to all skin types and can cause pigmentation in everyone.
