How does laser treatment for sun spots work?
Sun spots, medically known as solar lentigines or senile lentigines, are accumulations of melanin in the skin caused by chronic exposure to ultraviolet radiation. Laser treatment offers a precise solution for these hyperpigmentations. Light systems, such as the Q-Switched laser and Intense Pulsed Light (IPL), emit specific light energy that is selectively absorbed by the melanin present in the spots.
This absorption of energy causes rapid heating and fragmentation of the pigment into tiny particles. These particles are then recognized and eliminated by macrophages, cells responsible for the body's cleansing, or they move to the skin's surface to shed naturally. The process is selective, minimizing damage to surrounding tissue.
Types of laser and their application
At Santé Clínica Estética, we use advanced laser technologies to effectively and safely address sun spots. The choice of laser type depends on the nature of the spot, the patient's skin type, and the depth of the pigment.
Q-Switched Laser for Pigmentation
The Q-Switched laser is especially effective for solar lentigines and other hyperpigmentations. It emits very short, intense energy pulses, measured in nanoseconds, which are absorbed by melanin. This rapid absorption fragments the pigment into tiny particles, facilitating their elimination by the body's lymphatic system.
This laser allows for specific treatment of pigmentation, minimizing the risk of damaging surrounding tissue. It is a well-tolerated procedure, with a sensation similar to small "taps" on the skin. The number of sessions required will be determined during the medical consultation, as it varies depending on the spot and individual response.
Intense Pulsed Light (IPL)
Although not strictly a laser, Intense Pulsed Light (IPL) is a widely used technology for photorejuvenation and the treatment of diffuse sun spots. Unlike laser, IPL emits a broader spectrum of light that can be filtered to target specific chromophores such as melanin and hemoglobin. This allows for the simultaneous treatment of pigmented spots and small vascular lesions.
IPL is suitable for treating larger areas with sun damage, improving overall skin tone and texture. The sensation during treatment is one of intense heat and flashes of light. The number of sessions required will be established in the medical consultation, with an interval of 3 to 4 weeks between each, depending on the patient's evolution.
The process of sun spot removal
Laser treatment for sun spots follows a medical protocol to ensure safety and efficacy. The general process is detailed below:

B --> C{Selection of Appropriate Laser (Q-Switched or IPL)}
C --> D[Skin Preparation and Eye Protection]
D --> E[Laser Application to Spots]
E --> F[Temporary Darkening of Spots]
F --> G[Formation of Small Superficial Scabs]
G --> H[Natural Shedding of Scabs (5-10 days)]
H --> I[Clearer and More Uniform Skin]
I --> J[Post-Treatment Care and Strict Sun Protection]
J --> K[Results Evaluation and Additional Sessions if Necessary]
After laser application, a temporary darkening of the treated spots is common. This indicates that the pigment has absorbed the energy and is beginning its fragmentation process. In the following days, the spots may form a small superficial scab that will shed naturally. It is essential not to manipulate these scabs to avoid scarring or post-inflammatory hyperpigmentation.
Key points
- Q-Switched laser and IPL work by fragmenting melanin in sun spots.
- Light energy is selectively absorbed by the pigment, without damaging surrounding skin.
- The body naturally eliminates fragmented pigment particles.
- A prior medical evaluation is crucial to determine the most suitable treatment.
- Post-treatment care is required, especially strict sun protection.

Prices and expected results
The cost of laser treatment for sun spots varies depending on the type of laser used, the extent of the area to be treated, and the number of sessions required. At Santé Clínica Estética, Q-Switched laser treatment for pigmentation costs €300 per session. For IPL treatments, the price is also €300 per session. These prices are per session, and it is important to note that individual results may vary.
| Treatment | Price per Session | Observable Results |
|---|---|---|
| Q-Switched Laser (pigmentation) | 300€ | Visible reduction of solar lentigines. |
| IPL (diffuse pigmentation) | 300€ | Improvement in tone uniformity and spot reduction. |
Final results are generally evaluated a few weeks after the last session, once the pigment elimination process has concluded. It is fundamental to understand that exact results cannot be promised and that each skin's response to treatment is unique. Strict sun protection is mandatory before and after treatment to prevent the reappearance of spots and optimize results.
Frequently asked questions
Is laser treatment for sun spots painful?
Most patients describe the sensation as a slight prick or an elastic "tap," similar to a rubber band snapping against the skin. It is a tolerable and short-lived discomfort. Generally, anesthesia is not required, although a topical anesthetic cream can be applied if the patient requests it for greater comfort.
How long does recovery take?
Recovery is minimal. Immediately after treatment, spots may darken and the area may show slight redness or swelling, which usually disappears within a few hours. The fine scabs that form over the spots usually fall off in 5 to 10 days, revealing clearer skin. It is essential to avoid direct sun exposure and use broad-spectrum sunscreen (SPF 50+) for at least one month after treatment.
Will sun spots reappear after laser treatment?
Laser removes existing spots, but it does not prevent the formation of new spots if the skin continues to be exposed to the sun without protection. Prevention is key: daily use of sunscreen, hats, and avoiding peak sun hours are essential to maintain long-term results. A healthy lifestyle and an appropriate skincare routine also contribute to prevention.
Can I wear makeup after the treatment?
Generally, makeup can be applied the day after treatment, once the skin does not show significant redness or irritation. It is advisable to use mineral makeup or gentle products to avoid any irritation. Make sure the makeup does not clog pores and is gently removed at the end of the day.
Is laser effective for all types of pigmented spots?
Q-Switched laser and IPL are very effective for solar lentigines and some forms of melasma. However, not all pigmented spots are the same. Birthmarks, moles (nevi), or certain skin lesions require a different medical evaluation and, in some cases, are not suitable for laser treatment. A prior medical consultation is essential for an accurate diagnosis and to determine the suitability of the treatment.
