The key to treating lentigo is not weak treatments multiple times, but one precise treatment. Many people are meticulous about brand and quality when buying a bag, but often only consider cost-effectiveness for their precious facial skin. In this article, we will gradually explain the criteria for lentigo treatment without regret.
Is it gentle if it's weak and repeated many times?
Many people think that receiving weak laser treatments multiple times will be gentler on the skin. This idea may not be correct for lentigo.
- Lentigo often has deep roots and can be accompanied by tissue degeneration in the surrounding area.
- It is not easy to remove even with insufficient energy applied multiple times.
- Repeated, meaningless stimulation can compromise the skin barrier and make it sensitive.
In some cases, the lentigo area may even darken.
Side effects caused by repeated treatments
Too frequent treatments can lead to rebound hyperpigmentation or hypopigmentation. A dermatology journal article warns that excessive repetition of laser toning can damage melanocytes, causing the skin to become patchy and white.
The reason why lentigo darkens or difficult-to-treat white spots appear when chasing cost-effectiveness is precisely due to repeated treatments.
Strong energy once, but safely
The principle for lentigo is to treat the root with strong energy in one go. Naturally, the question arises whether this will damage the skin. The answer lies in research.
According to a paper published by Yonsei Star Dermatology in a European dermatology journal, even when using strong energy, cooling devices can protect the skin surface, reducing side effects and allowing for safe and effective treatment.
- At the moment the laser is fired, the skin surface is protected by a cool shield.
- During this time, strong energy is delivered to the root of the lentigo.
- The goal is a single treatment while minimizing skin damage.
The principle implemented by RePott Laser
The device that implements this principle is the RePott Laser. It aims for precise treatment while minimizing damage by protecting the surface with cooling and delivering energy deep inside.
You can quickly return to daily life
One of the advantages of RePott Laser is that daily life is possible immediately after the procedure.
- A Duoderm regenerative tape is applied to the treated area to protect the skin.
- The tape carefully covers the area, minimizing interference with washing, makeup, and going to work.
- This is compared to receiving toning all year round and clearing time every week.
It is explained that managing with a single tape for about two weeks is a more efficient and reasonable choice.
Choose treatment, not experimentation
Skin repays you when it meets good equipment and accurate diagnosis. If you are upset by lentigo in the mirror, now is the time to choose proper treatment as your standard, rather than repeated experimentation.
Results may vary by individual, and accurate diagnosis and treatment are determined after consultation.
