When you're looking into lasers because you're concerned about sunspots or pigmentation, similar questions come up repeatedly. Sunspots, which vary in darkness, are not easy to cover with makeup. We've compiled frequently asked questions, along with explanations of the principles behind them.
Why do sunspots appear?
Sunspots often result from sun exposure or aging, and can also be hereditary. Their darkness varies greatly depending on the individual and skin type. If applying brightening products shows slow changes, many people seek a diagnosis and approach treatment.
Once pigmentation starts to bother you, it can make your appearance seem more prominent than it actually is, so it's important to first identify the type of pigmentation.
Is normal skin not damaged?
This laser focuses on pigmented areas with a 532nm wavelength.
- It maintains the set cooling temperature using a contact cooling method and vascular supercooling technology.
- It helps break down and expel pigmentation while protecting the skin's surface.
- It reduces discomfort during the procedure with a smooth sapphire tip.
Does it target only the exact area?
It uses position recognition and tracking guide technology. An external medical camera collects lesion data in real-time, then targets, supercools, recognizes the image, and outputs the laser. Smart glasses can be used to ensure clear treatment in various environments.
Consult about your pigmentation type
What types of pigmentation can be treated?
It can address not only sunspots but also common yet difficult-to-manage pigmentation such as melasma and seborrheic keratosis. However, the method varies depending on the pigmented lesion, so during your first visit, it's necessary to assess your skin type and identify the specific pigmentation issue.
How do I choose a clinic?
Even with the same laser, the approach to treating pigmentation differs based on the diagnosis. Instead of a uniform approach, it's better to choose a place that offers a one-on-one solution aimed at strengthening the dermis and reducing melanin recurrence. Also, check if they provide guidance on post-procedure care, such as sun protection.
If you're starting to be concerned about sunspots or pigmentation, please inquire via chat consultation. Suitability can be confirmed through a consultation with Dr. Choi Byeong-geun.
