As light makeup has become a trend, more people are looking for clear, clean skin. However, pigmentation is not just one type; it can be a mix of melasma, freckles, moles, and blemishes. Let's look at how laser approaches differ depending on the type of pigmentation.
How Pigmentation Occurs
The main cause of pigmentation is exposure to UV light. This stimulates melanocytes, leading to an overproduction of melanin, which can result in melasma or freckles. In addition, there is also post-inflammatory pigmentation that remains after hormonal changes, acne, or skin inflammation. This includes cases where the skin darkens differently from the surrounding area after acne has subsided.
Why Lentigo is Tricky
Lentigo can be caused by UV light and aging, or it can be genetic. Since whitening products often show slow changes, many people seek diagnosis and treatment.
Pigmentation varies in type, color, and depth, so if the condition is not accurately identified at first, the treatment period may be prolonged.
A Method That Protects the Surface with Cooling
This laser uses CPTL technology with a contact cooling method to maintain a cooling temperature during the procedure, delivering energy while protecting the skin's surface. Energy is delivered through a handpiece with VSLS technology, and thanks to supercooling technology, it operates quickly while reducing the burden on the skin.
Consult about your pigmentation type
Three Modes and Precise Irradiation
- Choose from three modes: single, autoderm, and semi-auto derm, to target specific areas.
- Delivers energy to the pigmented area with a 532nm wavelength.
- Focuses on the desired area with position recognition and tracking guide technology.
Using smart glass, it can be performed clearly even on large areas or in various environments.
One-on-One Approach for Each Type
Melasma, freckles, moles, and blemishes require different methods depending on the lesion. A uniform approach may not suit your skin, so it is better to choose a place that provides a one-on-one pigmentation solution. The basic approach is to strengthen the dermis and reduce the recurrence of melanin.
If you are concerned about mixed pigmentation, please contact us via consultation chat. Suitability can be confirmed through a consultation with Dr. Choi Byeong-geun.
