Why Pico-Frectat Laser for Lentigo Removal Can Offer Positive Effects | [Yonsei Star Dermatology Sinchon]

Dark spots scattered across the face can be bothersome, often difficult to conceal even with makeup. As the weather warms and outings become more frequent, the desire for clear and bright skin grows. The first questions that come to mind are whether dark spots or patches are lentigines, and what approach should be taken.

Lentigines are pigmented lesions where melanin accumulates in the epidermis, appearing as distinct brown to dark brown spots. While they may seem light on the surface and appear easy to remove, they are tricky because they can easily reappear if the underlying skin condition, invisible to the eye, is not also addressed.

For this reason, many people stop treatment midway and opt to cover them with makeup. However, as pigment can darken and its borders become more distinct over time, relying solely on temporary concealment may have its limitations.

If you are concerned about dark spots on your face, understanding the nuances of pigment treatments like Epidermal Pigment Removal for similar blemishes, age spots, and freckles can make it much easier.

Among the devices used for pigment treatment, the RePott Laser has recently garnered attention. It utilizes a 532nm wavelength, which has a high absorption rate for melanin pigment. While possessing relatively strong power, it is designed to reduce post-treatment pain or discomfort through VSLS and contact cooling technology.

How do these two emphasized technologies relate to lentigo treatment? Beneath the lentigines we see on the surface, many blood vessels are located. It is reported that if only the intensity is increased when treating pigment, the blood vessels can be stimulated, potentially leading to additional post-inflammatory hyperpigmentation.

In the case of Reepot, the aforementioned technology is used to temporarily cool and constrict blood vessels before proceeding. This state can help minimize unnecessary damage to blood vessels and skin. Additionally, the device's built-in AI technology recognizes lesions by coordinates, allowing for relatively precise targeting, selectively aiming at pigment while protecting the blood vessels beneath the skin.

After laser treatment, the treated area of the brown lesion appears white. This phenomenon occurs when strong output is applied, causing the epidermis and dermis to separate, and air enters between them, making it appear white. This can be understood as part of the recovery process that leads to scab formation.

How you manage this period can affect your satisfaction with the results. In the clinic, we often see that the progress is much more stable when recovery care is diligently followed.

• After the procedure, use a hydrocolloid dressing like Duoderm to manage exudate and protect against external irritation.
• It is generally beneficial for recovery to leave the attached dressing on for about 2 weeks without forcibly removing it.
• If a scab forms, do not pick at it; let it fall off naturally.
• During the recovery period, be more diligent than usual with sun protection.
• If exudate or redness persists differently than usual, consult with medical staff.

If you have questions about Reepot Laser care methods or recovery time, you can easily inquire through chat consultation regarding Reepot Laser.

Pigmentary disorders on the skin are diverse, but they commonly present the challenge of frequent recurrence, making treatment difficult. Also, due to the nature of laser treatment, multiple sessions may be required, which can feel cumbersome. However, it is positively reported that there are increasing numbers of devices, like the Reepot Laser, that allow for relatively convenient and precise management through increasingly advanced technology.

Beyond lentigines, there are many cases where similar-looking pigmentations or Laser Lesion Removal for moles, syringomas, and warts can be confusing. Even if they look similar, the approach may differ, so accurate confirmation by a professional is prioritized over self-diagnosis.

The above categories are a broad framework for understanding, and even for the same lentigo, the approach may vary depending on depth and distribution. Therefore, it is important to undergo the process at a place where you can thoroughly confirm what is necessary for you before the procedure.

If you have been struggling with pigment concerns for a long time, you might feel overwhelmed about what to check first. Looking into the type and depth of the lesion, the feasibility of recovery care, and guidance on repeated procedures can help reduce the burden. When pigmentation appears to overlap with other scars or other treatments like Customized Whitening Solution, even more careful verification is needed.

We hope you take a step closer to clear and clean skin that matches the bright weather of the upcoming spring. If you are curious whether lentigines or the Reepot Laser are right for you, we recommend a light consultation before making a decision.
