Dark pigment spots on the face can be bothersome every time you look in the mirror, but it's often hard to know where to start. The first questions that usually come to mind are, "Is this melasma, lentigo, or freckles, and can it be cleanly removed with a laser?" To get straight to the point, lentigo with clear borders has limitations with toning alone, and a laser that precisely targets the lesion is reported to be more suitable.
Clear and clean skin is something many people desire. Even if your skin tone is on the darker side, fewer blemishes give a healthy and neat impression. Conversely, if your skin is naturally light but blemishes increase, it can easily change to a dull and aged appearance.
Why is lentigo perceived as particularly difficult to remove?
It's a well-known fact that once pigment problems like melasma, freckles, blemishes, lentigo, or seborrheic keratosis appear on the face, it takes considerable time and effort to remove them. Among these, many people feel that lentigo is particularly stubborn.
Those who wish to remove facial lentigo often find it challenging to manage. Frequent recurrence is one reason, but when we see patients with lentigo in the clinic, they often have melanin widely spread across their skin. In such cases, other pigment disorders like melasma, freckles, and various blemishes often appear together, which can make lentigo removal feel even more difficult.
How do melasma and lentigo differ?
Facial lentigo varies in shape but appears with distinct borders, unlike melasma. It can occur in both shallow and deep layers of the skin, making it often difficult to accurately distinguish whether it's lentigo, melasma, or freckles just by looking at the surface.
| Classification | Border | Distribution | Common Location |
|---|---|---|---|
| Lentigo | Relatively clear | Scattered as spots | Exposed areas like cheekbones, forehead |
| Melasma | Blurry, spreading | Broad, symmetrical | Both cheeks, forehead |
| Freckle | Small and uniform | Multiple spots | Nose, cheeks |
Because such distinctions are difficult, not a few people try to solve pigment problems all at once with devices like laser toning. However, achieving satisfactory results for lentigo with toning alone often presents several difficulties.
Why are there limitations with toning alone?
First, the significantly increased number of sessions is a major barrier. The pigment forming lentigo is very stubborn and difficult to destroy, and the intensity of toning often falls short of expectations.
This can naturally lead to more sessions and gradually increasing intensity. If such treatments continue, concerns about skin irritation are inevitable. While melanin pigment needs to be reduced, conversely, if pigment is excessively destroyed, it can lead to hypopigmentation, where the skin turns whiter than normal.
While reducing pigment, if melanin is excessively stimulated all at once, hypopigmentation, once formed, is difficult to reverse. Therefore, it is important to carefully design laser intensity and frequency according to the lesion.
If you feel that lentigo pigment is not fading well, it might be helpful to check if you also have Epidermal Pigment Removal concerns, which are in the same pigment category. For more accurate status confirmation, you can use Inquire about pigment laser selection via chat.
Reepot Laser, suitable for lentigo
This raises the question of which laser to choose for facial lentigo removal. Until now, toning has been most frequently mentioned for pigment problems, leading many to believe that this one device could solve all issues. Recently, RePott Laser, which is reported to show good effects in treating lentigo, has been gaining attention.
The advantage of Reepot Laser lies in its precision.
- Treatment is performed only on the problematic pigment lesion, minimizing damage to healthy skin.
- It is equipped with a cooling system, allowing for strong energy delivery with reportedly less pain during the procedure.
- In cases of epidermal pigment, removal in 1-2 sessions has been reported.
- For complex cases involving deep dermal pigment, a phased approach is taken in combination with other pigment lasers.
If the lentigo is confined to the epidermis, it can often be resolved in relatively few sessions. If multiple pigment problems, including lentigo, are complexly present deep in the dermis, an approach combining Epidermal Pigment Removal or Pico-series pigment lasers suitable for the lesion may be applied.
Phased approach for complex pigment
At Yonsei Star Dermatology Sinchon, in addition to the Reepot Laser used for facial lentigo removal, various other devices, including Customized Whitening Solution, can be used together, allowing for a phased approach tailored to the lesion's condition. Since the combination varies depending on whether the pigment is shallow or deep, and whether it's a single or complex lesion, prior status confirmation is important.
Before and after treatment, remember these points
Pigment disorders, from melasma to freckles, seborrheic keratosis, and facial lentigo, have long been considered difficult to resolve all at once. However, with Reepot Laser, which can show changes even with fewer sessions, and advanced pigment lasers, an approach is possible, so there's no need to give up prematurely on long-standing pigment. Remembering the following points can be helpful:
- Treatment effectiveness and number of sessions may vary individually depending on the depth and type of pigment.
- Consistent UV protection after treatment is important to reduce recurrence and hyperpigmentation.
- If scabs or pigment changes appear, do not arbitrarily stimulate them; observe the healing process.
- If other pigment disorders are present, proceed in stages rather than overdoing it all at once.
Even if the pigment has been present for a long time, feel free to check your condition.
