We will also answer some questions about scabs, so please refer to this article if you are concerned about the process after laser stain removal.
What is a spot removal laser?

*Image is for reference only.
A spot removal laser reacts to melanin pigments to improve melasma and spots. First, we will introduce the types of spot removal lasers and the process after treatment.
Types of Blemish Removal Lasers
There are several types of spot removal lasers, depending on the characteristics of the treatment and the expected effects. The picolaser, which irradiates in picoseconds (trillionths of a second), can target and destroy only melanin pigments, so it requires fewer irradiations. Laser toning uses a low power output to gradually fade spots, resulting in little or no downtime, but it requires multiple sessions. In addition, Q-switched ruby lasers and fractional lasers can also be used.
In YAYOI CLINIC,Cerec V, TriBeam Premium (Q-switched Nd:YAG laser), Q-switched ruby laser, etc.There are two types of machine treatments for spots. The choice depends on the type of blemish you wish to treat and the desired approach.
Progress of laser spot removal
The condition of the skin after a blemish removal laser treatment depends on the type of device used. Let's take a look at the progress of a typical spot removal laser.
[Skin condition after laser blemish removal.
- Scabbing lasts about 1 week.
- After treatment, use a protective seal to protect the affected area
- The scab will naturally peel off and new skin will form in about 1 week to 10 days after treatment.
- Post-inflammatory hyperpigmentation may be seen in the area where the spots were located from about 2 weeks to 1 month after the treatment.
- If post-inflammatory hyperpigmentation is observed, it will settle down in as little as 3 months or as long as 6 months to 1 year.
Most cases of post-inflammatory hyperpigmentation will disappear with time, but in some cases, aftercare may be provided through the use of topical medications.
What causes no scabbing after laser spot removal?

In general, Q-switched ruby lasers, pico lasers, limelight, and Q-switched YAG lasers are treatments that often form scabs after treatment. If a scab does not form over the treated area despite the use of a blemish removal laser that is supposed to scab over, let's look at what causes this.
It's not like a scab that forms after an injury.
When you hear the word "scab," you may imagine a thick, dry shape like those that form after an injury. However, scabs after laser blemish removal look somewhat different from normal scabs, such as fine dots, a thin brown film, or a darker color. This difference from the imagined scab may cause the patient to mistakenly believe that no scab was formed.
When the irradiation output is too weak
Even if a treatment that causes scabbing has been performed, scabbing may not occur if the spot-removing laser is performed with a device that has a low irradiation power. In this case, the power of the laser on the blemish is weak.Melanin pigment is not destroyed and spots are not improved。
When the irradiation output is too strong
Excessive power may also cause scabs to fail to form. In particular, when irradiating dark spots or freckles, the laser is likely to overreact, resulting in a failure to scab over the spots. This is due to the fact that the blemish tissue disperses and disappears as soon as the laser is applied. The blemish tissue is destroyed, though, so the blemish itself does not remain,May cause significant skin damage and hyperpigmentation. Some equipment may be too powerful to treat at the lowest output, so choose a clinic that uses equipment that can handle a wide range of outputs.
If the pigment is only in the deep layer
Even if the stain you wish to treat is in a deeper layer, it may not scab over after the stain removal laser. Blemishes that do not scab easily include nevus ota, ectopic mongolian spots, nevus ampullus, ADM (acquired dermal melanocytosis), and tattoos. If laser treatment is performed on these spots, there is no need to worry because they do not scab over. If you are unsure of the type of blemish, check with your doctor.
What to do if a spot does not scab over after laser treatment for blemish removal
Q-switched ruby lasers and pico lasers are treatments that tend to form scabs when irradiated at the correct power. However, even in the unlikely event that a scab does not form, it is usually not a failure. This is because spots will gradually improve over several months to a year after irradiation,We'll see how it goes for a while.。
However, some doctors irradiate at a lower power considering the pain and pigmentation after the procedure. In this case, it is necessary to ask the doctor to change the output because it may not form a scab and the expected result may not be obtained. Please consult with the clinic first.
