How to Brighten Body Pigmentation with Laser Treatment at a Dermatology Clinic | Yonsei Star Dermatology Sinchon

If you've been bothered by dark marks on your armpits, elbows, or inner knees, we've compiled information on why body pigmentation occurs and how to improve it with methods like whitening medication and laser toning.

As the weather calls for lighter clothing, dark marks on the armpits, elbows, and inner knees tend to become more noticeable. Many people's first question is, "Can existing body pigmentation fade?" To answer directly, improvement has been reported when the causes are reduced and treatments targeting melanin are combined, though it's best to understand that it takes time.

Body Pigmentation: Why Does It Tend to Occur in Specific Areas?

Body pigmentation refers to the phenomenon where melanin accumulates excessively in certain areas, causing the skin tone to darken. The body has more areas prone to repeated friction and irritation than the face, making it easier for pigment to settle.

A prime example is the armpits. If you get a cut while shaving your armpits with an eyebrow razor, that irritation can lead to inflammation, and if repeated, the armpits may gradually darken.

Therefore, laser hair removal methods like GentleMax Pro Permanent Hair Removal can help reduce irritation compared to using a razor.

Common Traces of Irritation Seen in the Clinic

When continuous irritation is applied to the skin, that area becomes a cause of body pigmentation.

In the clinic, we often see patients who frequently scratch their necks due to itching, and in such cases, the skin in that area is often thickened and the pigmentation is also darker. It's also common for elbows to darken from frequent contact, or for pigmentation to appear on the back from sitting for long periods with a hard chair back touching the skin.

Once body pigmentation appears, it can take a surprisingly long time to fade naturally. Sometimes, pigmentation remains even after weight loss. In such cases, the help of whitening medication or laser treatment can assist in shortening the improvement period.

Common Causes of Pigmentation

If atopic dermatitis is severe, the affected area may darken. The correct term is atopic dermatitis, where inflammation on the skin can cause redness and itching, secondarily leading to pigmentation. Especially with atopic dermatitis, severe itching often leads to scratching, and the act of scratching itself becomes an irritation, further darkening the pigment.

Common everyday causes of body pigmentation are summarized as follows:

  • Scars and repeated irritation from shaving or hair removal
  • Areas habitually scratched or rubbed due to itching
  • Areas with frequent friction, such as elbows, knees, and back
  • Traces left after inflammatory conditions like atopic dermatitis
  • Skin where dryness persists, leading to repeated micro-inflammation

Cosmetics used at home tend to show effects more slowly compared to medication or laser treatments. If visiting a hospital is difficult, it's fine to start with cosmetics, but if there's little change after two or three months, it's advisable to consider more active methods like medication or laser. If you're curious about which method is right for you, you can use Chat consultation for body pigmentation treatment.

Misconceptions About Management, Here's the Truth

Some people expect lymphatic massage to improve blood flow and thus help. However, since the cause of armpit pigmentation is melanin, it's difficult to improve the cause with lymphatic massage alone. We do not recommend high expectations.

When skin becomes dry, micro-inflammation can occur in that area, and pigmentation tends to follow. Vaseline has moisturizing properties and may help prevent pigmentation caused by dryness to some extent.

What Treatment Options Are Available for Pigmentation?

image

Treatment is broadly divided into three categories. The first is cause treatment. Since the cause of pigment varies by condition, the underlying cause must be addressed. The second is to lighten existing pigment with whitening medication. This method has the advantage of being relatively inexpensive and simple, but it requires consistency, and there are cases where improper application of medication can worsen the condition due to secondary inflammation. Therefore, it's best to strictly follow the instructions for Epidermal Pigment Removal or those provided during consultation.

Laser ToningExpects changes in a relatively short periodCan be costly, requires multiple sessions

The third option, which is a bit more costly, is laser treatment combined with a Customized Whitening Solution. Laser treatment is useful for expecting improvement in a relatively short time. Of course, even with laser, it doesn't disappear in one go and takes time, but it is known to significantly shorten the period until pigmentation fades.

Commonly referred to as laser toning, this method involves multiple sessions with low output. Laser toning is widely used for body pigmentation as well.

How Many Laser Toning Sessions Are Needed?

The required number of sessions varies depending on the degree of pigmentation and individual constitution. More sessions are needed for severe pigmentation and higher desired improvement, while the duration is significantly shortened if you only want to lighten it by about half.

The core of body pigmentation is ultimately melanin. Approaching it by reducing the function and number of melanin cells has shown improvement even for old pigmentation, though individual differences may exist.

image

Some people worry that laser treatment might make the pigmented area even darker. Generally, laser treatment is performed by adjusting the output to be strong or weak depending on the situation. This is similar to how speeding in a car increases the risk of an accident, but maintaining an appropriate speed allows for relatively safe driving.

image

Laser toning uses relatively low energy, so you don't need to worry excessively.

image

Even old pigmentation is ultimately a state where the number and function of melanin cells have increased. Treatment that reduces their function and number can lead to improvement.

However, it's important to understand that the longer the pigmentation has been present, the longer the treatment period may be.

How to Reduce Pigmentation in Daily Life

Here are some management tips that are good to follow in daily life:

  • Reduce sun exposure; pigmentation tends to occur more easily with frequent UV exposure.
  • Do not scratch inflamed areas; soothe them instead.
  • Avoid habitually rubbing or scrubbing the skin.
  • Consistently moisturize to prevent dryness.

Paying attention to these points alone can significantly help reduce pigmentation.

Many body pigmentation conditions are inflammatory. Inflammation, simply put, refers to a state where the skin around an area is red, itchy, or stinging, and it's not uncommon for pigmentation to remain in that spot after such a process. Many people with similar concerns also pay attention to V-beam Facial Redness Treatment that lasts a long time or Bruise Treatment Without Damaging Surrounding Tissue that occurs after irritation.

If you're curious about the cause of your pigmentation or which treatment is right for you, feel free to ask through Consultation for pigmentation treatment tailored to my skin condition.

In Summary

During the summer, when more skin is exposed, dark marks on the body can be a small but bothersome source of stress. It's helpful to know that by reducing the irritating factors and, if necessary, combining whitening medication or laser treatment, improvement can be safely pursued at a dermatology clinic.
