A step-by-step guide to treatment options for post-burn pigmentation, by type | [Yonsei Star Dermatology Sinchon]

It's not uncommon for people to visit Yonsei Star Dermatology Sinchon because a red area from a burn has gradually darkened to brown as it healed, or conversely, turned whiter than the surrounding skin. The first question we hear in the consultation room is always the same: "Will this mark disappear on its own, or do I need treatment?" To answer directly, the response varies depending on the depth and form of the remaining pigment.

In this article, we'll systematically explain what post-burn pigmentation looks like, why it occurs, and what treatment directions can be taken.

Pigment changes remaining after a burn heals largely fall into two categories: hyperpigmentation, where the color darkens, and hypopigmentation, where the color lightens. Even with the same burn, it can appear differently depending on the individual and the area, so distinguishing which type it is at the initial examination is the starting point for treatment.

Post-burn pigmentation is surprisingly common. It can occur from a curling iron touching the forehead, lead to low-temperature burns from prolonged exposure to low heat, or leave marks after sunburn in the summer.

Burns cause injury to the skin. Various inflammatory substances are secreted to heal the wound, and some of these stimulate melanocytes. If stimulated cells produce excessive melanin, the area turns dark, resulting in hyperpigmentation. Conversely, if the melanin-producing melanocytes are completely destroyed by the burn, hypopigmentation remains in that area.

There isn't just one approach to hyperpigmentation. It's natural to choose methods based on the depth and intensity of the pigment.

The simplest starting point is to try using whitening creams. However, ointments tend to react slower than other treatments, and it takes a long time to see sufficient changes. In particular, they often show little to no reaction to pigment located in deeper layers.

Therefore, laser treatment targeting epidermal pigment, toning, or fractional lasers may also be used. Laser treatment for post-burn pigmentation is usually performed 5-10 times at intervals of 2-4 weeks, and it is reported that the dark pigment gradually lightens with repeated sessions. However, the speed and degree of response may vary individually.

In some cases, customized whitening care to refine overall skin tone is considered, but it is also advisable to first check the depth of the pigment and skin condition before deciding on a direction.

There are several methods that can be attempted for hypopigmentation, where the color has lightened. If melanocytes are completely absent during the laser treatment process, the pigment will not return.

However, there are cases where melanocytes are not completely gone but merely dormant. Melanin pigment is located deep around hair follicles, and if dormant cells are awakened by laser stimulation, they can produce color again, creating an opportunity to address burn scars and pigment changes together.

The second method is topical medication. This approach has the limitation of being slow to show effects. If, despite these attempts, melanocytes completely lose their function and hypopigmentation remains, methods such as epidermal grafting, which involves transplanting melanocytes from another area, may be considered.

If the pigment is very light, it may fade over time. It's easy to understand if you think of how skin tanned dark by the sun in summer becomes noticeably lighter by winter.

However, if the pigment is a bit deep and intense, it often remains unchanged over time. In such cases, we recommend actively seeking treatment rather than neglecting it.

There are many things you can do to take care of yourself. It's good to pay attention to the following in your daily life:

• Avoid strong sunlight on the burn area and newly healed skin, and pay attention to UV protection.
• Do not pick or scratch scabs or dead skin with your hands.
• Do not arbitrarily use whitening creams for long periods based on self-diagnosis.
• If you notice changes where pigment darkens or lightens, seek early medical attention.
• The depth and form of pigment are difficult to determine with the naked eye, so confirm with a dermatologist.

Since the forms vary from mild pigmentation to hypopigmentation and hyperpigmentation, it is most important to first confirm with a dermatologist what type of pigmentation you have and how deep it is, then establish the appropriate treatment direction.
