When scars don’t fade and become noticeably raised: Can laser scar treatment help? What types of scars can be treated?

Whether caused by an accident, surgery, or even acne, the resulting scars can significantly impact a person’s confidence. This is especially true when the scar is noticeably raised, hard, or discolored compared to the surrounding skin. Many people begin looking for treatments to help their skin return to being smooth and even, and one of the most popular technologies is laser scar treatment .

Understanding the Different Types of Scars

Before deciding on laser treatment, it is important to understand that there are several types of scars, and each responds differently to treatment. These include:

Hypertrophic Scars

These are raised scars that remain within the boundaries of the original wound. They typically result from surgical incisions or deep wounds where the skin produces excess collagen during the healing process.

Keloid Scars

These are raised scars that extend beyond the boundaries of the original wound and may be itchy or red. Genetics can be a contributing factor for some individuals.

Depressed Scars (Atrophic Scars)

Examples include acne scars or chickenpox scars. They occur when deeper layers of the skin are damaged and unable to produce enough replacement cells.

Discolored scars (Pigmented scar / Red scar)

These are scars that are darker or redder than normal skin. Even without an uneven texture, they remain noticeably visible.

How can laser scar treatment help?

Laser technology helps resurface the skin, stimulates new collagen production, and reduces scar discoloration to blend more closely with normal skin. The main benefits of laser scar treatment include:

Flattens raised scars for a smoother appearance
Fades scar discoloration (both red and dark spots)
Stimulates natural skin cell repair
Relieves itching or irritation around the scar area
Makes it easier to apply makeup or concealer.

Which types of scars are suitable for laser treatment?

Scars that respond well to laser treatment include:

Raised scars after the wound has fully healed (especially if they are not yet thick and hard).
Post-surgical or post-acne redness
Shallow to moderate depressed acne scars
Accident scars leaving dark spots or uneven skin texture

Which types of lasers can be used to treat scars?

The choice of laser depends on the type of scar and the individual’s skin condition. Examples of commonly used lasers include:

Pico Laser Helps effectively reduce pigmentation and dark spots. Suitable for dark-colored scars.
Fractional Laser (CO2 / Er:YAG) Helps resurface the skin and stimulate collagen production. Suitable for raised scars or acne scars.
Vascular Laser Suitable for redness or scars with prominent capillaries.
