Can pixel laser remove hypertrophic scars?

Generally, if the hypertrophic scar is light in color and small in size, fractional laser treatment can usually remove it. However, for darker and larger hypertrophic scars, fractional laser may not completely eliminate the scar. The details are as follows:

Fractional laser is a non-ablative laser therapy technique that delivers tiny laser beams onto the skin surface to stimulate collagen regeneration and promote skin repair. For hypertrophic scars that are light-colored and relatively small, fractional laser is typically effective in removing the scar tissue and can significantly smooth the scar, improving its appearance.

For darker and more extensive hypertrophic scars, fractional laser alone may not achieve complete removal and could potentially worsen the scarring. In such cases, combined approaches—such as laser abrasion, fractional laser treatment together with surgical excision—may be considered under a physician's guidance to achieve better results.

If you intend to treat or remove a hypertrophic scar, it is recommended to visit a reputable medical facility and undergo treatment under the supervision of a qualified doctor to avoid unnecessary physical harm. Additionally, maintaining a healthy diet and avoiding spicy or irritating foods—such as Sichuan pepper, chili peppers, and ginger—can help support skin recovery.
