Do Scars Come Back After Laser Treatment? A Complete Analysis


Laser treatments have become increasingly popular for addressing various types of scars, including the following:

  • Acne scars
  • Surgical scars
  • Atrophic acne scars

However, one of the primary concerns for patients considering this treatment is whether their scars will reappear after laser therapy.

This article aims to provide a comprehensive understanding of the factors that determine scar recurrence and the effectiveness of laser treatments in minimizing the likelihood of scars coming back.

Types of Scars and Laser Treatments

Acne scars:

  • These result from the inflammation and damage caused by acne breakouts, leading to various types of scars, including atrophic and superficial scars.

Surgical scars:

  • These are the scars that develop as a result of surgical procedures, such as C-sections or other operations.

Laser treatments:

  • Various types of laser treatments are available to address different kinds of scars. Fractional lasers, ablative lasers, and non-ablative lasers are some common options used for scar treatment.

Factors Affecting Scar Recurrence

  • Individual healing response: Each person’s skin heals differently. And some individuals may be more prone to scarring or experiencing a recurrence of their scars after laser treatment. We have patients who are keloid (overgrowth of scar tissue) formers
  • Type and severity of the scar: The likelihood of scar recurrence may also depend on the type and severity of the scar being treated. More severe scars may require multiple treatments or a combination of therapies to achieve the best results.
  • Post-treatment care: Proper post-treatment care is essential in preventing scar recurrence. Patients should follow their practitioner’s recommendations, including using appropriate skincare products, protecting their skin from the sun, and avoiding activities that could cause additional damage or irritation to the treated area.

Preventing Scar Recurrence After Laser Treatment

Multiple treatment sessions: 

In some cases, multiple laser treatment sessions may be necessary to achieve optimal results and minimize the risk of scar recurrence. Practitioners will typically recommend a series of treatments based on the patient’s specific needs and the type of laser being used.

Combination therapies

Combining laser treatments with other therapies, such as chemical peels or microneedling, can help improve the overall effectiveness of scar treatment and reduce the likelihood of recurrence.

Maintenance treatments:

Periodic maintenance treatments may be recommended to help maintain the results achieved through laser therapy and prevent scar recurrence.


A lot of people say that laser treatments are too costly or invasive, making other treatment options more appealing. However, the long-term benefits of laser treatments, such as reduced scarring and improved skin texture, often outweigh the costs and potential discomfort associated with the procedure.


In conclusion, while there is always a risk of scar recurrence after laser treatment, several factors can help minimize this risk. These include the patient’s individual healing response, the type and severity of the scar, and proper post-treatment care.

By undergoing multiple treatment sessions, considering combination therapies, and maintaining the results with periodic maintenance treatments, patients can significantly reduce the likelihood of their scars coming back after laser therapy.

It is essential to consult with a qualified medical professional to discuss the most suitable treatment options for each individual’s unique needs and circumstances.
