Is this an atrophic scar or depressed scar on my arm? Can it be fixed by microneedling? (Photos)

At least from the photos provided, it appears that the scar appears not to be particularly Indented, but rather a crinkly, hypopigmented scar. I have been performing manual dermarolling microneedling (no need for the added expense and risks of RF microneedling) with gratifying results for over twenty-five years for treating superficial, surface textural and pigmented changes, of the kinda seen in the photos.
You would be wise to make sure to consult with an experienced, board certified cosmetic dermatologist scar treatment specialist and to exercise a healthy dose of "buyer beware" if offered any of the expensive, so-called "next big thing" RF or light-based therapies, since the hard science to support the use of these gizmos lags well behind the heavy marketing hype and social media buzz to promote them.
Hope this helps and best of luck.

Atrophic and depressed scars are terms often used interchangeably to describe scars that are sunken or indented compared to the surrounding skin. These types of scars occur when there is a loss of tissue, which can happen after an injury like a cut from broken glass.

Microneedling for Atrophic/Depressed Scars:

Microneedling is a popular treatment for atrophic or depressed scars. It works by creating tiny punctures in the skin, which stimulates the body's natural wound healing processes, including collagen and elastin production. This can help improve the texture and appearance of the scar over time.

Considerations:

Effectiveness: Microneedling can be effective for improving the appearance of atrophic scars, but results can vary depending on the severity and age of the scar, as well as individual skin characteristics.

Sessions Required: Multiple sessions are usually needed to achieve noticeable improvement. The number of sessions can vary based on the scar's depth and size.

Professional Treatment: It's important to have microneedling performed by a qualified professional to ensure safety and effectiveness.

Limitations: While microneedling can improve the appearance of scars, it may not completely eliminate them. Setting realistic expectations is important.

If you are considering microneedling, consulting with a dermatologist or a qualified skincare professional can provide personalized advice and help determine if this treatment is suitable for your specific scar.

Hi there,
Thank you for sharing your question and photos. Based on what I can see, the scar on your arm appears to be a linear, mature atrophic scar, which is slightly sunken due to tissue loss — often referred to as a “depressed scar.” These two terms are commonly used interchangeably in such cases.
Microneedling can help improve the appearance of this type of scar by stimulating collagen production. With consistency — usually 4 to 6 sessions — you can expect gradual softening and blending of the scar. While it won’t completely remove the scar, it can make it less noticeable.
In addition to microneedling, you might also consider Fotona laser treatment if it ever becomes an option for you. Fotona’s dual-wavelength system is excellent for scar remodeling — it not only improves the texture and depth of atrophic scars but also enhances skin tone and elasticity. It’s often more effective when combined with microneedling or used as a second-line option.
If microneedling is currently the most affordable option for you, it’s still a solid place to start — just be sure to have it done by a medical professional using a clinical-grade device.
Wishing you great results in your journey,Dr. Mustafa AydınolPlastic, Reconstructive & Aesthetic Surgeon
