Acne scars are enduring marks or depressions that form on the skin post-healing from active acne. They present as discoloration, textural irregularities, or indentations, with diverse types like icepick, boxcar, rolling, hypertrophic, and atrophic scars. These scars alter skin texture, causing roughness, unevenness, or discoloration. Treatments like laser therapies and chemical peels target minimizing their visibility and improving overall skin condition, effectiveness varying based on scar type and severity.

How do acne scars form?

Active pimples, while on the path to healing, frequently leave behind noticeable traces on the skin. These traces can manifest as indentations or discoloration. Initially, these marks may have a pink hue, which typically fades back to the natural skin color as the healing progresses. However, in certain cases, the marks may persist as pink, indicating either suboptimal healing or damage to blood vessels.

The presence of these scars introduces depressions and irregularities on the skin surface, contributing to a rough, loose, and lackluster appearance. Additionally, when acne scars are deep, there is often an associated reduction in subcutaneous fat tissue. This interplay of factors underscores the complexity of the impact that acne scars can have on the skin’s texture and overall appearance.

What are laser treatments for acne scars?

Several laser treatments are available for addressing acne scars. Among them, the CO2 fractional laser is considered one of the most effective. The wavelength of the CO2 fractional laser is 10,650 nm, allowing it to reach all layers of the skin. This laser can renew the skin from the superficial to the deepest layers, making it versatile in treating various types of acne scars.

The CO2 fractional laser treatment can contribute to a significant reduction in acne scars, ranging from 40% to 90%. The extent of improvement depends on factors such as the depth and size of the scars. For shallower and smaller scars, the benefits are typically more pronounced, and in some cases, these scars may even disappear. However, for deeper and larger scars, combining laser treatment with fillers can enhance the overall results.

The recommended frequency for CO2 fractional laser sessions is around 4-6 sessions per month. The recovery period is relatively short, with patients experiencing temporary brown flaking or redness on the skin for 3 to 5 days after each session. Overall, CO2 fractional laser treatment is considered one of the most effective methods for reducing acne scars.

Which laser is most effective for treating acne scars?

The wavelength of lasers is typically around 1000 nm, while other fractional lasers (erbium; Er-yag, Er-glass) are around 2000 nm. In contrast, the wavelength of CO2 fractional laser is 10,650 nm, making it the only laser that can reach all layers of the skin. Other laser treatments only affect the upper layer of the skin and do not provide improvement or impact in the deeper layers. CO2 fractional laser allows for rejuvenation of all layers of the skin, from the superficial to the deepest layers.

How much do acne scars improve with laser treatment?

Since CO2 fractional laser can completely renew the skin, it contributes to reducing acne scars by 40-90%. It is considered one of the most effective methods for reducing acne or acne scars.

The extent of improvement depends on the superficiality and size of the scars; smaller and shallower scars tend to show more improvement, and in some cases, they may even disappear. However, for very deep and large scars, the success is more limited. Therefore, applying fillers to areas with deep and large scars can significantly enhance the results.

How many sessions are required for laser treatment of acne scars?

CO2 fractional laser treatment is typically administered at an average of 4-6 sessions per month.

How long does the recovery period for acne scars treatment take?

There is usually a 3 to 5 day period of brown flaking or redness on the skin after the treatment. The patient can shower, apply makeup the next day, and use moisturizing cream with the assistance of cold packs. Treatment is preferably done during seasons and months with less sunlight, typically between October and April.
