Acne scars significantly impact self-esteem and overall appearance, often persisting despite conventional treatments. Caused by clogged pores, bacteria, and inflammation, these scars leave lasting marks. Fortunately, advancements in laser technology offer effective solutions by targeting deeper skin layers to diminish inflammation, clear acne, and promote collagen production for scar reduction. Although acne scars cannot be totally removed, this treatment can lessen their visibility and the discomfort they cause. You might not be a good candidate for this treatment if you have severely wrinkled skin, a darker skin tone, or active acne.  

Dr. Joy Shah, dermatologist and founder of Beagle Lasers, shared with HT Lifestyle the top five aesthetic laser treatments that are currently highly sought after.

Top aesthetic laser treatments for acne scars

1. Fractional CO2 Hybrid

One of the most effective methods for reducing acne scars is the Fractional CO2 laser treatment. This method employs carbon dioxide lasers to systematically remove damaged skin layers. By creating microscopic wounds, the laser triggers the body's natural healing response, encouraging collagen synthesis and the regeneration of new skin cells. For instance, HyGrid lasing technology has garnered attention for its exceptional outcomes.

It allows precise customisation of the ablative (CO2 laser) and non-ablative (1570nm laser) ratio via a meticulously designed matrix of micro-dots tailored to each patient's unique requirements. Patients typically experience significant enhancements in skin texture and appearance following a series of sessions. This treatment is particularly effective for addressing deep scars and offers long-lasting results.

2. Microneedling Frequency

Microneedling RF combines traditional microneedling with radiofrequency energy to stimulate collagen production and skin tightening. This dual-action approach effectively treats acne scars, catering to those preferring minimally invasive options. Nano radiofrequency (RF) technology further enhances this, reducing textural irregularities and addressing acne-related skin damage.

It works through microcrystalline penetration, facilitating cosmetic absorption, targeting hair follicles, sebaceous, and sweat glands while inhibiting inflammation. Customised treatment plans ensure smoother, healthier skin with minimal downtime. This innovative, non-surgical solution promises enduring results, offering a more youthful complexion for those troubled by acne scars.

3. Erbium YAG Laser

The Erbium YAG laser is instrumental in treating acne due to its precise targeting of skin imperfections. Emitting high-energy light pulses effectively vaporizes damaged skin cells and bacteria, reducing acne lesions. Its ability to penetrate the skin at controlled depths allows for bespoke treatment of acne scars and active breakouts. The laser's thermal effect also stimulates collagen production, promoting skin regeneration and a smoother complexion. Regular sessions can lead to significant improvements in skin texture and clarity, restoring confidence in those affected by acne.

4. Pulse Dye Laser

The Pulsed Dye Laser (PDL) is effective in reducing redness and improving the texture of acne scars. This laser works by targeting blood vessels in the scar tissue, causing them to collapse and be reabsorbed by the body. PDL is particularly useful for treating hypertrophic scars and keloids, which are raised and often red or purple in colour. This treatment involves minimal discomfort and no significant downtime, but it may require several sessions and is less effective on deep scars.

5. Picosecond Laser

Picosecond laser treatment offers a revolutionary approach to acne management by delivering ultra-short pulses of laser energy to target acne lesions. This high-energy light effectively breaks down pigmentation and bacteria within the skin, leading to reduced inflammation and acne severity. The rapid pulse duration minimizes heat diffusion, ensuring precise and safe treatment with minimal discomfort. Additionally, picosecond laser therapy stimulates collagen and elastin production, promoting skin healing and regeneration, which aids in reducing acne scarring.

Prior consultation with a certified dermatologist or skincare specialist is essential when selecting a treatment to minimize potential side effects. They will assess the nature and severity of your scars, as well as your skin type, to recommend the most suitable approach. With a variety of laser technologies offering unique benefits, the best choice depends on individual needs and desired results.
