Laser Facial for Acne Scars and Texture: HALO vs TRL vs Secret RF

Acne may fade, but the scars it leaves behind often stay for years. Many people struggle with texture irregularities even after their breakouts end. Acne scars form when inflammation disrupts collagen during the healing process. This can create indentations, raised marks, or uneven skin patterns that topical skincare cannot correct.

Several types of acne scars exist. Common examples include:

• Ice pick scars
• Boxcar scars
• Rolling scars
• Atrophic scars
• Post-inflammatory discoloration
• Rough texture caused by chronic congestion

This guide breaks down how each treatment works, what types of scars they improve, the downtime involved, and how to choose the best option for your skin goals.

The challenge is that these scars sit in the deeper layers of the skin. Surface-level treatments like exfoliation or chemical peels often help brightness and tone, but they do not rebuild the collagen that has been lost. That is why laser and energy-based treatments have become the gold standard for improving acne scars. These technologies reach the layers of the skin where collagen forms and where scars actually live.

At New Beauty and Wellness, several advanced treatments address acne scars and texture concerns. The most notable are the HALO Hybrid Fractional Laser, the Tunable Resurfacing Laser (TRL), and Secret RF Microneedling. Each offers a unique approach to stimulating collagen, resurfacing the skin, and smoothing uneven texture.

HALO is a hybrid fractional laser that delivers both ablative and non-ablative wavelengths in a single treatment. This dual action makes it a powerful tool for improving acne scars and overall texture.

Unlike older lasers that relied on a single wavelength, HALO delivers two types of laser energy at the same time:

• Ablative wavelengths that remove damaged skin cells
• Non-ablative wavelengths that heat the deeper layers to stimulate collagen

This combination allows HALO to improve the skin surface while also remodeling deeper scar tissue.

• Mild to moderate acne scars
• Rough texture
• Enlarged pores
• Fine lines and early signs of aging
• Sun damage and discoloration
• Overall tone improvement

It is especially helpful for people who want good results without the longer downtime associated with more aggressive resurfacing lasers.

During a HALO session, the device creates thousands of controlled microchannels in the skin. These channels trigger the body to rebuild collagen and renew the outer layer of skin.

Most people experience:

• Warmth or prickling during treatment
• Redness and swelling for one to three days
• Peeling and bronzing as the skin resurfaces
• Texture improvement over several weeks

HALO requires less downtime than fully ablative lasers, while still achieving significant improvements in smoothness and clarity.

A single HALO treatment produces noticeable improvement. However, for moderate acne scars or deeper texture issues, a series of two treatments spaced several months apart may be suggested.

For deep, pronounced, or difficult-to-treat acne scars, the Tunable Resurfacing Laser offers one of the most powerful solutions. TRL is a fully ablative laser that removes damaged skin with exceptional precision.

The Tunable Resurfacing Laser is known for:

• Deeper penetration compared to non-ablative lasers
• High precision in removing thin layers of skin
• Customizable settings based on scar depth and skin type

TRL gives providers complete control over the depth of resurfacing. This tunability allows for a custom treatment plan that targets deeper scars without unnecessary damage to surrounding tissue.

• Deep boxcar scars
• Rolling scars
• Thickened scar tissue
• Severe sun damage
• Advanced texture concerns
• Deep wrinkles for mature skin

Of the three treatments compared in this guide, TRL produces the most dramatic resurfacing in a single session.

Because TRL removes tissue more aggressively, the healing period is longer than HALO.

Typical experiences include:

• Redness and swelling immediately after treatment
• Oozing for the first 24 to 48 hours
• Peeling as the skin regenerates
• A recovery window of seven to ten days
• Continued collagen remodeling for months

Although downtime is more noticeable, the results can be transformative for clients with deep or stubborn acne scars.

Many people see significant improvement after one treatment. For very deep scars or multiple scar types, a staged approach may be recommended.

Secret RF Microneedling combines traditional microneedling with radiofrequency energy. This treatment creates micro-injuries while also delivering heat to the deeper layers of the skin. The result is a collagen remodeling effect that firms and smooths the skin.

This device works in two ways:

• Thin needles create controlled microchannels
• Radiofrequency energy heats the dermis to stimulate collagen and elastin

Together, they encourage the skin to rebuild itself from the inside out.

• Mild to moderate rolling scars
• Mild boxcar scars
• Uneven texture
• Early signs of laxity
• Enlarged pores
• Surface irregularities

While it does not remove skin the way TRL does, it excels at remodeling collagen from within, which is essential for atrophic scars.

Secret RF is well tolerated and has a shorter downtime compared to laser resurfacing.

Clients typically experience:

• Redness for one to two days
• Pinpoint scabbing in some cases
• Mild swelling
• Gradual smoothing over several weeks

For clients who want improvement without significant downtime, Secret RF offers an excellent balance between results and recovery.

Most people need a series of three treatments spaced four to six weeks apart. Results build gradually as collagen increases.

Each technology works differently, so choosing the right one depends on the type and depth of the scars.

• Often require deep treatments like TRL
• Occasionally combined with other techniques

• Mild to moderate: HALO or Secret RF
• Deep boxcar scars: TRL

• Secret RF for collagen rebuilding
• HALO for texture refinement
• Combination treatments yield the best results

• HALO or Secret RF
• TRL may be recommended for deeper depressions
• Mixed acne scars
• A combination approach is almost always the best strategy

• Secret RF: One to two days
• HALO: Three to five days
• TRL: Seven to ten days

• Most aggressive: TRL
• Moderately aggressive: HALO
• Least aggressive: Secret RF

Your provider will evaluate:

• Skin tone
• History of pigmentation issues
• Sensitivity
• Current skincare routine
• Lifestyle and social obligations

Darker skin tones often respond better to Secret RF or conservative HALO settings, though this is evaluated on a case-by-case basis.

Many people benefit from a treatment plan that includes more than one of these technologies. Acne scars often vary in depth across the face. Because different tools are better for certain depths, using multiple treatments can produce smoother, more even results.

Examples of combination strategies:

• HALO + Secret RF: HALO resurfaces the upper layers, and Secret RF rebuilds deeper collagen
• TRL spot treatment + HALO full face: TRL is used precisely on deep pits while HALO brightens tone and texture everywhere else
• Secret RF series followed by HALO: Builds foundational collagen first, and laser resurfacing enhances the finish

Customized treatment plans are ideal because no two acne scars are the same. Providers evaluate scar depth, skin type, and overall goals to build the best sequence.

Preparing properly helps maximize results and minimize complications.

Pre-treatment recommendations:

• Avoid active acne flare-ups
• Stop retinoids a few days in advance
• Protect skin from sun exposure
• Follow all skincare guidelines from the provider
• Discuss any history of hyperpigmentation
• Avoid chemical peels or exfoliants before treatment

If the skin is irritated or inflamed, your provider may suggest delaying the session.

Improvement varies depending on scar type and which technology is used. Because collagen remodeling takes time, full results may appear gradually.

Most clients experience:

• Smoother skin
• Smaller appearing pores
• More even tone
• Reduced depth of scars
• Increased firmness
• Brighter complexion

Results often continue to build over three to six months.

After any resurfacing or collagen-stimulating treatment, long-term care is important.

Maintenance practices include:

• Daily sunscreen
• Avoid picking or exfoliating too soon
• Use gentle cleansers and moisturizers
• Follow a consistent skincare routine
• Consider touch-up treatments as needed
• Maintain a healthy lifestyle

Avoiding sun exposure is especially important, since UV damage can worsen pigmentation and texture.

Laser and RF treatments are recommended when:

• Scars are persistent
• Texture affects confidence
• Topical products do not make a meaningful change
• You want lasting improvement
• You prefer non-surgical options

The best way to know which treatment matches your skin is to meet with a provider who specializes in multiple resurfacing technologies and can tailor the plan to your needs.
