A standard spa facial will not meaningfully improve acne scars. The cleansing, steaming, and moisturizing steps of a classic facial only affect the outermost layer of skin, while acne scars sit deeper in the dermis. That said, certain medical-grade facial treatments, like chemical peels and microneedling, can make a real difference depending on the type of scar you have.
Why Scar Type Matters
Not all acne scars are the same, and what works for one type may do nothing for another. About 80 to 90 percent of people with acne scars have atrophic scars, meaning the skin lost collagen during healing and left behind a depression. The remaining minority have hypertrophic or keloid scars, where the body overproduced collagen and created raised, firm tissue.
Atrophic scars come in three varieties. Ice pick scars are narrow (under 2 mm wide) and extend deep into the skin like a small puncture. Boxcar scars are wider with sharp vertical edges, similar to chickenpox marks. Rolling scars are the broadest, typically over 4 to 5 mm wide, caused by bands of tissue pulling the skin downward and creating a wavy, uneven surface.
Then there’s post-inflammatory hyperpigmentation, the flat dark or red marks left behind after a breakout. These aren’t true scars because they involve color change rather than structural damage. This distinction matters because surface-level facial treatments are far more effective against pigmentation than they are against deep, pitted scars.
What a Standard Facial Can and Can’t Do
A traditional facial, the kind you’d book at a day spa, typically includes cleansing, exfoliation, extraction, a mask, and moisturizer. These steps improve surface texture and give skin a temporary glow, but they don’t reach the dermal layer where scar tissue forms. Microdermabrasion, which uses fine particles to buff the skin’s surface, falls into the same category. It’s effective as a quick pick-me-up for dull skin, but acne scars sit too deep for it to correct.
HydraFacial is a popular upgraded option that combines suction, exfoliation, and serum infusion. Imaging studies show it thins the outermost layer of dead skin cells from about 9.4 to 6.7 micrometers immediately after treatment, and all subjects in one study reported smoother skin texture afterward. But at a two-week follow-up, researchers found no visible difference in the quality or quantity of collagen fibers in the dermis. For acne scars specifically, the research suggests a multimodal approach is needed, meaning HydraFacial alone isn’t enough.
Chemical Peels: The Facial That Actually Helps
Chemical peels are the facial treatment with the strongest evidence for acne scars, particularly for shallow boxcar scars and pigmentation. These aren’t the gentle peels you’d find in a basic facial. Medium-depth peels use acids at concentrations high enough to penetrate through the outer skin and into the upper dermis, triggering controlled damage that forces the skin to rebuild with fresh collagen.
Glycolic acid at 70% and trichloroacetic acid (TCA) at 30% both function as medium-depth peels and have been studied for mild-to-moderate acne scars. In comparative research, glycolic acid and a salicylic-mandelic acid combination both produced significant improvement in boxcar scars. Rolling scars, however, showed no significant response, and ice pick scars improved only minimally. That pattern holds across most surface-level treatments: the wider and shallower the scar, the better the results.
Peels typically require multiple sessions spaced several weeks apart. Superficial peels need more sessions with less downtime, while medium-depth peels involve a few days of peeling and redness but fewer total treatments.
Microneedling: Collagen Rebuilding for Deeper Scars
Microneedling creates thousands of tiny punctures in the dermal layer, triggering the skin’s wound-healing response and increasing collagen and elastin production. It’s one of the more effective treatments for atrophic acne scars across all three subtypes.
Clinical data shows meaningful improvement. In one study, 73% of patients with severe (grade 4) scars improved by two full grades on a standardized scale. All patients with mild (grade 2) scarring improved to near-normal skin. In a separate study, about 18% of patients reported 75 to 100% improvement in their acne scars, roughly a quarter saw 50 to 74% improvement, and 55% perceived 25 to 49% improvement. These aren’t overnight results. Most microneedling protocols involve three to six sessions spaced four to six weeks apart, with continued collagen remodeling happening for months after the final session.
Microneedling is sometimes offered as part of a “facial” at medical spas, which can blur the line between a cosmetic facial and a medical procedure. If you’re booking microneedling for acne scars, the provider’s training and the needle depth they use matter significantly. Deeper scars need longer needles that penetrate further into the dermis.
LED Light Therapy
Red light therapy, commonly included in high-end facials, stimulates fibroblasts (the cells that produce collagen) and is promoted for scar improvement. It increases collagen production and can improve skin’s overall structure and elasticity over time. However, the effect is mild compared to treatments like microneedling or medium-depth peels. Red light works best as a complement to more aggressive treatments rather than a standalone solution for visible scarring.
Matching Treatment to Your Scar Type
The most practical way to think about this is by matching the depth of treatment to the depth of damage:
- Flat dark or red marks (post-inflammatory hyperpigmentation): These respond well to gentle chemical peels, HydraFacials, and consistent use of brightening serums. They also fade on their own over months to years.
- Shallow boxcar scars: Medium-depth chemical peels and microneedling both show good results. Multiple sessions are needed.
- Rolling scars: Microneedling can help by breaking up the fibrous bands pulling the skin down. Chemical peels alone have limited effect on this type.
- Ice pick scars: These are the most stubborn. Surface treatments including peels show minimal improvement. Procedures like TCA cross (where acid is applied directly into individual scars at high concentration) or laser resurfacing are typically needed.
- Raised or hypertrophic scars: These require a completely different approach since the problem is too much collagen, not too little. Standard facials and even microneedling are not appropriate here.
Setting Realistic Expectations
No single facial treatment, no matter how advanced, will erase acne scars completely. The goal with any treatment is improvement, not perfection. Mild scars can sometimes become nearly invisible. Deep ice pick and boxcar scars can be softened and reduced but rarely eliminated entirely.
Timing also matters. Collagen remodeling is a slow biological process. You won’t see the full effect of a treatment series for three to six months after your last session. Combining treatments often produces better results than relying on one modality alone. A dermatologist might recommend peels for surface texture, microneedling for collagen rebuilding, and laser for the deepest scars, all in a staged approach over several months. If you’re investing in scar treatment, a consultation that identifies your specific scar types will help you avoid spending money on treatments that can’t reach the problem.
