How Many Sessions Do You Actually Need for Acne Scars?
Clinical studies have quantified just how ineffective microdermabrasion is for acne scarring. Patients with moderate-to-severe acne scarring required an average of 15.2 microdermabrasion treatments just to see any improvement—not dramatic improvement, but “good, fair, or no improvement” after six to seven months of aggressive treatment every two weeks. Some patients required more than 20 passes per session just to target deeper scar tissue. At $173 per session (the RealSelf average), that’s $2,595 spent on an average course of 15 treatments.
The catch: those studies showed patients had mixed results even after investing that time and money. Some saw fair improvement. Others saw nothing. For someone with deep scars, burning through $2,500 on microdermabrasion is a financial and emotional gamble with odds stacked against a good outcome. This is why dermatologists rarely recommend microdermabrasion as a standalone solution for acne scarring.

What Actually Works Better for Deep Acne Scars?
If you have deep acne scars and microdermabrasion isn’t the answer, what is? Fractional laser resurfacing, microneedling, chemical peels, and full dermabrasion are all more effective for moderate-to-deep scarring. Fractional laser resurfacing penetrates deeper into the dermis and stimulates collagen remodeling, making it far superior for ice-pick and boxcar scars—though it’s more expensive ($1,000-$3,000 per session) and requires downtime. Microneedling with radiofrequency also reaches the dermis and is more affordable ($300-$700 per session) with similar effectiveness to fractional laser but usually requiring four to six sessions for noticeable results.
Chemical peels, depending on depth, can address moderate scarring and cost $100-$300 per session but work best when combined with other treatments. Full dermabrasion is the most aggressive option, essentially surgical skin resurfacing, and is reserved for severe cases because it carries higher risks—but for someone truly committed to scar reduction, it delivers better results than microdermabrasion. The trade-off with these alternatives is downtime: fractional laser and microneedling require several days to a week of healing, whereas microdermabrasion has virtually no downtime, which is part of why people chase it despite poor results.
The Package Deal Trap and Real-World Costs
Many clinics aggressively push package deals—”buy six sessions at $150 each instead of $175″ or “prepay for ten sessions and save 20%.” The math looks attractive, but there’s a behavioral trap: you’ve committed $1,500-$1,800 upfront for treatments that statistically are unlikely to deliver the results you want. If you’re paying per session, you can quit after three or four sessions when you realize nothing is changing. If you’ve prepaid for ten, you’re more likely to keep going, hoping the next session will finally show results.
Real-world example: someone with deep boxcar scars books a package of eight sessions at $130 each ($1,040 total), comes back for a third appointment, sees no meaningful change in scarring, but feels committed to finishing the package because the money’s already spent. By session eight, they’re out $1,040 and their scars look identical to when they started. They would have been better off spending $600 on a consultation with a dermatologist to learn that fractional laser or microneedling would actually work for their scar type.

When Microdermabrasion Might Have a Role
There are scenarios where microdermabrasion is useful, but almost never as a standalone scar treatment. Dermatologists sometimes recommend it as part of a combination approach: after a course of fractional laser, microdermabrasion might help smooth remaining rough texture. After microneedling or chemical peels, gentle microdermabrasion can remove flaking skin during healing.
Some people with very mild, shallow scars—the kind barely visible in normal lighting—might see improvement with a few microdermabrasion sessions combined with tretinoin or other collagen-boosting treatments. It’s also genuinely useful for non-scar concerns like rough skin texture, sun damage, and clogged pores, where it shines. But for the deep, indent-like acne scars that bother most people enough to seek treatment, microdermabrasion alone is not the answer.
Before You Book: How to Assess Your Own Scarring
Before spending $100-$250 on a microdermabrasion session, get clear on what you’re actually dealing with. Look at your scars in natural lighting and ask: are they barely visible, or do they cast a visible shadow on the skin? Can someone see them from across a room, or are they only noticeable up close? Are they small and pinpoint (ice-pick), wide and rounded (rolling), or angular and box-like (boxcar)? If you can see clear shadows or depth, you have moderate-to-deep scars that need something stronger than microdermabrasion.
A board-certified dermatologist can assess your specific scar type in 10 minutes and recommend the right tool—and honestly, that $150-$250 dermatology consultation will save you thousands in ineffective treatments. Many dermatologists will credit that consultation fee toward treatment if you book with them, so it’s not wasted money.
Conclusion
Microdermabrasion is affordable and convenient, costing $100-$250 per session with no downtime. But affordability and convenience don’t matter if the treatment doesn’t work. For deep acne scars, it doesn’t.
Clinical evidence shows that patients need an average of 15 treatments and still see only fair-to-mixed results, making it a poor investment for moderate-to-severe scarring. If you’re struggling with visible acne scars, talk to a dermatologist about fractional laser, microneedling, or chemical peels—treatments that actually penetrate to the depth where scar tissue lives. Microdermabrasion has a place in skincare, but treating deep acne scars isn’t it.
