Acne scars are often the last thing to fade after breakouts clear. If you’ve tried topical treatments without much change in texture, I frequently recommend Fraxel laser therapy as one of the most effective options available for acne scarring.
Fraxel is an FDA-approved fractional laser that treats microscopic areas of skin while leaving the surrounding tissue intact. This triggers your body’s own collagen and elastin production, which is what actually rebuilds smoother skin over time. In this post, I’ll walk through what a Fraxel treatment involves, what results to expect, and how it compares to other scar treatments.
How Fraxel Improves Acne Scars
Fraxel uses fractional photothermolysis: it creates controlled micro-injuries in the skin, which triggers collagen regeneration and gradually replaces damaged tissue with smoother skin. In my experience, patients typically notice:
- Smoother skin texture
- Reduced depth and discoloration of scars
- More even skin tone
Visible improvement usually begins within 3 to 6 weeks, with most patients needing 3 to 5 sessions spaced 4 to 6 weeks apart. Results continue to improve for several months as collagen builds.
What to Expect During Treatment
Before: I cleanse the treatment area and apply numbing cream for 30 to 45 minutes.
During: The session itself takes 20 to 60 minutes. Most patients describe it as feeling like a rubber band snap or mild sunburn, tolerable with numbing cream.
After: Expect redness and swelling for 3 to 7 days. I recommend avoiding sun exposure, using gentle skincare, and wearing broad-spectrum SPF daily to protect healing skin.
How Well Fraxel Works by Scar Type
| Scar Type | Response to Fraxel |
|---|---|
| Boxcar Scars | Good response |
| Rolling Scars | Very good response |
| Ice Pick Scars | May need combo therapy |
Benefits and Limitations
Benefits: Stimulates collagen and elastin, minimizes scar depth and texture, improves pigmentation, treats fine lines and sun damage, and has less downtime than ablative lasers.
Limitations: Expect temporary redness, swelling, and peeling; multiple sessions are required; and it’s not appropriate for active acne.
How Fraxel Compares to Other Options
| Treatment | Avg. Cost | Downtime | Effectiveness |
|---|---|---|---|
| Fraxel | $1,000 | 5–7 days | High |
| Chemical Peels | $300–$600 | 7–14 days | Moderate |
| Microneedling | $100–$700 | 2–4 days | Moderate |
| Subcision | $200–$400 | 2–4 days | High (for deep scars) |
How Long Results Last
Fraxel results are long-lasting, and I typically see improvements hold for years when patients keep up with sun protection and a consistent skincare routine. I recommend broad-spectrum SPF 30–50 with zinc oxide daily.
Possible Side Effects
Fraxel is safe for most patients, though possible side effects include temporary redness, swelling, and peeling; a risk of hyperpigmentation, especially in darker skin tones; and rarely, infection or prolonged inflammation. Choosing an experienced provider helps minimize these risks.
How Many Sessions You’ll Need
Most patients need 3 to 5 sessions spaced 4 to 6 weeks apart. You’ll typically notice results after just a few sessions, with full results developing over up to 6 months. How quickly and how well you respond depends on your skin type, scar age and severity, and how closely you follow aftercare.
Is Fraxel Right for You?
Fraxel is one of the most effective options I offer for long-lasting acne scar improvement without major downtime. If you’re considering it, I’d be glad to talk through whether it’s the right fit for your scars during a consultation.
