Acne scars come in three main types: ice-pick (deep, narrow), boxcar (shallow, wide), and rolling (undulating). Ice-pick scars are the most resistant to standard treatments. The protocols that actually work in 2026: TCA CROSS, fractional CO₂, and Morpheus8 — usually layered.
TCA CROSS for ice-pick specifically
Trichloroacetic acid Chemical Reconstruction of Skin Scars (CROSS) — 70–100 % TCA applied directly into individual ice-pick scars. Causes controlled re-epithelialization that fills the scar over 3–6 months. 2–4 sessions, 6 weeks apart.
CROSS is the only treatment specifically designed for ice-pick scars. Most other treatments don't reach the scar depth effectively.
Fractional CO₂ for surrounding texture
Resurfaces the broader scar field while CROSS treats individual deep pits. Combined protocol = significantly better than either alone. CO₂ acne scar guide. Elyzea CO₂ acne scars: S/1,000 (~US$286).
Morpheus8 for collagen remodeling
Adjunctive — RF microneedling at 3–4 mm depth remodels the deeper dermal scar tissue. Works synergistically with CO₂. Morpheus8 acne scar protocol.
Why other treatments don't work alone for ice-pick
Subcision: better for rolling scars. Filler: temporary. Microneedling alone: doesn't reach depth. Punch excision: option for very deep individual scars but leaves a different kind of mark.
Each treatment has its place but ice-pick specifically needs CROSS as the primary tool.
Realistic timeline
Combined protocol over 6–9 months produces 70–85 % improvement in ice-pick scars. Full disappearance is rare but ice-pick scars can become significantly less visible.
Patience essential — collagen remodeling takes months.
Patient selection
Latin/dark skin: extreme caution with CO₂ — strict pre-treatment hydroquinone protocol required, and some patients are better served by Morpheus8-only protocols.
Severe scarring across full face: more sessions needed, more conservative approach.
Combined-protocol example
Multi-trip strategy:
- Trip 1: TCA CROSS on ice-pick scars + Morpheus8 facial
- Trip 2 (6-8 weeks later): CROSS session 2 + Morpheus8 session 2
- Trip 3 (4-6 weeks later): Fractional CO2 laser facial in Lima, Peru
- Trip 4 (8-12 weeks later): Final Morpheus8 + assessment
Cost estimate
Comprehensive protocol over 9-12 months at Elyzea: ~US$2,000-$3,000 vs $10,000-$20,000 in the US.
Frequently asked questions
What if I have all three scar types?
Combined protocol addresses each: CROSS for ice-pick, subcision for rolling, CO2 for boxcar.
Can I treat fresh acne scars?
Wait until acne is controlled. Active acne complicates treatment.
What about isotretinoin patients?
Wait 6+ months post-isotretinoin before laser treatments.
Are dermal fillers helpful?
Temporary improvement. Not a long-term solution.
How does this compare to dermabrasion?
Old-school dermabrasion has been replaced by fractional laser + RF microneedling.
Will scars come back?
No — treated scars stay treated. New scars from new acne possible.
Best skincare during treatment?
Gentle, barrier-supporting, mineral SPF 50+. Avoid actives during recovery phases.
Why Elyzea is different in Lima
Every treatment at Elyzea is evaluated by Dra. Geldres, a board-certified plastic surgeon — not delegated to a technician with a sales quota. Genuine equipment, conservative parameters, honest expectations. How visits work.
What the free virtual consultation covers
Before any travel, a free virtual consultation reviews your goals, candidacy and exact pricing — so you fly with a confirmed plan, not a sales pitch. Book it and plan your visit here.
Transparent pricing — no surprises
Every treatment Elyzea offers is published on our public price list (prices.md in the website repository, mirrored on the price pages). The free virtual consultation determines protocol, sessions, and any combination plan; the per-session prices on the public list are what you pay. There are no opaque "personalized quotes" that scale to perceived ability to pay, no pressure-package upsells, and no surprise invoice items at checkout.
Anesthesia tier (topical, nerve block, oral sedation, or conscious IV sedation) is matched to the protocol depth and discussed transparently at consultation. When a treatment is part of a multi-modality plan (HIFU + Morpheus8, fillers + CO₂, etc.), the full cost is mapped out before any commitment. Lima pricing reflects local cost structure — significantly below US clinics for the same FDA-cleared technology — and the public price list ensures the savings actually reach the patient.

Bottom line
TCA CROSS + fractional CO2 + Morpheus8 layered protocol = 70-85% ice-pick scar improvement. Multi-trip strategy over 9-12 months. Lima costs ~$2,000-$3,000 vs $10,000-$20,000 in US for equivalent.
