Instead of a smooth surface, small pits or craters form. These are called pitted or atrophic scars. The good news? Modern treatments at clinics like RETENS can smooth away scars and restore confidence. This easy guide covers Think of your skin like a road. Healthy skin is smooth asphalt.
Why do acne scars form?
- Top treatments for scar repair.
- Simple at-home care.
- How to choose the right treatment plan
Wider, round or oval depressions with steep, defined edges (like old railroad boxcars).
1. What Are Depressed Acne Scars (凹凸洞)?
Topical retinoids: Products with retinol or prescription retinoids speed cell turnover and encourage collagen. Start slow (1–2 times a week).
These are known as:
- Ice-pick scars: Deep, narrow pits that look like someone poked the skin with a sharp tool.
- Boxcar scars: Hard to treat because they reach deep into the dermis.
- Rolling scars: Broad, wave-like depressions that give skin a rolling, undulating appearance.
All these scars fall under the umbrella of 暗瘡凹凸洞. They differ from flat discoloration (post-inflammatory hyperpigmentation), because they are true textural changes—tiny holes and valleys in the skin.
2. Why Do Acne Scars Form (暗瘡疤治療)?
暗瘡凹凸洞 form when deep inflammation damages the skin’s collagen framework:
- Inflamed lesion: A cyst or nodule damages tissue deep within the skin.
- Collagen loss: In the healing process, the body may not rebuild collagen fully, leading to a pit.
- Scar maturation: Over time, the pit can become more defined as surrounding skin tightens.
Factors that increase scarring risk:
- Picking or squeezing pimples.
- Severe cystic acne.
- Delayed treatment of active breakouts.
- Genetic tendency toward scarring.
Understanding why scars form helps you prevent new ones—and choose the right repair treatments.
3. Top Treatments for Acne Scar Repair (凹凸洞修復)
Knowing your scar types helps pick the right treatment. Modern treatments can greatly improve skin texture. You don’t have to live with those “potholes” forever!
Here are the most popular, proven options:
A. Laser Skin Resurfacing
Fractional CO₂ laser or Erbium laser resurfaces the skin by creating micro-injuries.
Benefits:
- Stimulates collagen deep below the surface.
- Smooths fine lines and shallow scars.
- Evens overall texture
A typical course is 3–5 sessions, spaced 4–6 weeks apart. Mild redness lasts a few days; healing yields fresher, smoother skin.
B. PicoSure / Pico Laser
Picosecond lasers (PicoSure) deliver ultra-fast energy bursts that break scar tissue apart with minimal heat.
Benefits:
- Less downtime than traditional lasers.
- Effective on deeper scars and pigmentation.
- Boosts collagen quickly.
Usually 2–4 treatments are enough, with mild redness or pinpoint bleeding that fades in 24–48 hours.
C. Microneedling (Collagen Induction Therapy)
Tiny needles create controlled micro-injuries, prompting natural collagen repair.
Benefits:
- Improves skin firmness and texture.
- Reduces scar depth gently over time.
- Minimal downtime—just redness for 1–2 days.
Pair microneedling with PRP (platelet-rich plasma) or growth factors for extra boost. Recommended 4–6 sessions, 4 weeks apart.
D. Subcision
A fine needle is inserted under the scar to release fibrous bands pulling the skin down.
Benefits:
- Immediately raises rolling scars.
- Allows natural collagen to fill the space.
- Can be combined with filler for instant lift.
Usually a single session is enough, though deeper scars may need retreatment.
E. Dermal Fillers
Hyaluronic-acid fillers like Restylane or Juvederm are injected into scars to plump pits.
Benefits
- Instant improvement in depth.
- Minimal discomfort with numbing cream.
- Results last 6–12 months.
Ideal for boxcar and rolling scars. Fillers can be repeated as needed.
F. Chemical Peels
Medium-depth peels (TCA) or Jessner’s solution remove top layers of skin and stimulate renewal.
Benefits:
- Unclogs pores, evens tone.
- Improves shallow scars and texture.
- Quick treatment, light peeling for 3–5 days.
Multiple peels (3–6) spaced 3–4 weeks apart yield the best results.
4. Simple At-Home Care for Better Results
Between professional treatments, these easy steps speed healing and reduce scarring:
Gentle Cleansing
Use a mild, non-foaming cleanser twice daily. Avoid harsh scrubs.
Exfoliation
A BHA (salicylic acid) toner 2–3 times a week clears dead cells and prevents clogged pores.
Hydration
A lightweight, non-comedogenic moisturizer keeps skin supple and supports collagen.
Sun Protection
Daily SPF 30+ is crucial. UV rays worsen scars and slow healing.
Avoid Picking
Hands off! Picking at 凹凸洞修復 causes more inflammation and deeper scars.
Healthy Lifestyle
A device with fine needles creates micro-injuries that boost collagen production.
5. Choosing Your Best Treatment Plan
Because 暗瘡疤治療 vary, a customized plan works best. Consider:
- Scar type: Ice-pick vs. boxcar vs. rolling.
- Skin tone: Some lasers suit darker skin better.
- Downtime: How much recovery you can handle.
- Budget & goals: Immediate filler vs. gradual laser results.
A RETENS Medical Beauty consultation will match you with the right combo—like microneedling plus PicoLaser, or subcision with filler—to get you smooth, confident skin.
