Acne scars (凹凸洞) are permanent marks left by severe acne, affecting skin texture and appearance. Various treatments, such as laser therapy, microneedling, and chemical peels, can help improve skin smoothness. Understanding the scar type is key to choosing the right treatment.

Types of Acne Scars (凹凸洞類型)
1. Ice Pick Scars (冰鑿型)
- These scars are deep and narrow, resembling small holes in the skin.
- They form when acne extends deep into the skin, damaging collagen.
2. Boxcar Scars (車廂型)
- These scars have well-defined edges and a broad, shallow depression.
- They are caused by inflammatory acne that destroys skin tissue.
3. Rolling Scars (滾動型)
- These scars have an uneven, wavy texture.
- They form due to tethering of the skin by fibrous bands underneath.
Early 凹凸洞痕跡治療 is crucial, as older scars are harder to treat due to collagen degradation.
Causes of Acne Scars
- Severe Inflammatory Acne: Cystic or nodular 暗瘡凹凸洞 damages deeper skin layers.
- Picking or Squeezing Pimples: Leads to skin trauma and worsens scarring.
- Repeated Acne in the Same Area: Recurring breakouts prevent proper healing.
- Genetics: Some individuals are more prone to scarring due to their skin type.
Treatment Options for Acne Scars
1. Chemical Peels (果酸換膚)
Chemical peels, especially AHA (Alpha Hydroxy Acid) and BHA (Beta Hydroxy Acid), help exfoliate the skin, unclog pores, and promote cell regeneration. While over-the-counter peels can mildly improve skin texture, medical-grade peels performed by dermatologists are more effective in stimulating collagen production.
Pros:
- Improves mild acne scars and skin tone.
- Enhances skin cell turnover.
Cons:
- Not suitable for deep scars.
- May cause redness or sensitivity.
2. Microneedling (微針療法)
Microneedling involves tiny needles creating micro-injuries in the skin, triggering collagen and elastin production. This process helps smooth out acne scars and improves skin elasticity.
Pros:
- Effective for various scar types.
- Enhances absorption of skincare products.
Cons:
- May require multiple sessions.
- Risk of infection if not done professionally.
3. Hyaluronic Acid Fillers (透明質酸填充劑)
Injectable fillers, such as Profhilo, Teosyal RHA, or Ellanse, can temporarily fill depressed acne scars, making the skin appear smoother.
Pros:
- Instant results.
- Non-invasive with minimal downtime.
Cons:
- Effects last only 6-12 months.
- May require repeated treatments.
4. Laser Therapy (激光治療)
Laser treatments, especially Pico Laser (皮秒激光), help stimulate collagen production, break down scar tissue, and improve skin texture.
Pros:
- Effective for deep scars.
- Improves overall skin tone.
Cons:
- May cause temporary redness.
- Requires multiple sessions.
5. Subcision Surgery (皮下鬆解術)
For stubborn rolling scars, subcision is a minor surgical procedure that releases the fibrous bands pulling the skin down. This allows the skin to heal naturally, improving its appearance.
Pros:
- Long-lasting results.
- Works well for deep scars.
Cons:
- Mild bruising or swelling.
- Best combined with other treatments.
Prevention Tips to Avoid Acne Scarring
- Avoid Popping Pimples: Picking at acne increases inflammation and scarring.
- Use Sunscreen Daily: UV exposure worsens hyperpigmentation and scars.
- Treat Acne Early: Preventative treatment reduces the risk of deep scarring.
- Follow a Skincare Routine: Cleanse, exfoliate, and moisturize to maintain healthy skin.
Conclusion
Acne scars can significantly impact self-confidence, but modern dermatological treatments offer effective solutions. Whether opting for chemical peels, microneedling, fillers, laser therapy, or surgery, consulting a qualified dermatologist ensures the best results. Early intervention is key to minimizing long-term skin damage and achieving a smoother, more even complexion.
