Acne itself isn't permanent, but the marks and scars it leaves behind can be.
While active acne breakouts eventually subside, the inflammation they cause can lead to:
- Post-inflammatory Hyperpigmentation (PIH): These are flat, dark spots (red, brown, or even purple) that remain after a pimple heals. PIH isn't scarring, and with time, it will fade. According to the reference, this fading may take 12 months or longer.
- Acne Scarring: This involves actual damage to the skin's structure. Scars can be:
- Ice pick scars: Deep, narrow, pitted scars.
- Boxcar scars: Round or oval depressions with sharply defined edges.
- Rolling scars: Broad, shallow depressions with sloping edges.
- Hypertrophic scars: Raised, firm scars.
- Keloid scars: Raised scars that extend beyond the original wound area.
Here's a table summarizing the differences:
| Feature | Post-inflammatory Hyperpigmentation (PIH) | Acne Scarring |
|---|---|---|
| Type | Discoloration | Structural change in skin |
| Appearance | Flat, dark spots | Pitted, raised, or rolling |
| Permanence | Usually fades with time | Often permanent without treatment |
| Treatment | Topical creams, sun protection | Procedures like laser, peels |
What can you do?
- For PIH: Over-the-counter creams with ingredients like vitamin C, niacinamide, azelaic acid, and retinoids can help speed up fading. Sun protection is crucial.
- For Acne Scars: Consult a dermatologist. Treatments may include:
- Chemical peels: To remove the top layer of skin.
- Microdermabrasion: To exfoliate the skin.
- Microneedling: To stimulate collagen production.
- Laser resurfacing: To remove damaged skin layers.
- Dermal fillers: To raise depressed scars.
- Surgical excision: For severe scars.
In conclusion, while active acne is temporary, the marks and scars it leaves behind can persist. Post-inflammatory hyperpigmentation will usually fade over time, but acne scars are often permanent without professional treatment. Talk to your doctor or a dermatologist about your concerns.
