Subcision can dramatically smooth rolling acne scars, but many first-time patients worry about bruising, swelling, and how long it takes to look normal again.
This detailed subcision downtime guide explains what’s expected, what’s not, and how to speed up healing safely.
At a Glance
- 💡 Bruising and swelling are normal and peak within the first 2–3 days.
- 💧 Most people look event-ready by day 7–10.
- 🏃♀️ Avoid exercise and heat exposure for one week.
- 🧊 Ice and rest help reduce puffiness and tenderness.
- 🌞 Sun protection prevents post-inflammatory pigmentation (PIH).
Why Bruising & Swelling Happen After Subcision
Subcision works by releasing fibrous bands tethering acne scars beneath the skin using a fine needle or cannula.
This mechanical release causes tiny blood vessels to break, which leads to temporary bruising and swelling.
The healing process that follows actually triggers collagen formation, which is what makes subcision so effective for smoothing rolling scars.
In short, bruising is not a complication, it’s part of the normal healing response.
Subcision Recovery Timeline
Here’s a realistic day-by-day breakdown of what to expect during Subcision downtime.
| Day | What You’ll Notice | Recommended Care |
|---|---|---|
| Day 1–2 | Redness, swelling, and small bruises. Mild soreness or tightness. | Apply a cold compress 10–15 min several times daily; keep head elevated when sleeping. |
| Day 3–5 | Bruises may darken (purple-blue); mild stiffness when smiling or washing face. | Switch to warm compresses; avoid exercise and saunas; continue gentle cleansing. |
| Day 6–10 | Swelling subsides; bruises fade to yellowish-green. Skin starts looking smoother. | Makeup allowed if skin intact; continue SPF 50+ daily; avoid harsh exfoliants. |
| Week 2+ | Most bruising gone; mild firmness may persist. Collagen remodelling begins. | Resume normal routine and light workouts; maintain hydration and sunscreen. |
| 1–3 Months | Texture gradually improves as collagen forms under the released scars. | Follow up for next session if part of multi-treatment plan. |
Post-Subcision Care Tips
- Avoid exercise, alcohol, and hot environments for at least 5–7 days.
- Sleep with your head slightly elevated to reduce swelling.
- Use gentle cleansers only; avoid scrubs or acids until skin fully settles.
- Never massage the treated area unless specifically instructed by your doctor.
- Apply broad-spectrum sunscreen SPF 50+ daily to prevent pigmentation.
These measures shorten recovery and minimise the chance of post-inflammatory hyperpigmentation.

Frequently Asked Questions
1. How long does subcision bruising last?
Bruising typically peaks by day 2–3 and fades within 7–10 days. Makeup can usually conceal any marks after the fifth day.
2. When can I exercise after subcision?
Avoid heavy workouts, running, and saunas for about a week. Gentle walking is fine after 24 hours.
3. Can I combine subcision with fillers or lasers?
Yes, but combination timing matters. Filler is sometimes added immediately post-subcision to prevent re-tethering, while lasers like CO₂ are typically spaced a few weeks apart.
4. What skincare should I use after subcision?
Stick to mild cleansers, fragrance-free moisturisers, and sunblock. Avoid retinoids, exfoliants, and vitamin C for about a week unless approved by your doctor.
5. Is it normal to feel lumps or firmness after subcision?
Yes. Small lumps or firmness indicate tissue healing beneath the skin. These usually soften within 1–2 weeks as swelling resolves.
6. When will I look ‘normal’ again?
Most people are socially comfortable around day 7–10. By the second week, bruising and swelling are minimal, and makeup covers any residual marks.
Recovery Is Temporary — Results Are Long-Term
Subcision downtime is usually under two weeks, but the collagen it triggers continues improving your skin for months.
