What happens after your IPL session matters as much as the treatment itself. This guide covers the normal healing process, what to do and avoid at each stage, and how to prevent the one complication that undoes results — post-inflammatory hyperpigmentation (PIH).

The “Coffee Ground” Effect — What’s Normal
IPL targets the melanin in pigmented spots, causing it to fragment and rise to the surface. The treated spots will darken noticeably — sometimes significantly — in the first 1–5 days. This is called the coffee ground effect or MENDS (Microscopic Epidermal Necrotic Debris), and it means the treatment worked.
Days 1–2
Spots appear darker and more defined. Mild redness and warmth in the treated area. This is expected.
Days 3–5
Spots take on a dark, slightly raised, coffee-ground appearance. You will want to pick at them. Don’t.
Days 5–14
Crusts begin to flake off naturally, often in the shower. Facial pigmentation typically sheds by day 10; body areas (chest, hands, décolletage) take up to 3 weeks — this is normal biology, not a treatment problem.
Never pick, scratch, or scrub the crusts
Premature removal causes scarring, infection, and post-inflammatory hyperpigmentation — new dark marks that are harder to treat than the original pigmentation. Let them shed naturally.
Immediate Aftercare (First 48 Hours)
Do:
- Cool compress or chilled aloe vera gel to soothe (no ice directly on skin)
- Lukewarm water only — no hot showers or baths
- Gentle fragrance-free cleanser, pat dry
- Mineral-based makeup only if covering is needed (no liquid foundations)
- SPF 50+ physical sunscreen on all treated areas
Avoid for 48 hours:
- Hot showers, saunas, steam rooms, infrared sauna
- Swimming (chlorine, salt water)
- Intense exercise or excessive sweating
- Fragranced products, fake tan, perfume on treated skin
- Waxing, threading, or hair removal on treated areas
Products: What to Use and Avoid
Safe (Days 1–7):
- Gentle pH-balanced cleanser (fragrance-free)
- Ceramide-rich moisturiser
- Hyaluronic acid serum
- Aloe vera gel (pure, no alcohol)
- Physical SPF 50+ (zinc oxide or titanium dioxide)
Avoid for 7–14 days:
- Retinol / retinoids — resume after day 10–14
- AHA / BHA acids (glycolic, lactic, salicylic) — resume after day 10–14
- High-strength Vitamin C — resume after day 7
- Physical scrubs, exfoliating brushes, or tools
- Benzoyl peroxide
- Fragranced products
Why physical sunscreen?
Mineral sunscreens (zinc oxide, titanium dioxide) sit on the skin surface and reflect UV — less irritating on healing skin than chemical sunscreens, which absorb into the epidermis. Use mineral for the first 2 weeks, then return to your preferred formula.
Preventing Post-Inflammatory Hyperpigmentation (PIH)
PIH is new pigmentation triggered by inflammation or injury — it can be darker and more stubborn than what you originally treated. It’s the main complication after IPL and almost always preventable.
How to prevent it:
- Don’t pick — the #1 cause of PIH
- SPF 50+ daily — UV is the #2 cause; even incidental exposure triggers melanocyte activity
- Avoid heat — hot showers, saunas, and hot yoga for 2 weeks
- Don’t introduce irritating actives too soon — wait the full 10–14 days
- Fitzpatrick III–IV skin: consider a tyrosinase inhibitor (niacinamide, Vitamin C, tranexamic acid) for 2 weeks before your next treatment session to quieten melanocyte activity — discuss with Zeda
Healing Timeline
| Stage | Face | Body (chest, hands, décolletage) |
|---|---|---|
| Initial darkening | Days 1–2 | Days 1–2 |
| Coffee ground peak | Days 3–5 | Days 3–7 |
| Shedding begins | Days 5–7 | Days 7–14 |
| Fully shed | Days 7–10 | Days 14–21 |
| Final result visible | Week 4 | Week 4–6 |
Body skin has a slower cell turnover cycle (40–60 days vs ~28 days for face) — longer shedding time is normal biology.
Results by session:
- After 1 treatment: 40–60% improvement
- After 3 treatments: 70–85% improvement
- After 5 treatments: 85–95% improvement
- Maintenance: touch-up every 12–24 months

Frequently Asked Questions
My spots are darker after treatment — did something go wrong?
No. Darkening is a sign the treatment worked. The fragmented melanin is rising to the surface to be shed. It will look worse before it looks better — that’s the process.
I accidentally picked a crust. What now?
Stop. Apply a thin layer of antibacterial ointment, keep the area clean, and be strict with SPF 50+. Watch for PIH (new dark mark) over the next 2–4 weeks. If it develops, contact us — tranexamic acid or Vitamin C can help minimise it.
My chest/hand pigmentation is taking longer than my face. Is that normal?
Yes — completely normal. Body skin renews more slowly than facial skin. Expect 2–3 weeks for body areas to fully shed versus 7–10 days for the face.
When can I have my next session?
Minimum 4 weeks between treatments — typically 4–6 weeks is optimal. This allows complete healing and collagen remodelling before the next session.
I have an event in 2 weeks. Should I book IPL now?
No. The coffee ground phase (Days 3–7) makes spots more visible before they clear. Book IPL at least 3 weeks before any event you need clear skin for.
