After Treatment

Immediately After Treatment (First Few Hours)

Expected Immediate Reactions

  • Mild to moderate swelling at injection site

  • These reactions peak at 24-48 hours

Immediate Care

  1. Swelling Management:

    • Apply ice pack for 10-15 minutes (wrapped in cloth)
    • Rest for 20-30 minutes
    • Repeat ice application 3-4 times
    • Continue as needed throughout first day
  2. Pain Management:

    • Use acetaminophen (Tylenol) if needed
    • Avoid NSAIDs for first 48 hours (can increase bruising)
    • Most discomfort minimal
  3. Activity:

    • Rest for remainder of day
    • Avoid strenuous activity
    • Keep head elevated if facial/neck area treated

Days 1-3: Initial Inflammatory Phase

Expected Changes

  • Swelling increases significantly (peaks at 24-48 hours)

  • Tenderness and mild pain
  • Firmness or hardness at injection site (swollen tissue)
  • Itching may develop

Swelling Management

Activity Restrictions (Critical for Days 1-3)

  • Absolutely avoid massage or manipulation of treated area
  • Avoid strenuous exercise
  • Avoid hot environments (sauna, steam room)
  • Avoid swimming or water immersion

  • Swelling begins gradually decreasing (though still present)
  • Redness continues fading
  • Bruising continues fading
  • Firmness at injection site continues
  • Area may feel hard or lumpy (normal)
  • Possible itching or slight tenderness

Gentle Massage (Now Acceptable)

  • After day 3, gentle self-massage is beneficial
  • Light circular massage promotes healing
  • Do NOT use strong pressure or kneading
  • Avoid aggressive manipulation
  • Gentle touch only (fingertips, not palms)
  • 2-3 times daily for 5-10 minutes
  • Helps fat cell breakdown and removal
  • Promotes fluid circulation
  • Should feel gentle and soothing, not painful

Hydration and Nutrition

  • Increase water intake significantly (3-4 liters daily)
  • Helps body remove broken-down fat cells
  • Supports lymphatic drainage
  • Essential for optimal results

  • Gentle walking encouraged
  • Continue avoiding strenuous exercise
  • Avoid sauna and steam room
  • Avoid swimming
  • Can resume normal daily activities
  • Avoid activities with repetitive facial movement

Sleeping

  • Continue sleeping with head elevated
  • Sleep on back if possible
  • Reduces facial swelling
  • Improves healing process

Week 2-4: Active Fat Breakdown Phase

Key Changes

  • Swelling significantly reduces
  • Bruising continues fading
  • Firm tissue becomes softer as fat cells break down
  • Area returns to more normal appearance
  • Some asymmetry may be apparent (normal)
  • Results begin becoming visible

Important: Begin Light Exercise

  • Light exercise promotes healing and fat removal
  • Cardiovascular exercise helps process broken-down fat
  • Improves lymphatic circulation
  • Start with light walking, low-intensity activities
  • Gradually increase intensity as healing progresses
  • Full exercise routine resumable after 2 weeks if healing proceeding well

Massage Technique (Weeks 2-4)

  • Continue gentle self-massage
  • Can slightly increase pressure if comfortable
  • Promotes fat cell removal through lymphatic system
  • Helps smooth any lumpy texture
  • Continue 2-3 times daily
  • Should remain gentle and pain-free
  • Stop if experiencing pain or increased swelling

Continued Hydration

  • Maintain high water intake (3-4 liters daily)
  • Essential for removing broken-down fat
  • Supports healing and results
  • Continue for minimum 4 weeks

Medication Considerations

  • Avoid NSAIDs (can increase bruising and slow healing)
  • Continue acetaminophen only if needed
  • Avoid blood-thinning medications if possible
  • Consult doctor if on anticoagulants
  • Continue any prescribed supplements

Weeks 4-8: Visible Results Phase

Expected Results

  • Significant reduction in fat deposit visible
  • Swelling completely resolved
  • No residual bruising
  • Normal skin appearance restored
  • Contour improvement evident
  • Results continue improving

Fine Tuning

  • Some asymmetry may be apparent
  • May require second session to address
  • Usually 2-4 sessions total for optimal results

Firmness or Lumpiness

  • Completely normal during healing
