Cosmetic Complications and Management

Dermal Fillers - Puffy Problems & Pinpoint Fixes

• Early Complications (<2 wks):
  • Common: Erythema, edema, pain, bruising (resolve spontaneously).
  • Tyndall effect: Bluish hue with superficial Hyaluronic Acid (HA) fillers.
  • Nodules: Inflammatory or non-inflammatory lumps.
  • ⚠️ Vascular Occlusion (VO): Critical! Signs: immediate pain, blanching, livedo reticularis, dusky discoloration. EMERGENCY!
• Delayed Complications (>2 wks):
  • Granulomas (foreign body reaction), biofilms (persistent infection), filler migration.
• Management Highlights:
  • Tyndall effect: Hyaluronidase (10-30 IU).
  • Nodules (HA): Massage; if persistent, hyaluronidase.
  • Granulomas: Intralesional steroids (e.g., Triamcinolone 5-10 mg/mL), 5-FU.
  • VO (HA Fillers): 📌 H.A.R.M.E.D. protocol: Hyaluronidase (high dose, e.g., 150-1500 IU, repeat until reperfusion), Aspirin (325 mg), Refer (ophthalmology if vision changes), Massage, Elevate (controversial), Dilators (topical nitroglycerin). Warm compress.

    ⭐ Immediate, aggressive high-dose hyaluronidase is the cornerstone for managing HA filler-induced vascular occlusion to prevent tissue necrosis or blindness.

Neurotoxins - Frozen Frowns & Fixes

BoNT blocks ACh release → muscle paralysis. Effects: 3-4 months.

• Common Complications & Management:
  • Overcorrection (Frozen look, Spock brow):
    • Spock brow: Micro-BoNT to lateral frontalis.
  • Undercorrection/Asymmetry: Touch-up after 2 weeks.
  • Ptosis (eyelid droop):
    • Common significant issue.
    • Rx: Apraclonidine 0.5% / Phenylephrine 2.5% drops (Müller's muscle).
    • Resolves spontaneously.
  • Diffusion: Diplopia, dysphagia (rare, supportive).
  • Injection site: Pain, bruising (cold compress), headache.
• Prevention:
  • Precise anatomy, dose, placement.
  • Avoid levator palpebrae proximity.

⭐ Ptosis post-glabellar BoNT: due to levator palpebrae superioris diffusion. Rx: apraclonidine 0.5% drops.

Energy Devices - Zap Traps & Zap-Backs

• Common Complications (Zap Traps) & Management (Zap-Backs):
  • Thermal Injury (Burns): Superficial/deep. Manage with immediate cooling, emollients, topical antibiotics (e.g., mupirocin), non-adherent dressings.
  • Pigmentary Changes:
    • Post-Inflammatory Hyperpigmentation (PIH): Frequent in Indian skin (Fitzpatrick types IV-VI). Strict sun protection (SPF >30), hydroquinone 2-4%, topical retinoids, azelaic acid, low-fluence Q-switched Nd:YAG laser.
    • Hypopigmentation: Often delayed, challenging. Options: topical corticosteroids (if inflammatory), excimer laser (308 nm), targeted phototherapy, microneedling, medical tattooing (camouflage).
  • Scarring (Atrophic, Hypertrophic): Silicone gel/sheets, intralesional triamcinolone acetonide (10-40 mg/mL), fractional lasers (ablative/non-ablative), pulsed dye laser for erythematous scars.
  • Infection: Herpes simplex virus (HSV) reactivation common with perioral/full-face resurfacing. Prophylactic antivirals (e.g., acyclovir 400 mg BID) starting 1 day prior.
  • Ocular Injury: Corneal/retinal damage. Mandatory, wavelength-specific eye protection for patient & operator.
  • Paradoxical Hypertrichosis: ↑ finer hair growth post-laser hair removal. Adjust fluence, spot size, cooling; consider longer pulse durations.

⭐ For Fitzpatrick skin types IV-VI, always prioritize longer wavelengths (e.g., Nd:YAG 1064 nm, Diode 810 nm) and effective epidermal cooling during laser procedures to minimize risk of PIH and burns.

Peels & Needles - Surface Setbacks & Solutions

• Chemical Peels:
  • Complications: PIH (most common, esp. darker skin), infection (HSV reactivation), scarring (esp. deep peels), persistent erythema, allergic contact dermatitis, milia.
  • Management: Strict photoprotection (PIH), prophylactic antivirals (HSV risk), topical steroids/silicone (scars), gentle cleansers.
• Microneedling:
  • Complications: Common: transient erythema, edema, petechiae. Rare: infection (bacterial/fungal), granulomas, PIH, tram-track scarring (improper technique/pressure).
  • Management: Cool compresses, topical antibiotics (if infection), sun avoidance, proper technique.

⭐ Prophylactic acyclovir is recommended for patients with a history of herpes simplex undergoing facial peels to prevent reactivation.

High‑Yield Points - ⚡ Biggest Takeaways

• Filler vascular occlusion: EMERGENCY. Management: High-dose hyaluronidase, warm compress, massage.
• Botulinum toxin: Eyelid ptosis (most common), eyebrow asymmetry. Management: Apraclonidine drops for ptosis.
• Lasers/Chemical Peels: Post-Inflammatory Hyperpigmentation (PIH) especially in darker skin types (Fitzpatrick IV-VI).
• Infections: Herpetic reactivation (prophylaxis for ablative procedures), bacterial cellulitis.
• Granulomas/Nodules: Delayed hypersensitivity to fillers; manage with IL steroids, 5-FU, or excision.
• Tyndall Effect: Bluish discoloration from superficial HA filler placement; treat with hyaluronidase.
