Study Notes
Trichloroacetic Acid (TCA)
What is TCA?
- A derivative of acetic acid, used as a peeling agent in chemical peels
- A strong exfoliant, effective in removing dead skin cells and promoting cell turnover
Uses of TCA:
- Chemical peels for skin rejuvenation and skin imperfections (e.g., fine lines, wrinkles, hyperpigmentation)
- Treatment of skin conditions (e.g., acne, rosacea, melasma)
- Hair removal and skin depilatory
- Medical treatments (e.g., removal of warts, moles)
Concentrations of TCA:
- Light peels: 10-15% TCA, suitable for sensitive skin
- Medium peels: 15-25% TCA, for moderate skin imperfections
- Deep peels: 25-50% TCA, for severe skin imperfections and deep scarring
Benefits of TCA:
- Improves skin texture and tone
- Reduces appearance of fine lines and wrinkles
- Fades age spots and hyperpigmentation
- Unclogs pores and reduces acne
- Stimulates collagen production
Side Effects and Precautions:
- Skin irritation, redness, and itching
- Post-inflammatory hyperpigmentation (PIH) in darker skin types
- Contraindications: pregnancy, breastfeeding, active skin infections, and rosacea
- Pre-treatment preparation: avoid sun exposure, waxing, and exfoliating 1-2 weeks prior
