Description
Trichloroacetic acid (TCA) at 80 % concentration is a deep-strength chemical peel that selectively destroys the outer layers of the epidermis to promote rapid cell turnover and collagen remodeling. Recognized by the American Academy of Dermatology as one of the most effective deep peels available, TCA penetrates through the papillary dermis to address severe surface imperfections.
Key Benefits
Deep Exfoliation & Cell Turnover: Induces controlled coagulation of superficial skin proteins, leading to accelerated exfoliation and renewal (Journal of Cosmetic Dermatology).
Stimulates Collagen Synthesis: Triggers fibroblast activity for long-term improvement in skin firmness and reduction of fine lines (Dermatologic Surgery).
Skin Lightening & Discoloration Correction: Uniformly reduces melasma, hyperpigmentation and age spots by removing melanocyte-rich layers (International Journal of Dermatology).
Scar & Acne Treatment: Smoothes atrophic acne scars and post-inflammatory discoloration, refining texture and pore appearance.
How It Works
TCA induces a controlled chemical injury in the epidermis and superficial dermis. Protein denaturation leads to visible frosting, followed by sloughing of damaged layers within 3–7 days. The underlying dermis initiates a wound-healing cascade—upregulating collagen types I and III—for enhanced structural support and elasticity (PubMed Central).
Who Should Use This Peel
This deep-strength formulation is recommended for:
Hyperpigmentation & Melasma: For stubborn dark patches unresponsive to topical therapies.
Photo-Aging & Wrinkles: To target fine lines, rough texture and sun-damaged skin.
Acne & Acne Scars: Ideal for active comedonal acne and healing acne scars.
Scar Revision: Effective on surgical and traumatic scars requiring deep matrix remodeling.
Skin Lightening: For clients seeking dramatic skin-tone improvements beyond superficial peels.
Contraindications & Precautions
Not suitable for pregnant or nursing individuals, those with active infections (herpes simplex), keloid‐prone skin, or recent isotretinoin use within 6 months. A pre-treatment consultation and test patch are essential to assess skin tolerance and minimize risk of post-inflammatory hyperpigmentation (DermNet NZ).
Application Protocol
Preparation: Cleanse thoroughly with a pH-balanced cleanser; degrease using 70 % alcohol.
Protection: Apply petroleum jelly to sensitive areas (lips, nostrils, periocular).
Peel Application: Using a fan brush, apply one uniform coat; wait until frosting is evident (1–3 minutes).
Neutralization: Rinse with tepid water or neutralize with sodium bicarbonate solution.
Aftercare: Apply a calming serum and broad-spectrum SPF 50+ daily for 4 weeks post-treatment.
Expected Results & Timeline
Days 1–3: Erythema and firm frosting; light peeling begins.
Days 4–7: Flaking subsides; skin appears pink and supple.
Weeks 2–4: Collagen remodeling accelerates; fine lines soften and hyperpigmentation fades.
Months 1–3: Optimal firmness and tone achieved; results can last 6–12 months with proper maintenance (Clinical, Cosmetic and Investigational Dermatology).
Aftercare Recommendations
Hydration: Use ceramide-rich moisturizers to restore barrier function.
Sun Protection: Daily application of broad-spectrum SPF 50+, reapplying every 2 hours outdoors.
Avoidance: No retinoids or abrasive scrubs for 2 weeks.
Follow-Up Peels: A series of 2–3 treatments at 6-week intervals may be recommended for maximal correction.

FAQ
What skin concerns does TCA 80% Peel treat?
It effectively addresses melasma, hyperpigmentation, acne scars, fine lines, rough texture and photo-aging through deep exfoliation and collagen stimulation.
How many sessions are needed for best results?
Typically, 1–3 sessions spaced 6 weeks apart yield optimal improvement, depending on the severity of skin concerns.
Is downtime required?
Yes—expect 3–7 days of visible peeling and erythema. Most clients return to normal activities after 7–10 days.
Can I use TCA 80% Peel on sensitive skin?
A test patch and professional consultation are essential. Those with very sensitive or keloid-prone skin may require lower concentrations.
How should I care for my skin post-peel?
Maintain strict sun protection with SPF 50+, gentle hydration and avoidance of retinoids or abrasive treatments for 2 weeks.
