Description
TCA 90 Peel is a concentrated dermatological solution containing 90 % pharmaceutical-grade trichloroacetic acid in a buffered base designed for professional use. Its high-purity formulation ensures predictable depth of penetration, allowing controlled resurfacing from superficial frosting to papillary dermis remodeling (StatPearls) (ResearchGate).
Mechanism of Action
Trichloroacetic acid induces immediate protein coagulation (keratocoagulation) in the epidermis and dermis, producing a visible “frost” that marks the peel depth. This irreversible denaturation of cellular proteins triggers necrosis of keratinocytes and initiates re-epithelialization and dermal remodeling (NCBI PMC) (ScienceDirect). By reaching the basal layer and upper reticular dermis, TCA 90 Peel effectively stimulates new collagen and elastin synthesis, improving skin firmness and reducing fine lines.
Indications
Melasma & Hyperpigmentation: Targets melanocyte activity to normalize uneven pigmentation (Am J Clin Dermatol).
Dark Spots & Age Spots: Accelerates melanosome turnover for a brighter complexion.
Acne & Hormonal Breakouts: Unclogs pores, reduces sebum, and minimizes whiteheads and blackheads.
Acne Scars & Scars of All Origins: Promotes scar tissue remodeling and smoothes depressed lesions.
Fine Lines & Wrinkles: Enhances collagen deposition to soften rhytides.
Sun Damage & Photoaging: Repairs actinic keratoses and diminishes sun-induced textural changes.
Benefits
Deep Exfoliation: Removes the stratum corneum and portions of the papillary dermis for dramatic renewal (ResearchGate).
Accelerated Cell Turnover: Speeds sloughing of damaged cells for a smoother, more even tone.
Collagen Stimulation: Induces neocollagenesis to restore elasticity and volume.
Targeted Lightening: Reduces melanin clusters, effectively treating melasma and post-inflammatory hyperpigmentation (Am J Clin Dermatol).
Texture Refinement: Shrinks enlarged pores and smooths rough patches.
Scar Improvement: Breaks down scar tissue and supports healthy repair.
Application Protocol
Preparation: Cleanse skin thoroughly and degrease with a 70 % alcohol wipe.
Test Frost: Apply a small amount to an inconspicuous area to gauge frosting time.
Layering: Apply 1–3 coats of TCA 90 until a uniform frost appears.
Endpoint: Observe for white frost; deeper, grey-white frost indicates medium-depth effect.
Neutralization: Not required—self-neutralizing action limits penetration (StatPearls).
Duration: Allow acid to remain for 2–5 minutes based on tolerance and desired depth.
Removal: Gently rinse with cool water and apply a soothing, hydrating post-peel balm.
Safety and Precautions
Qualified Professional Use Only: TCA 90 Peel should be administered by trained dermatologists or aestheticians.
Patch Test Recommended: Check for sensitivity, especially in Fitzpatrick skin types IV–VI.
Avoid Overlayering: Excessive coats can lead to hypopigmentation or scarring (MDEdge).
Contraindications: Active herpes simplex, open wounds, isotretinoin therapy within 6 months.
Sun Avoidance: Strict sun protection required pre- and post-treatment to prevent irregular pigmentation.
Post-Peel Care
Hydration & Barrier Repair: Use a ceramide-rich moisturizer twice daily.
Sun Protection: Broad-spectrum SPF 50+ every 2 hours for at least 4 weeks.
Gentle Cleansing: Non-foaming, pH-balanced cleanser to avoid irritation.
Avoid Exfoliants: No retinoids, AHAs, BHAs, or physical scrubs for 2 weeks.
Healing Timeline: Initial erythema and peeling for 3–7 days; resurfacing completes by day 10.
Clinical Evidence
Randomized studies confirm that medium- to high-concentration TCA peels significantly improve melasma, photoaging, and acne scarring with high patient satisfaction and low complication rates (StatPearls) (ResearchGate). Histological analysis shows increased collagen density and normalized epidermal thickness post-peel, validating its long-term remodeling effects (ScienceDirect).
FAQ
What skin concerns does TCA 90 Peel address?
TCA 90 Peel is indicated for melasma, hyperpigmentation, dark spots, acne scars, fine lines, sun damage, and texture irregularities by inducing controlled protein coagulation and renewal.
How often can I undergo a TCA 90 Peel?
Treatments are typically spaced 4–6 weeks apart. Skin should fully re-epithelialize and barrier function restore before the next session.
Is TCA 90 Peel suitable for sensitive skin?
While effective on all skin types, individuals with sensitive or darker skin tones require lower concentrations or mixed formulations to minimize risks of hypopigmentation.
What post-treatment care is required?
Apply a hydrating, barrier-repair moisturizer and SPF 50+ diligently. Avoid active exfoliants and direct sun exposure until complete healing (7–10 days).
Are there any side effects?
Common side effects include redness, peeling, and transient irritation. Improper use can lead to prolonged erythema, pigment changes, or scarring.
