TCA Peel: What It Is, What It Does, and How to Use a TCA Peel at Home
TCA has a reputation as the "serious" peel. In-office, it can be. At home, it works differently — and that's a good thing. Here's what TCA does and how to use it safely, from a licensed aesthetician.
What Is a TCA Peel?
TCA stands for trichloroacetic acid. It's an exfoliating acid that loosens the bonds holding dead skin cells together, so built-up, pigmented and rough cells can shed.
A TCA peel uses this acid to resurface the skin — smoothing texture and evening out tone.
What Does a TCA Peel Do?
With consistent use, TCA helps:
- Fade dark spots and post-acne marks
- Smooth rough, uneven texture
- Clear congestion and clogged pores
- Brighten dull skin
- Help your serums absorb better
In-Office TCA Peels vs At-Home TCA Peels
In-office TCA peels use much higher strengths. They're designed for deep correction — and they come with visible peeling and downtime. They're done occasionally, not weekly.
At-home TCA peels use a low percentage of TCA, so they're gentle enough to use regularly. You get steady results without peeling, flaking or hiding out.
At home, stronger isn't better. If an at-home peel makes you visibly peel, it can damage your skin.
Consistency changes skin. Not chasing flakes.
Why We Pair TCA With Other Acids
Our TCA Multi-Acid Face Peel uses a low-percentage TCA (2%) alongside four other acids, so each one does its own job:
- TCA — resurfaces uneven texture
- Glycolic acid — dissolves dead skin buildup and helps lift discoloration
- Lactic acid — exfoliates while supporting hydration
- Salicylic acid — clears pore congestion
- Phytic acid — brightens and supports tone
pH matters as much as percentage. A well-balanced formula exfoliates effectively without irritating your skin — even reactive skin.
How to Use a TCA Peel at Home
Use it in the evening on clean, dry skin.
- Patch test before your first use.
- Cleanse with a gentle cleanser like our Prebiotic Gel Cleanser.
- Dermaplane or use High Frequency first (optional). Always before the peel — never after.
- Apply 1/2 a dropper of the peel to your face and neck.
- Don't rinse.
- Follow with EGF Activating Serum to support repair.
- Finish with moisturizer.
Wear SPF every morning.
How Often Can You Use a TCA Peel?
Our TCA Multi-Acid Face Peel is made to use 3–5 times a week.
Don't go over that. Overuse can compromise your skin barrier.
Use the same frequency year-round — just keep daily SPF non-negotiable.
What to Expect After a TCA Peel
- Mild tingling during application is normal and fades within minutes.
- Slight pinkness right after is normal.
- You may notice a faint glow the next morning.
- No visible peeling or flaking is needed for it to be working.
A slight tingle is normal. Burning is not. If you feel severe burning, wash it off and stop using it.
TCA Peel Results: How Long Does It Take?
After one use: brighter-looking skin and smoother texture.
Within 2–4 weeks: improved clarity, less congestion and more even tone.
With consistent use 3–5 times a week: noticeably refined texture, fewer breakouts, and more radiant, even-looking skin.
Can You Use a TCA Peel With Retinol or Dermaplaning?
Dermaplaning: yes. Dermaplane first, then apply the peel. Removing surface buildup helps the peel work more evenly.
High Frequency: yes, but always before the peel — never after.
Retinol: yes, if your skin tolerates it. Patch test first. Apply EGF between the peel and our Advanced Retinol Serum — it creates a buffer that supports recovery. Read our Peel vs Retinol guide.
Is a TCA Peel Safe?
- Our TCA peels are safe for all skin tones, lightest to darkest.
- Don't use them if you're pregnant — they contain salicylic acid.
- Skip it on open wounds or actively irritated skin, or if your skin barrier needs repair first.
- Always patch test first.
- Wear SPF every day.
