Chemical exfoliation has become a game-changer in skincare, helping to reveal smoother skin. Trichloroacetic acid (TCA) and glycolic peel pads are two powerful exfoliants that can improve skin texture, minimize fine lines, and brighten your complexion. However, using them incorrectly can lead to irritation, redness, or even damage. To ensure you get the best results, it's essential to understand how to use these potent acids safely and effectively. Dr. Richard Bottiglione, a board-certified dermatologist with over 50 years of experience, has treated thousands of patients using chemical peels and acid-based skincare. He explains, "Trichloroacetic acid is an acid that we have used for about 100 years in dermatology on the face mostly." With his expertise, he has developed Dermatologist’s Choice TCA and glycolic peel pads to help people achieve professional-level results at home. In this guide, we’ll explore the most common mistakes people make when using TCA and glycolic peel pads—and how to avoid them.
1. Choosing the Wrong Strength for Your Skin Type
Dr. Bottiglione explains, "TCA acid is another level above alpha hydroxy acid, glycolic acid. It’s the next strength up, but not quite as strong as phenol acid." That means it’s essential to choose a concentration that matches your skin’s tolerance. Beginners should start with a milder formula like pH Balanced TCA Toning Pads before moving to stronger Glycolic TCA Peel Pads.
2. Skipping a Patch Test
While Dr. Bottiglione notes that "No special test has to be done if you’re using something mild," those with sensitive skin should always test a small amount on their cheek before full application. This step can help prevent unexpected reactions.
3. Overusing (or Underusing) Peel Pads
When it comes to exfoliating acids, more doesn’t always mean better. Dr. Bottiglione recommends using peel pads two to three times a week but emphasizes that how often you can use them really depends on how dry or sensitive your skin is. Overdoing it can lead to irritation, redness, and sensitivity—but that doesn’t mean you need to give up acids altogether. Instead, it’s about learning how your skin responds and adjusting accordingly. Trial and error plays a big role in figuring out your skin’s tolerance. If you experience irritation, simply scale back to once a week and be sure to follow up with a gentle, hydrating moisturizer.
4. Not Prepping Your Skin Properly
For optimal results, use peel pads on clean, dry skin. Dr. Bottiglione recommends pairing them with pH Balanced Cleanser to remove excess oil and dirt before applying an acid-based treatment.
5. Neglecting Moisturizer After Application
Exfoliation removes dead skin cells, but it’s crucial to follow up with hydration. After using peel pads, apply a soothing moisturizer to maintain your skin’s barrier and prevent excessive dryness.
6. Skipping Sunscreen
One of the most important (and most overlooked) steps in any skincare routine is daily sunscreen application. Dr. Bottiglione, who has been performing TCA peels for decades in sunny Arizona, shares that his patients aren’t more likely to get a sunburn after a peel than at any other time; however, you should be smart about sun protection, regardless of the season or your skincare routine. Always apply a broad-spectrum sunscreen with SPF 30 or higher every morning, and reapply throughout the day if you’re spending time outdoors. Consistent protection is key to maintaining healthy, radiant skin year-round.
7. Using Acids Too Close to a Big Event
Planning a chemical peel right before an important occasion? Dr. Bottiglione advises, "If you have a wedding or big event coming up, it might not be best to do the stronger acids a couple of days before." Stick to a milder acid like glycolic or a lower-strength TCA peel pad to avoid redness or peeling.
8. Not Understanding Your Skin’s Tolerance
Dr. Bottiglione notes, "Anyone can use these acids, but you may have to modify the strength. Some people can use it once a week, others once a month." Listen to your skin and adjust the frequency accordingly. It's best to start with application once a week and then build up to daily application if your skin tolerates it. Best to start with the mildest pH Balanced TCA Toning Pads.

9. Applying Too Much Pressure
When using peel pads, a gentle swipe is enough. Rubbing aggressively can lead to irritation, especially when using higher-strength acids.
10. Buying From an Unreliable Source
Not all acids are created equal. Dr. Bottiglione stresses the importance of using high-quality, clinically tested formulations: "You should buy the trichloroacetic acid from a reputable place so you get the right concentration and pure TCA acid like in our Dermatologist's Choice products."
