Episode: Barrier is the Boss: The Foundation of Acne Healing
Host: Tessa Zolli
Date: August 22, 2025

Overview

In this episode, licensed esthetician and acne expert Tessa Zolli explores the often-overlooked foundation of any acne healing journey: the skin barrier. Tess shares her personal and professional insights into why barrier repair and resilience are crucial for both clearing acne and ensuring long-term skin health. She provides actionable guidance for estheticians, skin-care professionals, and acne sufferers, emphasizing a gentle, progressive approach and busting common myths about what “works” in acne care.

Key Discussion Points & Insights

1. The Under-Discussed Challenge in Acne Treatment

• Main premise: The hardest part of acne treatment isn’t just clearing breakouts, but conditioning a damaged skin barrier—something clients typically underestimate.
  • “[Clients] have no idea that they're having an even harder time clearing their acne because their skin barrier is damaged.” (04:36)
• Balance required: The goal is to heal the skin and reduce inflammation while still addressing client expectations for clear skin, which is tricky with a compromised barrier.

2. Common Causes of Barrier Damage

Tess details typical factors affecting skin barrier integrity:

• Prescription Acne Medications:
  Many clients have used strong actives (like Adapalene, tretinoin, clindamycin) without proper barrier preparation or guidance.
  • “With a prescription, you're typically not going to have a whole bunch of peptides, anti-inflammatories, antioxidants, ceramides, healing ingredients...” (06:00)
• Harsh Climates & Travel:
  Frequent exposure to extreme dry, humid, or constantly changing climates stresses the skin.
• Overuse & Misuse of OTC Products:
  Poorly formulated products, or people "playing chemist" and overusing actives like salicylic acid or benzoyl peroxide, harm more than help if not used correctly.
  • “When they're reading a universal direction for how much they should use...this is where problems arise.” (09:47)
• Over-Scrubbing:
  Physical scrubs with rough particles (such as coffee scrubs or St. Ives) can create micro-tears and significant barrier breakdown.
• Sweat, Pools, Saunas, Sun, and Other Stressors:
  Lingering sweat, chlorine, excessive heat exposure, and especially sunscreen neglect are all cited as common irritants—sunscreen is non-negotiable for anyone using acne actives.
  • “They're not going to be able to use their acne treatments long-term if they are not using sunscreen.” (13:39)
• Lifestyle & Internal Factors:
  Shaving, improper dermaplaning, peels/microneedling on unprepared skin, and diet/nutrient deficiencies all play a role.

3. Vicious Cycle: Over-Treatment and Barrier Breakdown

• Many clients fall into a cycle: more breakouts lead to more aggressive products, which further damage the barrier, leading to more inflammation and further breakouts.
• Slowing down and focusing on barrier conditioning during the early stages of an acne program is essential, even if it means slower initial results.
  • “If you push too far then you have to stop everything...That's when we can lose progress.” (16:43)
• Tess’s program prioritizes a "gentle push," allowing time for acclimation.

4. The Art of Progressive Acne Programs

• The “best trainer” analogy: a great esthetician, like a great fitness coach, starts by understanding the client’s history and current capacity—not by jumping into the most intense regimen possible.
  • “The really good estheticians will really value building trust. And so that starts with rebuilding that skin barrier first.” (19:27)
• Regular monitoring and personalization of product type, frequency, and intensity are vital.
• A well-designed routine must always balance actives with hydrators and barrier-supporting products.
  • “Basically calm skin is clear skin.” (20:48)
• Tess recommends hydrating masks and moisture-focused sunscreens, especially during barrier repair.

5. Real-Life Example: Maggie McDonald

• Tess shares a client success story with lifestyle influencer Maggie McDonald, whose skin barrier was naturally strong, making acne clearing relatively easy.
• By contrast, clients with years of barrier compromise or post-Accutane sensitivity require much more cautious, gradual approaches.
  • “Her skin is unusually strong. She had a really resilient barrier and that just made my job so much easier.” (26:30)
• The importance of daily self-assessment for signs of over-treatment is emphasized.

6. Acclimation: A Necessary and Manageable Phase

• Some temporary mild dryness or redness is normal during the early use of actives; severe or prolonged discomfort is not.
  • “When you start to experience sensation that lasts more than 10 minutes, or you feel your face is on fire...these are all signs that we are pushing it too far.” (19:01)
• Acclimation should be akin to muscle soreness during a new fitness regime: a sign of progress, but never pushing into pain or injury.

7. Mindset and Motivation

• Tess relates her own struggle with acne and how strengthening her barrier with the “scary” actives—when used appropriately—ultimately healed her skin.
  • “It's not that my skin was sensitive, it was that it didn't have the proper ingredients, routine or stimulus to heal.” (32:27)
  • “If we show our skin the love it deserves, it will love us back.” (32:59)
• Being gentle, patient, and kind to yourself is as important as following the right routine.

• Every client’s journey is unique. Observing, listening, and individualizing care is key—there’s no universal prescription for everyone.
• Temporary symptoms like mild dryness are expected; persistent stinging, burning, or pain are red flags.
• Consistency, protection (especially sunscreen!), and progressive acclimation are all foundational.
• A healthy skin barrier is not just a side benefit but the prerequisite to both clear skin and successful acne treatment.
