Zero Therapy for Perioral Dermatitis
Zero therapy is one of the most widely recommended approaches in the perioral dermatitis community. The premise is simple: stop applying all topical products to the affected area and let the skin reset on its own.
What is zero therapy?
Zero therapy (also called “zero products” or the “nothing approach”) means completely stopping all topical products on the perioral area. This includes moisturizer, sunscreen, makeup, serum — everything.
The logic: most PD is driven or maintained by ingredients in everyday products (SLS, fragrance, occlusives, steroids). By removing everything, you eliminate all potential triggers simultaneously rather than spending months swapping products one by one.
The protocol
Stop all topical products on the affected area
No moisturizer, no SPF, no serum, no makeup, no prescription topicals. For the chin and perioral area only — continue your regular routine elsewhere if needed.
Switch your toothpaste
Use an SLS-free, fluoride-free, and mint-free toothpaste. This is a prerequisite — toothpaste residue spreads to the perioral area on every use.
Stop all steroid creams immediately
If you've been applying hydrocortisone or any topical steroid — stop. Steroids are one of the primary causes of PD and significantly worsen it with continued use.
Expect an initial purge
Most people experience an initial flare 1–3 weeks in as the skin adjusts. This is normal. The flare is temporary and typically resolves as you continue.
Wait 8–12 weeks
Many people see significant improvement at 4–6 weeks. Full clearance often takes 8–12 weeks. Results vary depending on how long PD has been active and what was triggering it.
Reintroduce products slowly
Once clear, reintroduce one product at a time, waiting 2 weeks between each addition. If a flare returns, you've identified the trigger.
What to expect
⚠️ The initial flare is normal
Week 1–3 can look worse before it looks better. The skin is adjusting to the absence of products and purging. Most people who push through this phase see consistent improvement from week 4 onward. The community consensus is: do not give up during the initial flare.
✅ What most people report
- → Redness reduces significantly around week 4–6
- → Bumps flatten and dry out before clearing
- → Skin feels drier initially, then self-regulates
- → Full clearance typically by week 8–12
The one product most people keep using
Hypochlorous acid spray — the r/PerioralDermatitis wiki specifically recommends spraying hypochlorous acid (HOCl) on the affected area multiple times a day. It is antibacterial, anti-inflammatory, and disrupts biofilms without causing irritation. Many people use it alongside zero therapy.
