To soothe irritation and breakouts around the mouth (perioral dermatitis), there is no need to multiply products: a minimalist approach based on 3 rules ('zero therapy,' stopping creams containing cortisone, and using very gentle skincare or fluoride-free toothpaste) is sufficient to restore healthy skin.

The idea of drastically simplifying one's skin routine, often called 'zero therapy,' is widely validated for soothing irritation and small breakouts around the mouth. A review of scientific literature published on PubMed ('Evidence-based review of perioral dermatitis therapy') confirms that completely stopping cosmetics and complex creams is the most effective method for restoring the skin's protective barrier in cases of mild discomfort. Furthermore, avoiding creams containing cortisone is crucial: observational data compiled by StatPearls show that these formulas provide ephemeral relief followed by a severe rebound effect that maintains skin irritation. The exclusion of fluoride in oral hygiene is also supported by clinical observations, as illustrated by a case study from the Australian Dental Journal, showing the disappearance of redness after discontinuing a fluoridated toothpaste. However, claiming that 'only 3 things' are enough for everyone is slightly exaggerated. For more persistent skin imbalances, a clinical synthesis published in the PubMed database ('Perioral dermatitis: still a therapeutic challenge') indicates that targeted supportive care sometimes proves essential to help the skin regain its natural balance.
