Questions

Quick answers.

Why is phenol in lip balm?

Phenol chemically exfoliates dead skin from lips, creating an instantly smooth feel. However, this strips the protective barrier, causing more peeling and dryness — which makes you reach for the lip balm again.

Is phenol in lip products dangerous?

At low concentrations it is not acutely toxic, but on lips — which are frequently licked — even small amounts are regularly ingested. Combined with its barrier-stripping action, phenol is best avoided in any lip product.

Is phenol toxic?

Yes. Phenol is classified as a hazardous substance by the EPA. It is corrosive to skin and toxic if ingested in significant amounts, causing nausea, organ damage, and potentially fatal systemic toxicity. In lip products, the concentrations are low but the regular ingestion through licking is the concern.

Does phenol cause lip balm addiction?

Phenol is one of the three main ingredients (alongside camphor and menthol) that create lip balm dependency. By chemically stripping the lip barrier, phenol ensures your lips stay dry and damaged, driving you to reapply constantly.

What are other names for phenol on labels?

Look for 'phenol,' 'carbolic acid,' 'hydroxybenzene,' or 'phenic acid' on lip product ingredient lists. Some medicated lip balms prominently feature phenol as an active ingredient for its exfoliating properties.

Does Numbrrrz contain phenol?

No. Numbrrrz lip balms contain zero phenol, camphor, or menthol. Instead of chemically exfoliating your lips, our formula of Organic Coconut Oil, Organic Jojoba Oil, Organic Beeswax, and Vitamin E supports and strengthens the natural lip barrier.
