Glossary entry

Camphor.

Definition

What it means.

A waxy substance with a strong aroma used in some medicated lip balms like Carmex and Blistex. Camphor creates a cooling, tingling sensation that feels soothing but actually irritates lip tissue, contributing to the lip balm dependency cycle. Dermatologists frequently recommend avoiding camphor in lip products for people with chronic lip dryness.

Menthol

An organic compound found naturally in mint plants that produces a cooling sensation on skin. While menthol in small amounts (like in Numbrrrz Peppermint's organic peppermint essential oil) can provide pleasant stimulation, the synthetic menthol used in high concentrations in medicated lip balms can irritate lip tissue and worsen dryness over time.

Petroleum (Petrolatum)

A semi-solid mixture of hydrocarbons derived from crude oil refining. Commonly used in conventional lip balms as an occlusive barrier. While effective at preventing moisture loss, petroleum does not add moisture — it only traps what is already present. It can also prevent skin from breathing naturally and may contain trace contaminants. Numbrrrz does not use petroleum in any of its products.

Cheilitis

The medical term for inflammation of the lips. Cheilitis can have several causes and may involve redness, swelling, cracking, or peeling. Consult a healthcare professional for diagnosis and treatment. Numbrrrz is a cosmetic moisturizer, not a treatment or prevention product for cheilitis.
