Oman today_ Many people still use toothpaste to treat pimples because the drying sensation it creates on the skin is mistakenly interpreted as having a pimple-drying effect. In the past, some toothpastes contained triclosan, an antibacterial agent that could somewhat reduce surface bacteria on the skin. However, since 2016, this compound has been removed from most personal care products due to its potential negative effects on hormones, contribution to microbial resistance, and disruption of the skin’s natural balance.
In addition, ingredients such as baking soda, hydrogen peroxide, menthol, alcohol, sodium lauryl sulfate, and fluoride can create a feeling of coolness, dryness, or mild burning, which is often misinterpreted as a therapeutic effect. Baking soda, by altering the skin’s pH, can weaken its protective barrier, leading to dryness, inflammation, and increased vulnerability. Hydrogen peroxide, although antibacterial, can damage healthy skin cells and disrupt the natural healing process. Menthol and peppermint extract provide a cooling sensation but may trigger irritation or allergic reactions in sensitive skin. Sodium lauryl sulfate strips natural oils from the skin, weakening its protective barrier, and fluoride may cause sensitivity and inflammation in some individuals.
Research and dermatologists’ opinions indicate that using toothpaste on pimples is not only ineffective but can also cause irritation, excessive dryness, increased oil production, disruption of the skin’s microbiome, and the formation of dark spots or scars. Reputable organizations and sources, including the American Academy of Dermatology, Healthline, Curology, and Cleveland Clinic, emphasize that there is no clinical evidence supporting toothpaste as a treatment for acne, and its use may produce the opposite effect.
In summary, toothpaste is formulated for teeth, not facial skin. Applying it topically can be more harmful than beneficial, potentially leading to a range of skin problems rather than improving acne.
