True to both, but don’t run for the tanning booth or apply a Colgate face mask. A particular wavelength of light has been shown to stimulate porphyrin, a chemical that eradicates the bacteria that cause acne. But while some sun exposure may help pimples get better temporarily, you can experience a rebound effect. If the skin gets dry and damaged from the sun, your body’s response is to produce oil, sun exposure can lead to bigger problems, such as premature aging and skin cancer.
As for toothpaste, it often contains menthol, which can help dry out a pimple. But other common toothpaste ingredients can irritate the skin.
