The Spot Pill is an oral medication that treats hyperpigmentation on the face by targeting specific enzymes. These enzymes are most commonly found in facial hyperpigmentation, meaning dark spots on the body may not be affected.
The Skin pill is an oral longevity treatment. This medication is not expected to treat existing hyperpigmentation, but does help protect against UV damage. While this can also help create a brighter and more even skin tone, this is closer to a glowing effect, rather than dark spot removal.
