Pimple marks are a type of scarring. If the pimple marks have been formed for a long time, applying bitter melon or ointment topically cannot remove them, because bitter melon does not have any scar removal effect. If the pimple marks are fresh and just formed, you can apply drugs that promote wound healing, such as recombinant human epidermal growth factor gel, which is effective to apply. However, bitter melon application will not play an effective role in promoting wound healing, and the patient may also induce skin infection if applied improperly. Therefore, to remove acne marks, regular medications should also be applied, and if acne occurs, avoid repeated squeezing on your own.
