Thank you for your question. The best thing to do would be to make an appointment with a board certified dermatologist to evaluate the lesion to see if it is something that would need to be removed and biopsied. If it is just a freckled then it can be easily treated with an IPL. The IPL can be used to spot treat and is a safe and effective non scarring method to effectively remove scars and sunspots.
yes, it is possible to remove one freckle from the nose without scarring. There are many different options to do this. It can range from chemical peels, to laser based treatments, to radiofrequency to remove a freckle. It would be helpful to see a photograph to determine what kind of freckle it is as well as the underlying skin type. There's always a risk from any procedure of potentially scarring however the risk is small and minimal especially when performed by an experienced provider and technology.
