Question: how long does it take for an ingrown pimple to go away?
Answer: Acne on the back may be persistent. With treatment, people may see an improvement in 6–8 weeks, while complete healing may take 3–4 months. Sometimes, what appears to be a pimple is a different kind of blemish. Ingrown hairs, for example, can cause red, swollen bumps that tend to form after shaving the face or legs.
