👉 Re-appearing pimples, also known as post-inflammatory hyperpigmentation (PIH), occur when the skin reacts to inflammation or injury, causing dark spots to re-emerge months or even years after the initial issue has healed. This can happen due to various factors such as acne, sun exposure, hormonal changes, or skin trauma. The dark spots are a result of increased melanin production in the affected areas, leading to uneven skin tone. Treatment often involves topical or oral medications, laser therapy, or chemical peels to reduce pigmentation and promote skin healing.
