👉 Alter pimples, also known as post-inflammatory hyperpigmentation (PIH), are dark spots that appear on the skin after an acne outbreak or other inflammatory skin condition. This occurs because inflammation triggers the release of melanin, the pigment responsible for skin color, leading to an overproduction of melanin in the affected areas. As the inflammation heals and subsides, the excess melanin doesn't fade away, resulting in persistent dark spots. Factors like sun exposure, hormonal changes, and genetics can exacerbate PIH, making it more noticeable. Treatments for alter pimples often include topical creams with ingredients like niacinamide, vitamin C, or retinoids, and in some cases, professional skin treatments such as chemical peels or laser therapy.
