Yes, pimples can leave dark spots. According to research, these spots are due to the skin producing extra melanin after a pimple resolves.
Understanding Post-Inflammatory Hyperpigmentation (PIH)
When a pimple heals, the skin's natural response to inflammation can sometimes lead to post-inflammatory hyperpigmentation (PIH). Melanin, the pigment responsible for skin color, is overproduced in the affected area. This overproduction leads to the formation of dark spots.
Why Does Melanin Overproduction Occur?
The reference explains that the overproduction of melanin in a specific spot or patch on the skin surface can cause it to appear tan, brown, or dark brown. This is the primary reason why dark spots appear after a pimple heals.
Characteristics of Dark Spots from Pimples:
- Color: These spots typically appear tan, brown, or dark brown.
- Cause: They are a direct result of melanin overproduction due to skin inflammation from the pimple.
- Timing: They appear after the pimple has resolved or is in the process of healing.
Solutions:
- Over-the-counter Treatments:
- Topical creams with ingredients like retinoids, vitamin C, azelaic acid, niacinamide, or kojic acid can help fade dark spots over time.
- Professional Treatments:
- Chemical peels.
- Microdermabrasion.
- Laser therapy.
