Uneven Skin Tone
An uneven skin tone, called hyperpigmentation, is irregular darkening of the skin. The cause: overproduction of melanin, the pigment responsible for skin and hair color. The resulting dark patches and spots are typically perceived as "aged skin"
Post-Inflammatory Hyperpigmentation: Acne scars are one of the most common causes of hyperpigmentation in patients. Post-inflammatory hyperpigmentation describes dark spots that are sometimes left behind after an inflammatory wound on the skin has healed, often caused by acne breakouts or from picking at acne lesions (causing scars).
A scar forms caused on your skin when your body heals an injury. To get a scar, the wound has to go deep enough to injure the inner layers of your skin, the dermis.
When we injure the deeper layers of our skin, cells make collagen to repair the wound. Because your body makes this collagen quickly, it’s thicker and less flexible than the rest of your skin. The thicker, less flexible tissue is a scar.
Dark spots caused by post-inflammatory hyperpigmentation are often flat, dark brown, red, gray, black, pink, or purple. When the skin heals from the inflammation, excess melanin is produced to aid the body in its recovery. As a result, the affected area is discolored—which is usually permanent, though skin discolorations can fade over time.
This type of discoloration can also appear after cosmetic treatments such as chemical peels, dermabrasion, or laser treatments—usually as a result of poor, unprofessional practices or on candidates with darker skin tones unsuitable for these types of procedures.
