What Is Skin Discoloration?

Skin discoloration occurs when melanin production becomes uneven—often triggered by sun exposure, inflammation, or certain skin conditions. It can show up as dark spots, post-acne marks, redness, or uneven tone. SkinCeuticals Discoloration Defense is clinically proven to visibly reduce the appearance of these concerns, with noticeable improvement in dark spots and uneven tone in as little as two weeks.
