What Causes Dark Spots and Uneven Skin Tone?
Dark spots form when your skin produces excess melanin, the pigment responsible for color. Triggers include:
- Sun exposure – UV rays stimulate melanin overproduction, causing freckles, sunspots, and overall darkening.
- Hormonal changes – Conditions like melasma often arise during pregnancy, with birth control, or menopause.
- Post-inflammatory hyperpigmentation (PIH) – Dark marks left behind after acne, eczema, or injury.
- Aging – Slower skin turnover and accumulated sun damage can make pigmentation more noticeable.
- Certain medications or skin care reactions – Some drugs or harsh treatments can cause pigmentation changes.
Prevention Tip: Use SPF 30+ every day, even indoors. UV rays penetrate windows and can undo weeks of serum use.
