What Causes Dark Spots on Your Face? The Real Reasons
What causes dark spots on your face?
Dark spots form when skin produces excess melanin, usually triggered by sun exposure, hormonal changes, acne or injury, and aging. Ultraviolet light is the most common cause, which is why cumulative sun exposure leaves lasting discoloration. Genetics and certain medications can make some people more prone to them.
Understanding what causes dark spots is the first step to fading them and keeping them from coming back, so let us look at the real triggers behind uneven pigment.
Does sun exposure cause dark spots?
Yes, sun exposure is the number one cause of dark spots. Ultraviolet light signals your skin to produce extra melanin as a defense, and over years that pigment clusters into visible spots often called sun spots or age spots. Living in sunny Arizona means more cumulative exposure, so daily sun protection matters more here than in many places. Much of what people think of as aging skin is actually accumulated sun damage.
Can hormones cause dark spots?
Hormonal shifts are a major cause of a specific pattern of pigment called melasma, which often appears on the cheeks, forehead, and upper lip. Pregnancy, birth control, and hormone therapy can all trigger it, and sun exposure makes it worse. This type of pigment sits deeper and behaves differently than a simple sun spot, so it usually needs a gentler, more patient approach.
Do acne and skin injuries leave dark spots?
Yes. When a pimple, cut, or irritated patch heals, it can leave behind a flat brown or gray mark known as post-inflammatory hyperpigmentation. This is different from an acne scar, which is a change in skin texture. Picking at breakouts makes these marks darker and more likely to linger, so hands-off healing and sun protection help them fade faster.
- Post-inflammatory pigment: flat discoloration left after inflammation heals.
- True scarring: a change in texture, such as a pitted or raised mark.
Does aging make dark spots more likely?
Aging plays a role, mostly because it reflects years of sun exposure. As skin matures, pigment production becomes less even and older sun damage surfaces as spots. Genetics also influence how prone you are, and some medications can increase sensitivity to light. The reassuring part is that most of these spots respond well to brightening care and professional treatment once you protect the skin from further exposure.

Frequently Asked Questions
Are dark spots a sign of skin cancer?
Most dark spots are harmless pigment, but any spot that changes shape, color, or size, or that bleeds or will not heal, should be checked by a medical provider promptly.
Why do I keep getting new dark spots?
Ongoing sun exposure is usually the reason. Without daily broad-spectrum SPF, your skin keeps producing new pigment, so protection is essential to stop the cycle.
Can dark spots be prevented?
You cannot control genetics or hormones fully, but daily sunscreen, gentle skincare, and treating breakouts calmly greatly reduce how many dark spots form.
