Dark Spots

Dark Spots — areas of localized hyperpigmentation where skin appears noticeably darker than the surrounding complexion, often as a result of excess melanin production. They commonly arise from sun exposure, healing acne or inflammation, and hormonal shifts, and can vary in size and shade. The umbrella term covers several types, including post-inflammatory hyperpigmentation and sun-related spots.

Key points

• Dark spots form when melanocytes deposit extra melanin in response to triggers such as UV light, inflammation, or hormones.
• Post-inflammatory hyperpigmentation is a frequent cause and often follows acne, especially in medium-to-deep skin tones.
• Consistent sunscreen use is essential, as unprotected sun exposure can deepen existing spots and slow their fading.
• Topical ingredients like vitamin C, niacinamide, azelaic acid, and retinoids are widely used to help fade the appearance of dark spots over time.

Frequently asked

Why do dark spots appear after acne?

Inflammation from a breakout can stimulate extra melanin production as the skin heals, leaving a flat darkened mark known as post-inflammatory hyperpigmentation.

Can dark spots fade without treatment?

Some dark spots fade on their own over months, but sun protection and targeted ingredients can support and speed the evening of tone.
