What Actually Causes Dark Spots?
Dark spots, medically known as hyperpigmentation, can stem from several distinct underlying causes, each responding differently to treatment.
Understanding the underlying cause matters for choosing the right approach, and for knowing when to see a dermatologist rather than relying on skincare alone.
Sun-induced pigmentation
Cumulative UV exposure is the most common cause of dark spots, sometimes called sunspots or age spots, particularly on the face, hands and chest. Daily sunscreen is both the best prevention and an essential complement to any brightening product.
Post-inflammatory hyperpigmentation
Dark marks that linger after acne, cuts, or skin irritation heals are extremely common, especially in people with more melanin-rich skin tones. These often fade gradually on their own but can take months.
Melasma
A hormonally-influenced condition causing larger patches of darker skin, often triggered by pregnancy, birth control or sun exposure. Melasma is notoriously difficult to treat and often requires a dermatologist's guidance, as some over-the-counter approaches can worsen it.
Age-related changes
Skin's natural pigment-producing cells become less evenly distributed with age and cumulative sun exposure, contributing to isolated dark spots distinct from broader melasma patterns.
Why the distinction matters
Applying this to Illuderma
Formulas like Illuderma are designed to support an even-looking tone for general, sun-exposure-related or age-related dark spots over time. Melasma and any changing or unusual spots deserve a dermatologist's evaluation first, not a serum alone.
