Hyperpigmentation Treatment in Campbell

Hyperpigmentation is a common skin condition where patches of skin become darker than the surrounding skin due to excess melanin production. It can affect people of any skin type and appear anywhere on the body. Common forms include sun spots (solar lentigines) from UV exposure, post-inflammatory hyperpigmentation (PIH) from skin injury or inflammation, and melasma from hormonal changes. While usually harmless, hyperpigmentation can be cosmetically concerning. Treatment depends on the underlying cause and may include topical lightening agents, chemical peels, and laser therapy.

At a Glance

Hyperpigmentation occurs when skin cells produce excess melanin, causing darker patches^[1]

Post-inflammatory hyperpigmentation commonly accompanies acne, especially in darker skin tones^[2]

Most dark spots will fade over time after the underlying cause is treated, though it may take many months^[1]

Treatments can take several months to a year to show noticeable improvement^[2]

Frequently Asked Questions

Hyperpigmentation is a common skin condition where patches become darker than surrounding skin due to excess melanin production. Common types include sun spots (age spots), post-inflammatory hyperpigmentation from acne or injury, and melasma from hormones. While usually harmless, it can be cosmetically concerning.
Dark spots develop when skin cells produce excess melanin. Common causes include sun exposure (creating age spots), skin injury or inflammation like acne (post- inflammatory hyperpigmentation), hormonal changes (melasma), certain medications, and genetic factors. The cause determines the best treatment approach.
See a dermatologist if dark spots concern you cosmetically, you notice new or changing pigmented areas, spots developed after acne or skin injury, or you want professional treatment options. A dermatologist can determine the type of hyperpigmentation and recommend appropriate treatments.
Treatment starts with daily sunscreen to prevent worsening. Options include topical lightening agents (hydroquinone, vitamin C, azelaic acid, retinoids), chemical peels, and laser treatments. Treatment may take months to show results. The underlying cause must also be addressed.
Some dark spots, especially post-inflammatory hyperpigmentation from acne or injury, may fade over time once the cause is treated. However, this can take months to years. Sun spots often don't fade without treatment. Consistent sun protection helps prevent new spots and speeds fading.
Prevention centers on sun protection: use broad-spectrum SPF 30+ sunscreen daily, reapply every two hours outdoors, wear protective clothing and hats, and avoid tanning beds. Treating underlying conditions like rashes or acne promptly helps prevent post-inflammatory hyperpigmentation. Avoid injuring and picking at skin.
