What should you know about collagen for dark spots?

Melasma often appears as recurring facial patches influenced by light and hormones. Post-inflammatory hyperpigmentation can follow acne, eczema, or injury. Sun spots tend to occur on exposed skin, while tinea versicolor can create lighter or darker patches with fine scale. Compare these possibilities with [Dark Patches On Skin](/symptoms/dark-patches-on-skin/), [Melasma](/conditions/melasma/), [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/), [Sun Spots](/conditions/sun-spots/), and [Tinea Versicolor](/conditions/tinea-versicolor/).

Use daily broad-spectrum sun protection, avoid picking or harsh scrubbing, and treat active inflammation with professional guidance. Depending on the diagnosis, a dermatologist may discuss a chemical peel, skin brightening treatment, or picosecond laser treatment. These options have different effects and risks, particularly for skin that marks easily, so diagnosis should come first.

Arrange an assessment for a spot that is new, rapidly changing, bleeding, crusting, persistently itchy, painful, or different from nearby marks. Seek advice before using strong lightening products on an undiagnosed patch, especially if the skin is inflamed or broken.

Ask what pattern the patch follows, whether inflammation or scale is present, and what diagnosis is being treated. Discuss sun protection, the chance of temporary irritation or darkening, how progress will be judged, and when a procedure should be postponed.
