why black spots appear on skin - #17882
I am really confused and a bit worried about something that's been happening with my skin. A couple weeks ago, I noticed these black spots appear on my arm out of nowhere. They’re not raised or itchy, just these dark spots. At first, I thought it was just a bruise or something, but it didn't go away. Then I saw more of these spots on my back and legs too. I'm in my late 30s, and I honestly don't remember anything happening that would cause this. Like, why do black spots appear on skin all of a sudden? I've tried some over-the-counter creams, thinking maybe it was some sort of age spot or sun damage, but they just don’t seem to fade. I really don't have a history of skin conditions or anything like that. This whole thing is just stressing me out! I've read online about why black spots appear on skin but it's all kinda vague and scarey honestly. Some websites say they could be normal, and others say they could mean something serious. Should I just see a doctor, or do these black spots on skin usually clear up on their own? Ugh, I just want to know what the deal is and if I need to be worried!

Doctors' responses
Black spots on the skin can arise from different causes and while they can be worrying, it’s not always a sign of something serious. One common cause is post-inflammatory hyperpigmentation, where your skin darkens after an irritation, injury, or inflammation—even if it seems minor or you don’t remember it happening. Sun exposure, certain medications, or hormonal changes can also result in these spots. Alternatively, they might be age spots, also known as liver spots, typically resulting from cumulative sun exposure over years. Other potential causes could be melasma or lentigenes, conditions that result in dark patches on the skin due to sun exposure, genetics, or hormonal changes. However, some underlying health conditions or nutritional deficiencies might lead to hyperpigmentation. If the spots are spreading, persistent or changing in appearance, it’s wise to consult a dermatologist to rule out something more significant, like skin cancer—for instance, melanoma—which can appear as dark spots. In particular, any asymmetry, irregular borders, multiple colors, diameter changes, or evolving lesions should be evaluated promptly. It’s good that over-the-counter treatments were attempted, but since they’ve not improved the condition, professional assessment would offer more specialized interventions. Based on a clinical evaluation, the dermatologist might recommend treatments such as prescription creams, cryotherapy, or laser therapy, depending on the root cause. Documenting these spots in terms of changes or rapid development can be useful for your appointment. In terms of home remedies, while waiting for your appointment, protecting your skin with sunscreen every day is a practical step. Hydration and maintaining a healthy, balanced diet with adequate vitamin intake can support overall skin health, but should not replace professional evaluation if needed.
