Small Black Dots on Face: Causes and Concerns for Acne Patients - Dermatology

Small black spots appear on the face?


I would like to ask about my long-standing acne issue.
I am currently receiving treatment (oral medication and topical ointments).
Recently, I noticed about 10 small black spots on my face, which appear to be moles, approximately the size of half a sesame seed.
I would like to know if this is a sign of an illness or if it could be caused by something else.
Thank you!

The appearance of small black dots on the face, especially for someone with a history of acne, can be concerning. These dots could potentially be a variety of things, and understanding their nature is essential for determining the appropriate course of action.

Firstly, it’s important to differentiate between various types of skin lesions. The small black dots you describe could be seborrheic keratosis, which are benign growths that often appear as small, dark spots on the skin. They are common in adults and typically do not require treatment unless they become bothersome or are cosmetically undesirable. Another possibility is that these dots are actually blackheads, which are clogged pores filled with sebum and dead skin cells that have oxidized and turned dark. This is particularly relevant for someone with a history of acne, as blackheads are a common form of acne.

In some cases, these small black dots could be moles (nevi) or even skin tags, which are also benign but may require monitoring for changes in size, shape, or color. If they are new and have appeared suddenly, it’s worth noting that any changes in the skin should be evaluated by a dermatologist, especially for individuals with a history of skin issues like acne.

Given your ongoing treatment for acne, it’s also possible that the medications you are using could contribute to changes in your skin. Certain topical treatments can lead to irritation or changes in pigmentation, which might manifest as dark spots. It’s crucial to discuss any new skin changes with your healthcare provider, as they can assess whether these dots are a side effect of your current treatment regimen or if they are unrelated.

Additionally, lifestyle factors such as sun exposure, diet, and skincare routines can also play a role in the appearance of new skin lesions. For instance, excessive sun exposure can lead to hyperpigmentation, which may appear as dark spots on the skin. It’s advisable to use sunscreen daily to protect your skin, especially if you are undergoing treatments that may make your skin more sensitive.

In conclusion, while the small black dots on your face may not necessarily indicate a serious health issue, they warrant further investigation. It’s essential to consult with a dermatologist who can provide a thorough examination and possibly recommend a biopsy if there is any suspicion of malignancy. They can also guide you on the best treatment options to address both your acne and any new skin concerns. Regular follow-ups and open communication with your healthcare provider are key to managing your skin health effectively.
