Hi,
Thank you for your question and pictures. From the photos and in the absence of any history provided, these tiny bumps appear to look like closed comedones (commonly known as "whiteheads").
Some could also be milia, and less likely, syringoma. A doctor will need to ask you more questions such as whether these bumps are itchy/painful, whether you are on any oral or topical medications, your current skincare regime etc to be able to diagnose and manage this most appropriately.
Comedonal acne and milia respond well to non-invasive treatment such as medical-grade vitamin A derivative creams.
Stubborn ones may be extracted, treated with chemical peels and/or lasers too. Do speak to your doctor to find out more regarding these procedures. Your doctor may also suggest you make some changes to your skincare regime to prevent new ones from forming.
Best regards,
Dr. Joanna Chan
