I'm 19 and I've always had a few spider veins on my chest, but in the last year they've been progressing fast. Should I worry?

There is no need to worry! Spider veins are often
hereditary, and can be easily cured with sclerotherapy or other vein
treatments. You should definitely talk to a surgeon to get rid of those veins,
but I wouldn’t worry too much about it in terms of your overall health!

These are easily treated with lasers. I suggest seeing a cosmetic dermatologist with experience.  Best, Dr. Emer.

Thank you for your question.Telangiectasias on the face result from many factors including genetics, sun exposure, hormones, etc.Veins on the chest may be apparent because of light skin color, thin skin, skin texture and can be easily treated with sclerotherapy.See an ABVLM certified vein specialist.Dr. Karamanoukian

There is no need to worry. Majority of cases are familial and inherited, you can see a vascular surgeon if you want them treated. The treatment will depend on size and distribution

You should see a vein specialist for a venous evaluation.  Most of the time what you describe is due to genetics and can be treated simply with sclerotherapy or topical laser. However, occasionally there may be an underlying problem which would need to be evaluated.
