Do spider veins ever go away alone?
A spider vein package often comes with a promise about what the veins will do if you leave them alone. Before you sign, hold that promise up against what a medical source actually says.
Do they fade without treatment, or not?
Harvard Health, published at www.harvardhealth.org, says: "Spider veins may be permanent or may disappear on their own after a period of months, especially if they are caused by pregnancy or certain medications." The word "may" appears twice, so the source commits to neither outcome. The only causes it connects to fading are pregnancy and certain medications. You can read the Harvard Health entry on spider veins to see that sentence in context.
Where a sales pitch can overreach
A salesperson who says spider veins never go away is claiming more than that sentence supports. So is one who says they always clear up by themselves. If either claim shows up in a quote, a brochure or an agreement, treat it as something to check and not as a fact.
What to put in writing before you sign
Ask the provider to write down what they believe caused your veins, since the source ties fading to particular causes. Ask for the expected timeframe in the same document and compare it with the "period of months" the source mentions. The guide on why leg veins appear and how dermatologists treat them is useful background for that conversation.
If you are comparing consultations around Ann Arbor, Michigan, bring that one sentence with you. Ask each provider which part of it their estimate relies on.
