Permanence of spider vein treatments

Does anyone know if spider vein treatments are permanent? I've heard mixed things about whether the veins can come back after treatment, and I want to understand what I'm getting into before spending money on procedures. Also, are there things you need to do long-term to prevent new ones from forming?

The treated veins themselves won't come back because they're essentially destroyed and absorbed by your body. However, new spider veins can develop over time, especially if you have underlying factors that contributed to the original ones, like genetics, hormonal changes, or lifestyle factors. So while the treatment is permanent for those specific veins, it doesn't prevent new ones from potentially forming in other areas. Long-term prevention involves managing risk factors where possible, staying active to keep blood circulation healthy, maintaining a healthy weight, avoiding prolonged standing or sitting, and wearing compression stockings if recommended. Sun protection is also important for facial spider veins. Most people find that even if new veins appear years later, they're usually minor and easy to treat with touch-up sessions.

I was really worried about this same thing before getting my treatment done. The specialist I worked with was upfront about the fact that while treatment of spider veins on the legs would permanently eliminate the existing veins, my genetics and lifestyle could contribute to new ones developing down the road. That said, I had my treatment done about three years ago and haven't seen any significant new veins appear. I think a lot of it comes down to taking care of yourself afterward. I've been better about regular exercise, I elevate my legs when I'm sitting for long periods, and I wear sunscreen religiously. The peace of mind knowing that if new ones do appear I can just get them treated again is reassuring too. The initial results have held up really well for me, and I'm glad I didn't let the 'what if they come back' worry stop me from doing it.
