Diode made spider veins worse. I'm afraid of scarring. (Photo)

It’s important to distinguish between varicose veins and spider veins when choosing between laser therapy, sclerotherapy, and vein surgery. With two board certified vein specialists, our center uses a combination of visual examination, functional flow measurements, ultrasound, transillumination, and infrared light to map out vein networks prior to therapy. Lasers can be used to treat deep varicose vein insufficiency, vein perforators, and varicose veins. Sclerotherapy is ideal for spider veins and reticular veins. Whereas surgery is reserved for severely incompetent varicose vein segments.

Thank you for the question!  It is rather difficult to fully evaluate your situation without an in-person exam. It's likely that you're experiencing hyperpigmentation rather than spider veins. It can be treated with a topical ointment but you should see your physician first to determine the exact cause of discoloration. 
An in-person exam with a board-certified plastic surgeon is the best way to assess your needs and obtain expert medical advice. Best of luck!

The treatments as you have outlined have caused hyperpigmentation and this has to be addressed using topicals that are HQ based and non HQ based, See the link below for topicals that help reduce this effect. As well, it is important to avoid sun exposure.
