Ischemia from Vascular Occlusion. Any suggestions? (Photo)

I'm really sorry that you are experiencing this. I have found that professionally performed microneedling combined with the topical application of agents, such as brimonidine, oxymetazolene and tranexamic acid, can be helpful in reducing redness and discoloration following a variety of prior traumas to the skin. As an aside, I am not surprised at the lack of success of the lasers, as I almost daily urge my readers to exercise a healthy dose of "buyer beware" when it comes to considering these expensive "bells and whistles" devices, since the hard science to support them lags well behind the heavy marketing to promote their use. Make sure to consult with an experienced, board certified cosmetic dermatologist and best of luck.

Im sorry for your persistent problem. I suspect this is due to the revascularization of the tip with multiple small vessels that give the red appearance. In my opinion, over time it will resolve on its own, I would be fearful to use any vascular laser because this likely represents healing and possibly you could harm blood flow in the newly vascularized area.
