Blue/purple discolouration after lip filler treatment when cold or alcohol

It's possible that the blue/purple discoloration you're experiencing after lip filler treatment when exposed to cold or alcohol is due to a phenomenon called Raynaud's phenomenon.

Raynaud's phenomenon is a condition where the small blood vessels in the skin narrow in response to cold or emotional stress, causing a reduction in blood flow to the affected area. This can lead to a bluish or purple discoloration of the skin.

In some cases, lip fillers can trigger Raynaud's phenomenon, especially if they are injected near the blood vessels in the lips. The cold or alcohol exposure may then exacerbate the discoloration by triggering the already narrowed blood vessels.

However, it's also possible that the discoloration is a side effect of the filler itself. Certain types of fillers, such as those made from hyaluronic acid, can sometimes cause a bluish discoloration known as the Tyndall effect when injected too close to the surface of the skin. This effect can be exacerbated by cold or alcohol exposure.

If you're concerned about the discoloration, it's best to speak with your healthcare provider who can evaluate your symptoms and determine the cause of the discoloration. They may also be able to recommend treatment options to help alleviate the symptoms.
