Lip filler reaction/migration? (Photo)

Thanks for your question. We do sometimes see late onset reactions in regions where dermal filler has been placed. However, the RHA brand of dermal fillers is the LEAST LIKELY to cause this reaction because their cross linking looks most like your body's natural HA cross linking. Two years out we would certainly expect the RHA 2 to have dissolved away already. So, it makes more sense to look for other causes of the symptoms first. I see a few white spots on your photo- these are likely Fordyce spots. These harmless, tiny (1 to 2 millimeter) white bumps inside the lips are visible sebaceous, or oil-producing, glands. I hope that helps.
