Delayed hypersensitivity reaction from microneedling twenty years after silicone fillers

ABSTRACT

Skin rejuvenation procedures have increasingly flooded the aesthetic market, one of which includes microneedling. In microneedling, multiple fine punctures of the skin are performed with a needle to induce neocollagenesis. Microneedling has increasingly been used to treat inflammatory acne, acne scarring, photodamaged skin, and even radiation dermatitis. We present a patient with a stable history of liquid injectable silicone (LIS) given 20 years prior who developed chronic periocular and facial hypersensitivity after undergoing microneedling at a medi-spa. Long-term steroids and immunosuppressants were needed for control. The patient’s severe reaction and resistance to treatment highlights the potential complications of microneedling administered by a non-medical professional in the setting of prior injectable silicone.
