3 Those who are allergic to fruit acid solution: patients with allergic dermatitis at the treatment site; those with bacterial or viral infectious skin diseases (such as herpes simplex, common warts) on the face; patients with immunodeficiency diseases; orally within 6 months Or external use of retinoids.
