The main ingredient on the strips is polyquaternium-37, a film-forming, hairspray type ingredient—so it's basically a piece of gauze with a form of hairspray on it. The plastic-forming agent can get into the pores and possibly cause breakouts and irritation. The way these strips adhere, they can absolutely injure or tear skin and cause spider veins to surface. They are especially unsafe if you've been having facial peels; using Retin-A, Renova, AHAs, or BHA; or are taking oral vitamin A (isotretinoin) for acne; or if you have naturally thin skin or any skin disorder such as rosacea, psoriasis, or seborrhea.
