While eyelash services are generally safe when performed by trained professionals, there are potential side effects to be aware of. Some individuals may experience mild irritation or allergic reactions to the products used during the procedures. Redness, itching, or swelling can occur, but these symptoms are usually temporary. It's essential to inform your technician of any known allergies or sensitivities before your appointment. At Elite Styles Salon and Med Spa, we use high-quality, hypoallergenic products to minimize any risks.
