- Any food allergy, intolerance, restriction or special diet that, in the opinion of the investigator, could contraindicate the subject's participation in this study.
- Known or suspected allergy/hypersensitivity to lidocaine or prilocaine, known history of sensitivity to local anesthetics of the amide type or to any other component of the product, other related products, or any inactive ingredients.
- Tattoos or broken and/or damaged skin at the application areas.
- Active skin diseases like psoriasis or atopic dermatitis, as judged by the investigator.
- Scarring at the anterior part of the thighs.
