E.3 | Principal inclusion criteria |
Signed and dated informed consent has been obtained.
Subjects with 5 to 20 clinically typical, visible and discrete AKs within a treatment area of
sun-damaged skin on the full balding scalp (the balding part of the scalp should be greater
than 25 cm2 and up to approximately 250 cm2).
Subjects at least 18 years of age.
