TA is within 5 cm of an incompletely healed wound or infected area of the skin., Patients not willing to abstain from sunbathing (including solarium) or any outdoor activities with intensive sun exposure without taking appropriate measures to protect the treatment areas during the study., Patients with a tendency to manipulate skin parts e.g. scratching., Pregnant or breast-feeding patients., Patients currently or within the past 4 weeks participating in another clinical study., Any previous randomization into this clinical study., Any suspicion of current drug and/or alcohol abuse., Patient is institutionalized because of legal or regulatory order., Dependency (as an employee or relative) to the sponsor/responsible CRO or investigator., Any condition that in the opinion of the investigator can influence the evaluation of the treatment, and other assessments., Hypersensitivity, intolerance or allergies against ingredients of Veregen® 10% ointment and/or Placebo ointment., AK lesions in the TA with atypical clinical appearance (e.g. TA contains massively hyperkeratotic and hypertrohic lesions (Olsen grade III AK), recalcitrant lesions, cutaneous horns, and/or lesions that had not responded to 2 previous cryotherapies)., Have received the following topical or physical treatments for any indication in the treatment area within the designated time period before treatment with study drug: a) Curettage, Photodynamic therapy, Topical inhibitors of Src tyrosine kinase signaling and tubulin polymerization (e.g.,Tirbanibulin) for/in a period of 12 weeks; b) Topical retinoids, Topical diclofenac preparations, Topical 5-fluorouracil preparations, Topical immunomodulators (e.g., Imiquimod) for/in a period of 6 weeks; c) Topical steroids, Cryo-, thermo- or chemodestruction, Surgical excision for/in a period of 4 weeks., Initiation of treatment with the following systemic treatments for any indication within 2 weeks before Baseline: Immunomodulators or immunosuppressive therapies, Diclofenac, Corticosteroids (oral or injectable), Inhaled corticosteroids (>1200 µg/day for beclomethasone, or >600 µg/day for fluticasone), Current or planned intake of high dosed oral green tea preparations for any reason, Current or planned application of dermal preparations with astringent effect on the TA, such as zinc paste or tannin-containing ointments/creams, Patients taking a drug with known potential for skin reactions must have taken it at a stable dose for at least 2 weeks prior to Baseline, except in cases where no previous skin reactions have occurred at any dose., Women of childbearing potential (WOCBP) will not be considered unless they use a highly effective method of contraception (failure rate of less than 1% per year) during the interventional period until 4-weeks PT (EoI, V9)., Within the TA, any suspicion of other malignant or benign skin tumors., History of a genetic skin-cancer disorder (e.g. xeroderma pigmentosum) and/or invasive tumor in the TA, such as a Merkel cell tumor, an invasive spinocellular carcinoma or a BCC (Basal Cell Carcinoma) and/or any skin cancer (suspected or diagnosed recently or within 5 years ago before screening)., History or evidence of skin conditions other than AK that would interfere with evaluation of the study medication (e.g. eczema, unstable psoriasis)., Patients having any significant physical abnormalities in the TA that may cause difficulty with examination or AK assessments (e.g. tattoes, scars, hyperpigmentation,
