Female face models of all ages needed

Female face models of all ages needed for a range of skin care treatments.  Images will be taken for a brochure advising clients on the right products for age.  We are looking for models with excellent skin and high cheekbones.  Perfect symmetry is essential.  Models will be photographed individually in a studio setting.  Hair and make-up will be styled professionally.  Each model will be paid £300 for a four hour photographic shoot.  Prior modelling experience would be an advantage.  Images will be used as part of a digital marketing campaign.
