Pathology background
Acne is a long-term skin condition characterized by areas of blackheads, whiteheads, pimples, greasy skin, and possibly scarring. The resulting appearance may lead to anxiety, reduced self-esteem, and in extreme cases, depression or thoughts of suicide.
That’s the reason why preclinical models of acne are needed for testing efficacy prior to clinical testing.
These models include hamster and mouse preclinical models.
IMAVITA is able now to propose operational efficacy testing service in this pathology.
